Unverifiedv4.1 Flash's expert weights are shipped natively in FP4 (4 bits per parameter) and no 8-bit version has ever been released; being close to the compression limit of this format, it cannot be further quantized for Agentic tasks.73% similarUnverifiedThe domestic chip route is an important enabler of GLM-5.3 Flash's 1/100 pricing, as freedom from dependence on imported computing power allows for a redesigned inference cost structure.72% similarUnverifiedGLM-5.3 Flash achieved nearly 20% weekly token call share on the OpenRouter platform, ranking first among all models.72% similarUnverifiedFlash models typically use GQA or MQA technology to compress the KV Cache by 4–8×, thereby supporting higher concurrency on the same hardware.70% similarPartially VerifiedThe V4.1 Flash beta is open with no barriers—anyone with API access can use it, at a price identical to the current V4 Flash.70% similar
