Artifacts - Artifacts now in beta: versioned filesystem with Git access

Artifacts is now in private beta. Artifacts is Git-compatible storage built for scale: create tens of millions of repos, fork from any remote, and hand off a URL to any Git client. It provides a versioned filesystem for storing and exchanging file trees across Workers, the REST API, and any Git client, running locally or within an agent. You can read the announcement blog to learn more about what Artifacts does, how it works, and how to create repositories for your agents to use. Artifacts has t

Load Balancing and Scaling LLM Serving

Load balancing for LLMs is fundamentally different from load balancing for traditional services like web servers, APIs, or databases. Prompt caching is the reason. Prompt caching typically cuts input token costs by 50-90% and can reduce Time to First Token (TTFT) latency by up to 80%, but those gains assume your request lands on the replica that already has the relevant prefix cached. Under naive round-robin load balancing across N replicas, that probability is 1/N. The cache hit rate that made
