Opus is the right pick where accuracy and depth matter more than raw speed — complex document analysis, research synthesis, or planning systems where extra reasoning time pays for itself.

Existing Anthropic SDK code needs no logic changes — streaming, file attachments, JSON mode, and extended thinking all work the same way through unoblox.

When to choose Opus over Sonnet

Opus wins on: legal document review, research paper synthesis, multi-step reasoning chains, agent planning, code architecture analysis — anywhere the output is high-value and reused, so the extra reasoning depth pays for itself.

Sonnet is better if: you're building user-facing APIs where response time is critical, or running high-volume inference where cost per request is the main lever. See the Claude Sonnet page for its ₹ rates.

Common Opus workloads in India

• Legal and compliance review: long contracts, GST/TDS clause checks, and redlines where a missed nuance is expensive
• Fintech research: summarizing filings, credit memos, or market research where depth beats speed
• Code architecture reviews: reasoning through a large, unfamiliar codebase before a refactor, not just generating boilerplate
• Agent planning: the "planner" step in a multi-agent system, where one good plan saves many cheap-model retries downstream

Enterprise-grade for India

Rupee invoices mean your finance team can book spend to the right cost center immediately. Input tax credit is claimable. There's no currency exposure, no international payment friction, no surprise line items.

Frequently asked questions

What is "extended thinking"? A mode where Claude spends extra computation reasoning step-by-step before it answers — useful for code review and complex analysis. Enable it with thinking: {"type": "enabled", "budget_tokens": 10000}.

Can Opus handle images? Yes — base64 or URL-based images, including PDFs and diagrams, for document extraction or visual reasoning.

Is there a monthly usage cap? No hard cap. You can run as many requests as your account balance supports, and top-ups apply instantly.

How does Opus compare to Sonnet for interactive use? Opus does more reasoning per call, so it suits workflows that can tolerate more processing time; Sonnet is the better default for tight, interactive loops.

Can I use Opus for real-time chat? It works, but its strength is depth rather than raw speed — for latency-sensitive chat, Sonnet is usually the better fit.

Is my data retained by unoblox? Logs are retained for 90–180 days for debugging and are never used for model training. See /guides/ai-api-security-india for details.
