> [Fast version] The Meta Llama 3.1 collection of multilingual large language models (LLMs) is a collection of pretrained and instruction tuned generative models.

**Creator**: meta  
**Category**: text  
**Context**: 128K tokens  
**Status**: Disabled (since 2026-07-26) — no longer routable or listed; kept for history/usage reference.  
**Reason**: The model is gone from Cloudflare's live account catalogue and the binding returns HTTP 404 (model does not exist). It was this model's only upstream, so it was disabled rather than the route pruned.
