Super easy to use tool to launch self hosted llm, even for other AI tools.

Image generation is still not available at this time.

No idea about alternatives, and sincerely I don't feel I need one

Recently I a long flight and having ollama (with llama2) locally really helped me prototype some quick changes to our product without having to rely on spotty plane wifi.

Very easy and powerful to run and customize local LLMs, and to integrate (Langchain or LlamaIndex).

That's Cool and useful! I can have my repository of models and run them from my terminal

Easy to run multiple AI models locally without worrying about privacy issues.

Ollama is what I reach for when I want a model running locally in under a minute, and that matters more than people admit. The one-line pulls and the OpenAI-compatible endpoint mean I can drop it under existing code with almost no changes. Where it still bites me: concurrent requests get serialized in ways that aren't obvious until you load-test, and juggling VRAM across a few models gets fiddly. For local dev and prototyping though, nothing else is this frictionless.

Every feature in AI Observability was tested against local models running on Ollama before it touched a hosted API. It's the fastest way to generate real LLM traffic on a laptop, and it kept our dev loop tight. Also the reason we care so much about self-hosting: if you run your models yourself, you should be able to run your observability yourself too.

Offline summaries had to be a real option, not a footnote. Ollama is the least-friction way for a user to run a local model on their Mac — no account, no API key, nothing leaves the machine. I didn't want the privacy story to depend on Apple Intelligence being available.
