👉 Get AI Agents to Do Work For You: https://skool.com/aimate I did not expect a model I'd barely heard of to be sitting on top of Claude this week — so I went and read the whole thing, and there are five parts of this I still can't get over. Kimi K3 just landed at number one on the Frontend Code Arena with a score of 1,679 — above Claude Fable 5, above GPT-5.6 Sol, above Claude Opus 4.8. It's from Moonshot AI, a company founded in March 2023 by three schoolmates from Tsinghua, and the whole thing is open source. In this video I go through Moonshot's own announcement and the real leaderboard, and break down the five things that actually shocked me. The jump from #18 to #1 in a single release. What they call "the largest open-weight AI system ever built" — 2.8 trillion parameters, a one-million-token context window, weights you can download and keep instead of rent. The pricing: $3 per million input tokens, $15 out, and a full frontier reasoning run for 25 cents. Kimi Delta Attention, the architecture trick behind up to 6.3x faster decoding — the actual answer to how a small team competes with OpenAI's budget. I'm also honest about the part most of the coverage skips: this #1 is the Frontend Code Arena specifically. On the broader benchmarks, Fable 5 and GPT-5.6 still lead. That's the real story — an open model you can download for free is now trading punches with the giants. Stay to the end for what this actually means if you're running AI agents inside a business. ____ 00:00 // Intro 00:45 // #1 — It topped the Frontend Code Arena 02:41 // #2 — "The largest open-weight AI system ever built" 03:59 // #3 — Frontier power, budget price, and how to actually get it 05:42 // #4 — The clever trick: Kimi Delta Attention 07:37 // #5 — Three founders, three years, punching at OpenAI 08:55 // What this means if you run agents in your business 10:23 // Outro ____ Click Here to Start AI Automation: https://skool.com/aimate/about Follow me on Twitter: https://twitter.com/itsaiandy Follow on Tiktok: https://www.tiktok.com/@andyhafell Follow on Instagram: https://www.instagram.com/itsaiandy Follow on Facebook: https://www.facebook.com/Andyhafell Email for Business Inquiries: biz@aiandy.ai
