kuprel··on Fly Around the Bay Area at Mach 10 with an Apple Vision Pro, Built with Astra
Nod head to change jet's pitch, tilt head to bank the jet. Pinch to fire a missile. Pinch and hold to throttle the aircraft. I've only tried on AVP2, not AVP1
kuprel··on Claude Fable 5
https://artificialanalysis.ai/evaluations/humanitys-last-exa... Not bad
kuprel··on DARPA's new X-76
From the image it doesn't look balanced for VTOL when the propellors are vertical. Also are the jets enabled during VTOL?
kuprel··on Gemini 3.1 Pro
GPT 5.2 loses at everything but they included that
kuprel··on Gemini 3.1 Pro
Why don't they show Grok benchmarks?
kuprel··on ./HelpGod
Sounds scary haha
kuprel··on God Simulator in Bash
A simulation of God's decision tree for the Serenity Prayer: "God, grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference."
kuprel··on New research reveals the strongest solar event ever detected, in 12350 BC
This was my first thought. It seems this solar event happened over 1000 years before Younger Dryas
kuprel··on OpenAI Audio Models
They released a crippled model: https://github.com/SesameAILabs/csm/issues/63
kuprel··on OpenAI Audio Models
OpenAI doesn’t have voice cloning
kuprel··on DeepSeek-R1: Incentivizing Reasoning Capability in LLMs via RL
I wonder if a language model can be treated as a policy over token-level actions instead of full response actions. Then each response from the language model is a full rollout of the policy. In math and coding, the reward for the response can be evaluated. This is not how DeepSeek works now, right? It treats full responses from the language model as the action if I understand correctly.
kuprel··on Llama 3.1 405B now runs at 969 tokens/s on Cerebras Inference
I wonder if Cerebras could generate video decent quality in real time
kuprel··on 1 in 4 U.S. Teachers Say AI Tools Do More Harm Than Good in K-12 Education
So then 3 in 4 say AI tools do more good than harm?
kuprel··on Egypt's pyramids may have been built on a long-lost branch of the Nile
What if they’re even older than 11.5ky? Neanderthals had larger brains and have been around for half a million years
kuprel··on Egypt's pyramids may have been built on a long-lost branch of the Nile
So maybe the pyramids are older than we thought?
kuprel··on 55x Speedup of Andrej Karpathy's Minbpe LLM Tokenizer with PyTorch/CUDA
Using int16 and an H100 the speedup is actually 108x over the M2 air
kuprel··on 55x Speedup of Andrej Karpathy's Minbpe LLM Tokenizer with PyTorch/CUDA
The M2 Air was actually much faster than whatever CPU was on the cloud RTX4090 machine I rented. I chose the stronger benchmark to compare to
kuprel··on 55x Speedup of Andrej Karpathy's Minbpe LLM Tokenizer with PyTorch/CUDA
This adds PyTorch/CUDA training support to Andrej Karpathy's minbpe. It takes 2min 28sec (148 seconds) on an RTX4090 to train the BasicTokenizer with a vocab_size of 512 on 307MB of Enron emails. The original code takes 2hrs 15min (8076 seconds) on an M2 Air with Python 3.11 to do this. That is a 55x speedup.
kuprel··on Sora: Creating video from text
chips will have to come a long way for this to be generated in real time, but there's no reason a generated 3D environment can't be interactive
kuprel··on Sora: Creating video from text
Next they have to add audio, then VideoChatGPT is possible
kuprel··on Observation of zero resistance above 100 K in Pb₁₀₋ₓCuₓ(PO₄)₆O
Why don't they just share the original sample? At least it could offer an existence proof
kuprel··on Ice core scientists in East Greenland reach bedrock
I didn't realize that the vast majority of the time Earth is in an ice age. What causes it periodically like this?
kuprel··on LLaMA2 Chat 70B outperformed ChatGPT
Was LLaMA2 potentially trained on the raw text from this page? https://huggingface.co/datasets/tatsu-lab/alpaca_eval/viewer...
kuprel··on Artificial brains help understand real brains
The left hand in that photo should be a humanoid robot hand. Didn’t actually read the article
kuprel··on Scientists warned about climate change in 1965
When I was growing up the concern was that fossil fuels were a limited resource that we are rapidly depleting. Now the concern is that they are far too abundant and cheap for our own good. Eventually the economics should force us to use renewables if the fossil fuels are a rapidly depleting limited resource, right?
kuprel··on Direct air capture: our technology to capture CO₂
The entire aviation industry emitted 619 million tons of CO2 in 2019 [1]. So about 155 thousand of these plants would be needed just to offset air travel

kuprel··on Comb jellies are the closest relatives of the first animals
I found this quote interesting:

> Recent discoveries have shown that ctenophores have no synapses, the tiny connections between neurons. Instead the cells of their primitive nervous system, known as a nerve net, are fused together, forming a syncytium—“an entirely new way to build a nervous system”

It makes sense that synapses would be more general/powerful than fused neurons. Different neurons can connect over time with synapses

kuprel··on RNA repair mechanism discovered in humans
We build things with factories where the factory is orders of magnitude more complicated than the thing being built. Life build things via self replication at a microscopic level. Seems like a fundamentally different approach
kuprel··on Gordon Moore has died
Long live Moore's law
kuprel··on A 'subterranean Galapagos' inside the Earth (2018)
Wonder if there’s a pocket of advanced life (e.g. mammals) we haven’t discovered yet
