I've been unable to reproduce this error. I've tried every combination with the following variations in the AI Assistant:
Opus 4.6, 4.5, and 4.1
Temperature set to 0 or 1
Top K set to 0 or 1

Upping this to Major. Can replicate it in AI API Explorer, where all configuration values are always sent.

This affects haiku as well, so Claude Haiku 4.5.

This also occurs for other providers that use Claude such as ai_provider_amazeeio and ai_provider_litellm.

It is happening on ai_api_explorer - if "top_p" and/or "temperature" are not set, they still get sent as null values.

I have updated regex to inlude all claude models.

Raised an issue in AI module (#3580249) to prevent other providers, using affected models.

I have tested with claude and amazee providers.
