RLM (Recursive Language Model) is a plug-and-play Python inference library that lets you run models that call themselves recursively within configurable sandboxed execution environments. Rather than a fixed inference pipeline, RLM exposes the recursive call graph as a first-class primitive — models can iterate, self-correct, and re-invoke themselves across different environments without special orchestration glue. The library was first published in December 2025 and has accumulated 3,498 stars on GitHub. It targets researchers and engineers exploring architectures where the model itself controls how many times it reasons before committing to an output — a capability becoming central to advanced reasoning systems but usually buried in proprietary labs. Why it matters: most open-source inference tools treat the model as a stateless function. RLM bets that the next wave of reasoning breakthroughs comes from architectures where inference depth is dynamic and model-controlled. Early adopters are using it to reproduce recursive reasoning experiments without access to frontier-model APIs.

T3 Code is a minimal web-based GUI for running AI coding agents, built by the Ping.gg team behind the popular T3 Stack. Available via `npx t3` or as a native desktop app for Windows, macOS, and Linux, it provides a clean browser-native interface to coding agents like Codex and Claude without requiring IDE plugins or extensions. The project targets developers who prefer working with AI coding assistants outside of VS Code or Cursor — whether in a standalone terminal environment, on a remote server, or simply because they want a lighter-weight experience. The v0.0.20 release shipped on April 17, 2026, and it's been gaining rapid traction given the T3 community's existing audience of TypeScript developers. As coding agent fatigue with heavyweight IDE extensions grows, browser-native interfaces represent a pragmatic alternative. T3 Code keeps the footprint small and the UX opinionated, which is the team's signature strength.
Reviewer scorecard
“Finally a clean abstraction for recursive inference without building the scaffolding yourself. The sandbox configurability means you can experiment with different execution environments without rewriting your harness each time. For researchers reproducing chain-of-recursive-thought papers, this cuts setup time dramatically.”
“Running `npx t3` and getting a browser UI for Codex and Claude is genuinely convenient for remote dev environments and headless servers where you can't run a full IDE. The T3 team has a track record of clean, opinionated tooling. This fits that pattern.”
“3,500 stars is respectable but the library is still at v0.x with no production deployments publicly documented. Recursive self-calling can blow up token costs exponentially if you're not careful about termination conditions. Until there's clearer documentation on guardrails and cost controls, treat this as a research toy, not production infra.”
“Coding agent GUIs are becoming a commodity — Cursor, Claude Code, GitHub Copilot, and a dozen others already fight for this space. Being 'just a web UI' without deep IDE integration means you're missing context, file tree navigation, and inline diffs that make agents actually useful for large codebases.”
“Recursive inference is one of the key unlock mechanisms for models that self-improve their reasoning at test time. RLM democratizes this capability at a moment when OpenAI and Anthropic are building proprietary versions internally. The researcher who masters this abstraction today has a significant head start.”
“Browser-native agent interfaces are the right long-term architecture. IDE plugins are a transitional form — the eventual paradigm is agents accessed through lightweight universal interfaces that aren't tied to any specific editor. T3 Code is early to that thesis.”
“For creative applications — iterative story refinement, self-critiquing copy — recursive inference is genuinely useful and RLM makes it accessible. The open sandbox model means you can wire it to any content generation pipeline without vendor lock-in.”
“For technical content creators who demo AI coding tools, a clean browser UI is far more screencast-friendly than a full IDE. T3 Code's minimalist aesthetic makes for excellent video and stream material.”
