Moonshot AI has released Kimi K3, the world's first open model with 3 trillion parameters. According to benchmarks, K3 lags behind the closed-source Claude Fable 5 and GPT 5.6 Sol but is on par with GPT 5.5 and Opus 4.8. Pricing has increased two to three times compared to the previous K2.6, with input and output costs rising to $3.00 and $15.00 respectively.

Kimi K3 officially launches, but parameter count and compute constraints take center stage, with the official recommendation urging users to purchase Token Plans promptly.
On July 16, 2026, Kimi K3 officially launched. X user 歸藏 (guizang.ai) described it as 'quite impressive' in a post, hinting at strong performance. The post garnered approximately 9.9K views, drawing attention.
However, the post also noted 'tight parameter count and compute resources,' which may be a challenge for K3 or a concern for users.
Regarding the parameter and compute constraints, the only advice in the post is to 'buy Token Plan quickly.' This suggests Kimi may manage resource allocation through token plans, requiring users to purchase in advance to ensure usage.
This advice implies K3 may adopt a pay-per-use or resource quota model, requiring users to plan ahead based on their needs.
The information comes from X user 歸藏 (guizang.ai), a third-party source, not an official channel. Therefore, specific performance, parameters, and pricing of K3 still require official confirmation.
The post does not provide official links or detailed specifications, only a link to the Token Plan (not shown in the summary). Users should exercise caution and rely on official announcements.

Kimi K3 has launched, but parameter count and compute resources are tight. Users are advised to pay attention to official Token Plans for stable service.
