Clef-omni adds audio and video input, Clef-flash is now cheaper, and Clef is faster

@cf/cloudflare/clef-omni is now available on Workers AI. Clef-omni is a decision model that takes audio (WAV or MP3) and video (MP4 or WebM) input alongside text and images. It joins Clef and Clef-flash in the Clef family of open-weight decision models.

Introducing Clef: Cloudflare's first open-source decision models, now on Workers AI

Meet @cf/cloudflare/clef and @cf/cloudflare/clef-flash, the first models trained by the Cloudflare Workers AI team, available on Workers AI today.

Reject busy synchronous inference requests

The rejectIfBusy option lets synchronous Workers AI inference requests fail when capacity is unavailable. Use it when your application should not wait in a capacity queue.

Z.ai GLM-5.3 now available on Workers AI

@cf/zai-org/glm-5.3 is now available on Workers AI. It is Z.ai's flagship agentic coding model, built for long-running, tool-driven development workflows rather than single-turn chat.

Workers AI and AI Gateway unify model access and billing

Workers AI and AI Gateway now provide a unified path for accessing models and managing inference traffic.

Select models now require the Workers Paid plan

We are limiting Workers Free plan access to a few resource-intensive models so we can prioritize capacity for the broader Workers AI user base. This helps everyone get a more reliable inference experience, with fewer 429 and 3040 (Out of Capacity) errors.

Plain text output for Markdown Conversion

The Markdown Conversion service now supports a new output conversion option that controls the format of the converted content.

Workers AI toMarkdown and AI Search now supports GIF and BMP image conversion

Partnering with Moondream to bring their latest model @cf/moondream/moondream3.1-9B-A2B to Workers AI.

Introducing GLM-5.2 on Workers AI

We are excited to announce GLM-5.2 on Workers AI, Z.ai's flagship agentic coding model.

Moonshot AI Kimi K2.7 Code now available on Workers AI

@cf/moonshotai/kimi-k2.7-code is now available on Workers AI. Kimi K2.7 Code is a code-optimized variant of the Kimi K2 family, built on a Mixture-of-Experts architecture with 1T total parameters and 32B active per token.

Planned model deprecations on Workers AI

We are refreshing the Workers AI model catalog to make room for newer releases. Please update your apps to remove references to the models listed below before the deprecation date.

Moonshot AI Kimi K2.6 now available on Workers AI

@cf/moonshotai/kimi-k2.6 is now available on Workers AI, in partnership with Moonshot AI for Day 0 support.

Google Gemma 4 26B A4B now available on Workers AI

We are partnering with Google to bring @cf/google/gemma-4-26b-a4b-it to Workers AI. Gemma 4 26B A4B is a Mixture-of-Experts (MoE) model built from Gemini 3 research, with 26B total parameters and only 4B active per forward pass.

Moonshot AI Kimi K2.5 now available on Workers AI

Workers AI is officially in the big models game. @cf/moonshotai/kimi-k2.5 is the first frontier-scale open-source model on our AI inference platform — a large model with a full 256k context window, multi-turn tool calling, vision inputs, and structured outputs.

NVIDIA Nemotron 3 Super now available on Workers AI

We're excited to partner with NVIDIA to bring @cf/nvidia/nemotron-3-120b-a12b to Workers AI. NVIDIA Nemotron 3 Super is a Mixture-of-Experts (MoE) model with a hybrid Mamba-transformer architecture, 120B total parameters, and 12B active parameters per forward pass.
