Serve Hindi and Indian-language chat on India-resident models, with Sarvam on your own key.

India-resident routes (Krutrim Cloud) + Sarvam BYOKSovereigntyBeginner8 min

For Indian-language products you want models that were built for Indic text and that stay in India. Open models served on Krutrim Cloud in India cover this on your credit, and Sarvam's Indic models are available on your own Sarvam key — point a system prompt at them and pin residency.

You'll use: India-resident Indic models + data_policy: "india_only". Browse them in the model catalog.

Do it

from openai import OpenAI

client = OpenAI(base_url="https://api.bharatrouter.com/v1", api_key="br-...")

r = client.chat.completions.create(
    model="gemma-4-e4b-it",
    messages=[
        {"role": "system", "content": "Aap ek sahaayak hain. Hamesha Hindi mein jawab dein."},
        {"role": "user", "content": "Maharashtra ki raajdhaani kya hai?"},
    ],
    extra_body={"data_policy": "india_only", "optimize": "price"},
)
print(r.choices[0].message.content)

Picking a model

The first row runs on your BharatRouter credit; Sarvam needs your own key. Add a fallback chain across India-resident routes for resilience without ever leaving India.
