The AI OS for Autonomous AI Workers
LangChain gives you a loop. CrewAI gives you a team. BrainOS gives your AI Workers a brain that persists, learns from every task, and trains its own local LLM from its own outcomes. The longer it runs, the smarter it gets.
Brain + Living Model = compound intelligence. SE-aaS · AaaS · PM-aaS. 100% GAIA Level 1 (30/30). Trains its own Local LLM on its own outcomes. Production today.
Watch It Think
This is not a static diagram. BrainOS is a living system — 8 functional layers firing continuously, making discoveries, strengthening knowledge, and getting smarter every hour of every day.
What BrainOS Learned This Week
Every session BrainOS records a quality signal, updates federated knowledge, and adapts its strategy. Here's the live learning log — real RL signals, real discoveries, compounding every day.

AI agents are powerful. The infrastructure is broken.
Every major AI framework today builds on a stateless loop. No memory. No learning. No self-improvement. The model is smart — the operating system underneath is missing.
Today's AI forgets everything
Every conversation starts from zero. Agents built on LangChain, AutoGen, or raw API calls have no memory between sessions. They can't remember the last task they did, the mistakes they made, or what worked before. You re-explain context every time.
Today's AI never improves
When an agent gets something wrong, that failure disappears. There's no reinforcement signal, no failure memory, no calibration. The same mistakes recur. The same wrong reasoning paths are explored again. Intelligence stays flat — it doesn't compound.
Today's AI can't do real work
Single-step tool use breaks on hard questions. No backward planning. No adversarial verification. No multi-path exploration. Ask a complex research question and you get a confident hallucination — not because the model is bad, but because the infrastructure isn't there.
Half-solutions don't converge
RAG retrieves knowledge at inference — the model doesn't learn. Persistent agents keep state but the model underneath never changes. Fine-tuning is one-shot on static data. None of these compound. The model stays the same regardless of how much it runs.
Why Brain + LM together is different
BrainOS isn't RAG. It isn't persistent agents. It isn't a fine-tuned model. It's the combination of a persistent RL brain and a local LLM that trains on its own outcomes — backed by Reflexion, Voyager, CoALA, and DreamCoder research.
RAG retrieves from a fixed vector store — knowledge doesn't update. BrainOS records every execution outcome as a quality signal (0.25–0.90). High-quality results (≥0.7) strengthen federated knowledge edges. The knowledge base grows and improves with every task.
federated_knowledge edge weight += 0.1 (dopamine signal)Persistent agents have state between calls — but the model underneath never improves. BrainOS captures every high-quality task as LoRA training data. A local LLM fine-tunes on this workspace's actual outcomes. The model itself gets better at this domain.
quality >= 0.7 → llm_training_data insert → LoRA fine-tuneLangChain chains API calls. BrainOS runs a 5-phase cognitive cycle every 30 minutes: PRIME (read past reflections) → ASSESS (gap detection) → PLAN (Haiku planning) → EXECUTE (queue jobs) → REFLECT (learn from outcomes). The system plans for itself.
cognitive-planner.ts: 5 phases, 30-min cron, Reflexion episodic bufferBrainOS is to AI Workers what an OS is to a computer.
Memory, compute routing, RL feedback, and a local LLM that fine-tunes on this workspace's outcomes — all as infrastructure. Workers don't just persist. They get measurably smarter every hour they run.
Three Verticals. One AI OS underneath.
BrainOS powers three categories of autonomous AI Workers. Under every vertical: the same persistent memory, RL learning loop, and local LLM training — operating as shared infrastructure.

AI OS Capabilities — powers all three verticals
Every AI Worker built on BrainOS gets all 8 OS capabilities as infrastructure — memory, learning, reasoning, quality, and now a local LLM trained on its own outcomes. The OS runs. Workers compound.

Plug Your App Into BrainOS
BrainOS is infrastructure, not a product. Any developer can create AI Workers and inherit a production-grade OS — memory, learning, and self-improvement included. Four steps. That's it.
Create an AI Worker
Spin up a BrainOS AI Worker with a role, domain, and service capabilities. It gets a persistent brain from day one — memory, RL feedback loop, and context mesh pre-wired.
import { createWorker } from '@brainos/workers';
const worker = await createWorker({
workspaceId: 'your-workspace',
name: 'Delivery Intelligence',
role: 'se-aas',
domains: ['pod-match', 'early-warning', 'delivery-intelligence'],
});
console.log(worker.brainId); // Persistent brain assigned
// Brain IQ, memory, and RL loop active from session 1BrainOS Learns Automatically
No training. No fine-tuning. Every task the worker completes generates a quality signal (0.25–0.90). Dopamine signals strengthen federated knowledge. Failures get normalized into an anti-pattern library. It gets smarter every session.
// After every task, BrainOS records outcomes:
const result = await worker.executeTask({
query: "Which engineers are flight risks this quarter?",
context: { engagementId: 'eng_123' },
});
// Internally: Brain IQ routes -> SE-aaS domain -> RL signal
// quality >= 0.7 -> dopamine -> federated_knowledge strengthened
// quality < 0.7 -> gaba -> failure pattern normalizedQuery with Full Reasoning Depth
BrainOS routes every query through Brain IQ — simple queries use System-1 (< 100ms), complex ones engage System-2 with LATS reflection, self-consistency voting (K=1–5), and adversarial verification. All answers are grounded in the worker's memory.
const answer = await worker.query(
"Why is delivery velocity dropping on Acme account?"
);
// BrainOS pipeline:
// Brain IQ 0.91 -> System-2 activated
// -> backward chaining structures search
// -> context mesh pulls 27 parallel queries
// -> adversarial verifier disproves draft
// -> K=3 self-consistency vote -> 91% confidence
console.log(answer.confidence); // 0.91
console.log(answer.brainIQ); // 0.91 (System-2)Build On the Brain
Use the SDK, REST API, or MCP server. Give Claude direct access to any AI Worker's brain. Build dashboards, power automations, trigger alerts — your application inherits BrainOS intelligence without managing any of the infrastructure.
// SDK — access any worker from anywhere
import { getBrainContext } from '@brainos/workers';
const ctx = await getBrainContext(workerId);
// REST API — works from any language
fetch('/api/brainos/query', {
body: JSON.stringify({ workerId, query })
});
// MCP Server — give Claude a BrainOS Worker brain
// Claude can query workers, ingest signals, read memory
// and act on federated knowledge in real timeBuilt For Every Team

