MACHINES: A HISTORY OF ELECTRONIC MUSIC - OUT NOW!
I'm delighted to share that my new book is out now in the UK and Australia, with more countries to follow.
A journey through the instruments, sounds and stories that shaped electronic music.
Order now: lnk.to/MachinesJean-MichelJa…

History will show that no one did more to promote left-wing ideas than Donald Trump, and no one did more to advance the Palestinian cause than Benjamin Netanyahu.

Antiguidade (77 d.C.): O escritor romano Plínio, o Velho, escreveu na obra História Natural: “Quando um prédio está prestes a cair, todos os ratos o abandonam”.
Não vai ter o tokenpocalypse
Essa é outra noção que passou. 2 anos atrás a gente falava em subsídio de tokens. Mas de lá pra cá otimizamos MUITA coisa, desde quantização, MoE, KV cache, prefix/prompt cache, MQA/GQA/MLA, PagedAttention/FlashAttention, chunked prefill, speculative decoding, etc etc
Parece que inteligência nível GPT-4 caiu da faixa de USD 37/mi de tokens pra USD 0.10 agora. Chequem o BenchLM Token Price Index e Brief Script AI Price Index.
Topo dos modelos da OpenAI: GPT-4 era 37.50, GPT-4o foi pra 7.50, GPT-5 foi pra 3.44.
Entendam, já conseguimos rodar bons modelos em 32GB VRAM (importante é a banda, não a qtde de memória).
Eu chutaria que hoje não tem mais subsídio e na verdade alguns cobram mais caro (por conta de sticky prices).
Powerpoint was instrumental in enabling semi-articulate corporate zombies to pretend they had well... a point. AI is another big step in cognition emulation for the corporate ladders
Sure you can get a Yolo family and other classic neural network trained on ImageNet or COCO from 10 years ago capable of being trained to identify up to a few 1000s of types of objects
The news here is learning in real time a decently performative model.
When I said hunch could learn in real-time I wasn't kidding. It's like teaching a kid!
Behind the scenes, @Cloudflare’s Clef is helping refine the local model so it learns in real time, while @googlegemma’s EmbeddingGemma2 runs live on the CPU. 🧵
Small AI news part 2 - decision models
It's been a while since I showed any Jev stuff but I've been cooking on a way to use @GoogleDeepMind's EmbeddingGemma2 as an insanely fast real-time /v1/systemone endpoint (20ms on text, 100ms on images).
It's trainable in real-time, can distill an upstream teacher model, and is multi-modal by default. Hard to believe a @googlegemma model of this size can do so well with the right harness!
OCR has been having insane evolution. How long ago was Deepseek OCR? A year?
Oh my. Best open OCR model by a mile.
... and Baidu took the KV cache for hundred-page OCR from 47GB → 1.77GB.
Unlimited OCR 2 is only ~3.3B parameters and it's designed to parse documents 100's of pages long without memory and decode latency growing as the document gets bigger.
The secret sauce is SR-SWA.
Instead of every new token repeatedly attending across an ever-growing document, it keeps a fixed-size set of useful text/visual references.
According to Baidu ...
🧠 Peak KV cache → 47.0GB → 1.77GB
📉 ~96% reduction
⚡ per-step decode → up to 7× faster
🚀 16-doc throughput → 360 → 1,315 tps 👈👀
Now look at Baidu's 100–300-page benchmark MarathonDocBench:
Unlimited OCR 2 → 77.1
Kimi-K3 → 33.7
Gemini 3.8 Flash → 28.6
Qwen3.8-Max → 22.9
Of course, this is vendor-reported, so independent reproduction matters.
Baidu also reports that shorter documents get even more accurate
Unlimited OCR 2 → 84.6
Qwen3.8-Max → 78.3

Can we squeeze this onto a 16GB GPU?

É exatamente isso. Tarcísio não gabaritou o código penal e poderia ter levado no 1.o turno
If Flávio loses, Jair Bolsonaro’s decision to back his son over Tarcísio de Freitas will be widely seen as a decisive error. Many on the right will argue that Tarcísio, who polled better against Lula and was the centrão’s favorite, would have had a better shot. Jair, aware of his son’s weaknesses, chose to keep power in the family.
Enquanto essa ficha não cair o antipetismo vai continuar perdendo

Google can afford to play the long game. The Cinderellas have a ticking clock
Really looking forward to knowing the thermal implications on this one
Modders have unlocked hidden AI compute performance on NVIDIA’s RTX 20, 30 and 40-series GPUs.
The modifications remove software-level limits on certain Tensor Core operations, without changing the hardware or flashing a new VBIOS.
- RTX 4090: 165.6 → 331.6 TFLOPS FP16 Tensor Core throughput
-RTX 3090 Ti: 87.5 → 157.4 TFLOPS BF16 performance
- RTX 2080 Ti: 59.9 → 111 TFLOPS FP16→FP32 performance
- RTX 3090: 73.0 → 122.8 TFLOPS in a PyTorch GEMM test
The gains are mainly relevant to AI and compute workloads, not gaming.
