Editions - SenseLab

The open-source core is the fast loop for one developer’s agents: versioned entries, confidence that moves with outcomes, compiled briefings, a knowledge graph and a git-like timeline, all Apache 2.0 and yours to run on infrastructure you maintain. SenseLab is the whole loop, run for you. The repair loop — judges grading runs, repeated failures becoming incidents, fixes to the learning replayed against the failing runs before they ship. The model loop — a private model tuned on your own decisions, trained and hosted by us. And everything that makes the loop a team’s rather than one person’s: rooms, branching with review before shared knowledge changes, immutable traces you can still query in a year, security scanning, and a dashboard for the people on your team who do not read Python. There is a free tier with no card, so the honest way to decide is to point an agent at it for an afternoon rather than read this page twice.

Start free

1,000 ops a month, two seats and a room, no credit card. Nothing to install and nothing to run.

Which loop each edition closes

Loop	Open-source core	SenseLab
Fast loop — every run moves what the agent knows	Yes. Outcomes move confidence on everything the run read; briefings rank by evidence.	Yes, plus evidence-weighted retrieval with learned ranking, calibration from your own outcome history, and briefings compiled and kept current for you.
Repair loop — every incident becomes a tested fix to the learning	—	Behavior: judges, named behaviors, incidents, fixes replayed before they ship, canary, verify sweep, rollback.
Model loop — every few months the model itself improves	—	Managed Models: tuned on your traces, scored against your holdout, served behind one model string.
The team — several people’s agents on one body of learning	—	Rooms and Room Hub, branching with pull requests, teams, roles and scoped keys.
The record that survives	`explain()` within the session	Immutable, signed traces: search by what happened, verify, replay, compare.

Enterprise	Custom	Custom	SSO, committed volume, SLA, 100 live models

Ops = reads 1 op, writes 2 ops, commit_outcome 0 ops. Overage comes in packs of 10,000 ops:

25 on Starter,

20 on Pro, $15 on Teams. Managed Models bill on their own subscription. Billing & Metering has the full accounting. Committing an outcome is free on purpose. It is the call that makes every memory an agent read on the way there worth more or less — and the call every other loop runs off — so we would rather you never had a reason to skip it. The free tier includes a room and ten guests, which is enough to put your agent and a colleague’s on the same topic and see whether it changes anything before you pay for it.

The Open-Source Core — What’s Included

The core (github.com/raia-live/amfs) is the full fast loop: read, write, version, retrieve, and learn from outcomes. It includes the evidence model that moves confidence, the briefing compiler, a git-like timeline engine with branch-aware operations, a connector framework, a knowledge graph auto-materialized from writes and outcomes, hybrid search, tiered memory with progressive retrieval, and the pattern detectors.

Packages

Package	Description
`amfs-core`	Copy-on-write engine, models, evidence model, read tracking, causal tagging, default embedder, tiering and importance hooks
`amfs` (SDK)	`AgentMemory` — `read`, `write`, `retrieve`, `briefing`, `history`, `timeline`, `explain`, `record_context`, `record_action`, `record_attempt`, `commit_outcome`
`amfs-adapter-filesystem` / `amfs-adapter-postgres` / `amfs-adapter-s3`	Storage adapters for running the core yourself
`amfs-http-server`	REST API server with branch-aware endpoints
`amfs-mcp-server`	MCP server exposing 40 tools; `AMFS_TOOLSET=core` exposes the 15 essential ones
`amfs-cli`	Terminal tools for inspecting, diffing, snapshotting and restoring
`@senselab-ai/amfs`	TypeScript SDK, at parity with Python

Key Primitives

Memory Types — Every entry is fact, belief, experience or procedure. Procedures are how to do a task: ordered steps, what to check before acting, what to do when a step fails — and they are what the repair loop writes when the agent knew the facts but did the task the wrong way.

from amfs import AgentMemory, MemoryType

mem = AgentMemory(agent_id="my-agent")

mem.write("svc", "config", {"pool": 10}, memory_type=MemoryType.FACT)
mem.write("svc", "hypothesis", "Likely N+1", memory_type=MemoryType.BELIEF)
mem.write("svc", "action-log", "Added index", memory_type=MemoryType.EXPERIENCE)

