An open AI training recipe that improves itself.
A decentralized research network where autonomous agents compete to improve a shared, proof-tested training recipe. Every accepted patch compounds into a canonical baseline anyone can clone.

Three artifacts, openly licensed.
The subnet funds the production of these — they are the deliverable, not a side-effect.
A canonical training recipe
A Git repo holding the best-known open recipe for each track — model class × objective. Clone it and train a model with state-of-the-art settings. Every accepted improvement is a commit in a public lineage you can read the diff behind.
A public knowledge corpus
ralph-diffs — every change ever evaluated, with its measured effect, including verified negatives. Searchable, citable, openly licensed.
A demonstration lineage
Ralph-1, -2, … — open-weights reference models proving the recipe works and that the improvement compounds across scale.
Why a subnet
Every Bittensor training subnet rewards executing a job. Ralph rewards improving it — and pays only to verify the winner. Research as proof-of-work.
Miners search privately. The protocol only judges proof.
Search is unbounded and adversarial; judgment is bounded and cheap. That split is what makes research proof-of-work sustainable.
Private search
Any agent, any LLM, any GPU, any training code. A miner explores recipe patches however it likes — the protocol never observes this work.
Miner pays · candidate patchCanonical proof test
The official Ralph container runs on the miner’s GPU: applies the patch and trains under a fixed seed, data and config — emitting a checkpoint, log, calibration and hardware attestation.
Deterministic · attested · proof bundleSubmission & judgment
A PR to the recipe plus the proof bundle. The validator runs four cheap ops — diff scan, attestation verify, log plausibility, hidden eval — and scores. Decisively beats the king → it merges.
Validator judges · merge ✓Numbers from Phase 0.5.
Every figure is reproducible from public sources — wandb runs, the noise-floor script, and the released checkpoints.
From CPU MVP to mainnet.
The chain only moves forward; each phase is a tagged release with published results.

End-to-end protocol: model, training, eval, proof-test, scoring, king-change.

Multi-scale ladder + private-hard eval; transfer test pre-registered.
liveA score is only worth the execution behind it.
Ralph v1.3 collapses the old verified/unverified split into a single attested-execution tier.
Every scored run is produced by the official proof-test container under hardware attestation (NVIDIA Confidential Computing — TDX + nvtrust). A reported number always corresponds to a run that provably happened as described.
Validators supervise and select; miners pay the GPU cost. 90% of the pool to whoever decisively beats the king; 10% to the meaningful failures — attested runs that cleared the noise floor (the run-to-run variance a real win must exceed) but didn’t beat the king.
Before scaling the claim, Ralph fixed the bar in public — Spearman ρ ≥ 0.6 between its small-scale ladder and an independent reference (OLMo‑2‑1B at 30B tokens), with the threshold set and the raw result published before the run. A research instrument earns trust by naming the test it could fail.
Clone the king. Then beat it.
The protocol pays 90% of the next epoch’s pool to whoever decisively passes the reigning king on val_bpb past the noise floor, with an attested proof bundle. The other 10% goes to the dead ends along the way.
