Anthropic models on Tokenator
Every Anthropic model available through Tokenator: API ID, context window, usage multiplier and current availability. The key and the base URL stay the same for every model in the catalog — switching models takes one request parameter.
Claude Opus 5 is Anthropic’s flagship model for demanding reasoning, coding, and long-horizon agentic work. It is particularly strong at end-to-end software tasks, code review and bug finding, visual analysis of charts and documents, complex office deliverables, and coordinating parallel subagents. The model maintains strong instruction following and tool use across extended tasks, while remaining effective at lower effort settings for workloads that prioritize latency and token efficiency.
This model is available on a free plan with set usage limits. Claude Opus 5 is Anthropic's flagship model for complex logical reasoning, programming, and long-term agent management. It is particularly effective in complex software development, code review and error detection, document and diagram analysis, complex office tasks, and coordinating multiple concurrent subagents. Claude Opus 5 reliably follows instructions and uses tools efficiently, even in lengthy, multi-step tasks. It is also well-suited for scenarios where low latency and more efficient token usage are essential.
Sonnet 5 is Anthropic's most capable Sonnet-class model, with frontier performance across coding, agents, and professional work.
Sonnet 4.6 is Anthropic's most capable Sonnet-class model yet, with frontier performance across coding, agents, and professional work.
Claude Opus 4.8 is Anthropic's most capable generally available model in the Opus family. It supports text, image, and file inputs with text output, with reasoning support and a 1M-token context window.
Opus 4.6 is Anthropic’s strongest model for coding and long-running professional tasks.
Claude Fable 5.1 improves on Claude Fable 5 across the board, with the biggest gains in agentic coding, long-running agentic workflows, and knowledge work: long code refactors, front-end and visual code generation, and finance and analysis tasks in particular. It also tends to be more concise than Fable 5 in its plans and summaries. We recommend testing it as a direct upgrade wherever you use Fable 5 today, and alongside Opus 5 on reasoning-heavy tasks.
Claude Haiku 4.5 is Anthropic’s fastest and most efficient model, delivering near-frontier intelligence at a fraction of the cost and latency of larger Claude models.
Claude Fable 5 is a Mythos-class model from Anthropic, built for autonomous knowledge work and coding.
Opus 4.7 is the next generation of Anthropic's Opus family, built for long-running, asynchronous agents.
