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.

SuperHQ is a macOS desktop app that runs Claude Code, OpenAI Codex, and other AI coding agents inside isolated Debian microVMs. Your project mounts at /workspace as a read-only overlay — all agent changes stay sandboxed until you review and approve them through a unified diff panel. Launched April 4, 2026 in early alpha, built in Rust with GPUI, it supports VM snapshots for instant rollback and secret proxying so your .env never reaches the agent. It's essentially a safety layer for the increasingly autonomous AI coding workflow.
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.”
“This is the missing piece for anyone running Claude Code on real projects. The overlay filesystem means you can let the agent go wild without fear — review, apply, or revert. The VM snapshot feature alone is worth the price of admission (which is currently free). Rough edges in alpha, but the architecture is right.”
“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.”
“Launched 8 days ago, 37 stars, and their own README says 'largely vibe-coded' and 'not ready for production use.' That's three separate red flags in one sentence. The concept is solid but this is a weekend project dressed up as infrastructure. Come back in six months when it's actually been tested.”
“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.”
“Sandboxed agent execution is not optional — it's where the whole industry is heading. SuperHQ is early but it's defining the architecture that enterprise AI coding tooling will converge on. The microVM approach mirrors what Anthropic's own managed agents use. Get familiar with this pattern now.”
“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.”
“The diff review panel is a genuinely well-designed UX for an alpha product — it makes the agent's changes legible before you commit. Still very rough on onboarding and the documentation is sparse. But for anyone who's ever had an AI agent stomp over their codebase, this is cathartic.”
