Adopt with guardrails

Why: o1 proved test-time reasoning compute is a real, industry-validated paradigm — adopted within months by DeepSeek R1, Gemini, Claude, and OpenAI's own o3/GPT-5.x — so the underlying approach merits confidence, but the specific o1-preview/o1-mini artifacts are now shut down and independent peer-reviewed evidence shows the paradigm still has sharp reasoning-reliability limits, so guardrails belong on whichever current reasoning model replaces it.
Next: Do not target the retired o1-preview/o1-mini endpoints; standardize on current-generation reasoning models (o3/o4-mini, GPT-5.x, Gemini 3.x thinking, or the Claude extended thinking already used across the ecosystem), budgeting for their higher latency/cost, and treat hidden chain-of-thought plus accuracy-collapse-on-complexity as monitored risks rather than assumed-solved.
