Google Docs isn't the only place getting AI-powered summarization. Google Sheets now brings this capability through Gemini, letting you condense text-heavy data right within your spreadsheets.
Most spreadsheets contain more than just numbers. You'll find customer feedback, project notes, survey responses, and other text content mixed in. Manually reading through all that to find the main points is tedious—which is exactly where Gemini's AI Summarize text tool comes in handy. This guide walks you through condensing text in Google Sheets efficiently.
Getting Started with AI Summarize in Google Sheets
Step 1:
Set up your Google Sheets spreadsheet as usual. You can create a dedicated column or row where you want to place your summarized content.
At the location where you want to insert the summary, click on Gemini and select Summarize text. Gemini automatically analyzes the text you've selected—whether it's a single cell or your entire data range—and generates a concise summary.
Here's what's interesting: you don't need to write any prompts or commands. Just pick the right data and select the Summarize text tool, and Gemini handles the rest.
Step 2:
Give Gemini a moment to process your data and content. Once it finishes, you'll see the summarized version appear on your screen. Gemini's summarization tool extracts the most essential information from your spreadsheet, making it easier for anyone to grasp the key points at a glance.

LM Studio has become the go-to application for running large language models locally on your machine. It's intuitive, polished, and requires zero terminal knowledge — just a few clicks and you're running any AI model you want. For anyone seeking the benefits of local LLM deployment, it's genuinely one of the best tools out there. But here's the thing: despite being free, LM Studio isn't open-source. While some components carry open licenses, the application itself remains proprietary software. For a tool that could become central to your entire local AI workflow, the risk of unexpected licensing changes whenever the parent company decides is a concern that drives many users elsewhere — straight to Jan.
Why Jan is a genuinely competitive LM Studio alternative
Jan is a desktop application that lets you run large language models entirely offline — functionally similar to LM Studio, but with a crucial difference. It's not just completely free; it's fully open-source with all code available on GitHub. No licensing surprises. No proprietary lockdowns. No fine print to worry about.
The interface mirrors ChatGPT's design, which lands somewhere between refreshing and derivative depending on your preference. What's interesting here is that this deliberate design choice makes Jan feel immediately familiar to anyone exploring local AI for the first time. The interface is clean, organized, and requires zero developer expertise to navigate. You get a chat window, a model hub, and straightforward settings — exactly what you need.
If you're switching from LM Studio, the model library will feel right at home. You can browse and download popular open-source models — Llama, Gemma, Mistral, Qwen, DeepSeek, and many others — directly within the application. Each model includes tags indicating hardware compatibility and performance expectations, so you'll know upfront whether it'll run smoothly on your setup.
Jan interface open on Windows 11
Jan includes an OpenAI-compatible API server. This is genuinely powerful — you can point other tools like Cursor, Open WebUI, custom scripts, or applications you're developing at Jan's local server and interact with it exactly as you would with OpenAI's API. Perfect for prototyping and testing code before you commit to paid API calls. The server also supports CORS out of the box, making web project integration seamless.
Performance-wise, Jan sits right alongside LM Studio. Token usage is comparable, inference engines work essentially the same way, and you get built-in extensions if you want to expand functionality further.
The privacy advantages are substantial and real
Local models, zero cloud, zero surprises
Jan and LM Studio open on a laptop
Running AI locally has always been a privacy-first choice, but Jan takes that commitment further. Everything stays on your machine: your preferences, chat history, model parameters, and the models themselves. No account creation. No telemetry worries. No cloud dependency. You get a completely isolated AI experience if that's what you want.
There are two tradeoffs here. First, you're limited by your hardware's capabilities. Second, open-source LLMs aren't always competitive with commercial cloud models — they won't handle every task equally well. That's just reality.
Jan solves this elegantly by supporting remote APIs from OpenAI, Anthropic, Claude, and others. You don't have to choose between local and cloud — the default is local (and private), but you can switch to cloud models whenever a task demands it. It's flexibility without compromise.
Jan isn't perfect yet
Jan's GPU configuration settings
Coming from LM Studio, you'll notice missing depth in certain areas. GPU layer configuration is less intuitive here than in LM Studio. Document analysis features also feel more polished in LM Studio. Jan is catching up, but if you're someone who tweaks every inference parameter manually, LM Studio still has the edge.
