Is the intended naming convention here? I notice other model IDs in the codebase use hyphens for versioning (like ). Would be more consistent with the existing pattern, or is there a specific reason to avoid dots that also applies to hyphens?

Could we add a reference to official Fireworks or DeepSeek documentation about v3.1 to verify these specifications? This would help future maintainers understand where these values come from.

Good test coverage for the configuration! Consider also adding a test that verifies the model can be properly instantiated and used in the FireworksHandler's method, similar to the existing tests for other models. This would ensure end-to-end functionality.
