OPTIC method achieves extreme compression for LLM embeddings

By PulseAugur Editorial · [1 sources] ·

Researchers have developed OPTIC, a novel method for extreme compression of per-layer embeddings in large language models. This technique achieves up to 1000x compression by using token-shared indexed codes and layer-specific affine decoders, significantly reducing memory usage with minimal impact on model performance. In tests with Gemma 4 E4B, OPTIC retained over 97% of the original model's performance at 100x compression, while also decreasing GPU memory requirements during inference. AI

IMPACT Enables larger language models to fit into memory-constrained environments, potentially accelerating deployment and reducing inference costs.

    Extreme Compression of Per-Layer Embeddings via Cross-Layer Latent Vector Quantization

    OPTIC achieves extreme compression of per-layer embeddings by using token-shared indexed codes and layer-specific affine decoders fitted to the output path, preserving most model performance at up to 1000x compression with minimal inference overhead.
