Ollama

Devstral Small 2 is a 24B-parameter coding model from Mistral AI that scores 68% on SWE-bench Verified and runs on a single 24GB GPU or a Mac M-series with 32GB unified memory — making it the first cloud-grade coding agent most developers can realistically self-host. This guide covers three setup paths: Ollama for beginners, vLLM for production teams, and llama.cpp for CPU-only or low-VRAM machines. What Is Devstral Small 2? Devstral Small 2 is Mistral AI’s open-weight coding specialist, released December 10, 2025 under the Apache 2.0 license. With 24 billion parameters and a 256K-token context window, it achieves 68.0% on SWE-bench Verified — a real-world benchmark measuring a model’s ability to resolve open GitHub issues autonomously. That puts it on par with models up to five times its parameter count, including closed-source proprietary systems. Because it ships under Apache 2.0, you can run it locally with no API fees, no data leaving your machine, and no usage restrictions — even in commercial projects. The model is fine-tuned specifically on agentic coding workflows: reading multi-file codebases, writing patches, running tool calls, and self-correcting from test failures. Devstral Small 2 outperforms Qwen 3 Coder Flash (30B) despite being a smaller model, and its larger sibling Devstral 2 (123B) hits 72.2%, compared to Claude Sonnet 4.5’s 77.2% — at up to 7x lower cost per coding task. For teams or individuals who need a capable coding agent without cloud dependency, Devstral Small 2 is the most practical choice available today. ...

Ollama has become the default way to run local AI models in 2026: 52 million monthly downloads, 169,000+ GitHub stars, and 42% of developers now running at least some LLM workloads entirely on-device. The hard part is no longer installing Ollama — it is choosing which model to pull for coding. This guide ranks the eight best Ollama models for coding based on benchmark data, VRAM requirements, and practical performance on tasks developers actually face. ...

Aider + Ollama gives you a fully local AI pair programmer that costs nothing to run, sends zero code to any cloud, and works completely offline — set it up once and you have a private coding assistant running on your own hardware. Why Local AI Coding Matters in 2026 Local AI coding matters in 2026 because the economics and privacy calculus have fundamentally shifted. Stack Overflow’s 2025 developer survey found that 84% of developers use or plan to use AI coding tools, with 51% using them daily — but cloud AI subscriptions add up fast. GitHub Copilot runs $10–19/month per seat; Claude API costs $15–75 per million tokens at the high end. For teams or solo developers processing large codebases, those costs compound quickly. Meanwhile, 91% AI adoption across 135,000+ developers in active repos (DX Q4 2025) means organizations are scrutinizing what code actually leaves their networks. Financial services, healthcare, and defense contractors operate under strict data residency rules that make cloud AI assistants a compliance liability. Local models eliminate both problems simultaneously: the API bill drops to zero, and proprietary code never touches an external server. The AI code assistant market hit $3–3.5 billion in 2025 (Gartner), which means the tooling to run serious models locally has matured — Ollama now supports 100+ models, and quantized 7B parameter models run comfortably on a 16GB RAM MacBook M-series chip. ...

The right answer depends entirely on your scale: Ollama is the fastest path from zero to running a local LLM (2 minutes, zero config), LM Studio is the best option if you’re on integrated graphics or want a GUI, and vLLM is the only serious choice once you need to serve more than one user concurrently — it delivers up to 16x higher throughput than Ollama under load. Why Developers Are Moving from Cloud APIs to Local Inference Local LLM deployment is not a niche experiment anymore. The market is projected to grow 42% in 2026 as developers calculate the real cost of API calls at scale and start weighing data privacy risks. When you’re running a coding assistant for a team of 30 engineers, sending every keystroke completion to OpenAI adds up fast — both financially and contractually. The shift is also driven by model quality: open-weight models like Llama 3.3, Mistral, and Devstral have closed most of the capability gap with commercial frontier models for code-heavy workloads. In 2025–2026, Ollama adoption alone grew 300% by developer survey data (JetBrains AI Pulse), making it the default entry point for local inference. But adoption data also shows a clear pattern: 80% of developers start with Ollama for experimentation, then hit a scaling wall when they try to share the instance with their team. That’s the moment the “which stack” question becomes urgent. ...

Choosing between vLLM and Ollama for serving LLMs in production is not a matter of which tool is “better” — it is a matter of which tool solves the problem you actually have. vLLM serves 18.4 million Docker pulls and 2.79 million weekly PyPI downloads from teams running high-throughput inference APIs on GPU clusters. Ollama serves 126 million Docker pulls and 169,569 GitHub stars from developers running models locally on laptops and workstations. They overlap in capability but diverge sharply in architecture, performance characteristics, and production fitness. This guide compares them directly — with benchmarks, cost data, and a decision framework — so you can pick the right tool for your actual workload, not the one with more GitHub stars. ...

You do not need to pay for cloud AI APIs anymore. Ollama and LM Studio let you run powerful language models entirely on your own hardware — for free, with full privacy, and with zero per-request cost. Ollama is the developer’s tool: a CLI that deploys models in one command and serves them via an OpenAI-compatible API. LM Studio is the explorer’s tool: a polished desktop app with a built-in model browser, chat interface, and visual performance monitoring. Both use llama.cpp under the hood, so raw inference speed is nearly identical. Most power users in 2026 run both — LM Studio for experimenting with new models, Ollama for production integration. ...