If you're a command-line person, Ollama outperforms both LM Studio and Jan. Startup speed-wise, these two GUI-based LLM tools are roughly equivalent but slower than Ollama. Jan occupies the middle ground: more transparent than LM Studio, more user-friendly than Ollama.
Jan is quietly becoming the default LM Studio replacement
There's little friction in switching from LM Studio to Jan. The transition takes minimal time, and your models and data migrate smoothly. The real difference is ownership. With Jan, you control your entire local AI stack completely. There won't be sudden licensing changes or unexpected policy shifts catching you off guard.
In everyday use, Jan delivers everything LM Studio does, plus the peace of mind that comes with actual software ownership. You get all the control and advantages you need without any hidden complications down the road.
Description: Explore why Jan is gaining traction as a privacy-focused, open-source replacement for LM Studio in local AI workflows.
Here's our complete ranking of the 9 best machine learning courses available in 2026, evaluated across depth of hands-on projects, curriculum freshness, and real student outcomes.
We ranked these courses using four key criteria:
Accessibility — how well-suited the course is for its intended audience and ease of entry
Hands-on depth — whether students actually build, train, and evaluate real models rather than watching demos
Instructor expertise — the quality and experience of the teaching team
Tangible student outcomes — demonstrated results from people who've completed the course
Our evaluation draws directly from course content across DataCamp, Microsoft Learn, Kaggle, fast.ai, Google, Stanford Online, MIT OpenCourseWare, Udemy, and edX, current as of April 2026.
1. Supervised Learning with scikit-learn — DataCamp

The pathway covers: exploratory data analysis with Python; training and evaluating regression and classification models; clustering; and tuning plus testing deep learning models. Lessons are short, focused units with interactive sandboxes — no Azure account signup required to start. The trade-off is less programming flexibility compared to Coursera or Kaggle (modules lean heavily into Azure ML SDK), but if you want both ML fundamentals and credentials tied to Microsoft's cloud ecosystem, this is the natural choice.
Kaggle's "Intro to Machine Learning" is an excellent free option if you want bite-sized lessons connected to real datasets and a pathway into competitions.
Level: Beginner
Duration: Around 3 hours
Cost: Completely free
Best for: Learners who want to get up to speed quickly and then dive into Kaggle competitions using real datasets
Seven compact lessons cover the standard ML workflow: how models work, basic data exploration, building a first model with decision trees, model validation, underfitting and overfitting, random forests, and submitting to Kaggle competitions. Each lesson pairs brief explanations with hands-on exercises inside Kaggle Notebooks, so you're coding immediately.
fast.ai's "Practical Deep Learning for Coders" takes a different philosophy: build something that works first, understand the theory later. It's ideal if you're comfortable coding and want results quickly.
Level: Intermediate (requires ~1 year of programming experience)
Duration: ~20 hours of video across 7 lessons; actual project work takes considerably longer
Cost: Completely free
Best for: Programmers who want to deploy a working deep learning model in the first week, then gradually understand the underlying principles
Taught by Jeremy Howard. This course inverts traditional teaching: in lesson one, you're already training a modern image classifier on your own data before anyone explains neural networks. Later lessons peel back the layers of complexity. The current version uses PyTorch, fastai, Hugging Face Transformers, and Gradio for model deployment.
Google's "Machine Learning Crash Course" is an excellent free introduction written by the engineers who actually build ML at scale. It includes interactive tools that build genuine intuition for how models actually behave.
Level: Beginner to Intermediate
Duration: ~15 hours for foundational modules; longer if you explore advanced topics and LLM content
Cost: Completely free
Best for: Engineers at any level wanting a coherent, current overview of ML with deep dives into LLMs and real-world ML systems
Originally designed for Google's internal teams, now public. The 2024 update significantly expanded the curriculum. Core ML modules (linear regression, logistic regression, classification, artificial neural networks, embeddings) are now paired with advanced sections on real ML systems, generative AI, large language models, and ML fairness. Every lesson includes interactive Colab notebooks and visualization tools where you can tweak parameters and watch models respond. It strikes a rare balance between breadth and depth.
