# Models and cost per reply

> How Koshra lets you pick a model per bot, switch mid-chat, keep a backup chain and see the model, cost and time of every reply.

You choose the model for each bot, and every reply tells you what it cost.

## A model per bot

Each bot has its own model. Leads can run a larger model and desks a smaller one.

## Switch mid-chat

Change the model from the picker in the chat composer. The next reply uses the new model.

## Backup chain

Behind each model sits a backup chain. If a provider is down or out of credit, the next model in the chain answers.

## Usage estimates

Per-bot model selection, mid-chat switching and fallback configuration are implemented. A reply can show a model, a cost estimate and time when the provider reports them. That is not a fresh acceptance of every provider.

## Free open models

Choose supported model providers or bring an API key. Some providers offer free-tier models; availability is not guaranteed. Provider charges, quotas and data policies apply.

## Not locked to one model

Bring your own key for OpenAI, Anthropic, Google, OpenRouter, MiniMax or any OpenAI-compatible endpoint. Keys are stored encrypted and shown masked. Fallback chains can end on free models.

## Sign in with your existing AI plan (coming soon)

Using a Claude or ChatGPT plan you already pay for, instead of an API key.
