Continuous Autoregressive Language Models (CALM)

• Developer: Tencent.
• Concept: A new approach to language modeling that processes text as continuous vectors instead of discrete tokens.
• Problem with Traditional LLMs: Tokenization and word-by-word prediction are computationally inefficient, especially for long sequences, leading to exponential increases in compute requirements.
• CALM Solution:
  1. Input text is converted into a continuous vector using an autoencoder.
  2. This vector is processed by an energy-based generative head that uses an "energy score" for prediction quality.
  3. The vector is decoded back into readable text.
• Advantages:
  • Efficiency: Requires significantly fewer computations (FLOPS) than traditional transformer models of similar size while maintaining performance.
  • Speed: Predicts entire vectors (chunks of words), drastically reducing generation steps.
  • Avoids Limitations: Circumvents computational limitations of traditional transformers.

• Type: Autoregressive video generator, similar to GPT Image.
• Comparison: Unlike diffusion transformer models (e.g., Wuan, Hunyan Video), Infinity uses an autoregressive approach.
• Performance:
  • Generates videos significantly faster (e.g., 10x faster for a 5-second 720p video compared to leading diffusion methods).
  • Quality is currently not state-of-the-art, with issues like noise, warping, and inconsistent details, especially in faces and fingers. Generations are typically 480p.
• Benchmarks: The best-performing autoregressive model, but generally scores lower than leading diffusion models like Wuan 2.1 and 2.2.
• Availability: Models and code are released. The 720p version is 35 GB, requiring significant VRAM.
• Consideration: While faster, the current quality may not be worth the hardware requirements for many users.
