Ollama

The de facto runtime for running open-weights LLMs locally, now with a paid cloud tier for bigger models.

Freemium· Free local; Pro $20/mo; Max $100/moCodingMulti-model (Llama, Qwen, Gemma, DeepSeek, Mistral, Phi, etc.)

Best for

Pick Ollama if you want one command to run open-weights LLMs on your own hardware with a clean API that any client can hit.

Skip if

Skip it if you need high-throughput production inference at scale or specifically want frontier closed models like GPT-5 or Claude.

Ollama is the simplest way to download, run, and serve open-weights large language models on your own machine. A single CLI pulls quantized GGUF builds of Llama, Qwen, Gemma, DeepSeek, Mistral, Phi and dozens of others, then exposes them over a local OpenAI-compatible HTTP API so any client (Open WebUI, Continue, LangChain, Claude Code, custom apps) can talk to them without code changes. Mac, Linux and Windows are all first-class.

The tool is open source (MIT) and free for local use, which is how most people meet it. Ollama now also sells a hosted tier for models too big for a laptop: Pro at $20/mo runs up to 3 cloud models concurrently, Max at $100/mo bumps that to 10, with US/EU/Singapore regions and a 'your data is never trained on' promise. The hybrid story (develop locally, burst to cloud with the same API) is the differentiator versus pure-local llama.cpp or pure-cloud Together/Fireworks.

The ecosystem is huge: every desktop LLM client, IDE plugin, and agent framework worth mentioning has an Ollama adapter, and the model library is curated and quantization-tagged so 'ollama run qwen2.5:14b' Just Works. Limitations: it's a wrapper over llama.cpp under the hood, so cutting-edge inference engines (vLLM, SGLang) are faster for serving, and the cloud tier is newer and less battle-tested than Together/Groq.

Editor's take

Ollama is the package manager for local LLMs and has basically won that category. The new paid cloud tier is a smart hedge for users whose laptops can't fit a 70B model, though serious production teams will still reach for vLLM or a hosted inference API. For everyone else, it's the obvious default.

Pros

✅ Easiest path to running open-weights LLMs locally on Mac/Linux/Windows
✅ OpenAI-compatible API means existing tooling works out of the box
✅ Huge curated model library with sensible quantization defaults
✅ Same API for local and cloud lets you scale without rewriting code
✅ Open source (MIT) with a massive integration ecosystem

Cons

⚠️ Underlying llama.cpp engine is slower than vLLM/SGLang for production serving
⚠️ Cloud tier is newer than competitors like Together or Fireworks
⚠️ Configuration of GPU offload and context length can be finicky
