EBT

Energy-Based Transformers (EBT) is a PyTorch research implementation enabling generalized reasoning and scalable learning across modalities (NLP, images, video). The codebase provides training and inference scripts with support for distributed training, multiple model sizes, and System 2 thinking capabilities.

What EBT is

EBT implements an energy-based approach to transformer architectures that enables reasoning over every token prediction. The codebase includes PyTorch Lightning trainers, modular model definitions, multi-modal dataset handling, and support for both single-node and distributed training via SLURM or direct execution.

Quickstart

Get the EBT source

Clone the repository and explore it locally.

terminalbash

Best use cases

Research & Paper Reproduction

Directly reproduces Energy-Based Transformers paper results. Well-suited for academic evaluation, benchmarking, and extending the published work across modalities.

Multi-Modal Model Development

Demonstrates scalable training across NLP, image, and video modalities with consistent abstractions. Useful as reference architecture for building generalizable reasoning systems.

HPC Training at Scale

Provides SLURM integration, multi-node support, and distributed training infrastructure. Suitable for teams with GPU clusters wanting to train large language models with energy-based objectives.

Implementation considerations

Requires Python 3.12, PyTorch, and GPU (at minimum single A100; multi-node training recommended for reproducibility). Alternative requirements files provided for GH200s and non-NVIDIA setups.
Setup involves conda environment creation, HuggingFace token authentication, WANDB logging setup, and optional FFPROBE for video datasets. Caching directories must be configured via environment variables.
Training entry point is bash scripts in `job_scripts/` that pass hyperparameters to `train_model.py`. Key parameters (RUN_NAME, MODEL_NAME, MODEL_SIZE) must be manually edited; model architecture auto-scales with MODEL_SIZE.
Inference requires a pre-trained checkpoint file and inference-mode execution flags. Complex inference procedures (System 2 thinking, self-verification) available but require custom configuration.
Code is modular: model architectures in `model/`, training loop in `base_model_trainer.py`, datasets in `data/`. Minimal training loop example provided for reference implementation.

When to avoid it — and what to weigh

Production Deployment — This is research code without stability guarantees, versioning, or production hardening. No official release versions, minimal issue tracking, and active development status make production use risky.
Minimal Dependencies or Edge Devices — Requires PyTorch, Lightning, HuggingFace, WANDB, and GPU resources (A100 class recommended). Not suitable for lightweight inference or offline-first scenarios.
Quick Prototyping Without ML Expertise — Requires understanding of distributed training, SLURM, hyperparameter tuning, and deep learning infrastructure. Setup involves environment configuration, dataset caching, and HPC knowledge.
Pre-Built Model Inference Only — No pre-trained checkpoint repository, model zoo, or easy inference API provided. Users must train models from scratch or obtain checkpoints externally.

License & commercial use

Licensed under Apache License 2.0 (Apache-2.0), a permissive OSI-approved license. Allows commercial use, modification, and distribution under standard Apache conditions.

Apache-2.0 permits commercial use. However, this is research code without production guarantees, stability commitment, or vendor support. Commercial deployment would require internal validation, testing, and maintenance responsibility. No commercial indemnification or SLA provided.

Security considerations

Code execution considerations: requires handling of HuggingFace tokens, WANDB API keys, and cluster credentials in environment variables. No explicit security audit documented. Dependency security relies on PyTorch/Lightning/HuggingFace upstream. FFPROBE video processing introduces external binary execution; validate video input sources. No encryption, authentication, or isolation features in codebase itself.

Alternatives to consider

Hugging Face Transformers + Lightning

Provides pre-built transformer models, extensive documentation, and production-ready inference. Better for teams not researching energy-based methods or needing immediate deployment.

OpenAI GPT or Claude API

Managed inference without training infrastructure requirements. Suitable if reasoning capability is needed without model ownership or training cost.

JAX/Flax Implementation

Alternative frameworks for scalable training with different performance characteristics. Useful if you have JAX expertise or prefer functional programming paradigms.

EBT FAQ

Can I use this code to inference pre-trained EBT models?

Yes, inference scripts are provided in `job_scripts/nlp/inference/` and other modalities. You must supply a pre-trained .ckpt checkpoint file. No model zoo or pre-trained weights repository is published; checkpoints must be obtained from the authors or trained from scratch.

What GPU hardware is required?

At minimum a single A100-class GPU for single-node training. Multi-node training on HPC clusters recommended for reproducibility. Alternative requirements files provided for GH200s. Non-NVIDIA setups possible via `loose_requirements.txt` but GPU support will be limited.

Is this production-ready?

No. This is research code published to accompany a paper. No production hardening, stability guarantees, versioning scheme, or support SLA. Commercial use is permitted under Apache-2.0 but requires internal validation and maintenance responsibility.

How do I add a new dataset or model?

Model architectures are in `model/` directory; datasets in `data/`. Refer to CODE_INFO.md and existing implementations. Changes typically needed in model definition files and `base_model_trainer.py` dataset setup. Minimal training loop example shows basic structure.
