What is Cocoon?
Cocoon is a secure, open-source and decentralised platform for running AI models. Telegram built it, and uses it to power its own AI features without handing conversations to a third-party provider.
The problem it exists to solve
Adding AI features to a messenger normally means sending user text to an external model provider. That provider then sees the content, and the privacy promise of the messenger only extends as far as its supplier's. For a service whose entire proposition is that conversations stay private, that is not an acceptable trade.
What Cocoon does differently
- Decentralised. Processing is distributed rather than concentrated in one company's data centre.
- Open source. The implementation can be inspected instead of taken on trust.
- Designed so the data stays inaccessible. The point is that whoever runs the computation cannot read what they are computing on.
- Not Telegram-only. It is built as a platform other privacy-conscious applications can use.
What it means for you
The practical effect is that using an AI feature inside Telegram does not quietly forward your conversation to an outside company. The architecture is what makes the difference, rather than a contractual promise from a supplier.
This does not change how Secret Chats work. Those remain end-to-end encrypted between the two devices, and nothing about them is processed anywhere else.
