Anthropic
Claude models through your own Anthropic API key and the official SDK, for text and tool-calling chat across the current tiers, such as Sonnet and Haiku. Requests go straight from your machine to Anthropic and you pay Anthropic's own rates, with no platform in between.

Anthropic's Fable model for the most demanding reasoning and long-horizon agentic work, improving on Fable 5.1 in coding, reasoning and vision at a lower price, with always-on adaptive thinking and a 1M-token context window.
Anthropic's fastest model, built for high-volume, latency-sensitive work such as classification, extraction, routing and subagent tasks, with vision, tool use and a 1M-token context window.
Anthropic's Sonnet-class model for everyday coding and agentic work, a direct upgrade to Sonnet 5 with vision, tool use and a 1M-token context window.
Anthropic's Fable model for the most demanding reasoning and long-horizon agentic work, with always-on adaptive thinking, vision, and a 1M-token context window.
Anthropic's Opus model for long-running agentic coding and knowledge work, with always-on adaptive thinking, vision, and a 1M-token context window.
Anthropic's most agentic Sonnet — frontier-level coding and tool use at Sonnet speed and price, with vision.
Anthropic's Claude 5-family model for the most demanding reasoning, coding, and agentic work — with vision and a 128K output budget.
Anthropic's most capable model — frontier reasoning, coding, and agentic tool use with vision.
Anthropic's fast, cost-efficient model with strong reasoning, coding, and tool use at low latency.
