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. 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.
• Approximately 110 million parameters.
• 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.

Limitations

Neo is trained on synthetic English decision records and may fail on unseen schemas, ambiguous contexts, distribution shifts, adversarial options, or languages other than English. Calibration and accuracy are task-dependent. Always validate with held-out, task-specific data and add human oversight for high-impact workflows.
