How this price is scoped: Cloudflare's own Workers AI pricing page lists @cf/cloudflare/clef-flash at $0.038 per M input tokens (3,455 neurons per M input tokens) and prints no output rate. Cloudflare's 2026-10-09 changelog announced the cut to this price and the smaller 24K-token hosted window that came with it; LiteLLM's public price table still shows the older $0.09 launch rate. Clef models do not charge for output tokens, because they return a decision with a probability for each allowed answer rather than generated text, so the $0 output here is Cloudflare's own published rate, not a missing number. Images and video are converted to input tokens and billed at the same input rate.
Price receipt
No confirmed receipt. We hold dated captures of Cloudflare's pricing page, but none of them tied Clef-flash to the price above on that page, so we do not claim this number is sourced. Check the provider's page directly before relying on it.
Overview
The fast, small member of Cloudflare's Clef family: a 9B multimodal decision model that reads a state (text, JSON, images or video) and typed questions and returns a probability for every allowed answer, not generated text. Cloudflare measured a 38.8 ms median latency at launch, about 13x faster than TypeSafe's Jev. On 2026-10-09 Cloudflare cut its price to $0.038 per 1M input tokens and shrank the hosted context window from 64K to 24K tokens to offer that price. No output charge.
