Sjq

Sjq is a command-line tool that parses OpenAI-compatible chat completion streams and displays token deltas.

Sjq is a command-line tool designed to process OpenAI-compatible chat completion streams and Server-Sent Events. It reads the stream as it arrives, strips repetitive envelope data, and keeps only what each event adds, reducing token overhead. It supports chat completions and the Responses API, handling reasoning tokens, tool calls, and metadata changes. Users can pipe streams into sjq, run curl commands through it, or replay saved stream files. It provides timing metrics including time to first token, speed, and connection timings.
