Free AI API in India

Free AI API in India — Qwen3.8-27B, ₹0 forever

unoblox runs a genuinely free AI API tier: Qwen3.8-27B at ₹0, no payment method needed to sign up, no card, no trial countdown. It's meant for prototyping, testing, and low-traffic production apps that don't need frontier-model reasoning.

The free tier, plainly

Feature	Qwen3.8-27B (Free)
Cost	₹0 / month
Payment method required	No
Rate limit	Fair-use limit of 10 requests/min per workspace
Monthly cap	None
Support	Community + docs
Context window	262,144 tokens

If you need more throughput than the fair-use limit allows, you simply move the same code to a paid model — nothing breaks, nothing double-bills.

What the free tier is actually good for

• Simple chat and support bots — FAQ-style Q&A under moderate volume.
• Classification — sentiment, ticket tagging, intent routing.
• Templated generation — short-form copy, meta descriptions, boilerplate replies.
• Extraction — pulling structured fields out of emails, invoices, forms.
• Summarization — meeting notes, short articles, ticket threads.

For these narrow, well-defined tasks, a free model like this is usually accurate enough that upgrading wouldn't change the outcome — it would just add cost.

When to graduate off free

There's no forced upgrade, but three signals usually mean it's time:

1. Output quality visibly degrades on your specific task — move to Qwen3 235B-A22B (₹9.11 / ₹55.67 per 1M tokens) first; it's a low-cost step up.
2. You need long-context reasoning — Llama 4 Scout (₹10.12 / ₹30.36) is another low-cost upgrade.
3. You hit the fair-use rate limit consistently — at that point the free tier has already done its job (validating the product); paying a few hundred rupees a month is a rounding error against what you're building.

The API key and endpoint don't change when you upgrade — only the model field does.

Sample code

from openai import OpenAI

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

response = client.chat.completions.create(
    model="qwen/qwen3.8-27b",
    messages=[
        {"role": "user", "content": "What is machine learning in one sentence?"}
    ]
)

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

Fair use, not surveillance

unoblox doesn't monitor content for competitive reasons — it rate-limits to prevent abuse (synthetic content farms, key reselling, scripted hammering). A normal app, even a fairly busy one, rarely brushes up against the 10 requests/minute fair-use limit.

Frequently asked questions

Is the free tier really free, or a time-limited trial? It's not a trial. Qwen3.8-27B stays at ₹0 with no sunset date. The only limit is the per-minute fair-use rate limit.

Do I need to enter payment details to start? No. Sign up with email and password, generate a key, and start calling the API immediately.

How does free-tier quality compare to paid models? For narrow tasks (classification, templated generation, short summarization) it's usually close enough that most teams don't notice a difference. For open-ended reasoning or long-form analysis, a paid model does meaningfully better.

What happens when I hit the rate limit? You get a 429 response. Add basic client-side backoff, or move to a paid key tier if you're consistently bumping into it.

Can I run real production traffic on the free tier? Yes, within the fair-use rate limit — plenty of low-traffic features (internal tools, early-stage products) stay on it indefinitely.

Is there a limit on how many free keys I can create? Keys are scoped to your account, not unlimited per person — create what your project structure actually needs (e.g., one per environment).