Stanford's CS229 is the choice for anyone serious about the mathematics behind ML algorithms — think graduate-level rigor in a publicly available format.
Level: Advanced (requires linear algebra, multivariable calculus, probability, and Python)
Duration: ~20 lectures at roughly 80 minutes each, plus problem sets
Cost: Video lectures free on YouTube; professional certificate version through Stanford Online carries tuition
Best for: Engineers, researchers, and graduate students who want rigorous mathematical proofs and derivations instead of intuition-based explanations
CS229 covers supervised learning (linear models, GLMs, SVMs, kernel methods), unsupervised learning (k-means, EM, PCA, ICA), deep learning, and reinforcement learning — all with mathematical rigor throughout. This is for people who want to understand why algorithms work, not just how to use them. The real concern is pacing; if linear algebra isn't fresh, expect to slow down.
7. 6.036 Introduction to Machine Learning — MIT OpenCourseWare
MIT's 6.036 is a high-quality free option if you want university-level rigor focused on algorithms and the mathematics behind them.
Level: Intermediate to Advanced (requires Python, linear algebra, and basic probability)
Duration: ~24 lectures plus 12 problem sets and labs
Cost: Completely free
Best for: Self-directed learners who value MIT-grade academic rigor and prefer proofs and theory over building real-world applications
Topics include linear classifiers, the perceptron and perceptron convergence theorem, logistic regression and gradient descent, feature representation and regularization, artificial neural networks and backpropagation, convolutional and recurrent networks, Markov decision processes, and reinforcement learning. Lectures and problem sets are the actual materials used on campus, so they're authentic but sometimes less polished than commercial courses.
"Machine Learning A–Z" by Kirill Eremenko and Hadelin de Ponteves is a project-driven course on Udemy that's attracted over a million enrollments for good reason: it's practical and comprehensive.
Level: Beginner to Intermediate
Duration: ~44 hours of video plus templates and exercises
Cost: $15–$85 USD depending on Udemy sales
Best for: Learners who want one instructor walking them through a diverse set of ML algorithms, each with reusable code templates
The course spans regression, classification, clustering, association rule learning, reinforcement learning, NLP, deep learning, dimensionality reduction, and model selection. Each topic includes implementations in both Python and R with downloadable code templates. Because the scope is broad, individual topics don't go as deep as specialized academic courses; however, this "catalog" format is genuinely useful when you need to decide which algorithm fits your problem. The course is regularly updated.
9. CS50's Introduction to AI with Python — Harvard (edX)
Harvard's CS50AI on edX is excellent if you want to understand machine learning within the broader context of artificial intelligence — including search, knowledge representation, reasoning under uncertainty, and more.
Level: Intermediate (assumes completion of CS50P or equivalent Python experience)
Duration: ~7 weeks at 10–30 hours per week
Cost: Free to audit; $239 for verified edX certificate
Best for: Learners wanting a comprehensive AI foundation beyond just machine learning, from a respected university
Instructors: Brian Yu and David J. Malan. The course covers search algorithms (BFS, DFS, A*, minimax), knowledge representation and propositional logic, probability and Bayesian networks, optimization, machine learning (supervised and reinforcement), artificial neural networks, and natural language processing. Each unit includes a substantial Python project: tic-tac-toe AI, PageRank implementation, handwritten digit recognition, and a question-answering system. You get breadth across AI, not just ML depth.
Here's the core difference: chatbots wait for users to ask questions. AI agents, on the other hand, are designed to take action and solve problems.
That distinction might sound subtle, but it unlocks an entirely different approach to AI. Instead of asking AI to summarize a document and manually transferring the results elsewhere, you can program an agent to break down tasks, leverage available tools, make decisions within guardrails, and execute a complete chain of related actions.
Both leading AI companies and the research community are paying serious attention to this concept. What's interesting here is that mastering AI agents doesn't require diving into complex software systems or elaborate automation frameworks from day one. The real starting point is understanding exactly what an AI agent actually does.
What exactly is an AI agent?
There's no single universally accepted definition yet. At its core, an AI agent is an application that achieves specific goals by independently selecting actions, using external tools or systems when needed, and adjusting based on the results it receives.
