Original GitHub issue: https://github.com/ollama/ollama/issues/7661

The large model supports 128k data input, which is equivalent to supporting hundreds of thousands of words. What is the maximum number of words that the ollama URL can support for input? Can you input hundreds of thousands of words.

Yes it can – however, make sure to set the context window with /set parameter num_ctx 128000 or "options": {"num_ctx": 128000}} in the API

What if the prompt I send to ollama exceeds the model context length? What does ollama do?

  1. Reject the request with error code.
  2. Accept all the text, but only the text within context window is actually sent to the model.
  3. Cache the text, and repeatedly send segments to model, while preserving the context.

Which is it？

One more question: is the context length hardcoded 2048 or read from configuration? Or, does it change with the currently loaded model's parameters? If it is not dynamic with models, can I change it with REST API, and can I query it from REST API?

2048 is really limiting. If the context is not dynamic with loaded model, consider this a feature request. :)
