Moonshot AI's Kimi K3.1 Leaked with 3D Code Focus
Moonshot AI's Kimi K3.1 model leaked with 3D code generation capabilities, raising pricing and regulatory questions.
In brief
Moonshot AI's Kimi K3.1 model leaked with 3D code generation capabilities, raising pricing and regulatory questions. Moonshot AI's Kimi K3.1 model, reportedly with 3D code generation, faces pricing challenges and China's export controls on large models. Originally reported by BigGo Finance.
Kimi K3.1 Leaked
Moonshot AI released a 24-second teaser video on October 23 confirming the model identifier as Kimi K3.1.
“Moonshot AI released a 24-second teaser video on October 23, in which the model identifier on screen reads Kimi K3.1”
Kibitz Model Emerges
An anonymous model named Kibitz landed on Arena on October 22, matching Kimi K3's patterns.
“An anonymous model named Kibitz quietly landed on the model leaderboard Arena”
3D Code Performance
Kibitz generated 3D courtyard and helicopter scenes faster than GPT-6 Astra Max.
“Kibitz delivered a richly layered, colorful result, while GPT-6 Astra Max completed the task too but took roughly three times as long”
Tokenizer Tests
Kibitz shows Moonshot family tokenizer patterns with two errors on token strings.
“When asked to reproduce verbatim 11 special token strings characteristic of the Moonshot family, Kibitz erred on two consecutive rounds”
Kibitz Naming Pattern
Kibitz fits Moonshot's naming sequence: Kimi K2.5, K2.6, K3, K3.1.
“Kimi K2.5, K2.6 and K3 were previously tested under the codenames Kiwido, Kiwire and Kivine respectively”
Arena Code Tests
Kibitz created interactive pelican webpage and 3D helicopter in under 15 minutes.
“The classic "pelican riding a bicycle" SVG prompt was turned into an interactive webpage where users can adjust pedaling frequency”
Kimi Code Configuration
Kimi Code configuration showed 'k3.1' before a 404 error on October 21.
“On October 21, a developer found the string "k3.1" appearing directly in Kimi Code's configuration”
Front-End Code Leaks
Official website code revealed 'make3d' and 'k3d1-agent' for 3D and multi-agent tasks.
“Identifiers including k3d1-agent, make3d, AUTOMATION_K3 and OK_COMPUTER_SWARM were dug out of the official website's front-end code”
SGLang Commit
SGLang reported K3.1 reuses K3's tokenizer with a 'medium' reasoning tier.
“A code commit titled "Kimi-K3.1 support for the K3 chat encoder" appeared in SGLang's GitHub repository”
K3.1 Pricing Challenge
K3.1 faces pricing pressure as overseas vendors cut API costs to $2-$10 per million tokens.
“Claude Opus 5.5's input and output prices have fallen to $4 and $20 per million tokens”
China's Export Controls
China's Ministry of Commerce and Science Technology proposed export controls for large models over 2 trillion parameters.
“On October 16, China's Ministry of Commerce and Ministry of Science and Technology issued Announcement No. 48 of 2026”
K3 Parameter Threshold
K3's 2.8 trillion parameters exceed China's export control threshold but are in public domain.
“K3's 2.8 trillion parameters already exceed the threshold, but its weights were published long ago”
K3.1 Release Uncertainty
K3.1's open-weight status depends on China's export control finalization.
“If the decision on whether to open-source it comes only after the catalog is finalized, open weights will no longer be purely a product decision”
3D Focus for K3.1
K3.1 likely prioritizes 3D code generation and multi-agent collaboration features.
“Judging from the official teaser video's direct showcase of Three.js 3D scenes, 3D creation is likely to be one of the focal points”
The takeaway
Moonshot AI's Kimi K3.1 model, reportedly with 3D code generation, faces pricing challenges and China's export controls on large models.
