Model name inconsistency: the CSV shows "Deepseek V3.2" and "DeepSeek V3.2 Thinking" with different capitalizations. The product should use consistent casing for the "DeepSeek" brand name throughout.

[Copilot]

The default values for temperature, frequency_penalty, and presence_penalty are applied when the agent properties are None. However, if these fields are defined as optional in the Agent model but have default values, this explicit None checking may be redundant. Additionally, the hardcoded defaults (0.7, 0.0, 0.0) might differ from the model's schema defaults. Consider defining these defaults in one central location to avoid inconsistency.

The name 'agent_generator_router' is exported by all but is not defined.
