This is me
I ended up leaving OpenAI, not because there's anything wrong with OAI (I actually think they're underrated as a biz), but because to me, building commercial software doesn't feel fun anymore
Because agents write ~all the code:
- There’s less human to human collaboration, so it’s a lonelier experience
- You’re constantly context switching and not going as deep into the code, which means there’s ~zero flow state
- Most of the job becomes code review and trying to reduce complexity, which is very mentally draining
Again just my experience, and none of this specific to OAI. There are many people who seem to be enjoying building software in this era!
But I've always wanted to try making films, and now seems as good a time as any
New blog: Why does Kimi identify as Claude and Sonnet 4.6 as DeepSeek? We find that this can come from a subliminal-learning-like effect: If you speak like Claude, you become Claude.
For a finite set of integers (A), how much faster can (|A+A|) grow than (|A-A|)?
A 1969 theorem gave an upper bound of 2 for the exponent. For more than 50 years, the best constructions barely exceeded 1.1.
With help from our research agent Hyra and the Hy3 model, we found an explicit construction showing that the optimal exponent is exactly 2.
A 50-year-old problem, solved.

Releasing the model weights and technical report of Kimi K3.
Kimi K3 is our most capable model: a 2.8T MoE model with native visual understanding and a 1M-token context window.
New model architecture: 2.5x the intelligence per unit of compute, not just more params.
Alongside Kimi K3, we're opening up more of the stack behind it — high-performance attention kernels, MoE communication library, and infrastructure for running agent environments at scale.

For my first post, I’m sharing a letter @NVIDIA signed on why open models matter.
AI will transform every industry, power every company, and be built by every country.
Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty.
The world needs both frontier closed models and frontier open models.
