Before everybody get's too excited about available Chinese open weights models, the infrastructure costs for running these models are immense, it's hard to find specific and reliable data but think about half a million dollars of infrastructure costs for 5-15 users according to this linkedin post.

Kimi K3 just dropped. 2.8 trillion parameters, 1M-token context window, open weights. Capabilities comparable to Fable 5. 🔥 And every enterprise buyer is doing the same math right now. Here is what running it yourself actually costs: - 16x NVIDIA H200 GPUs: ~$500,000. That's GPUs only. No chassis, no networking, no power infrastructure. - Model weights on disk: 1 to 1.7TB depending on quantization. - What's left for actual context: somewhere between 550 and 1,250GB of KV cache.

Anthropic has been trying to understand how large language models (LLMs) work for a few years now.
Anthropic isn’t the only one looking at this, but I think the company has made it part of its core mission more than most.
Anthropic’s CEO, Dario Amodei, has said we won’t be able to control LLMs fully unless we learn more about how they work. 
So this new research is very much in that context.
It goes deeper into the weird mechanisms inside LLMs than ever before.

What Anthropic’s latest AI discovery does—and doesn’t—show
The company says it has found a new window into how its models arrive at answers. We spoke with senior editor Will Douglas Heaven about it.

Discovering Functionally Selective Brain Regions with a Deep Topographic Multimodal Model
Nearby neurons in cortex share similar response profiles, producing systematic spatial organization across sensory and cognitive systems. Recent topographic models reproduce aspects of this structure but remain unimodal and spatially constrain each layer separately, yielding fragmented maps that capture neither the contiguity of cortical processing streams nor their integration across modalities. We introduce Topo-Omni, a topographic multimodal model in which visual, auditory, and language/cogn…

Abstract: Thermodynamic nonequilibrium effects play a central role in momentum and energy transport in compressible flows. In conventional BGK kinetic models, the relaxation time $\tau$ is taken as a constant, which neglects the dependence of the relaxation process on local macroscopic states. To overcome this limitation, we develop a discrete Boltzmann model with a density- and temperature-dependent power-law relaxation time, termed DTRT-DBM, in which $\tau=\tau_0(\rho/\rho_0)^a(T/T_0)^b$. This formulation extends the discrete Boltzmann framework to flows with spatially varying nonequilibrium intensity. The model is validated by the Sod shock tube and by analytical solutions for viscous stress and heat flux, demonstrating accurate recovery of both macroscopic wave structures and nonequilibrium quantities across shock waves, rarefaction waves, and contact discontinuities. On this basis, phase diagrams of viscous stress and heat flux are constructed to examine how these quantities depend on the power-law exponents $a$ and $b$. The extrema of these quantities depend exponentially on the model parameters and exhibit regime-dependent behaviour. The roles of $a$ and $b$ are not symmetric: the nonequilibrium response is more sensitive to $a$ when density gradients dominate, but more sensitive to $b$ when temperature gradients dominate. Within the parameter range and flow configurations examined here, higher-order viscous stress increases the growth rate of the total viscous-stress extremum, whereas higher-order heat flux reduces the growth rate of the total heat-flux extremum. These results show that the proposed model can capture different higher-order nonequilibrium responses in compressible flows and provides a framework for the modelling and analysis of multiscale nonequilibrium processes.

Strikes early Wednesday destroyed what appears to be a drinking-water facility on Iran’s southern coast, near the Strait of Hormuz, according to an analysis by The New York Times.
Around the time of the strikes, the U.S. Central Command said in a post on X that it had conducted attacks near the strait “with precision munitions from U.S. Air Force and Navy fighter jets.”
It is unclear if the U.S. intentionally struck the water facilities, or knew what was in the buildings.

It is unclear if the U.S. intentionally struck the facility or knew what it was. Deliberately targeting civilian infrastructure could constitute a war crime.