Anthropic describes agents as systems where the model can flexibly control how tasks are executed and which tools get used, rather than just following a predetermined sequence of instructions. OpenAI makes a similar distinction—what sets agents apart is their ability to complete multi-step tasks with the help of tools.
Here's a beginner-friendly example: information research. A standard chatbot can summarize content based on what's provided in the conversation. An agent, however, could be programmed to perform multiple consecutive actions: search approved data sources, gather information, analyze it, create a response, and send the result to another system.
That said, agents aren't always accurate. Far from it.
The real skill is in task design
Mastering AI agents doesn't mean knowing every AI platform out there. What matters is understanding how to break a useful task into appropriate components.
Picture a small online store fielding customer questions regularly. An agent could handle this sequence: understand what the customer needs, identify required data, access an approved product database, craft a response, and escalate unusual cases to a human. Each step is a potential failure point. An outdated database might serve wrong information. The agent might misunderstand the request and pull from the wrong data source. And if you give the system too much autonomy, a simple automation could become an expensive mistake.
This is why Anthropic's guidance on agentic systems emphasizes keeping architecture simple, designing tools clearly, and seriously questioning whether you actually need an agent.
Focus on workflow before full automation
New builders often make the same mistake: trying to create a fully autonomous agent right away, before they understand how to automate simple tasks.
A better approach is to start by identifying a repetitive task. Then map out your inputs, desired outputs, required tools, and points where human approval is needed. Only after these elements are crystal clear should the system gain more autonomy.
Example: a machine learning process that sorts incoming files is far easier to test and validate than an autonomous agent given full control over an entire business workflow.
Here's what you need to remember: more autonomy means more uncertainty. Starting with a controlled workflow gives you better visibility into what's actually happening inside the system.
Tools are what give agents their power
The AI model alone can't do everything. An agent's capabilities expand when it can access tools like databases, search engines, calendars, programming languages, or business applications.
But here's the trade-off: each new tool also increases the attack surface of your entire system. Tools need to be purpose-built and come with appropriate restrictions.
For instance, an agent designed only to read information shouldn't also have permission to modify or delete that data.
What should beginners learn first?
Building AI agents can feel overwhelming given how fast this ecosystem is evolving. But the foundational knowledge? That's surprisingly stable.
Start by understanding how language models interpret and follow instructions. Then learn about APIs and structured data. Practice describing tasks with precision. Pick up at least Python or another programming language.
Most importantly, learn how to verify whether your agent's output is actually correct.
This is where people cut corners. One successful run doesn't mean the system is reliable. Both Anthropic's research on agentic systems and OpenAI's agent guidance stress the importance of testing, tool design, and security.
The essentials for building AI agents
Mastering AI agents isn't about giving AI free rein to do everything. The right approach is finding a task that needs multiple actions but can still be safely controlled—give the system only the permissions it actually needs, and continuously verify that results match your original goals.
Deploy incrementally. Test rigorously. Only grant additional autonomy when you have a solid reason to do so.
It's not as flashy as the vision of a completely autonomous AI system, but this is how trustworthy AI agents actually get built.

If you're picking your first AI image generation tool, you're almost certainly weighing Midjourney against Leonardo AI. Both can transform text prompts into stunning visuals, but they're built for different kinds of users. Choose the wrong one, and you might waste money or spend unnecessary time getting up to speed.
Here's what actually matters most when you're just starting out.
Cost and Free Options
This is the biggest gap between them. Leonardo AI offers a free tier with daily tokens, letting you experiment and generate images without spending a dime. Midjourney, on the other hand, has no free plan—you need to pay to get started. What's interesting here is that this single difference shapes who should use what right from the beginning.
If your budget is tight, Leonardo AI is the obvious starting point.
Image Quality
Midjourney is known for producing visually stunning, artistically rich images with immediate "wow factor." It remains one of the top standards for artistic-style generations across the board.
Leonardo AI delivers excellent quality too, and it's improving rapidly. But when it comes to overall aesthetic appeal and lighting control, Midjourney still has the edge.
Style and Creative Control
Leonardo AI gives you multiple models, style presets, and deep customization options. This really shines when you're creating game art, character designs, or product images.
Midjourney has a very distinctive, striking visual signature—but that same signature is harder to bend to your will. If you want flexibility and the ability to tweak results, Leonardo AI is more versatile.
