Implementing OpenAI ChatGPT Streaming with Elixir
The content focuses on the implementation of real-time streaming of OpenAI's ChatGPT responses using Elixir. The author describes the problem of creating an interactive experience similar to OpenAI Chat UI and proposes a solution using Server Sent Events with Elixir. Initially, he introduces the `Req` library, a high-level HTTP client developed by Wojtek Mach, and explains its advantages and integration with the lower-level `Finch` library. To tackle the challenge, a function named `gpt_stream` is created, which uses the `Req.post!` function to initiate a stream and process the data using a callback function. The post provides detailed code examples and outlines the steps for setting up the streaming API call, handling the server sent events, and appending data. The author concludes with an example of calling the `gpt_stream` function and leaves further data processing, such as broadcasting to a `pid` or using `PubSub`, to the reader.
