Cheapest code API: DeepSeek V4 Flash at ₹9.07 / 1M tokens

DeepSeek V4 Flash is the fastest, cheapest way to generate code in India. ₹9.07 per 1M input tokens, ₹18.14 per 1M output tokens — about one-tenth Claude Sonnet's cost, and it holds its own on competitive programming and systems code. Billed in rupees on a monthly GST invoice, no international card needed.

Code benchmarks

On typical coding workloads — function generation, debugging, refactoring:

Model	Coding strength	Input ₹/M	Speed	Notes
DeepSeek V4 Flash	Strong	9.07	<1s	Best ₹-per-token value
Qwen3 235B	Strong	9.07	2–3s	Vision included
Llama 4 Maverick	Good	20.16	3–5s	Open-weight
Claude Sonnet	Very strong	201.6	2–3s	Most reliable on complex refactors
GPT-4o	Very strong	252	<2s	Fastest frontier option

DeepSeek is competitive with Claude on straight logic; Qwen adds vision (read a screenshot or diagram alongside the code); Claude tends to win on multi-file, complex refactoring where it can hold more context in mind.

Monthly cost for a coding assistant

For an IDE assistant doing ~2M input + 1M output tokens/month (a few hundred completions a day):

Model	₹/month
DeepSeek V4 Flash	₹36
Qwen3 235B	₹74
Llama 4 Maverick	₹121
Claude Sonnet	₹1,411
GPT-4o	₹1,512

At this volume, DeepSeek V4 Flash costs less per month than a single cup of chai a week — the price difference only starts to matter once you're running it across a whole engineering team.

How to code with DeepSeek V4 Flash

from openai import OpenAI

client = OpenAI(
  base_url="https://api.unoblox.ai/v1",
  api_key="ub-gw-…"
)

response = client.chat.completions.create(
  model="deepseek-ai/deepseek-v4-flash",
  messages=[{
    "role": "user",
    "content": "Write a function to find the longest substring without repeating characters"
  }]
)

print(response.choices[0].message.content)

3-step setup for coding assistants

1. Generate an API key. unoblox.ai → Playground → Keys.
2. Pick your tool: Use DeepSeek with Cline, Cursor, Continue.dev, or LangChain (all OpenAI-compatible).
3. Set base URL: https://api.unoblox.ai/v1. One key works for all models.

Frequently asked questions

Q: How accurate is DeepSeek V4 Flash at code? Strong on standard coding benchmarks and in day-to-day use — great for production code, debugging, and refactoring. Edge cases like unusual async patterns or security-sensitive code are still worth a manual review, as with any model.

Q: Can I use it in Cursor or Cline? Yes. Paste your unoblox API key; set base URL to https://api.unoblox.ai/v1; pick deepseek-ai/deepseek-v4-flash.

Q: What's the context window? 64K tokens. Upload a 20KB codebase; get refactored code back in one request.

Q: Does it support streaming? Yes. Set stream=True in OpenAI SDK; text appears token-by-token in your IDE.

Q: Should I use V4 Flash or V4.1 Flash? V4 Flash (₹9.07) is faster, cheaper. V4.1 Flash (₹20.16) is 5% stronger on reasoning. Use V4 for most tasks; switch if hitting edge cases.
