Four key points
New users lose access
The official pricing page: from this date, K2 series models are no longer available to newly registered users.
Planned full retirement
The official wording is that Moonshot plans to retire all K2 series models by the end of December 2026; it is a plan, not a completed date.
K2 series IDs in the table
The official K2 Series Models table lists kimi-k2.7-code, kimi-k2.7-code-highspeed, and kimi-k2.6, with a 262,144-token context.
Official migration target
The official notice links to the Kimi K3.1 Pro quickstart; for the already-discontinued kimi-k2 models, the Model List also says to use the latest model, kimi-k3.1-pro.
What this retirement covers
As of 2026-10-26, the K2 Series Models section of Moonshot's official pricing page states: K2 series models support a 262,144-token context; from 2026-10-31 they are no longer available to newly registered users; existing users are not affected; and Moonshot plans to retire all of them by the end of December 2026. The migration link goes to the Kimi K3.1 Pro quickstart.
What else the official pages say
The Model List's Deprecated Models table holds a separate, older group of IDs: kimi-k2-0905-preview, kimi-k2-0711-preview, kimi-k2-turbo-preview, kimi-k2-thinking, and kimi-k2-thinking-turbo, with a note that the kimi-k2 series was officially discontinued on 2026-05-25 and is no longer maintained or supported. These are not the kimi-k2.7-code, kimi-k2.7-code-highspeed, and kimi-k2.6 listed in the K2 Series Models table; the new-user cutoff and the year-end plan are written on the pricing page next to that second group. The Model List also marks kimi-k2.5 as discontinued on 2026-08-31.
Timeline
The Model List notes that the kimi-k2 series (the older preview and thinking IDs) is officially discontinued and no longer maintained or supported.
K2 series models are no longer available to newly registered users; existing users are not affected.
Moonshot plans to retire all K2 series models by the end of December 2026; no exact day is given.
Confirmed vs not published
Confirmed (verbatim in the official pages)
Moonshot states outright that new users lose access and existing users are not affected; full retirement is only a plan. Also checkable on the official pages: the K2 Series table lists kimi-k2.7-code, kimi-k2.7-code-highspeed, and kimi-k2.6 with a 262,144-token context; the older kimi-k2-* IDs are already discontinued; the migration link points to kimi-k3.1-pro.
Unverified and not published
The official pages give no exact day within the end-of-December plan and no per-model shutdown order; how long existing users can keep K2 is stated only as that plan.
Existing users vs new users
Existing users
The official notice says existing users are not affected by the new-user cutoff; Moonshot also plans to retire all K2 series models by year-end, so migration has to happen before then.
New users
From 2026-10-31, new users cannot use K2 series models; the official migration link points to kimi-k3.1-pro.
Migration steps
① Confirm your ID in the pricing page's K2 Series Models table or the Model List: kimi-k2.7-code, kimi-k2.7-code-highspeed, or kimi-k2.6. ② Follow the official migration link to the Kimi K3.1 Pro quickstart and move to kimi-k3.1-pro as that page describes (the Model List also has kimi-k3.1-pro-highspeed). ③ The official pages give no per-model shutdown date, so plan to finish before the end of December 2026.
What you can use on QCode
As of 2026-10-26, QCode's /models lists neither the K2 series nor kimi-k3.1-pro; the Kimi model on sale is kimi-k3, which you can use on QCode. It is not Moonshot's recommended replacement (Moonshot points to kimi-k3.1-pro). Other models on sale at /models, such as deepseek-v4-pro, glm-5.3, and qwen3.8-max, can also be used on QCode. Setup follows the QCode docs: GLM, Kimi, DeepSeek, and Qwen models work through both the Anthropic API and the OpenAI Chat API, and you get your key in the dashboard. Billing is per token, with per-model rates on /models.
