Clef-omni (9 October 2026) adds audio and video input. Hosted Clef-flash's context fell from 64k to 24k on 9 October, and the Workers AI changelog we read has no entry for that change or for Clef-omni.\n\n**RightNow System Zero.** A well-documented decision API with an OpenAPI file, idempotent retries, a detailed error catalogue, streaming over WebSocket and published per-unit prices with USD 5 of starting credit. Standard context is 38,000 tokens; the 64k, 128k and 1M bands are held and video is a preview. The latency and benchmark figures are RightNow's own, and several of its pages disagree.\n\n## Before you call either\n\n### Clef\n\n1. Send `model` in the body as `clef`, `clef-flash` or `clef-omni`, matching the model in the URL. The input schema requires it\n2. Ask every independent question about one state in one call. Up to 64 are allowed\n3. Try `clef-flash` first for text-only triage under 24k tokens. It costs $0.038 per million input tokens against $0.24 for Clef\n4. Send Clef-omni audio and video as base64 data URIs in `audio` and `videos`. Remote URLs are not accepted\n5. Media and questions count towards the context window. If they exceed it, the request fails. Otherwise text state is truncated to fit\n6. Read the internal code on a 429. 3036 means the day's 10,000 free neurons are spent, 3040 means capacity, so retry later\n7. Treat an answer about user-supplied text, images, audio or video as a judgement that hostile input can steer. Cloudflare publishes no guidance on it\n\n### RightNow System Zero\n\n1. Send audio only as inline 16,000 Hz WAV. The FLAC, MP3, OGG and MP4 audio named on the blog are refused with media_unsupported.\n2. Keep state under 38,000 tokens. Long-context requests return 404 long_context_not_available, which never succeeds on retry.\n3. Reuse the same Idempotency-Key and body on retries, and stop when error.retryable or x-should-retry is false.\n4. Check every entry in answers even on HTTP 200, since one question can be refused while the others are answered.\n5. Treat probabilities as uncalibrated while calibrated is false, and pin system-zero-2.0.0 when answers must not move with the alias.\n\n## Tutorials\n\n- [Flag an outage report with Cloudflare Clef](https://www.anchorterminal.com/tutorials/cloudflare-clef/), for Clef\n\n## Questions\n\n### Which is better for AI agents, Clef or RightNow System Zero?\n\nRightNow System Zero and Clef score within a point of each other on agent readiness, 66.8 (B) and 66 (B).
