AT-1 AI & models

Mixture-of-Specialists

A Mixture-of-Experts model fires only a few experts per query; the rest sit idle but still occupy RAM. AT-1 packs every specialist into one compressed, SHA-256-verified container, routes each query with a signed router, and streams only the routed expert — byte-identical to the full model, with a working set of one expert instead of all N. The specialists are public open-source weights; the verified vault, the signed router, and the streaming runtime are what AT-1 adds.

The container + the signed router

Each expert's tensors are individually addressable and hashed; the whole .at1w has a root hash. A side manifest (.at1m.json) holds the routing prototype per expert and the container root, Ed25519-signed. A tampered expert breaks its tensor hash; a moved routing centroid breaks the signature.

# pack N same-base specialists into one verified container + a signed router manifest
at1 moe demo            # end-to-end synthetic walk-through (pack -> route -> stream -> verify -> edit)
at1 moe keygen          # generate an Ed25519 router signing key

Routing — provable, not just functional

route(features) picks the expert whose prototype is nearest the query and returns a signed receipt binding features-hash → expert and the container hash — so you can prove, after the fact, which specialist answered a given request over which exact weights.

Streaming — one expert resident

load_expert(id)decompresses and SHA-256-verifies only that expert's tensors, hot-cached for reuse. The streamed weights are byte-identical to the source — it is the same model, defer-loaded and integrity-checked, so the output is provably the full model's output.

Editable, still verified

Add or remove a specialist and the container is rebuilt and re-signed; verify re-checks every expert hash, the container root, and the router signature.

at1 moe verify house.at1w
# re-hashes every expert tensor, re-checks the container root, and verifies the router signature:
# { "experts": 8, "tensors_checked": 96, "container_hash": "OK",
#   "signature": "OK", "VERDICT": "PASS" }

Verifying a container is free and needs no account; packing and serving experts are metered against the connected account — same as the rest of AT-1.
