DeepSeek V4 Flash API in India

DeepSeek V4 Flash is the speed-and-cost tier of the V4 family — built for high-volume inference rather than deep reasoning. On unoblox it's priced at ₹9.07 per million input tokens and ₹18.14 per million output tokens, billed monthly in rupees.

What Flash is optimized for

Flash trades some reasoning depth for throughput and price. That trade-off makes sense for chatbots, search ranking, classification, and any pipeline running thousands of requests an hour, where V3.2's deeper (and pricier) reasoning would be wasted.

Pricing in context

Model	Input (₹/1M)	Output (₹/1M)	Fit
DeepSeek V4 Flash	₹9.07	₹18.14	High-volume chat, RAG, classification
DeepSeek V4.1 Flash	₹20.16	₹60.48	A step up in quality, still fast
DeepSeek V3.2	₹26.21	₹38.30	Deep reasoning, proofs, research

V4 Flash costs roughly 45% of V4.1 Flash's input price and about 30% of its output price. As a worked example: 50 million input tokens plus 10 million output tokens in a month costs about ₹635 on V4 Flash versus about ₹1,613 on V4.1 Flash — roughly ₹978 saved by staying on Flash for workloads that don't need the extra quality.

How to switch to Flash

1. Get a key → sign up at https://unoblox.ai/sign-in (a couple of minutes).
2. Swap the model string → deepseek-ai/deepseek-v4-flash.
3. Ship and watch spend → per-request cost in rupees shows up in your dashboard immediately.

const OpenAI = require('openai');
const client = new OpenAI({
    apiKey: process.env.UNOBLOX_KEY,
    baseURL: 'https://api.unoblox.ai/v1',
});
const msg = await client.chat.completions.create({
    model: 'deepseek-ai/deepseek-v4-flash',
    messages: [{ role: 'user', content: 'Classify this support ticket...' }],
});

Why India teams pick Flash

• Low cost per token — ₹9.07 per million input tokens is one of the cheaper rates on the catalog.
• India-resident billing — a GST invoice every month, input-tax credit claimable, nothing to reconcile against a foreign statement.
• Scale without fixed fees — pay for what you use; no monthly minimum.
• One key for everything — move to V3.2, GPT, or Claude from the same integration when a request needs more depth.

Frequently asked questions

Is Flash good enough for production chatbots? Yes — it's built for exactly that. The trade-off is lighter reasoning depth, which rarely matters for chat, classification, or search.

Can I A/B test Flash against another model? Easily — changing the model string is a one-line edit, so you can run both in production and compare quality before committing.

Do you offer custom rates at high volume? Published rates are on /models; teams spending significantly more than average can talk to us about custom terms.

Can I use Flash for embeddings or images? Flash handles text and multi-turn chat. For vector search, call the native /v1/embeddings endpoint, which is priced separately.

Does a long prompt cost more per token? No. Input tokens are billed at the same per-token rate regardless of prompt length — there's no separate long-context surcharge.
