What you can build

Run a small evaluation in the languages and tool-calling formats you need, and review outputs for factual errors and unsafe content before deployment.

Limitations

The model card says the model has no moderation mechanisms and may produce factually incorrect, biased, or offensive output. Its tool-call arguments are not schema-enforced by the documented parser and should be treated as untrusted input.
