THE MODEL SHELF · 23 OCTOBER 2026
One live demo. A preserved model history.
Choose with the full picture: the current browser demo and the trained 9B archive serve different purposes.
Our 9B checkpoints
The unchanged 9B base and experimental adapters used MLX on a Mac. The adapter conversion to PEFT passed small native parity checks. A verified Transformers.js export is still missing.
View the actual adapter archive ↗Verify the converted model
Before enabling 9B here, we need browser-compatible weights, checks that the adapter is active, matched text and image outputs, and measured device memory. Publishing the page alone does not complete that work.
Read the export status ↗THE METHOD
What the harness does
A browser-side structure around the model, designed for readable work rather than a bare answer.
Frame the problem
Subject, exam, expected answer type and possible thermodynamics sign conventions become explicit before generation.
Choose a route
The prompt asks for givens, a short subgoal plan, essential calculations and all requested branches.
Show the limits
The page checks requested sections and runs a separate calculation for one simple kinematics pattern. Other mathematical steps remain unverified.
This first browser harness does not yet have a general symbolic checker or calculator. Those are research tasks, and the 9B MLX adapters cannot be loaded by Transformers.js as-is.
THE RECORD
The results, including the setbacks.
The 9B training work and this browser demo are separate experiments. The archive shows the actual checkpoints and what each taught us.
9B TRAINING ARCHIVE
No adapted checkpoint has been promoted as a better solver.
Our latest controlled studies changed training families and LoRA layer coverage. Some outputs improved, others regressed; none passed the full selection rule.
