The company vaguely attributed the adjustment to prevailing economic circumstances, which perceptive observers might interpret as a reference to both Donald Trump's tariff measures and the worldwide artificial intelligence competition inflating electronics costs.
According to the data sheet, this has 200ns access time, or 0.2μs, but read on in the datasheet to find 375ns cycle time.

Processing nearly one trillion genetic tokens demanded substantial infrastructure optimization. For the billion-parameter version, the team integrated FlashAttention-2 through NVIDIA's BioNeMo framework built upon NeMo, Megatron-LM, and Transformer Engine. To enable FlashAttention-2, they reconfigured feed-forward dimensions to ensure divisibility by attention head count—a strict compatibility requirement. Combined with bf16 mixed-precision training, these modifications achieved approximately 5x training acceleration and 4x micro-batch size enhancement on H100 80GB GPUs. For inference, implementing Megatron-Core DynamicInferenceContext with key-value caching produced over 400x faster generation compared to basic implementations.
