Description

Claude Sonnet 4.6 represents a comprehensive upgrade to Anthropic’s Sonnet model line, delivering expanded capabilities across coding, reasoning, computer interaction, and professional knowledge tasks. With a beta 1M token context window, the model can process massive datasets such as full repositories, extended legal agreements, or multi-document research projects in a single request. Developers report improved reliability, better instruction adherence, and fewer hallucinations, making long working sessions smoother and more predictable. Early users preferred Sonnet 4.6 over its predecessor in the majority of tests and often selected it over Opus 4.5 for practical coding work. The model’s computer-use skills have advanced significantly, enabling it to navigate spreadsheets, complete web forms, and manage multi-tab workflows with near human-level competence in many cases. Benchmark evaluations show consistent performance gains across reasoning, coding, and long-horizon planning tasks. In competitive simulations like Vending-Bench Arena, Sonnet 4.6 demonstrated strategic capacity-building and profit optimization over time. On the developer platform, it supports adaptive and extended thinking modes, context compaction, and improved tool integration for greater efficiency. Claude’s API tools now automatically execute filtering and code-processing steps to enhance search and token optimization. Sonnet 4.6 is available across Claude.ai, Cowork, Claude Code, the API, and major cloud providers at the same starting price as Sonnet 4.5.

Description

Jurassic-1 offers two model sizes, with the Jumbo variant being the largest at 178 billion parameters, representing the pinnacle of complexity in language models released for developers. Currently, AI21 Studio is in an open beta phase, inviting users to register and begin exploring Jurassic-1 through an accessible API and an interactive web platform. At AI21 Labs, our goal is to revolutionize how people engage with reading and writing by integrating machines as cognitive collaborators, a vision that requires collective effort to realize. Our exploration of language models dates back to what we refer to as our Mesozoic Era (2017 😉). Building upon this foundational research, Jurassic-1 marks the inaugural series of models we are now offering for broad public application. As we move forward, we are excited to see how users will leverage these advancements in their own creative processes.
