Model Notes

When min_tokens is set, the model may generate EOS (End of Sequence) tokens which may cause parser failures. Use at your own risk.
This model may call tools that aren't directly specified due to it's training. Monitor for non-approved tools and reprompt with "you're hallucinating a tool call" to help the model self-correct and stick to provided tools.
For this model, our API maps the "system" role to developer-level instructions in our prompt hierarchy. See our OpenAI Compatibility guide for more details.