Built-In Editing Tools
Leonardo AI packs several editing features directly into the platform: upscaling, background removal, AI Canvas, and image inpainting. Midjourney stays laser-focused on image generation itself.
So if you want to generate and refine images in a single application, Leonardo AI offers more toolkit depth.
Ease of Use
Both platforms now feature clean web interfaces: type your prompt, hit generate, and wait for results. Midjourney's workflow is slightly more streamlined, while Leonardo AI offers more options—which means more learning resources too.
For beginners, both are reasonably approachable.

Go with Leonardo AI if you're budget-conscious, want free daily image generation, and appreciate having lots of control options plus built-in editing features.
Go with Midjourney if you're after the absolute best artistic image quality and don't mind paying for it.
Here's the real concern for most beginners: the smartest move might be to start free with Leonardo AI to learn prompt writing, then upgrade or add Midjourney later when you're ready to push image quality even higher. The real benefit is that these two tools actually complement each other well—you don't have to pick just one forever.
Whichever path you choose, remember that AI-generated images can become income. You can sell prints on Etsy, use print-on-demand services, or land graphic design gigs on Fiverr.

When someone asks how to run a large language model locally, Ollama has become the default answer—and rightfully so. It's user-friendly, works across platforms, and abstracts away enough complexity that you can have a working model up and running in minutes. llama.cpp powers countless local AI applications too, especially for GGUF-format models, so neither tool is going anywhere.
But here's the catch: "easy to use" stops mattering once local models become part of your actual workflow. Suddenly you care about API serving, batch processing, structured outputs, cache behavior, Mac-specific optimizations, mobile deployment, or whether you're quietly wasting performance. While most people still think Ollama is the path of least resistance to get started, it's rarely where they want to stay when building something serious.
The alternatives are more complex, sure. But they hand you back control over the parts Ollama tries to hide. If you're running agents, routing multiple applications through the same model, working on a Mac, or trying to make a consumer GPU actually function like a real inference box, then the runtime becomes just as critical as the model itself.
vLLM and SGLang: Turning local models into infrastructure
vLLM should be your first stop when you want a local model behaving less like a desktop app and more like an inference service. It offers OpenAI-compatible APIs, high-throughput inference, continuous batching, prefix caching, block-wise prefilling, structured outputs, tool-calling parsers, and support for multiple quantization formats.
These features matter hugely when your model gets called by code, agents, RAG experiments, or multiple applications simultaneously. A single prompt in the terminal doesn't need much scheduling logic. But a local endpoint hit repeatedly? That absolutely does. Especially when those requests share context, run for extended periods, or risk wasting VRAM on cache management.
vLLM's headline feature is PagedAttention—it manages the model's key-value cache far more efficiently. The goal is preventing GPU memory from becoming the bottleneck when you've got many concurrent requests running or when context gets large. This doesn't speed up every local setup, but it's exactly why vLLM shows up everywhere online, particularly in higher-throughput deployments.
SGLang sits in the same category but with a different bent. Its strength lies in structured generation, templated prompts, and agent-like workloads. Features include RadixAttention for prefix caching, decode-prefill separation, speculative decoding, continuous batching, paged attention, block-wise prefilling, tensor and expert parallelism, and multi-LoRA batching.
Free-form text works fine in a chat box. It becomes a problem when your program expects JSON, a schema, or a tool call in a specific format. SGLang exists for repeatable prompts, constrained outputs, and cache reuse—all much easier to manage when the model is controlling tools rather than just answering questions.
You won't install either of these before getting comfortable with simpler tools. They demand setup work and assume users have some baseline knowledge. But they become invaluable when other software requires infrastructure-grade endpoint configuration. Once a local LLM becomes the backend infrastructure for your home lab, vLLM and SGLang fit the bill much better.
vMLX: The native Mac answer for serious local inference
Apple MLX description shown in LM Studio tooltip when hovering over the MLX icon
Mac users have always had a different story when it comes to local LLMs. Apple Silicon's unified memory makes large models surprisingly practical on laptops, but the software stack isn't the same as Linux machines with Nvidia GPUs. You can run llama.cpp with Metal and it works fine. But there are solid reasons to want tools built on Apple's stack from the ground up.
vMLX is interesting because it aims for an experience closer to what users want from Ollama or LM Studio, while borrowing ideas from more professional data-processing platforms. It mentions prefix caching, paged KV cache, continuous batching, and MCP tools. That's a fundamentally different approach from "download a model and chat with it," which is why it deserves more attention than just being another Mac wrapper.
