 # Cydonia
 
-Cydonia is a library based on [candle][candle] for developing modern AI applications in rust.
-
-```rust
-use cydonia::Model;
-
-fn main() {
-    let model = Model::new("gemma2").tag("latest");
-    let response = model.invoke("Hello, world!");
-    println!("{}", response);
-}
-```
-
-We support quantized models only derived from `gemma` and `llama` family.
-
-## TODOs
-
-- [x] Support chat interface ( history prompts )
-- [ ] Function encoder for llama3 tools (static)
-- [ ] Cydonia as service
-  - [ ] RPC support for llama3 tools (remote)
-  - [ ] GraphQL support for llama3 tools (remote)
-- [ ] RAG support
-- [ ] Agent interface
-- [ ] Multi-agent support (single-node)
-- [ ] An application based on the tools
-- [ ] p2p for the decentralized cydonia network (multi-node)
-- [ ] Test gpu
