Overview

Clef-flash is a 9B-parameter multimodal decision model developed by Cloudflare and hosted on the Workers AI platform. It is designed for businesses and developers who need to turn unstructured state data—including text, JSON, images, and video—into structured, deterministic decisions. The model works by taking a state input and a schema of typed questions, returning a probability for every allowed option defined in the schema. As part of the Cloudflare developer platform, it runs natively on a global edge network, allowing for high-performance inference close to users and data.

How it works

  1. Define Decision Schema: Define a schema of typed questions and the allowed options for the decisions the model needs to make.
  2. Provide State Input: Provide the current state of the application or environment as text, JSON, images, or video.
  3. Execute Inference: Call the model through Workers AI using the REST API or Workers Bindings to process the state against the schema.
  4. Receive Structured Decisions: Receive a structured response containing probabilities for every allowed option, enabling deterministic application logic.

FAQ

What is Clef-flash?

Clef-flash is a 9B-parameter multimodal decision model designed for high-speed classification and agentic workflows. It turns unstructured state data into structured decisions based on a schema of typed questions.

What modalities does Clef-flash support?

Clef-flash supports state inputs provided as text, JSON, images, or video. It processes these inputs to return probabilities for allowed options defined in a question schema.

How does Clef-flash compare to the standard Clef model?

Clef-flash is optimized for speed and cost-efficiency. Cloudflare recently lowered Clef-flash pricing and boosted inference speeds for the Clef family by up to 2.0x.

How can I access Clef-flash?

Developers can use Clef-flash through Cloudflare Workers AI. It is accessible via Workers Bindings for serverless applications or through a REST API for external service integration.
