GPT-5.4 Thinking Mode unlocks 94% reasoning with 7 real-world prompts
OpenAI's GPT-5.4 introduces Extended Thinking, a toggle that lets the model simulate and self-correct before answering, reporting a 94% reasoning score on ARC-AGI-1 and demonstrating seven real-world prompts (real-time code auditing, tax/legal analysis, hard logic puzzles, patent prior art checks, financial anomaly detection, world-building continuity, and cyber network audits) that reveal stronger reasoning than standard AI. The article notes Thinking mode can be slower and more expensive, and that some prompts may require reframing to bypass safety gates. It is sponsored content.
