Clef is a 27B multimodal model developed by Cloudflare that transforms state data and schemas of typed questions into structured decisions. By accepting text, JSON, images, or video as input, it returns a probability for every allowed option of each question in a single forward pass, entirely eliminating free-form text generation and output parsing. The model is post-trained from Qwen/Qwen3.8-27B and features a joint schema head that routes evidence to each question and scores all options simultaneously. It is fully compatible with Jev and SystemOne APIs, making it well-suited for deterministic, structured decision-making tasks.
- Supports `choice`, `score`, and `noul` (true/false) question types
- A smaller, faster variant called Clef-Flash is also available
- Achieves strong benchmark results, particularly on BFCL (98.5%), ToolRet (69.2), and API-Bank (91.9%)
- Significantly faster than comparable models, with a median latency of 209.3 ms
- Released under the Apache-2.0 license

Amanda Caswell writes about Cloudflare's new Monetization Gateway, which allows domain owners to charge AI agents for accessing APIs, websites, and datasets using the x402 protocol. This system enables payments in USDC on the Base blockchain via HTTP requests, but it introduces significant challenges for developers regarding spending control, variable pricing models, and the need for robust observability to track transaction history during retries.
- The gateway supports price ranges from $0.001 to $100 per request.
- It features two payment schemes: 'exact' for fixed prices and 'upto' for variable rates.
- Developers can implement "Virtual Wallets" with allowances, allowlists, and maximum transaction sizes to manage agent spending.
- Cloudflare plans to make paid services discoverable so agents can find tools during an active workflow. author »

Matt Carey and Aron Carroll write about @cloudflare/computer, an open-source library designed to provide a scalable runtime for agentic systems. By offering a durable virtual filesystem backed by SQLite alongside diverse execution environments—including lightweight isolates and full Linux containers—the package allows models to perform tasks ranging from simple file manipulation to complex code execution. This architecture aims to solve the scalability issues inherent in providing dedicated containerized compute for every concurrent agent, enabling massive horizontal scaling through Cloudflare's isolate-based infrastructure.
- The virtual filesystem is backed by SQLite and can be populated via cloud storage or source control
- Isolates use just-bash to translate shell commands into JavaScript runs within dynamic workers
- Container runtimes employ Filesystem in Userspace (FUSE) mounts to sync files between the container and the workspace

Botasaurus is an all-in-one web scraping framework designed to help developers build undetectable scrapers that can bypass sophisticated bot detection systems like Cloudflare, Datadome, and BrowserScan. It simplifies the development process by providing high-level abstractions for browser automation, humane HTTP requests, and general data tasks. Key features include human-like mouse movements, browser-based fetch requests to significantly reduce proxy costs, and built-in utilities for caching, sitemap processing, and data cleaning.
Main topics:
- Bypassing Cloudflare WAF and Turnstile CAPTCHAs.
- Creating UI-based scrapers for non-technical end-users.
- Converting scrapers into standalone desktop applications.
- Scaling scraping infrastructure using Docker and Kubernetes.
- Cost-efficient proxy management and bandwidth reduction strategies.

On May 5, 2026, DENIC published incorrect DNSSEC signatures for the .de TLD during a key rollover, causing validating resolvers globally to return SERVFAIL errors. This article details how Cloudflare's 1.1.1.1 resolver responded using "serve stale" mechanisms and implemented an emergency override equivalent to a Negative Trust Anchor (NTA) to restore connectivity by treating the zone as unsigned. The post also covers mitigations for origin resolution and identifies improvements needed for Extended DNS Error (EDE) reporting.

- How RFC 8767 "serve stale" cushions the impact of upstream outages
- Using Negative Trust Anchors to bypass broken cryptographic validation

This post demonstrates how to use Cloudflare's Browser Rendering to easily crawl entire websites, even those with complex JavaScript. It simplifies web crawling by rendering pages with a single API call, bypassing the need for headless browsers and enabling efficient data extraction for tasks like SEO monitoring and content archiving.
This article discusses the latest developments in AI agents, including the launch of Perplexity Computer, the shift from 'vibe coding' to 'agentic engineering', the standardization efforts around AI agents, and OpenAI's new deal with the Pentagon after Anthropic was dropped.

An open source project called Scrapling is gaining traction with AI agent users who want their bots to scrape sites without permission, and is being used to bypass anti-bot systems like Cloudflare Turnstile. Cloudflare is actively working to counter these efforts.
Cloudflare converts HTML to Markdown on the fly when an AI agent requests it via the `Accept: text/markdown` header.
Cloudflare launched Markdown for Agents, converting HTML pages to markdown automatically when AI crawlers request it through content negotiation. This feature is available in beta at no additional cost for eligible paid plans.
