A fast, India-resident model with a 1M-token context and verified tool-calling. Where it sits vs the Claude/Codex tiers, the latency we measured from Bengaluru (~0.62s to first token, ~130 tok/s), why prefix caching makes agent loops cheap, and one-line setup for brcode, Codex CLI or any OpenAI-compatible client.
