Anthropic has made 1 million token context windows generally available for its Claude Opus 4.6 and Sonnet 4.6 models without charging a long-context premium. This contrasts with competitors like OpenAI and Google, which charge extra for prompts exceeding certain token thresholds. The move represents a significant pricing advantage for handling large documents and complex tasks.
Background
Large language models typically have context window limits that determine how much text they can process in a single prompt. Many providers charge premium rates for extended context windows beyond certain thresholds.
