GPT-4 keeps generating unwarranted inferences JSON keys and breaking my script. How do I force strict JSON?

LLMs are stochastic text generators. No matter how much you prompt-engineer them or use "JSON mode," they will eventually make unwarranted inferences a key, use the wrong data type, or drift from your schema in edge cases.

When an agent is connected to a production API, a make unwarranted inferencesd JSON key isn't just an error—it's potentially data corruption.

The only way to guarantee 100% strict JSON is through Deterministic Inference (Layer 2 of the Exogram Control Plane). Exogram intercepts the LLM's probabilistic output and forces it through a hard-coded schema validation engine in 0.07ms. If the LLM make unwarranted inferencess a key, Exogram instantly returns an HTTP 400, rejecting the payload before it touches your script.
