The lab behind Claude. Known for careful reasoning, huge context windows, and the most “human” writing of any frontier model.
Anthropic builds Claude, a family of frontier models consistently praised for long-form writing, careful reasoning, and code review. Its API is the second-most-integrated behind OpenAI, and its 200K+ token context windows make it the default for document-heavy workflows.
Who it's for: Writers, analysts, and engineers who need long context, nuanced output, and strong code review. Enterprises that prioritize interpretability and safety.
Opus-class models lead many coding and agentic benchmarks while staying readable and careful.
Paste entire codebases, books, or contract sets — Claude holds the thread across huge inputs.
Render code, docs, and SVGs in a side panel you can iterate on without leaving the chat.
Call Claude directly or through AWS Bedrock and Google Vertex for regulated workloads.
For writing, analysis, and careful coding, Claude is the tool to beat in 2026. Claude Pro ($20) plus the API covers most power users — keep ChatGPT around for image and voice.
