About Claude Instant

Fast text generation with large context

Claude Instant (claude-instant-1.2) is a large language model developed by Anthropic, designed to prioritize rapid response generation while maintaining solid language understanding. It supports a 100,000 token context window, allowing it to process and respond to long documents or extended conversations in a single session. The model is now deprecated, meaning Anthropic no longer actively maintains or recommends it for new projects.

Claude Instant was built for use cases where response speed and efficiency matter, such as conversational AI applications, real-time language processing, and high-throughput workflows. Its maximum response size is 4,096 tokens per output. Developers who previously relied on Claude Instant are encouraged to migrate to current Anthropic model offerings, as this version is no longer receiving updates.
