The claim hinges entirely on the narrow definition of "large-scale energy generation." For the UK, with its high seasonal energy demand and low winter solar output, the cost of generation is almost irrelevant next to the cost of firming that power for 24/7/365 availability. While the paper[1] shows solar PV and daily-cycle batteries are getting cheaper, it also shows seasonal storage solutions like hydrogen are still an order of magnitude too expensive and inefficient (huge capex for electrolyzers/storage + poor round-trip efficiency). So providing reliable, 24/7/365 baseload power from PV + storage in the UK is demonstrably not cheaper than gas or nuclear today.

> At the time of writing, the highest-ranking non-purely-transformer-based model on the LM Arena is Jamba, which is a transformer–state space model hybrid, at rank 96.)

Tencent's hunyuan-turbos, another hybrid, is currently ranked at 22. https://arxiv.org/abs/2505.15431

From the paper, section 2.1: minimize_θ,φ,Δ ||P_φ(Δ, E_θ(x)) - sg(E_θ'(y))||_1

where

y - full video, x - masked video, E_θ(.) - learned encoder (semantic embedding), P_φ(.) - learned predictor, Δ - learned mask (which patches in a video where dropped), sg(.) - stop gradient to prevent change, gradient propagation in E_θ'(.), which in turn is an exponential moving average of E_θ(.) ie. θ'_new <- τ θ'_old + (1-τ) θ. So the loss is applied only to the predictions of the masked patches while the encoder of full video follows the learned one. This asymmetry in learning prevents collapse of the encoder to a trivial constant.

It seems like a model is not included; you need to set an API endpoint in a configuration https://tmuxai.dev/getting-started#environment-variables

I was thinking, to build a large, efficient factory autonomously, one could use LLM as a high level agent that is using specialized tools. The overall strategy would perhaps look like following:

1. create a (intermittent) goal for a resource production

2. create a factory graph with calculated number of machines and number of resources required to transport between them. This would be done by using linear programming (factorio calculator)

3. somehow map the resulting graph to a hardware description language. Such that each entity would be mapped to unique logic component. And each transport lane would be mapped to a unique wire (most difficult)

4. compile to 2d FPGA layout using all the VLSI algos like partitioning, routing (hdl compiler)

5. map the resulting plan back to a concrete factorio design

This doesn't apply to energy grid scale projects. Also that is why energy sector in most countries is privatized. Take Germany with total energy costs that would be like ~10% of the federal budget (about 40 billion euros). Making energy even more expensive would only lead to further deindustrialization and lower gdp making it politically non viable. Also, you can't just throw money and buy storage like with typical government contracts - it requires building entire new industries (like Germany's struggles with hydrogen infrastructure).

none of those storage solutions are easy for grid scale. For batteries you need whole factories, pumped requires permits and tone of cement, chemical is like hydrogen with low efficiency. All of those are expensive which for government is synonymous with difficult.

pumped hydroelectric is storage; right now it is like 99% of world storage capacity.

Solar PV operates 10-30% of the time (depending on location). Without storage, this naturally limits direct solar contribution to about 20% of energy demand. Going beyond requires expensive storage solutions.

Achieving the first 20% of solar in an energy mix is relatively easy. Beyond that costs increase 3-5 times per energy unit mainly due to storage.

How does it compare with xenotransfusion from genetically modified pigs?

I guess the extended shelf life and more compatibility might be some of the pros of synthetic blood.

According to https://www.metaculus.com/questions/14270/spacex-starship-or... its chances to reach orbit in 2023 have just risen from 85% to 90%. Therefore generally I would call the launch a relative success.

Yes; metaculus is reputation based. Though in the comment section you will find links to other markets like https://polymarket.com/event/will-erdogan-win-the-2023-turki... which is money based market.

In my opinion the biggest near term danger is that AI will make people overly trust it. And they will start treating it as a truth oracle. Oracle that will be controlled by some small group of people. Namely, it will become a perfect tool for propaganda and control.
