NEO - Decision Model

## Ownership and contact TokenAI is a non-profit startup founded in 2025 by Assem Sabry, based in Alexandria, Egypt. The Neo model, source code, training data, documentation, and related materials are owned by TokenAI. Contact: **info@tokenai.llc** · https://tokenai.llc ## Summary Neo is a compact TokenAI System One decision model for selecting actions from a declared candidate set. It reads English application context and a typed decision schema, then returns calibrated outputs for `choice`, `score`, and `noul` in one encoder forward pass. It is not a conversational or free-form text-generation model. Canonical model: `tokenaii/Neo` — https://huggingface.co/tokenaii/Neo Training dataset: `tokenaii/Neo-dataset` — https://huggingface.co/datasets/tokenaii/Neo-dataset Complete source repository: [github.com/tokenaii/Neo](https://github.com/tokenaii/Neo). It contains the complete project source code, training code, synthetic-data generation code, evaluation and benchmark scripts, configurations, examples, documentation, licenses, and reproducibility materials. ## Model architecture - Bidirectional Transformer encoder, initialized and trained from scratch. - 41,391,654 trainable parameters (approximately 41.4 million). - 8 Transformer layers; hidden size 512; 8 attention heads. - Intermediate size 2048; maximum context 1024 tokens. - Typed heads: `choice`, `score`, and `noul`. - Choice head: up to 32 candidate options per question. - Score head: up to 5 ordered levels. - Noul head: binary probability for a yes/no or escalation decision. - A request can contain up to 8 independent decision questions. ## Input and output contract The input is English text plus a predefined decision schema and candidate options. The output contains typed probabilities and the selected index or level. Applications should apply their own confidence thresholds, abstention rules, validation, logging, and human review. Neo does not execute tools and does not replace authorization or policy enforcement. ## Intended uses Non-commercial research and education for tool routing, workflow selection, request classification, department routing, escalation detection, validation gates, and selecting the next action in an agent pipeline. ## Out-of-scope uses The license prohibits commercial, monetized, paid, sponsored, client-facing, production-business, or financially beneficial use. Do not use Neo for unsupervised medical, legal, financial, employment, housing, admissions, insurance, credit, safety-critical, government-benefit, law-enforcement, or irreversible decisions. ## Training records Training code, configurations, live logs, loss history, checkpoints metadata, evaluation reports, and benchmark history are maintained only in the GitHub source repository: https://github.com/tokenaii/Neo/tree/main/docs/training This Hugging Face model repository does not publish the training history or benchmark archive. ## Tokenizer Neo uses the standard English `bert-base-uncased` tokenizer and vocabulary, published under `tokenizer/` for repository organization. A custom tokenizer was not built. The Transformer parameters are Neo's own randomly initialized and trained weights; the tokenizer vocabulary is not the model architecture. ## Release status The English-only training run is complete and the verified `model.safetensors` checkpoint is published in this repository. Training logs, loss history, evaluation reports, and benchmark records remain exclusively in the GitHub source repository. Do not infer benchmark accuracy from the architecture or data counts. ## Repository layout - `licenses/MODEL_LICENSE.md` — full model license. - `licenses/NOTICE.md` — attribution and ownership notice. - `assets/neo-cover.png` — repository artwork. - `docs/MODEL_SPECIFICATION.md` — technical specification. - `model.safetensors` — verified model weights. - `tokenizer/` — standard English `bert-base-uncased` tokenizer files. ## License and attribution Use is governed by [the TokenAI Neo Model License](licenses/MODEL_LICENSE.md). Redistribution, renaming, rebranding, white-labeling, Derivative Models, Commercial Use, and Financial Benefit are prohibited without written permission from TokenAI. Every permitted downstream report or model must state: > This work was trained using the TokenAI Neo Decision Model Dataset: > `tokenaii/Neo-dataset`.

Calibration and accuracy are task-dependent. Always validate with held-out, task-specific data and add human oversight for high-impact workflows.
