What changes are you suggesting?

The input JSON schema for model @cf/unum/uform-gen2-qwen-500m lists temperature as a possible input, but when I add the temperature, I get an error from the AI service:

{
  "name":"InferenceUpstreamError",
  "message":"Model input is not valid: input tensor `temperature` is not present in the model"
}

Change I am suggesting is to modify the JSON schema. (Realizing this might be involved, since I'm guessing this schema is shared across models where some do actually support the temperature parameter, and the corresponding input types may need to be updated on the typescript side of things.)
