On April, 23 2026, OpenAI released GPT-5.5. OpenAI announced that GPT-5.5 “excels at writing and debugging code, researching online, analyzing data, creating documents and spreadsheets, operating software, and moving across tools until a task is finished. Instead of carefully managing every step, you can give GPT‑5.5 a messy, multi-part task and trust it to plan, use tools, check its work, navigate through ambiguity, and keep going.  The gains are especially strong in agentic coding, computer use, knowledge work, and early scientific research—areas where progress depends on reasoning across context and taking action over time. ”

OpenAI shared the following benchmarks comparing GPT 5.5 to several other popular AI models in their announcement:

For Coding specific evlauations they also shared their SWE-Bench Pro (public), Terminal Bench 2.0 and Expert-SWE (Interal) Benchmarks:

I can’t wait to test and see how GPT-5.5  improves my own AI assisted game development!
