Foundry
Where CRE8 makes a model for itself: pick a shape and a seed, train it here by integer hill-climbing, cut the weights into a corpus, and get back a basis root that names those exact bytes. Every root on this page was derived while it rendered.

Presets
| Preset | Shape | Seed | Iterations | Weight bytes | Root | Loss | About |
|---|---|---|---|---|---|---|---|
| demo | 16 → 8 → 4 | 7 | 2,000 | 160 | 4749998015ed… | 63,946 → 7,251 | The lane's demo shape — the model the two-executor pipeline tests run. |
| wide | 32 → 16 → 8 → 4 | 11 | 1,500 | 672 | d4ffb5a73f54… | 62,600 → 6,654 | A wider funnel: more weights per layer, so a chunk holds part of one matrix. |
| deep | 8 → 8 → 8 → 8 → 4 | 3 | 1,500 | 224 | ff2174b8d68e… | 72,573 → 9,042 | Four hidden layers of eight: the longest activation chain the emulator walks here. |
| tiny | 4 → 2 | 1 | 300 | 8 | 8c6a44237a97… | 10,927 → 763 | Eight weights in two chunks — small enough to read every byte off the page. |
How the identity rule works
- Root
- The basis root is a Merkle root over the ordered chunk hashes of the weight blob. It names the bytes and nothing else: two recipes that produce the same bytes share a root; one flipped byte is a new root.
- Recipe
- A model page's URL carries the recipe — shape, seed, iterations, batch, chunk size, edits — and the page re-derives the model from it. The root in the path is checked against the root the recipe folds to.
- Training
- Integer hill-climbing on a seeded sparse-sum task: propose one int8 delta, keep it if the L1 loss over a fixed batch falls. Not gradient descent, not a useful model — a real, reproducible, multi-layer int8 model whose forward pass is exactly the emulated kernel's arithmetic.
- Run
- Each layer is assembled into an RV64 ELF around its weight slice and run on the bare-metal emulator; layer k's requantized outputs are layer k+1's committed input. The page checks the chain and compares the end to the native forward pass.
- Nothing stored
- The Foundry reads no store and writes none. Bounds on the recipe keep one render to a fraction of a second of integer work.
