Steps to reproduce

  1. Make a workflow with image capabilities and a LLM node with vision capabilities
  2. Ensure LLM node is set to High Quality vision
  3. Publish and run app
  4. Provide image file to the workflow
  5. The request sent to the LLM has the quality parameter set to low, even tough it is defined to be high
    Tested across models and providers - issue seems to be persistent

✔️ Expected Behavior

  • Defined vision quality settings are reflected in the call the to the LLM endpoint

❌ Actual Behavior
