GPT-5.4 tops Matt Maher's planning benchmark
OpenAI's GPT-5.4 Thinking model achieved a record 95% score on Matt Maher's planning benchmark, outperforming all current models in complex requirement preservation. Optimized for long-horizon agentic workflows, the model features native computer-use capabilities and a 1M token context window.
// ANALYSIS
GPT-5.4 is the first model to truly "get" long-horizon planning, but the real story is the discovery that execution context significantly boosts planning quality.
- –Achieved 95% on the Maher benchmark, setting a new bar for PRD requirement preservation.
- –Features "interruptible thinking," allowing developers to steer model logic mid-generation without a full restart.
- –Native computer-use success rate of 75.0% marks the first time an AI has officially beaten the human baseline in OSWorld.
- –The "Something Stranger" finding suggests that tool mode (execution vs. planning) is as impactful as the model's raw IQ.
- –Full MCP support and 1M context window make it the clear choice for complex, tool-heavy agentic systems.
