OpenAI has released its new GPT-5.5 model, which is described as more efficient and more intuitive than its predecessor. The company claims that the new model excels at tasks such as writing and editing code, researching online, making spreadsheets and documents, and can use fewer tokens to complete tasks in Codex. The release comes amid a fierce competition between OpenAI and Anthropic, who are also competing in the market for AI coding and enterprise tools.
