Reviewer scorecard
“The Docker of LLMs. Pull a model, run it, use the API. Privacy, no cloud costs, works offline. Essential tool for any developer experimenting with local AI.”
“The most mature AI API with the largest ecosystem. Function calling, JSON mode, and assistants API cover every use case.”
“Local models still lag behind cloud models in quality. But for development, testing, and privacy-sensitive use cases, Ollama is the obvious choice. Free is hard to beat.”
“Reliability has improved significantly. The ecosystem and tooling around OpenAI's API remain unmatched.”
“Local AI is the future for privacy and cost. As models get smaller and hardware gets better, Ollama becomes the default way to run AI. They are building the runtime layer.”
“OpenAI set the standard for AI APIs. The Assistants API and real-time API point toward increasingly capable agent platforms.”
