## ⚡ Overview

**DM-JEPA 1.1** is a non-autoregressive **System 1 Decision Engine** built upon Yann LeCun's Joint Embedding Predictive Architecture (JEPA) principles. Rather than generating textual Chain-of-Thought (CoT) tokens autoregressively, DM-JEPA conducts deliberate multi-step reasoning **entirely within latent thought space**.

- **Sub-35ms Latency**: Delivers **34.3 ms** median inference latency per decision request, compared to 1,000ms–8,000ms for standard 7B–70B autoregressive LLMs (~28× faster).
- **Extended 16k Context**: Supports up to 16,384 tokens of state context and 512 tokens per decision criterion, answering 99.84% (150,518 / 150,759) of the Decision Index full panel.
- **Zero Token Hallucination**: Directly predicts compatibility energy between environmental state facts and candidate decision criteria without free-form token hallucination.
- **Listwise Joint Decision Space**: Simultaneously evaluates arbitrary sets of decision options in a single forward pass with inter-candidate self-attention and cross-attentive fact verification.
- **Official Decision Index Full-Panel Score**: **23.16 Balanced Skill** / **41.92 Balanced Raw** across all **150,759 requests** of the full Decision Index suite ([view evaluation dataset](https://huggingface.co/datasets/DangerLabs/decision-index-results)).

1. **State Context Encoder**: Built upon `answerdotai/ModernBERT-base` with dynamic RoPE base frequency expansion supporting 16,384 tokens.
2. **Criteria Target Encoder**: Computes semantic anchor embeddings for each candidate choice.
3. **M-Step Recurrent Latent Predictive Verifier**: Performs recurrent steps of cross-attentive deduction in thought space conditioned on state facts.
4. **Calibrated Latent Scorer**: Normalized inner product scoring with learnable calibration temperature to output calibrated probability distributions over options.
