## Summary

Cloudflare released **Clef** and **Clef-flash**, two decision models designed to route AI agents’ actions without human oversight. Unlike traditional language models, these models assign probabilities to predefined options—such as ticket routing or escalation—enabling automated responses. Clef-flash responds in **39 milliseconds**, while Clef takes **209 milliseconds**, both faster than TypeSafe AI’s **Jev**, which Cloudflare claims has a latency of **524 milliseconds** on average. Both models run on Cloudflare’s infrastructure and support text and images, unlike Jev, which is text-only. They also feature a **64,000-token context window**, double Jev’s capacity, and outperform it on Cloudflare’s **Jev Decision Index** benchmarks across 43 tests.

Cloudflare built Clef and Clef-flash using **Qwen3.8-27B** and **Qwen3.5-9B** models, respectively, and trained them with synthetic data and a variant of **Reinforcement Learning for Calibrated Decisions (RLCD)**, the same method TypeSafe used for Jev. The company is rolling out a **reinforcement learning service** to let customers fine-tune the models for their own use cases, starting with engineer-assisted deployment before a self-service platform arrives. Clef is available on **Hugging Face under Apache-2.0** and will be used internally for abuse reporting, support routing, and bot classification. Cloudflare’s move follows OpenAI’s **Decisions API**, also launched in late September, which similarly routes AI actions based on predefined options.

## Key points

- Cloudflare’s Clef models route AI agent actions in **39–209ms**, faster than TypeSafe’s Jev at **524ms**
- Both support text and images, with a **64K-token window**, double Jev’s capacity and outperform it on benchmarks
- Cloudflare offers fine-tuning via a reinforcement learning service, with self-service coming later

## Why it matters

Faster, multimodal decision models could accelerate AI automation in customer support, threat detection, and workflows, reducing latency and enabling real-time routing without human intervention.
