Your KV cache is overflowing VRAM at the batch size you...

The most effective architectural lever is GQA, which reduces the number of KV heads from N to N/G (typically G=8), shrinking the cache by 8x with minimal accuracy impact. Other effective strategies include KV quantization, such as using INT8 to halve the cache size, or applying sliding-window attention on non-critical layers to limit the context stored in VRAM.
