GitHub - not-pizza/tysm

Dec 27, 2024 - github.com
The article introduces "tysm," a strongly-typed Rust client for OpenAI's ChatGPT API that ensures type-safe responses using Structured Outputs. It highlights the key features of the library, including type-safe API responses, a concise interface, and automatic local caching of API responses. The setup process involves obtaining an API key from OpenAI, creating a `.env` file for environment variables, and adding the necessary dependencies to a Rust project. The library supports custom API endpoints and offers feature flags, such as disabling the default `dotenv` feature for environment variable loading.

The backstory explains the motivation behind creating "tysm," emphasizing the author's desire to simplify the process of interacting with ChatGPT in Rust due to the lack of robust existing solutions. The library is designed for ease of use, with built-in caching and dotenv support, and is intended to be a straightforward, single-file solution. The article also addresses a common issue related to the `schemars` dependency and provides guidance on resolving it by using an in-development version from GitHub. The project is licensed under the MIT License.

Key takeaways:

  • tysm is a strongly-typed Rust client for OpenAI's ChatGPT API that ensures type-safe responses using Structured Outputs.
  • The library supports automatic caching of API responses, storing the last 1024 responses to optimize performance and reduce costs.
  • Custom API endpoints can be used by modifying the client's URL, allowing flexibility in API usage.
  • The project is licensed under the MIT License and includes built-in dotenv support for easy environment variable management.
