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.

Together AI Dedicated Fine-Tuning Clusters

Reserved H100/H200 GPU clusters for enterprise fine-tuning at scale

Entry

Together AI's dedicated GPU cluster reservations give enterprises reserved access to H100 and H200 nodes for large-scale fine-tuning workloads, with persistent storage and experiment tracking included. Fine-tuned models deploy directly to Together's inference API, eliminating the export-and-redeploy cycle. It targets ML teams whose fine-tuning jobs are too large, too frequent, or too sensitive for shared serverless compute.

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.

The primitive here is clear: reserved GPU capacity with a tight loop from training run to deployed endpoint, no intermediate artifact wrangling. The DX bet is that teams want vertical integration — track experiments, tune, deploy — all without leaving Together's surface, and that's the right call for the target workload. The moment of truth is whether the API surface for job submission and monitoring is actually clean or whether it's a web console with a JSON export bolted on; the blog post gestures at this but doesn't show me the SDK. This is not something you replicate with a cron job — H200 cluster orchestration plus experiment tracking plus inference deployment is genuine infrastructure — but I want to see the Python client before I fully commit.

Skeptic

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.

Category is dedicated ML compute for fine-tuning, and the direct competitors are CoreWeave reserved instances, Lambda Labs, and — increasingly — the hyperscalers' own fine-tuning managed services like Azure AI Studio and Vertex AI. Where Together wins is the closed loop: the same company running your fine-tune also serves the inference, which means the handoff latency and model format translation problem just disappears. The scenario where this breaks is at true enterprise scale — if a team needs multi-region redundancy, SOC 2 Type II audit trails for every training run, or on-prem data residency, Together's answer is almost certainly 'contact sales and wait.' What kills this in 12 months: OpenAI or Anthropic ships fine-tuning on their frontier models with comparable scale and the 'we're model-agnostic' pitch loses its edge.

Futurist
80/100 · ship

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.

80/100 · ship

The thesis here is specific and falsifiable: by 2027, the dominant enterprise AI stack is not a foundation model API call but a continuously fine-tuned proprietary model that lives close to inference — and whoever owns that fine-tune-to-serve loop owns the relationship. That dependency requires that fine-tuning remains a differentiated activity rather than getting commoditized away by better base models or synthetic data techniques, which is a real risk but a 3-year runway is plausible. The second-order effect that isn't obvious: this accelerates the consolidation of ML infrastructure spend away from multi-vendor setups toward single-vendor vertical stacks, which means the companies that don't win this race don't just lose revenue, they lose observability into what enterprises are actually training. Together is on-time to this trend — CoreWeave got there first on raw compute, but the training-to-inference integration layer is still genuinely open.

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.
