Hi there,

We gave a try to ai-inference action with the openai/gpt-5-nano model but got this error:

Run actions/ai-inference@v2
  
Using legacy prompt format
Running simple inference without tools
Error: simpleInference: chatCompletion failed: Error: 400 Unsupported parameter: 'max_tokens' is not supported with this model. Use 'max_completion_tokens' instead.

Best,
