Anthropic’s Claude Sonnet 4 now supports 1M token context window

The OpenAI rival announced a 5x ~increase~ to the context window for its Sonnet 4 model, which refers to the amount of text or data an AI model can process in one go. Sonnet 4 can now handle around 2,500 pages of text (which could translate to hundreds of documents) or entire code bases with 75,000 lines of code or more.
