Claude Opus Pricing in India (₹ per Token)

Claude Opus is Anthropic's flagship reasoning model, and on unoblox it is billed the way Indian teams actually budget: in rupees, per token, on a single monthly GST invoice. No international card, no separate overseas top-up, and no spreadsheet translating an international invoice back into rupees at month-end. This page lays out exactly what Claude Opus costs on unoblox and how to start calling it today.

What Claude Opus costs on unoblox

unoblox prices every model per 1 million tokens, split between input (what you send) and output (what the model generates). Output tokens cost more everywhere because generation is the expensive part of inference.

Model	Input (₹ / 1M tokens)	Output (₹ / 1M tokens)
Claude Opus	₹504	₹2,520
Claude Sonnet (for comparison)	₹201.6	₹1,008

To put that in everyday terms: a single call with 1,000 input tokens and 500 output tokens on Claude Opus costs roughly ₹0.50 (input) + ₹1.26 (output) ≈ ₹1.76. Run that same shape of call a thousand times in a month and you are looking at roughly ₹1,760 — a number you can put straight into a budget line, with no lookup step in between.

Which Claude Opus model id to call

unoblox lists more than one generation of Opus on the catalog — anthropic/claude-opus-5 is the current flagship, alongside anthropic/claude-opus-4-5 and anthropic/claude-opus-4-8 for teams standardised on a specific prior release. All three share the same OpenAI-compatible request shape. Check the exact per-model rate on its own page, for example /models/anthropic/claude-opus-5, before committing a production workload — rates are shown live there.

Calling it from code you already have

Point your existing OpenAI SDK (or any HTTP client) at the unoblox base URL and swap the model name and key. Nothing else about your request format changes — streaming, tool calls and JSON mode all work as-is.

Opus vs Sonnet: which one should you pay for

• Choose Opus when a task is genuinely hard — multi-step reasoning, long documents, code that has to be right the first time — and the higher per-token rate is worth it for fewer retries.
• Choose Sonnet for the bulk of everyday traffic — chat, summarisation, classification — where Sonnet's ₹201.6 / ₹1,008 rate does the job at roughly a quarter of Opus's cost.
• Mix both behind one key: route the easy 80% of requests to Sonnet and escalate only the hard 20% to Opus. Because both sit behind the same endpoint and the same rupee invoice, switching model names in code is the only change needed.

Frequently asked questions

Is Claude Opus pricing on unoblox the same as calling Anthropic directly? unoblox publishes its own ₹ rate per model, shown on each model's page. It is billed in rupees on a monthly GST invoice from an Indian entity rather than through an overseas billing account, which is the main practical difference for an India-based team.

Does using Claude Opus through unoblox mean my data stays in India? No — Claude Opus is Anthropic's model and inference happens on Anthropic's infrastructure. What unoblox adds is rupee billing, a GST invoice, and one endpoint for Opus alongside every other model you use. Only unoblox's own small hosted models run on India infrastructure.

Can I get an input tax credit on Claude Opus usage? Yes — because the invoice is a standard monthly GST invoice from an Indian entity, it is claimable as input tax credit the same way any other GST-billed business expense would be.

Is there a cheaper way to get similar quality to Opus? Claude Sonnet, at roughly a quarter of Opus's rate, is the usual first thing to try. For open-weight alternatives, models like Qwen3 235B-A22B are priced even lower — see /models for the full live list.

Do I need a separate account with Anthropic to use Claude Opus on unoblox? No. One unoblox key (ub-gw-...) authenticates against every model on the catalog, including Claude Opus — there is no separate Anthropic account or billing relationship to set up.

How often does unoblox invoice for Claude Opus usage? Usage across every model, including Claude Opus, rolls up into a single monthly GST invoice — you are not billed per model or per provider separately.