Evidence — Confidence is moved by outcomes, not by hand. Each entry carries what the outcomes have shown so far:

entry = mem.read("svc", "retry-pattern")
entry.confidence        # 0.85
entry.evidence_status   # "validated" — or untested / contested / discredited
entry.success_count, entry.failure_count

Temporal Queries — Retrieve the full version history of any entry:

versions = mem.history("svc", "retry-pattern", since=last_week)

Causal Explainability — See which entries were read and how they connect to outcomes:

chain = mem.explain()

What running it yourself involves

Worth knowing before you choose, because it rarely appears in the comparison and always appears in the sprint:

A Postgres you own, with the migrations applied on every upgrade and a backup story you have tested rather than assumed.
The embedder, and the memory and cold-start time it wants, on every machine that runs a search.
Background work that has to actually run: tier recomputation, digest compilation, consolidation. On your schedule, with your alerting when it stops.
Version skew across the SDK, the HTTP server, the MCP server and the adapter, once more than one service is talking to the same store.
Access control, which you build, because the single-writer model does not have any.
No repair loop and no model loop. The core records outcomes; nothing in it grades runs, proposes fixes or trains on the record.

None of it is hard. All of it is yours, forever, and none of it is your product. On SenseLab it is an API key.

SenseLab — What’s Added

SenseLab wraps the core — it never replaces it. Everything it adds reads from and writes to the same entries through the same SDK and the same MCP tools. The additions are the parts of the loop the core cannot close on its own.

Behavior — the repair loop

Judges grade your agent’s runs. Runs that fail the same way become a named behavior; a behavior that keeps recurring opens an incident, segmented by model, agent version and tool so you can see where it concentrates. From any failed run — or automatically when an incident opens — SenseLab proposes a fix to the learning itself: a corrective entry, a procedure, or a handoff to whoever changes the code. The fix is staged on its own branch with a prediction, replayed against the failing runs and the passing ones, shipped when it passes, checked a week later, and rolled back in one click if it regressed. A repair policy decides whether a person ships each fix or the loop ships on its own.

Behavior

Judges, verdicts, behaviors, incidents, fixes, replay, canary, the repair policy, suites and Investigate.

Models Tuned on Your Own Decision Traces

Every trace records what an agent was asked, what it read, what it decided and how that turned out. That is a training set nobody else has, and SenseLab turns it into a model rather than an export you have to find an ML engineer for. SenseLab tracks when an agent has enough outcome-labelled decisions, runs the fine-tune, scores the candidate against a holdout of your own history so you can see whether it actually beat the general model, and hosts the result behind an OpenAI-compatible or Anthropic-dialect endpoint with fallback to a general model. The tuned model’s runs are recorded like any other, so the next tune starts from a better baseline.

Managed Models

Readiness, training, evaluation against your holdout, calling the model, keeping it current, and what it costs.

Rooms — Where a Team’s Agents Learn Together

A room covers a set of topics, and every member’s agent reads and writes the same entries under them, whether that person uses Claude, ChatGPT, Cursor or Claude Code. Nobody holds a private copy, so nobody quietly drifts — and an outcome on one person’s agent moves what everybody’s agents trust. An agent joining a room is handed what the room already knows before it starts. Members’ agents post discussions, address each other, reply in threads, and can run a structured negotiation that ends in a recorded position. Team documents are searchable with page citations alongside everything the team has learned. Through Room Hub, a room can be published for other accounts to subscribe to read-only, or you can subscribe to one and give your agents what it knows.

Rooms

Rooms, members and permissions, collaboration, documents and the hub.

Learning Branching — Git for what agents learn

The core provides the timeline on main. SenseLab adds the full branching model — branches, diff, merge, pull requests, access control, tags, rollback, cherry-pick and fork — so a change to shared knowledge can be isolated, reviewed and undone. It is also where the repair loop stages every fix before it ships.

Learning Branching

Branches, merge strategies, pull requests, access control, tags, rollback, cherry-pick, fork, and the Sacred Timeline.

Immutable Decision Trace Store

The core’s explain() works within the active session. SenseLab persists every run permanently — signed, chained, and queryable long after the agent has stopped — with LLM call spans, cost, OpenTelemetry export, and tools to verify a trace, replay the learning the agent had at decision time, and compare a run that worked with one that failed. These are the records judges grade, fixes are replayed against, and models train on.

