OpenAI releases ChatGPT 5.5 — more complex “knowledge work” for fewer tokens
Right on the heels of Anthropic’s Claude Opus 4.7, OpenAI has also released the next incremental improvement to its flagship frontier model.
OpenAI says that ChatGPT 5.5 performs better on complex coding and data analysis tasks, and more carefully follows instructions, even when the instructions are vague.
Importantly, this gain in capability does not mean developers and companies have to shell out for more tokens (as is the case with Claude Opus 4.7) — the model uses fewer tokens that ChatGPT 5.4.
OpenAI says the new model has strengthened safeguards to ensure that the model’s strong cybersecurity capabilities aren’t used for malicious attacks.
