Claude Opus 5.5 API in India

In Indian rupees, the currency your card is charged in, with the published US dollar rate beside each.

For scale: 1,000 requests of about 3,000 tokens in and 1,000 out cost ₹3,230.08 — a long prompt and a page of answer each. Every rate is published and stays the same from one request to the next. See every model.

Prices are our published US dollar rates converted at ₹98.00 to the dollar, our rate for October — the same rate your card is charged.

Opus 5.5 replaced Opus 5 in September 2026 and is the model Anthropic tells most people to start with. Anthropic puts it at about 40% cheaper than its predecessor on typical work and more than 30% faster at writing its answer. On professional knowledge work it scored higher than Fable 5.1 in Anthropic’s own GDPval-AA test — 1846 against 1735 — and it reached 66.4% on Terminal-Bench 4.0.

Thinking is always on, at medium effort by default. For long coding sessions, reviewing a large codebase and business analysis it is the safe high-end choice; Fable 5.1 is only worth the extra on problems Opus cannot crack.

• Long coding sessions and reviewing large codebases.
• Financial analysis, reports and other professional knowledge work.
• Automating multi-step business workflows.
• A dependable default when you are not sure which model to use.

• Thinking cannot be switched off, so even a simple question carries some reasoning time and cost.
• Anthropic itself cautions that benchmark leads have become a weak guide to real differences. Compare it on your own tasks.
• Cybersecurity and biology requests may be refused by Anthropic’s safety filters.