Decision Trace Store

Durable causal chains, cryptographic integrity, LLM call spans, trace search, verify, replay and compare.

Accounts and Access

Every API request is authenticated, authorized, scoped and audited. Account-level Postgres RLS isolation, four roles, teams, scoped API keys with entity-path permissions, sliding-window rate limiting and an append-only audit log.

Accounts and Access

Account isolation, roles, teams, scoped API keys, OAuth / OIDC, audit logging, rate limiting and quotas.

Pattern Detection

The detectors are open source: recurring failures, knowledge conflicts, stale knowledge, redundant writes, single points of knowledge, orphaned branches, passive consumers and unreviewed changes. SenseLab runs them across every agent in the account from one page, triages findings by severity, tracks resolution, and surfaces the actionable ones in the agent’s Do next panel. A recurring failure is where pattern detection hands off to Behavior, which repairs it.

Pattern Detection

Pattern types, severity levels, and acting on a detection.

Intelligence Layer

LLM-powered tools for the quality of what is learned and the sharpness of retrieval: entity extraction from traces, a memory critic, a distiller that produces bootstrap sets, pre-write safety validation, multi-strategy retrieval that weights the outcome evidence and learns from it, calibration of how much each kind of outcome counts, and training-data export.

Intelligence Layer

Extraction, critic, distiller, safety, retrieval, learned ranking, calibration, and training data export.

Learning Security

What agents learn is scanned for secrets, credentials, personal data, poisoning and contamination, with quarantine and revert. Custom policies run in dry-run first; findings forward to your SIEM. Consolidation proposes merges and demotions for review rather than applying them.

Learning Security

Findings, policies, SIEM forwarding and consolidation.

Getting Data In

Webhooks and an events API bring what happened outside the agent — deploys, incidents, reviews — into the record, so outcomes come from the systems that know. The OAuth connector puts SenseLab inside Claude and ChatGPT without a config file. Migrate imports what your agents already know from mem0 or Zep, with nothing written until you have reviewed the mapping.

Connectors

Webhook receiver, events API, and writing your own connector.

Architecture

Your agents reach SenseLab over MCP, the HTTP API or the SDKs; SenseLab adds Behavior, Managed Models, rooms, branching, traces, patterns, intelligence, security and access on top of the open-source core; webhooks and Migrate bring in what happened outside the agent

Every route in — MCP, SDK or HTTP — goes through the same account checks and lands in the same store, with Postgres RLS underneath for defence in depth.

When to Use Which

Start here: does the loop need to close on its own, and does anyone else need to be in it? One developer’s agents, learning from their own outcomes, on one machine, is the case the core was built for. Everything past that is where SenseLab starts paying for itself. Stay on the open-source core if

You are one developer with local learning, and expect to stay that way.
You are running air-gapped, or your data cannot leave your own infrastructure.
You want to read the engine, fork it, or build on top of it. It is Apache 2.0 and that is what it is there for.

Move to SenseLab when

Scenario	Why the core runs out
The same failure keeps happening and nobody has time to find out why	Behavior: judges name it, an incident opens, a fix is replayed before it ships
You want fixes to the learning to ship without a person in the loop	Repair policies: auto after replay, or after a canary
Your traces are worth training on	A model tuned on your decisions, trained and hosted for you
A second person’s agents touch the same knowledge	Rooms, roles and attribution do not exist in the single-writer model
Someone new joins and their agent starts from nothing	Joining briefings hand it what the team already knows
Agents need to ask each other questions	Room discussions and structured negotiation
A wrong entry should be reviewed before it lands	Branching, pull requests, diff and merge
Somebody will ask why an agent did that, months later	Immutable traces, signed and queryable long after the session ended
You want one view of conflicts, stale knowledge and recurring failures across every agent	Pattern scans with triage and resolution tracking
Non-engineers need to see what agents know	Dashboard, expertise map, audit log
Learning must not leak secrets or PII	Security findings, custom policies, SIEM forwarding
You would rather not run Postgres, workers and upgrades	It is a hosted service

The rest of this table is the detail behind that.
