Released on 1 October 2026, with no service record and no entry in the Workers AI changelog we read.\n\n**GLiClass.** An Apache-2.0 classifier that scores a whole label set in one encoder pass on the owner's hardware, with single-label, multi-label, hierarchical and few-shot modes. It returns label scores with no calibration claim, the bundled server has no authentication, and the last three test runs on the main branch, on 24 September 2026, failed.\n\n## Before you call either\n\n### Clef\n\n1. Send `model` as `clef` or `clef-flash` in the body as well as 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. It costs $0.09 per million input tokens against $0.24\n4. Read the internal code on a 429. 3036 means the day's 10,000 free neurons are spent, 3040 means capacity, so retry later\n5. Treat an answer about user-supplied text as a judgement that hostile input can steer. Cloudflare publishes no guidance on it\n\n### GLiClass\n\n1. Pass `--host 127.0.0.1` to `python -m gliclass.serve`, or put the port behind your own gateway. The server checks no credential\n2. On a machine without a GPU add `--device cpu --dtype float32 --num-gpus-per-replica 0`. The default configuration expects CUDA\n3. Send one text a request to `POST /gliclass`. An array in `texts` is cut to its first item without an error\n4. Set `multi_label` to false for one label from a set. The default scores each label independently, so scores do not sum to 1\n5. Keep text plus labels under the pipeline's 1,024-token `max_length`, or use `ZeroShotClassificationWithChunkingPipeline`. Longer input is truncated silently\n\n## Questions\n\n### Which is better for AI agents, Clef or GLiClass?\n\nClef scores 66.1 (B) on agent readiness against GLiClass's 49.9 (D), and leads in 6 of 7 scored categories. GLiClass leads on payments \u0026 pricing.\n\n### Do Clef and GLiClass need an API key?\n\nClef needs an API key. GLiClass needs no key.\n\n### Can an agent call Clef and GLiClass without installing anything?\n\nClef has a hosted endpoint at https://api.cloudflare.com/client/v4/accounts/{account_id}/ai/run/@cf/cloudflare/clef. No hosted endpoint is listed for GLiClass.\n\n### Are Clef and GLiClass open source?\n\nNo open-source release is listed for Clef. GLiClass is open source (Apache-2.0 (library and the model weights we checked)).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/cloudflare-clef-vs-gliclass.json, and with the fewest tokens: https://www.anchorterminal.com/compare/cloudflare-clef-vs-gliclass.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"cloudflare-clef\", \"b\": \"gliclass\"}`.
