🚨 GPT-5.6 Rumors Are Getting Wild
• 1.5M token context window
• Faster agent execution & tool use
• Major improvements in SVG/UI generation
• Lower hallucination rates on long-context tasks
• Stronger coding performance than GPT-5.5 Pro
OpenAI is in a harder spot than people realize.
If GPT-5.6 is weak, Anthropic owns the intelligence narrative.
If GPT-5.6 is strong, it enters the Fable/Mythos zone:
benchmarks stop being the bottleneck.
permission becomes the bottleneck.
This is the real model war now.
The important part is not just that Fable/Mythos got pulled.
It is the precedent that frontier capability can become a deployment permission problem overnight.
Introducing FrontierCode: a coding eval that raises the bar for difficulty & quality. Each task took 40+ hrs of work by leading open-source maintainers.
Models write sloppy code that works but isn’t maintainable. Our eval is first to measure: would you actually merge this code?
