ChatGPT vs Claude
The short answer
Claude leads on raw capability — its strongest model, Claude Fable 5.1, posts the higher combined coding and reasoning score in this comparison. ChatGPT is the cheaper way in: GPT-6 Luna blends to $0.22 per million tokens, which is what matters once you are running volume rather than evaluating. ChatGPT offers the wider context window at 1.05M tokens. Most teams end up using both — one for the hard problems, one for everything else.

OpenAI's consumer product and the most widely used AI assistant. Strongest on multimodal breadth — voice, image generation, browsing, and agent tooling all ship in the same subscription. The API line-up spans a full frontier-to-budget ladder on one 1.05M-token context.
