Chat parameters

When creating a new chat, you may not only select the model, but also customize the following:

  • system instruction prompt
  • tools used. See Tools for more information on how to make tools available.
  • chat parameters (such as context length, seed, temperature etc) passed to the model. For a list of all supported parameters refer to the Ollama documentation.
  • Ouput format/structured output. In the format field you can use Ollama's Structured Output specifying the full format as a JSON schema. Leaving the field empty (default) will return the output as text.

You can also "edit" an existing chat to change the system prompt, parameters, tools or format. Note, that the model cannot be changed once the chat has started.
