Ollaya package of amyrmahdy/decima-small and amyrmahdy/decima-base and amyrmahdy/decima-agent by A. M. Madani (amyrmahdy). Ollaya runs open decision models locally, the way Ollama runs LLMs: typed questions in, calibrated answers out, behind a TypeSafe-compatible API. This repository holds only the files Ollaya derives, with no weights. Each graph is an ONNX export of the original model whose weights reference the authors' own weight files by byte offset, so ollaya pull downloads the weights from the upstream repositories, unmodified and pinned to a commit, and verifies their sha256. Each tag has an fp32 graph, used on CPU and GPU. Each tag also has decision.json (sequence layout, special…

What is in this repository

This repository holds only the files Ollaya derives, with no weights. Each graph is an ONNX export of the original model whose weights reference the authors' own weight files by byte offset, so ollaya pull downloads the weights from the upstream repositories, unmodified and pinned to a commit, and verifies their sha256.

Tag Upstream Files
decima:small amyrmahdy/decima-small@2e7f4d0 small/model-fp32.onnx, small/decision.json, small/calibration.json
decima:base amyrmahdy/decima-base@2468005 base/model-fp32.onnx, base/decision.json, base/calibration.json
decima:agent amyrmahdy/decima-agent@5c14a46 agent/model-fp32.onnx, agent/decision.json, agent/calibration.json

Each tag has an fp32 graph, used on CPU and GPU. Each tag also has decision.json (sequence layout, special tokens) and calibration.json (temperatures).

Parity

Ollaya's Rust runtime matches the author's own code (decima/model.py, render.py and systemone.py, fp32) on 581 questions from 122 requests for each of small and base, and 591 questions from 132 requests for agent 2.2, ten of them too long for the option window, on CPU and CUDA (RTX 4090 and RTX 5090): identical token rows and truncation, the same 18 rejected requests, the same decision on every question, scores within 2.2e-5 and probabilities within 5.4e-6.

License

Same as the upstream model (Apache-2.0). Ollaya itself is Apache-2.0.

If you haven't already, you can install the Transformers.js JavaScript library from NPM using: Note: Having a separate repo for ONNX weights is intended to be a temporary solution until WebML gains more traction. If you would like to make your models web-ready, we recommend converting to ONNX using Optimum and structuring your repo like this one (with ONNX weights located in a subfolder named onnx).
