Optimizing Key-Value Cache for Swift Language Model Inference

• Innovation: A method dubbed ‘Keyformer’ designed to reduce KV Cache size in the generative phase of LLMs.
• Approach: Selecting key tokens for retention in the KV cache using a new scoring function to lower memory overhead.
• Results: Demonstrated improvements in inference latency by 2.1 times and token generation throughput by 2.4 times.
• Impact: Keyformer showcases practical enhancements in efficiency without negatively impacting accuracy.

The ingenious Keyformer approach tackles a crucial performance bottleneck in generative language modeling. By elevating the efficiency of memory utilization during the inferencing phase, it paves the way for faster and more responsive AI applications. Such optimization strategies are key for scaling up LLMs to handle larger contexts and lengthier text generation demands.
