This demo shows how to build a telegram chatbot for GPT4. The application is written in Rust and deployed as a Wasm serverless function on the flows.network platform. It utilizes the following SaaS or PaaS platforms.

• Telegram API to interact with bots on the telegram platform.
• OpenAI's Assistant API to interact with GPT4 in threads.
• The Catalyst Dapr-as-a-Service API to manage application states.

The Catalyst service provides a key-value store itself. But more interestingly, it can use almost any cloud-based storage service as its KV store backend, providing a standard API for multi-cloud applications.
