Unconfirmed. Per an expert-call note circulating in investor communities, Zhipu's next-generation base model has 2.5 to 3.5 trillion parameters, well above the 1.6 trillion figure that circulated earlier. The note says pre-training of the more aggressive architecture stalled for a while with the loss no longer falling, that the problem has likely been fixed and training should finish soon, and that the model is expected to reach Claude Fable-level flagship performance. A second X account relaying the same details adds that Zhipu plans to keep using a single base for six months or more with continuous post-training, and that recursive self-improvement (RSI) has made some progress but is not yet the main driver of capability gains. Zhipu has not disclosed the parameter count, the training stall or a Fable comparison. Background: on Aug 31, chief scientist Tang Jie said the next base will be larger, without giving a number, and that it should be usable at full scale on day one; he also said the GLM-5 base was planned to be used for more than six months. The earlier 1.6 trillion figure was a media extrapolation at the time, not a leak.
Repeats the 2.5T-3.5T parameter range, the loss plateau and Fable-level target without naming a source; adds that a GLM-5 base is used for 6+ months with continuous post-training, and that RSI has made progress but is not yet the main driver. Not an official source.
Cites an expert-call note circulating in investor communities: next base 2.5T-3.5T parameters rather than the rumored 1.6T; pre-training hit a loss plateau under a more aggressive architecture, likely now fixed, training expected to finish soon; expected Claude Fable-level performance; inference speed and cost treated as hard constraints so it can be served at scale on day one. Not an official source.
Background, not confirmation: at Zhipu's Aug 31 interim results, Tang Jie said the next base will be larger but did not disclose parameters, aims for lower inference cost and full-scale serving on day one, and said the 744B GLM-5 base was planned to be used for more than six months.
