d1: telegram bot can't read info in the history, only newly sent info, so use database to keep them. pricing

cf worker: so no more offline.(I hope so) pricing

gemini-2.0-flash: free for limited usage and huge context

For openAI or others,use the getGenModel from openai.ts, fill in the keys, it returns Promise<string> so remember to await

The Newest 4000 text messages will be kept, images will be kept for 2 days. May change in the future.

Limitation

This bot will store chat history into my d1 database, so deploy your own bot is recommended. Unless I am in your group.

Only messages sent by user and after the bot join the group can be summarized/query.

Why doesn't my bot see messages from other bots? Bots talking to each other could potentially get stuck in unwelcome loops. To avoid this, we decided that bots will not be able to see messages from other bots regardless of mode.

You can't get older message than bot join.
