Claude Opus 4.8 is the top-capability tier of the Claude family, aimed at the hardest coding, reasoning and long-horizon agentic work. It accepts text and image input and returns text, supports tool calling for building agents and automations, and works with streaming responses. It also supports extended reasoning, so you can trade extra thinking time for higher accuracy on hard problems. The context window is 1M tokens, which suits long documents, large codebases and multi-turn sessions.
Opus-class models are commonly used for complex software engineering, large-codebase refactors, multi-step debugging, long-running agent pipelines and demanding knowledge work. Hormouz serves it behind an OpenAI-compatible API, so you can point your base URL at Hormouz, drop in a Hormouz key, and run existing OpenAI SDK code without changes.
Pricing is usage-based: $5 per million input tokens and $25 per million output tokens. There is no fixed monthly fee. You pay only for the tokens you use. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
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...
