## Updated Pricing for Language Models

Model APIs

Language model prices have changed. `sarvam-105b` and `sarvam-105b-conversations` now cost ₹15 input, ₹5 cached input, and ₹60 output per 1M tokens. `gemma4` is now ₹35 / ₹10 / ₹90. `glm5.3` cached input and output drop to ₹20 and ₹390, and input stays at ₹126. `deepseekv4.1-flash` is now ₹25 / ₹0.5 / ₹105. See [Pricing](/api/getting-started/pricing) for the full table.

## Session Affinity for Chat Completion V2

Model APIs

`POST /v2/chat/completions` now accepts an optional `x-session-affinity` header. Send the same session ID on every turn of a conversation, and later turns can reuse cached prompt context for lower latency. Session IDs are scoped to your API subscription, and requests without the header work as before. See [Session affinity](/api/api-guides-tutorials/chat-completion/overview#session-affinity-for-multi-turn-conversations).
