Claude Opus 5 was Anthropic's flagship before Claude Opus 5.5. It is strong at end-to-end software tasks, code review and bug finding, reading charts and documents, complex office deliverables and coordinating sub-agents working in parallel. It keeps following instructions and using tools well over long tasks, and still performs at lower effort settings when speed and token cost matter.
It accepts text, image and file (PDF) input and returns text, and supports tool calling, structured JSON output and streaming. Reasoning can be switched on when a problem needs more thought and left off when speed matters. Claude Opus 5 is commonly used for end-to-end software tasks, code review, chart and document analysis, office deliverables and multi-agent coordination. Hormouz serves it behind an OpenAI-compatible API: point your base URL at Hormouz, drop in a Hormouz key, and existing OpenAI SDK code runs without changes.
Pricing is usage-based: $5 per million input tokens and $25 per million output tokens. There is no fixed monthly fee, and 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.
