Moonshot AI has restarted training on a successor to its Kimi K3 model and reopened consumer subscriptions after a two-month pause, according to a leak from a source with a track record of accurate predictions. The next model in the Kimi K3 line is reportedly being optimized for computer use and multimodal capabilities, with an unconfirmed target launch before the end of October.

What Just Happened With Kimi Subscriptions?

On September 18, 2026, Moonshot AI reopened consumer subscriptions to Kimi after closing them on July 20, 2026, just four days after the Kimi K3 model launched. The company had paused new sign-ups because demand for K3 had exceeded its computing capacity. The reopened subscriptions come with restructured pricing tiers, though annual costs remain unchanged.

The subscription changes include several practical shifts for users. The company largely withdrew its plan to sell Kimi Code as a separate add-on after user pushback, meaning Code access is now included in the Plus, Pro, and Max plans. However, the cheapest tier no longer includes Code, effectively raising the entry price for Code access from 468 to 948 yuan per year. Users have also reported that weekly limits were removed while overall quotas were reduced, and the 1-million-token long-context benefit moved from the mid-tier plan to the Max tier.

When Could the Next Kimi Model Arrive?

A leak posted on September 19, 2026, claims that Moonshot AI has already begun post-training on the next model in the Kimi K3 line. Post-training is the stage after initial model training where a model is refined into a usable product. According to the leak, the new model will focus on computer use and multimodal improvements, with a claimed arrival before the end of October.

However, this timeline comes with significant caveats. The leak provides no official confirmation, model card, weights, API identifier, pricing, or release date. The source is a single X post from an account with a mixed track record; while the account correctly predicted some Kimi developments, its previous date prediction for a Kimi release was inaccurate. The leak also does not clarify whether the next model will be a point release like K3.1 or something larger.

Why Computer Use and Multimodal Improvements Make Sense

The direction toward computer use and multimodal capabilities is not surprising given Moonshot AI's existing product roadmap. The company has been building toward this combination for over a year through its Kimi Work desktop agent, which is available for macOS and Windows.

Kimi Work includes native computer use capabilities that allow the model to read screens and handle clicking, scrolling, and typing in the background without taking over your mouse. The system uses a browser bridge to drive real logged-in Chrome or Edge sessions over the DevTools protocol for navigation and form filling. Moonshot has also built Agent Swarm technology that can manage up to 300 parallel sub-agents, a goal mode that iterates on outcomes for hours, and a scheduler for recurring jobs.

The Kimi K3 model itself already supports native image input and was designed with long-horizon agentic work in mind. Moonshot's technical documentation describes training tasks that can run to thousands of tool calls while retaining file, application, and virtual-machine state. A successor explicitly weighted toward computer use would be the logical next step.

How to Evaluate Leaked AI Model Claims

• Verifiable Elements: Check whether claims about subscription reopenings, pricing changes, or API availability can be confirmed through official channels or user reports. The Kimi subscription reopening is verifiable and confirmed.
• Unverifiable Pipeline Claims: Post-training status and internal development timelines cannot be verified by anyone outside the company. A claim that "post-training has started" tells you roughly where a model sits in development but nothing about when it will actually launch.
• Date Predictions: Dates from leaks are the most testable claims anyone publishes. Track the source's accuracy on previous predictions before treating new dates as reliable.
• Missing Specifications: Be cautious of leaks that lack parameter counts, context length, pricing, licensing details, or benchmark scores. These details matter for understanding what the model actually is.

The current leak does not specify whether the next model will be called K3.1, K3.2, or K4, which represents three potentially different products. It also provides no information about model size, capabilities, or pricing.

What You Can Actually Use Right Now

The only confirmed product in this story is Kimi K3, the 2.8-trillion-parameter open-weight model that Moonshot shipped on July 16, 2026. This model is available now and supports native image input. The API access for Kimi was never part of the subscription pause and remains available separately from the consumer subscription tiers.

For users outside China, the subscription tier structure described above applies to domestic consumer plans. Regional pricing and availability may differ depending on where you are located. If you are interested in API access specifically, that product operates independently of the consumer subscription system.
