temperature = 0

output_config = { " effort " : " high " }

The correct configuration is temperature = 0 and output_config = { " effort " : " high " }. The requirement is to reduce small wording variations that are breaking automated validation. In chat completion requests, temperature controls sampling randomness. Microsoft’s Azure OpenAI reference states that temperature ranges between 0 and 2, and that higher values make output more random while lower values make output more focused and deterministic. Therefore, the most stable setting from the available choices is 0, because it minimizes randomness and improves repeatability for validation-sensitive response patterns.

The solution must also maximize reasoning quality. The code already enables thinking with thinking={ " type " : " enabled " }, so the remaining reasoning-quality control is the effort setting. Microsoft Foundry model guidance states that the effort parameter controls the quality/cost tradeoff and supports low, medium, and high effort levels. Selecting " high " maximizes reasoning quality among the available options.

Using temperature values of 1 or 2 would increase variability and make validation mismatches more likely. Selecting low or medium effort would not meet the requirement to maximize reasoning quality.
