DeepSeek V4.1 Flash API in India

DeepSeek V4.1 Flash is the mid tier of DeepSeek's Flash line, and it's callable from India through unoblox on the same ₹-billed, OpenAI-compatible endpoint as every other model in the catalogue — one key, streaming and tool calling included, settled on a single monthly GST invoice.

Where V4.1 Flash sits in the DeepSeek line

unoblox carries three DeepSeek models side by side, and they're priced far enough apart that picking the right one matters:

Model	Input (₹ / 1M tokens)	Output (₹ / 1M tokens)
DeepSeek V4 Flash	9.07	18.14
DeepSeek V4.1 Flash	20.16	60.48
DeepSeek V3.2	26.21	38.30

V4.1 Flash sits between the two on input cost but has a noticeably higher output price than V4 Flash, which matters most for tasks that generate long responses — worth testing generation-heavy prompts against both Flash variants before choosing.

Calling DeepSeek V4.1 Flash from the unoblox endpoint

curl https://api.unoblox.ai/v1/chat/completions \
  -H "Authorization: Bearer ub-gw-xxxxxxxxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "deepseek-ai/deepseek-v4.1-flash",
    "messages": [{"role": "user", "content": "Draft release notes from this list of bug fixes."}]
  }'

Because the request shape matches every other model on unoblox, comparing V4.1 Flash against V4 Flash or V3.2 on the same prompt is a matter of changing one field and re-running the call.

When V4.1 Flash is the right pick

• You've tried DeepSeek V4 Flash and need noticeably better output quality, and the roughly 2x input, 3x output price difference is worth it for your workload.
• You want a middle ground between V4 Flash's low cost and V3.2's pricing and behaviour.
• You're generating short-to-medium responses where the output-token price difference against V4 Flash stays manageable — for very long generations, that gap compounds quickly, so it's worth checking against actual output-token counts from a real prompt.
