Moonshot AI

Kimi K3.1 Pro has a 1-million-token context window and a Highspeed variant that runs 2-3 times faster. On Artificial Analysis's index it scores 55, fourth overall, while using 150M tokens against a median of 87M.

Moonshot also says it deliberately kept the open weights below its own pipeline's offensive-cyber capability.

The US government's chief technology officer tweeted that China's Moonshot AI illegally distilled Anthropic's Fable model to build Kimi K3 — released just three weeks after Fable itself went public.

The thread ran the timeline: Fable's access limits lifted July 1, K3 shipped July 16. Commenters found the compressed window less like theft, more like a stretch. One AI-lab-adjacent voice called it "BS to pressure politicians"; HN's own moderator waded in to police the discourse rather than settle the science.

A security researcher: distillation is real, but doesn't require the drama — "99% of the work is already done by that point."

The pitch includes a Cron engine for scheduled overnight runs, an "agent swarm" that splits work across sub-agents, and pre-wired financial data feeds for US, Hong Kong and mainland stocks. It ships only for Windows and Mac.

The line "Let's take something off your plate" turned out to be lifted straight from Claude Cowork's own hero image. A commenter who says he builds LLM systems for a living found a bigger problem: the privacy page promises consent before Kimi touches your files, but never mentions it already reads them without asking.

Ben Thompson's essay argues Chinese AI panic is overblown: Moonshot's Kimi K3 prices tokens at $3/$15 per million against a frontier rival's $5/$30, evidence he reads as intelligence turning into a plain commodity, not a security crisis.

One reader who benchmarked roughly 50 models for a real production system found the opposite: frontier models were far more token-efficient than open-weight ones, even scoring worse on raw accuracy — the number Thompson's argument never cites.
