Partially VerifiedCompared to the previous-generation V4 Flash, V4.1 Flash reduces the demand for high-bandwidth memory (HBM) to one-quarter and the demand for SSD persistent storage to one-eighth.80% similarUnverifiedFlash Attention reduces the number of reads and writes to GPU high-bandwidth memory by reorganizing the computation order, achieving a 2–4× speed improvement without changing the computation results.74% similarUnverifiedV4.1 Flash has approximately 196 billion memory-related parameters, which are significantly larger than the model's other components and could theoretically be offloaded to CPU memory or SSD.70% similarUnverifiedFlash-type models typically reduce inference latency by 50-80%, lower API call costs by 60-90%, and maintain context windows in the range of 32K-128K tokens.68% similarUnverifiedThe larger the context window, the more cache is needed, the greater the memory footprint, and the slower the speed; taking Qwen 3.8 as an example, the cache for a 256K context window can reach 17 GB, making it twice as slow as a smaller window.68% similar
