[00:00:00]82.7%.

[00:00:01]That's GPT 5.5 on terminal bench 2.0.

[00:00:05]The benchmark for autonomous terminal operation. Every other Frontier model trails by more than 13 points. Claude Mythos preview 69.4%.

[00:00:13]Gemini 3.1 Pro 68.5%.

[00:00:17]Open AI didn't patch a model they retrained from scratch. First time since GPT 4.5. Here's the thread connecting everything they shipped on April 23rd.

[00:00:29]The architecture is agentic. It runs software end to end without handholding.

[00:00:34]The context window hit 1 million tokens.

[00:00:38]And on MRCR, the long context memory benchmark performance doubled 36% to 74%. Now the catch. Price doubled $5 per million input tokens, $30 per million output. That's the GPT 4.5 stack repriced. But here's the builder math.

[00:00:57]GPT 5.5 uses 40% fewer tokens on most tasks. Run the numbers. The real cost increase is around 20%. And if it passes 25% more of your agentic tasks on the first try, it breaks even. The hallucination rate is still the highest among Frontier models. That's the asterisk. Best autonomous terminal model alive. Higher sticker price, lower actual cost. Hallucination problem unsolved.
