RLM FAQs

Question 1

How does RLM process such large contexts?

Accepted Answer

RLM employs a multi-step process: it loads the context externally, inspects its structure, strategically chunks it, performs recursive sub-queries on these chunks, and then aggregates the results, all orchestrated by Claude Code behind the scenes.

Question 2

Does RLM support local LLM inference for cost savings?

Accepted Answer

Absolutely. RLM supports flexible LLM providers, including Anthropic's Claude Haiku and local Ollama instances (e.g., with models like Gemma3). This allows for cost-effective inference, especially beneficial for recursive sub-queries or extensive batch processing.

Question 3

Can I perform deterministic data extraction with RLM?

Accepted Answer

Yes, RLM includes `rlm_exec`, a powerful tool that allows Claude to run sandboxed Python code directly against loaded contexts. This enables deterministic data extraction, filtering with regex, and programmatic analysis without involving the LLM's reasoning for simple tasks.

Question 4

How do users interact with RLM?

Accepted Answer

Users typically interact with RLM indirectly. You ask Claude to analyze large files, and Claude intelligently selects and utilizes RLM tools (like `rlm_auto_analyze`) automatically. RLM then handles the complex context management and analysis workflow transparently.

Question 5

What is RLM and what problem does it solve?

Accepted Answer

RLM (Recursive Language Model) is a tool for Claude Code designed to overcome LLM context window limitations. It enables the analysis of massive contexts (10M+ tokens) by treating them as external variables, preventing them from being fed directly into the prompt.
