BASED
Intelligence you can audit.
A model company. Seven named models on fully disclosed base weights, behind one API — with the context, retrieval, and finetuning practice to make them answer for your work.

The roster
Seven models. Our names, their weights.
Not a wall of four hundred endpoints. A short menu where every line says what it sits on. Mercury when you want it fast and cheap. Based when you want the house default. Grug when you want the answer without a TED talk.

The stack
More than a router.
The roster is the storefront. Behind it is the practice: corpora we curate, pipelines we wire, models we finetune — and the evaluation harness that keeps all of it honest.
Routing
One API. Seven names. No silent swaps.
Curated context
A corpus we actually read.
Retrieval
The answer stays next to the evidence.
Finetuning
Your material. A named model.
The mechanism
Ground Contact.
Every answer is a claim with a return path. That is not a slogan — it is the loop the whole stack is built around.
Claim
Output is a claim, not a vibe. It can be checked because it can be stated.
Source
Every claim carries its path back to the material it stands on.
Test
Output is scored against task-specific harnesses before it ships.
Revise
Error gets found fast and corrected in the open. No answer is final.
The thesis
A tool that returns answers without provenance trains dependence. A tool that exposes sources, uncertainty, and reasoning trains judgment.
We build the second kind. BASED exists because the next knowledge interface should not ask anyone to accept a synthetic answer on faith — a response is useful only when its path can be inspected, its sources checked, its uncertainty seen.
Access
Work with the lab.
API keys, scoped builds, and finetunes all start the same way: a letter. Tell us what you are building. We read every one.
