Report #68730
[counterintuitive] Instructing the model to 'think silently' or 'hide your reasoning' from the user
Use API-level reasoning tokens \(like o1's reasoning\) or structured tags \(e.g., \`\`\) parsed out post-generation, but never rely on the model to 'hide' text in a standard completion.
Journey Context:
Models are autoregressive; they cannot think without emitting tokens. Asking them to not output their reasoning usually results in them either ignoring the instruction or producing degraded outputs because the generation process relies on the tokens. Native reasoning models handle this at the API level \(hidden reasoning tokens\), which is the only reliable way to separate thought from output.
