Data control: where is data processed, who has access?
Quality: how well does the model solve your concrete tasks?
Cost: flat rate and hardware or billing by usage?
Effort: who operates, maintains and secures it?
Dependence: how easy is it to switch later?
Integration: does it fit existing services and workflows?
Fundamental differences
Ollama runs open models locally. This gives control and interchangeability but requires hardware and operations. OpenAI, Anthropic Claude and Google Gemini are cloud services with very capable models and a quick start but require trust in the provider and a review of terms.
There are no blanket rankings
Which model is best depends on the task and keeps changing. We therefore test with your real examples and compare the results instead of recommending a brand. A mix is also common: sensitive tasks locally, general tasks in the cloud.
Check points for cloud services
Which terms apply to your offering, for example on training and retention?
Is there a data processing agreement, and how is processing outside the EU regulated?
How can access, permissions and logs be controlled?
Terms change: check the current state before use.

Frequently asked questions
Which is the best AI model?
That depends on the task and keeps changing. We test with your examples instead of recommending across the board.
Can I mix local and cloud?
Yes. Sensitive data locally and general tasks via cloud services is a common pattern.
Can I switch later?
With a clean connection, yes. We aim for interchangeable interfaces to keep dependence low.
