A Chinese technology report from the outlet behind mydrivers.com has suggested that Moonshot AI may be developing a future Kimi K4 model with 5.4 trillion parameters. The report, published on November 7, indicates a target release for the second quarter of 2027, though it notes a possible delay into the third quarter.
The report sketches several possible releases rather than documenting a launched model. It claims a Kimi K3.5 model could have roughly three trillion parameters and arrive around the 2027 Lunar New Year. Additionally, the outlet describes a lighter Kimi K3 Flash as a potential release before the end of 2026. All names, sizes, and dates in the report remain claims and are not confirmed product commitments from Moonshot AI.
The proposed 5.4-trillion-parameter figure for the K4 would be larger than the 2.8-trillion figure the report assigns to the existing K3 family. However, total parameter count alone does not establish capability, inference cost or response speed. The article does not disclose an architecture, active-parameter count, context length, benchmark methodology or evaluation results for the rumored successor.
The report also discusses self-distillation and post-training as development priorities, but it provides no technical paper, model card, or reproducible evidence to evaluate those descriptions. Furthermore, a number attached to post-training data lacks a clearly specified unit, so it cannot reliably be converted into a token-count claim.
Recent hardware-adaptation announcements regarding running or fine-tuning Kimi K3.1 Pro do not authenticate the existence, specifications, or release timing of a future K4. For developers, there is no announced K4 API, pricing schedule, download, or access program. Until Moonshot publishes its own details, the report remains an unverified description of a possible roadmap.
