Changelog

Four current open-weight chat models are live on /v1/chat/completions with streaming, tool calling and JSON mode. GPT-OSS 120B is the replacement Groq recommends for Llama 3.3 70B; Groq-style ids are accepted as aliases.

Added /v1/audio/speech (Kokoro 82M with 54 voices, Orpheus 3B) and /v1/audio/transcriptions (Whisper Large v3, Parakeet TDT 0.6B v3). Both follow the OpenAI request shape; speech is billed per character, transcription per audio minute.

The gateway now serves /v1/chat/completions, /v1/models and /v1/voices, and accepts /openai/v1/… so Groq-style base URLs work with only the host changed. Streaming responses include usage in the final chunk.

Two new browser playgrounds: generate speech with any voice and download the audio, or transcribe an upload / microphone recording with timestamps. Every playground shows the exact cURL request.

All rates are on one page: chat per 1M tokens, speech per 1M characters, transcription per audio minute. Llama 3.3 70B was repriced to $1.35 / 1M to reflect upstream cost.

Started a vendor-neutral error reference with entries for Groq 429 rate_limit_exceeded, the llama-3.3-70b-versatile retirement, and the paused Developer-tier upgrade. Each entry states whether waiting helps and lists every fix, including the ones that do not involve us.

The gateway now requires an API key on every request, checks balance before forwarding, and records per-request usage. Previously the legacy endpoint accepted unauthenticated requests.
