How RLM + Rembr Reduces Costs

🔍
Context Sampling
RLM loads only ~10% of your codebase, using programmatic filtering instead of stuffing full context.
🤖
Subagent Decomposition
Complex queries spawn focused sub-agents that each handle a slice of the problem efficiently.
🧠
Semantic Caching
Rembr stores analysis results. Repeat queries retrieve cached insights instantly.
🔄
Compound Learning
Knowledge accumulates. Month 6 costs less than month 1 because memory keeps growing.

What Is Recursive Language Model?

A smarter way to handle massive contexts without breaking the bank

🔥

The Problem: Context Overload

Traditional AI agents stuff everything into one massive context window:

  • Your entire codebase (100K+ tokens)
  • Documentation and web results (50K+ tokens)
  • Chat history and tool outputs (50K+ tokens)

Result: 200K tokens × $0.01/1K = $2 per request
Performance degrades as context grows (context rot)

🧠

The RLM Solution: Smart Delegation

Instead of loading everything at once, the AI breaks down work and delegates to sub-agents:

1️⃣
DECOMPOSE

Break task into smaller sub-problems

2️⃣
DELEGATE

Spawn fresh sub-agents for each piece

3️⃣
SYNTHESIZE

Combine results into final answer

Example: "Refactor auth system across 50 files"

Main agent: Analyzes structure (5K tokens)
Sub-agents: Each handles 1 file (10 × 3K = 30K tokens)
Total: 35K tokens instead of 200K+ = 80%+ savings

🫐

How Rembr Enables RLM

RLM's power comes from not having to re-analyze everything. That requires infrastructure:

1
Persistent Memory

Store analyzed context once, retrieve instantly. Main agent doesn't re-read 100K tokens every session.

2
Semantic Search

Sub-agents retrieve only relevant memories (500 tokens) instead of full context (100K+ tokens).

3
Shared Context

All sub-agents access the same memory pool. No redundant analysis across parallel tasks.

4
Cross-Session Learning

Memories persist between sessions. Your agent gets smarter over time, not amnesic.

5
Sub-50ms Queries

Fast enough to enable aggressive decomposition. Spawn 10 sub-agents in parallel without latency penalty.

6
MCP Native

Works with Claude, Cursor, Windsurf, and any MCP client. No custom integration needed.

The Bottom Line:

RLM is the strategy (smart delegation).
Rembr is the infrastructure (persistent, searchable context).
Together: 80%+ cost savings + better accuracy.

The Research Behind Rembr

MIT RESEARCH • arXiv:2512.24601

MIT's Recursive Language Model paper demonstrated that intelligent context management:

Reduces token usage by 80%

Up to 2× better performance vs context stuffing

Handles 10M+ token contexts

Rembr implements this pattern with production-grade persistence that the research was missing.
