Have been using this model all day yesterday. With its new architecture, this release is just as big as R1 and will redefine all future models. It is such a big difference when you have a model close to 5.6 Sol, but it is 5 times faster and super cheap. 71.7K views · 1.3K likes · 72 reposts · 28 replies Open on X →

One dead giveaway is also that Zhipu is one of the only labs that serves models with pretty poor partial prefill tok/s while output tok/s are fast. This model is ~30% faster than GLM 5.3. If the infras is the same, likely ~300-500B or fewer params vs activated params. 16.4K views · 114 likes · 5 reposts · 3 replies Open on X →