Use Cases
BrainOS powers autonomous AI Worker services that transform how organisations work. Each AI Worker is powered by 36 layers of intelligence — memory, RL feedback, and adversarial verification.
Software Engineering as a Service (SE-aaS)
AI Workers that understand your codebase, infrastructure, and delivery pipelines. 27 domains cover pod matching, early warning signals, scope creep alerts, and delivery intelligence. The worker remembers every past sprint, learns which interventions worked, and gets smarter every week. Brain IQ adapts depth of reasoning — simple queries use System-1 (<100ms), complex ones run full LATS + self-consistency.
Accounting as a Service (AaaS)
AI Workers that handle financial operations end-to-end. 11 autonomous agent types cover reconciliation, anomaly detection, cash flow forecasting, compliance monitoring, and more. Each worker has persistent memory of your chart of accounts, historical patterns, and seasonal rhythms. Failures are remembered — the same mistake doesn't happen twice.
Project Management as a Service (PM-aaS)
AI Workers that orchestrate cross-functional delivery. 7 domains cover sprint planning, risk detection, stakeholder communication, resource allocation, dependency mapping, milestone tracking, and retrospective analysis. Process Intelligence FSM handles structured workflows with HITL gates for EU AI Act Article 14 compliance.
Research & Analysis
AI Workers that handle multi-step research tasks requiring real-world data. Full 36-layer pipeline: web search with LRU cache, Wikipedia infobox extraction, backward chaining to pre-structure answers, adversarial self-verification, and self-consistency voting (K=1–5). GAIA benchmark: 100% on Level 1 (30/30), targeting 90%+ overall.
Enterprise AI Worker Fleet
Deploy multiple AI Workers, each with specialized capabilities and a shared workspace brain (L25–L29 federated knowledge). Workers collaborate via A2A protocols — one worker can call another. Brain IQ scales compute allocation per-worker based on task complexity. The fleet compounds intelligence: each worker's learning benefits all others through federated causal edges.
How BrainOS Compares
LangChain, AutoGen, and CrewAI chain LLM calls — the model never improves. BrainOS is an AI OS: persistent memory, an RL loop, and a local LLM that trains on its own execution outcomes. The model itself gets smarter.
| Capability | LangChain | AutoGen | CrewAI | BrainOS |
|---|---|---|---|---|
| Persistent memory across sessions | No | Partial | No | Full — per-worker + federated |
| Model gets smarter from every task (RL) | No | No | No | RL closed loop — dopamine/gaba |
| Trains own LLM from own outcomes (LoRA) | No | No | No | Local LLM on SageMaker — live |
| Adversarial self-verification | No | No | No | Adversarial Verifier — disproves drafts |
| Adaptive reasoning depth (Brain IQ) | No | No | No | System-0/1/2 — routes by complexity |
| Tool synthesis at runtime | No | No | No | DreamCoder — new tools from scratch |
| Failure memory (anti-library) | No | No | No | 14 anti-patterns, normalized, cached |
| Multi-worker fleet with shared brain | No | Basic | Basic | A2A + federated knowledge |
| GAIA benchmark performance | ~30% | ~40% | ~25% | 100% L1 (Round 10 — 30/30) |
| EU AI Act Article 14 compliance | No | No | No | Process FSM + HITL gates |
Common questions — answered with code
No. RAG retrieves from a fixed vector store — the model never updates. BrainOS records every execution as a quality signal. High-quality outcomes (≥0.7) write to federated_knowledge and feed LoRA fine-tuning. The knowledge base and the model both improve continuously.
recordOutcome() → quality signal → federated_knowledge += edge → llm_training_data insertYes — AutoGen and some CrewAI configs persist state. But the model underneath never changes. BrainOS's Living Model fine-tunes a local LLM on this workspace's outcomes via LoRA. The model itself learns this domain's patterns, not just the agent state.

Getting all three to converge is the moat. Backed by code, not marketing.
