OpenAI released GPT-5.5 on April 23, 2026, positioning it as a step toward agentic computing and a unified 'superapp' combining ChatGPT, Codex, and browser capabilities. The company claims the model outperforms GPT-5.4, Google's Gemini 3.1 Pro, and Anthropic's Claude Opus 4.5 across multiple benchmarks.

OpenAI has completed pretraining on a new model codenamed 'Spud,' according to an internal memo from CEO Sam Altman reported by The Information. Altman claims the company expects a 'very strong model' within weeks that can 'really accelerate the economy.' To free compute resources, OpenAI will shut down its Sora video generation app.
