Striking Back: OpenAI Releases GPT-5.5 with Focus on Coding and AI Agents

The race among frontier models forgives no delays. On April 24, 2026, OpenAI officially announced `GPT-5.5`, a minor but critically important update to its flagship.

The release is clearly intended as a response to the recent launch of Claude Opus 4.7 by Anthropic. OpenAI claims a radical increase in quality regarding coding, research, tool use, and solving complex scientific problems. The updated logic is available to paid ChatGPT subscribers and in the Codex developer environment. The industry has definitively shifted its focus from creative text generation to Agentic AI: the winner will be the one whose model can more reliably perform multi-step autonomous tasks without hallucinations.
