| | ## Model Description |
| |
|
| | Modern Large Language Models (LLMs) are constrained by a fundamental bottleneck: they generate text one token at a time. **CALM (Continuous Autoregressive Language Models)** confronts this challenge by introducing a paradigm shift in language modeling. Instead of predicting one discrete token at a time, CALM learns to predict a single continuous vector that represents an entire chunk of K tokens. |
| |
|
| | This is achieved through a two-stage process: |
| |
|
| | 1. **A high-fidelity autoencoder** learns to compress K tokens into a single vector and reconstruct them with near-perfect accuracy. |
| | 2. **A continuous-domain language model** then performs autoregressive prediction in this vector space. |
| |
|
| | ### Key Features |
| |
|
| | * 🚀 **Ultra-Efficient by Design:** Dramatically improves training and inference efficiency by reducing the number of autoregressive steps by a factor of K. |
| | * 💡 **A New Scaling Axis:** Introduces a new scaling dimension for LLMs—semantic bandwidth (K). Instead of just scaling parameters and data, you can now scale the amount of information processed in a single step. |
| | * 🛠️ **A Comprehensive Likelihood-Free Toolkit:** Operating in a continuous domain requires new tools. This repository provides the full suite of algorithms that make CALM possible: |
| | |
| | * **A Robust Autoencoder** to learn high-fidelity continuous representations of token chunks. |
| | * **Energy-Based Training**, a principled and likelihood-free method for generative modeling. |
| | * **BrierLM**, a new metric for calibrated, likelihood-free evaluation of language models. |
| | * **Temperature Sampling** for controlled, high-quality text generation using only a black-box sampler. |
