Kimi K4 Status Tracker
Training started, release nowhere in sight
As of 2026-10-07, the official Kimi API Platform model list still has no K4; the models currently available are kimi-k3, kimi-k2.7-code, kimi-k2.7-code-highspeed and kimi-k2.6. Multiple outlets reported on 07-29 that Moonshot has started K4 training at a scale beyond K3; there's no official announcement, no date, no specs. This page tracks only what can be verified — rumors are labeled as such.

Current status at a glance
K4's current phase
On 07-29, Mydrivers and other outlets reported 'training started, at a scale well beyond K3.' No official announcement.
Release date
No official word or credible leak gives a date. The celebration banner only said 'push K4 to the absolute limit.'
K3's parameter scale (reference point)
K3 (released 07-16) is the largest open-weights model ever — Stable LatentMoE, 896 experts with 16 active.
K3's status on QCode
kimi-k3 is callable, billed per token; per-model prices are on /models. kimi-k2.6 was retired on QCode on 2026-09-09. Use K3 while waiting for K4.
What's actually known
The full set of verifiable facts: ① A banner leaked from Moonshot's K3 celebration event on 07-27 names the next generation K4; ② multiple outlets reported on 07-29 that K4 training has started, at a scale beyond K3; ③ beyond that — parameters, architecture, date, capabilities — there is no official information at all. Anything more specific is speculation.
Background: what K3 changed
The K3 release (07-16, at WAIC) pushed the ceiling of open-weights models to 2.8T; after the weights were open-sourced on 07-27, request volume spiked enough that Moonshot paused expanding consumer subscriptions.
Timeline
Kimi K3 launches at WAIC: 2.8T, the largest open-weights model in history.
K3 weights are open-sourced; the celebration banner carries the first mention of K4: 'charge the moon' / 'push it to the limit.'
Multiple outlets report K4 training has started, at a scale beyond K3. No new information since.
Confirmed vs rumors
Confirmed
K4 exists and is in training (multiple outlets on 07-29 + the celebration banner). Release date, parameters, architecture, pricing: all unknown.
Rumors
Any claim like 'K4 has xT parameters' or 'K4 ships in month X' has no source. The criterion is simple: without an official announcement or model card, treat it as a rumor. This page updates when official information appears.
Wait for K4 or use K3
Wait for K4
Fits: non-urgent, bet-style projects. Risk: no date — 'waiting' could mean months.
Use K3
Fits: work that needs doing now. K3 is already among the strongest open-weights models, with API and weights both in stock.
How to follow along
Watch only three first-party channels: Moonshot's official blog, the official X account, and the moonshotai org page on Hugging Face. K4 only counts when the name shows up on one of them. This page tracks in sync.
On QCode
There is no callable version of K4 — on any platform. On QCode you can call kimi-k3, billed per token, with per-model prices on /models (kimi-k2.6 was retired on QCode on 2026-09-09). If K4 is officially released with an API, check /models for whether QCode offers it.
FAQ
Has Kimi K4 been released?
No. As of 2026-10-07 the official model list still has no K4, and neither the Kimi API Platform changelog (latest entry: September 2026) nor the moonshotai org page on Hugging Face has a K4 entry. There are still only the 07-29 media reports that training has started — no announcement, no date.
When will K4 come out?
Unknown. K3 took 11 days from launch to open weights, but that was K3's pace — it doesn't extrapolate. Any specific date is a guess.
How big will K4 be?
The only basis is media reporting of 'a scale well beyond K3'; K3 is 2.8T. Any more specific number is speculation.
Will K4 be open-sourced?
Unknown. K3's weights were open-sourced, but Moonshot has made no commitment about K4.
What should I use now?
Kimi K3 (open weights + API in stock) or GLM-5.3 — both are on sale at QCode.
Where do I watch for official news?
Moonshot's official blog, the official X account, and the moonshotai org page on Hugging Face. Claims from anywhere else don't count.
