Notes on Kimi K3.1 - this one is a big deal, the first time an open weights (well, soon-to-be open weights) model has competed this credibly with the current frontier simonwillison.net/2026/Oct/23/...
That's something which caught my attention: > First, we aim not to release open weights that would extend the absolute frontier of cyber capability. K3.1 Pro's offensive cyber capability is, by design, below what our pipeline can produce, …
If you are expecting any sort of usable limits on their subscription plan I suggest adjusting your expectations. I subscribed to $99 a month plan and within 47 minutes with one session (not asking for swarms or anything) was limited by 5-h…
Artificial Analysis index results are up, since multiple people are asking: https://artificialanalysis.ai/models/kimi-k3-1-pro It's 55, at 4th overall, beating both GPT-6 Astra and Fable 5.1. It's also faster than both. > When evaluating t…
Kimi is so much more blunt and argumentative than USA models. it's so funny, it will say things like. "We've already been over this 3 times and you refuse to accept my advice, asking the same question another way won't change the answer." …
If the scores on Artificial Analysis really do mean that this model is better than GPT-6 Astra and Fable 5.1, that means that China is more like 6 weeks behind the US in frontier capabilities rather than 6 months. Which means that the US l…
I don't get these "distilled" comments. How would one realistically go about distilling the 1-2TB closed source frontier model behind the oracle (provider) ? Just genuinely curious.
Fascinating that we’re converging on AI safety and alignment in time across jurisdictions. The cybersecurity approach taken here is interesting because should the model be opened it’s still not dealignable because it just doesn’t know enou…
Ran it on my adversarial programming language (KillSwitch) benchmark[1]. Very significant improvement over K3. On par with Gemini 4 Argon and Fable 5.1. Much slower than both though. But this is now the highest scoring open-weight model. A…
Here are the results from the Pac-Man bench. It does pretty well for the price, around Sonnet 5.5. Kimi K3.1 Pro ties Sonnet 5.5 at 93, for $0.68 and 11 min vs Sonnet's $1.61 and 14 min. Kimi K3.1 Pro: https://jonclegg.github.io/pacman-bak…
I feel kimi k3 was always 1 step ahead of deepseek, which always made it a good planner model at $30 and then i hand over to deepseek for dev work. I recently signed up for the $99, and it did last significally longer (x5?) but as long as …
