Live coding a streaming ChatGPT proxy with Swift OpenAPI—from scratch!

Join us as we build a ChatGPT client, from scratch, using Swift OpenAPI Generator. We’ll take advantage of Swift OpenAPI’s pluggable HTTP transports to reuse the same generated client to make upstream calls from a Linux server, providing end-to-end streaming, backed by async sequences, without buffering upstream responses.

In this session you’ll learn how to:

• Generate a type-safe ChatGPT macOS client and use URLSession OpenAPI transport.
• Stream LLM responses using Server Sent Events (SSE).
• Bootstrap a Linux proxy server using the Vapor OpenAPI transport.
• Use the same generated ChatGPT client within the proxy by switching to the AsyncHTTPClient transport.
• Efficiently transform responses from SSE to JSON Lines, maintaining end-to-end streaming.
