Recursive Language Models (RLMs): From MIT’s Blueprint to Prime Intellect’s RLMEnv for Long Horizon LLM Agents
Recursive Language Models give a practical recipe for ultra long context agents, and Prime Intellect shows how to run them in production. The MIT RLM paper treats the entire prompt as a Python REPL variable that the LLM can query, decompose and process via recursive sub model calls, which lets GPT 5 and Qwen3 Coder handle 10M plus token inputs with higher accuracy and similar or lower cost than standard long context scaffolds. Prime Intellect extends this blueprint with RLMEnv and its verifiers based Environments Hub, wiring RLM style agents into INTELLECT 3 and other models for DeepDive, math and OOLONG style workloads.

How Cloudflare’s tokio-quiche Makes QUIC and HTTP/3 a First Class Citizen in Rust Backends
Cloudflare has open sourced tokio quiche, an async Rust library that combines its quiche QUIC or HTTP 3 implementation with the Tokio runtime so developers can build high performance QUIC services without writing custom UDP or event loop code. The crate is already proven in production inside Apple iCloud Private Relay, Oxy based HTTP 3 proxies and WARP’s MASQUE client, where it handles millions of HTTP 3 requests per second using an actor based architecture, an ApplicationOverQuic abstraction and an HTTP 3 specific H3Driver that together provide a clean foundation for Rust teams adopting modern QUIC and HTTP 3 transports.
