BeeLlama.cpp v0.4.1 Released: Improved KV Cache Quantization Performance

BeeLlama.cpp, a fork project of llama.cpp, has released v0.4.1, which includes new KV cache quantization features.

The key updates are as follows:

• KVarN (Variance-normalized KV-cache quantization): A quantization technique with increased precision per bit, optimizing VRAM usage while minimizing performance degradation compared to existing implementations.
• KV cache precision tail: A mixed-precision approach that stores some of the most recent tokens in BF16/F16 while quantizing the rest. This prevents the model from missing important task instructions or data.
• Additional standard KV cache types: High-precision types such as q6_0, q6_1 and low-capacity types such as q2_0, q3_1 have been added, widening the range of choices between VRAM capacity and precision.

This update is expected to be a particularly useful tool for users seeking to secure both inference performance and precision simultaneously, especially in environments with limited VRAM.
