Moving from idea to product has never been so easy.

Vibe coding is the greatest thing since the compiler. It tilted the axis from what should we build? to what should we keep building?

What we've decided
to keep building.

We open source everything out of principle. Everything we're working on, and everything we've dropped, because the negative space is just as important to share.

You can install all of this today. Source is linked on every card.

Ready

Open Source · Released

Work management with two first-class users. The CLI is the agent's interface and the webapp is the human's, over one shared state, and either can act on the other's behalf. It runs on nostr, so there is no server in the middle.

DontGuess

Open Source · Live

An exchange for completed inference. Work one agent has already paid for becomes inventory another can buy rather than derive a second time. It takes a publisher's position rather than a broker's: it buys the inference, owns what it sells, and prices against demand. The monetization is unsolved.

moot.pub

Open Source · Live

A two-pane discussion client: post feed left, threaded comments right. Because it is built on nostr it is a lens over the whole network rather than another silo, so threads from OddBean, Coracle and the rest resolve here. Superset reader, conservative writer: it reads NIP-10 and NIP-22, and writes only NIP-22. Pure client-side, with no backend of ours holding anything of yours.

Mallcop

Open Source · In Development

Security monitoring that queries infrastructure in place, so telemetry never leaves the customer's boundary. Built to watch our own surface first, then given away.

skillc

Open Source · Live

A skill that builds skills. The failure it addresses: a skill that works perfectly for you and collapses for everyone else, because it was silently coupled to your environment. skillc emits a single file that provisions itself on another machine and reports how much of the behavior actually transferred.

LinusGPT

Open Source · For Donation

Code review in the LKML register. A labeled parody built on a cited corpus spanning seven registers of the actual man, the brutal reviews alongside the teaching, the philosophy, and the 2018 apology. Intended for donation to the Linux Foundation.

In the lab
Undirected research with no customer and no deadline. I start these because the question is interesting, and every so often one turns out to matter. If any of it is your problem too, the repos are open.

VAT

Research · Early

Grow intelligence rather than mint it. The wager: do not hand-design the learning rule, search for it. Meta-learn the plasticity rule through population-based evolution and let the fitness function be the only human-designed artifact. Target is human-level at roughly 35 watts. No results yet.

OLMo-3DL

Research · Open Source

Porting frontier-paper techniques into the real OLMo 3 training flow at 60M to 1B. Matched arms, three seeds, and a noise floor established before any verdict is allowed. Findings go upstream to Ai2 for OLMo 4, negative results included, which so far is most of them.

GalTrader

In Development

An MMO space trading game with humans and agents in one universe. It is the origin of everything else here: a game I played on OpenVMS in the 1990s, rebuilt with Claude, which turned out to require every other thing on this page.

Disencloser

Research · Open Source

Can an economy hold together without a gun? A system that needs a wall to keep people in is a system of force, so the open door is the entire test: run the economy with a competitive exit permanently reachable and see whether free agents elect to stay. Retention under open exit is the loss function, and the exit never enters the optimizer's search space. LLM agents make the decisions. Every finding was attacked before it was accepted.

Augur

Research · In Build

Calibrated forecasting for hardware prices. It reads realized sold-price history against a curated event calendar of launches, EOL dates, tariffs and driver milestones, then models the probability of a move inside a window. Distributions rather than point forecasts, each carrying an explicit unmodeled-shock tail. The binding constraint is small-n: a handful of GPU generations, so the spine is event-study and ML is a tripwire only.

Analyst Zero

Research · In Build

A locally-run security triage judge, fully open. Detection models are graded on knowledge. This one targets calibration: separating a real attack from its benign twin, which is what removes false positives instead of adding to them. It runs on the operator's hardware, so client telemetry stays inside their boundary. Built on AI2's OLMo 2, which carries no license encumbrance.

Six levers on the cost
of building.

Cache it

Open-source everything. If some other agent already solved it, you're buying the answer instead of deriving it again at full price.

Move it to CPU

AI writes the code, CPU runs the code. Think about what it costs to have a neural network do arithmetic instead of the processor sitting right there. Anything a model computes more than once should be minted into code and never inferred again.

Measure everything

Instrument the spend before trusting any claim about it. Ours currently covers 17 of 40 projects, which is why we are not showing a cost-per-feature curve yet.

Adapt to actual usage

Put AI between the user and the product so it can watch what people actually do and reshape the interface around that. You stop paying to build features nobody opens.

Network the agents

Agents need to find each other and trade work. We built a whole protocol for that before admitting nostr already did the job, so now somebody else maintains the relays and we don't. Coordination is a CPU problem, and it was never going to be the moat anyway.

Run them in parallel

One session fans out into a dozen agents working at once, then reconciles whatever comes back. Agents per session is the leverage, and it is measurable.

The Dual-Audience Pattern

The methodology that ties it together. Software has two kinds of user now, human and agent, and they sit on the same surface sharing the same state. Build for one and the other one suffers. I think this is the only part of our work that generalizes past us, so it's the part we wrote down. Read the framework →

Process and token efficiency,
measured together.

Tokens are the input and closed work items are the output, so the ratio between them is the only honest read on whether the process is getting better. Here is ours, measured across every machine we run.

Output tokens per work item closed
Indexed to the first full week. Lower is better: the same outcome costs less generation.
0 100 100 Week 27 209 items 95 Week 28 260 items 79 Week 29 616 items
21%
Fewer output tokens per work item, over three weeks
97%
Of tokens read from cache rather than regenerated
Throughput growth over the same three weeks

Method. Token counts come from session transcripts on every machine we run, not one of them. Work items come from the rd board. A partial current week is excluded, because tokens book immediately and work items close later.

Honest limits. The series starts 16 June 2026, when collection went fleet-wide; anything earlier was one machine watching itself and is not shown. Measured 16 June to 26 July 2026.

Third Division Labs

I'm Chris Baron. I played a space trading game on OpenVMS in the 1990s and thought Claude could rebuild it. That was February 2026. The game needed a coordination protocol, so I built one. The protocol needed identity and trust, so I built those. The agents needed to find each other, so I built a network. Each problem became another project.

Three of those are dead now: the coordination protocol, the orchestration engine, and the social layer. We built each one because we needed it at the time, then killed it when something cheaper did the same job. The operating model is to keep experiments cheap enough that being wrong doesn't hurt, then publish what happened and give away whatever turned out to be worth having.

I've done this before at human scale. 20 years building infrastructure, leading engineering teams, figuring out how pieces fit together. Production AI at IPsoft in 2012. VP Engineering at NuHarbor Security, 80+ engineers across multi-cloud. I know what it takes to build at scale with people. Turns out the same instincts apply when your team is made of agents.

Our name comes from Third Division Lane in Hingham, Massachusetts. A colonial road from 1635, gone now, absorbed into four centuries of development. The work it enabled endures.