MLX is Apple's array-processing framework for Apple Silicon, featuring lazy computation, dynamic graphs, CPU/GPU execution, and unified memory—where arrays live in shared memory. MLX-LM adds text generation, Hugging Face integration, quantization, and fine-tuning, while MLX-VLM includes vision-language models on the same foundation. vMLX is the application-level tool, while MLX-LM and MLX-VLM are lower-level options when you want closer model access. To be honest, none of this is a perfect replacement for vLLM or SGLang, but it's excellent if you're a Mac user.
Think of vMLX as the native Mac path through the local LLM world, not some awkwardly ported CUDA tool running on Apple Silicon. The memory model, GPU stack, and app expectations are different enough that native tools like this genuinely deliver benefits.
MLC-LLM and ExLlamaV3: Hardware-specific solutions
Vicuna-7B model running on Samsung Galaxy S23 Ultra, demonstrating on-device AI power
MLC-LLM is built on machine learning compilation and deployment across diverse platforms. It supports web browsers via WebGPU and WASM, iOS and iPadOS through Metal on Apple's A-series GPU, and Android through OpenCL on Adreno and Mali GPUs.
What's interesting here is that MLC plays a different role than typical server-based runtimes, though it can still serve OpenAI-compatible APIs. It's built for more specialized use cases. WebLLM runs inference directly in the browser with WebGPU acceleration—no server required. It also supports streaming, JSON mode, and structured JSON generation.
MLC isn't the right fit for one large model serving a home lab with multiple applications. Its appeal is deployment to places that don't look like typical LLM hosts: browsers, phones, tablets, and embedded apps. It targets a completely different flavor of local AI project than vLLM and SGLang.
ExLlamaV3 goes the opposite direction. It's the current iteration of the ExLlama line after ExLlamaV2 was archived, and it's basically an inference library purpose-built for running LLMs on modern consumer GPUs. The priorities are fitting the model, keeping context usable, avoiding VRAM waste, and hitting acceptable speeds without enterprise hardware.
EXL3 quantization format, tensor and expert parallelism for consumer hardware, continuous dynamic batching, speculative decoding, cache quantization, multimodal support, and LoRA backing all exist toward that goal. TabbyAPI also gives it an OpenAI-compatible server, so it can still slot into applications expecting a standard local endpoint.
Beyond the usual suspects: Other runtimes worth knowing
If you're just deploying local language models, Ollama and llama.cpp are solid choices to start with and stick with. But if you want more, there's an entire ecosystem to explore—tools that might fit your specific needs better. MLC and ExLlamaV3 address different problems, but both are more specialized than Ollama. MLC handles deployment to unusual platforms or devices (difficult to target conventionally). ExLlamaV3 helps squeeze maximum performance from commodity GPUs (for individual users). These aren't first recommendations for beginners, but they become essential when hardware or deployment environment starts dictating what your runtime can do.
There's also llama-swap—part of llama.cpp's model serving toolkit—useful if you're operating multiple local servers compatible with OpenAI or Anthropic and need a routing layer between them. Then you've got TensorRT-LLM, Nvidia's optimization solution for Nvidia cards; LMDeploy, a genuine model deployment and serving toolkit; Lemonade, a model serving platform optimized for AMD hardware; KTransformers, handling inference on hybrid CPU/GPU systems; and LocalAI, supporting diverse data types and hardware platforms.
Ollama remains the tool to recommend for newcomers. llama.cpp remains foundational—it deserves more respect than just being a simple tool, since it can accomplish substantial tasks on its own. But the real concern is this: when local models become part of your actual workflow, the runtime stops being a mere middleman. Suddenly the server, caching, batching mechanism, quantization strategy, and backend platform decide what you can actually build.
Description: Explore specialized LLM runtimes like vLLM, SGLang, vMLX, and ExLlamaV3 that go beyond Ollama's simplicity for production workloads.
