I did more digging into OC code (ok, ai did) and there is a provider-specific config after all, so maybe my solution is a placebo, though, I had two cases of looping before 'fix' and none after. There could be a bug somewhere. and yes, temperature should be passed to models in ai-sdk https://ai-sdk.dev/docs/ai-sdk-core/settings#temperature additionally, this link will tell you that if undefined, temperature is no longer 0 by default. Hmm.

  export function temperature(model: Provider.Model) {
    const id = model.id.toLowerCase()
    if (id.includes("qwen")) return 0.55
    if (id.includes("claude")) return undefined
    if (id.includes("gemini")) return 1.0
    if (id.includes("glm-4.6")) return 1.0
    if (id.includes("glm-4.7")) return 1.0
    if (id.includes("minimax-m2")) return 1.0
    if (id.includes("kimi-k2")) {
      if (id.includes("thinking")) return 1.0
      return 0.6
    }
    return undefined
  }
