GPT-5.5 is a total freak

Summary

OpenAI has just launched GPT 5.5, a major performance upgrade specifically designed for complex "agentic" tasks like autonomous coding, deep research, and project management. In real-world tests, the model showed incredible results by building fully functional 3D games, interactive simulations, and even automated business workflows from just a few prompts. While it currently tops global leaderboards for logic and reasoning, you should be aware that it’s twice as expensive as its predecessor and still struggles with high-stakes visual tasks like medical diagnostics. If you're a power user looking to push AI to its absolute limits, this model is currently the most sophisticated tool available, though you'll want to keep an eye out for potential hallucinations.
