Stop guessing which model to wire in. Fire the same prompt at a handful at once — India-resident open-weight models next to frontier ones, even Sangamconsensus — and read the answers, latency and cost together, on the exact/v1/chat/completions wire format you'll ship with.
1 · Your API key— stays in your browser (localStorage), sent only to api.bharatrouter.com
No key yet? Create one — trial keys work (200 req/day, free). Open-weight / self-hosted models cost ₹0; frontier models bill your wallet (or your BYOK key).
2 · Models to compare— add a few; each answers the same prompt independently
3 · Prompt
The same thing, from your code
Comparison fans the one prompt out to each model in parallel — the same call, just with a different model. Found the winner? Wire that id in, or hand the whole panel toSangam and let it return one reconciled answer.
Every model has a personality — one is terse, one reasons better in Hindi, one is faster, one is a tenth of the price. The only honest way to pick is to put them next to each other on your prompt. BharatRouter lets you do that across the whole catalog at once: sovereign open-weight models you can self-host, frontier models on your key or ours, andSangam consensus — all on one wire format, so swapping the winner in is a one-line change. Latency is wall-clock from your browser; cost is the real ₹ each call would bill at catalog rates (open-weight / self-hosted routes are ₹0).
