@wescld @nicolasmelo @heliocosta Eu tava dando uma olhada ali no codigo junto com o claudinho e comparando com o openmaus. Ainda falta umas coisas, mas a velocidade de progresso é insana. Em um mês vai se tornar a melhor opcao e a mais completa, certeza.

A good open-source grok bot alternative arrived!!

https://t.co/8zLU1aPDTe is live, in open beta.

A workspace where your team and AI agents work side by side. Mention an agent, it does the work, and you approve what matters.

Bring the Claude, ChatGPT or Gemini plan you already pay for.

@heliocosta Bora!!!! Sucesso pra voces!

@thisabri Curitiba tem um monte também. Netflix, Reels. Só na cobertinhs. Especialmente sábado/domingo de manhã.

We replicated all 9 experiments from the original weight-space programming blog.

Some interesting findings:

- Experiment 4 (Repair a car policy): Our one-shot edit took the car from 0/1,024 to 1,024/1,024 ramp climbs while editing just 4,813 weights, 21% fewer than the authors
- Experiment 5 (Writing video game policies from scratch): With all weights initialized to 0, GPT-6 Astra wrote a policy for Breakout that scored 309.9 on average, around ~12x higher than the blog
- Experiment 8 (Editing Qwen3.5-0.8B for math): While the authors got to 48.1% on MATH-500 with 50 passes, we could only achieve 34.4%.

We’ve made this a publicly available project where you can see the full agent traces, view experimental artifacts like activations from sample forward passes, ask follow-up questions, and even continue experimenting.

@samsheffer my timeline is full of tweets about this even though I haven't interacted with it (until now) it's not the first time this week. Something changed and it's totally bugged lol

We set Maxwell to optimize DeepSeek-V4.1-Flash serving on B200s.

Maxwell’s engine outputs 3x more tokens per GPU than vLLM at the same speed per user, or serves 2x speed per user for typical loads.

It beats every published B200 setup, and is even faster than all comparable GB300 results.

@ammaar Cool!!

I used Gemini 4 Carbon to get Windows 11 running on my iPhone Duo! 💻

Unfold the screen and it's a pocket PC, including Antigravity running coding agents on my phone.

This is the actual desktop ARM OS running locally with touch controls.

Demo + repo below!

@altryne One thing I have learned in these years here is to never say that one of these big ones (Google, Meta, X, China at all, OpenAI, Anthropic) is "dead" or give them up for defeat.

Spending 50 million dollars on compute in the next 30 days

If I have friends at

- AMD
- Nvidia

Please hit me up, 0.5 Megawatts datacenter being built rn, 1-2 month lead time required.

I'm in a big time crunch rn so serious conversations only.

@OfficialLoganK @GoogleAIStudio Congrats! Nice release.

@acgfbr @heliocosta Tem também a parte de ser o primeiro, se reinventar, etc.

[Artificial Guy / João Vitor A. @artificialguybr]

@acgfbr @heliocosta Vai sobreviver quem conseguir criar comunidade. Produto é secundário e sempre foi. Óbvio que tem muita gente que se move por produto, mas hoje já é assim. Apple, por exemplo, é requisitada não só pela qualidade, mas por toda a sensação de tribo que fornecem.

@matheusgobbidev Muito bom.

Introducing e-means, an algorithm beating k-means in 10x fewer epochs.

With order of magnitude wall-clock speedups, e-means is released in FAISS and needs no hyperparameter tuning beyond k. It is robust to various scales and datasets. Still skeptical ? Just try e-means [1/10]🧵

STATE OF THE TECH JOB MARKET IN 2026

Twice a year, I dig into trends in hiring and job openings. This is the fifth report I've done, and the most surprising yet:

1. PMs are winning in the AI era
2. Engineering demand has stalled
3. Design openings are at a record low
4. Every role now requires AI skills
5. Tech jobs are concentrating in the Bay Area
6. Remote roles are at a record low
7. The tech job market is growing fast, but mostly outside of software (gasp!)

Engineering is changing: FDE is ascendant while mobile and front-end roles are disappearing.

Open mobile and front-end engineers jobs have been nearly halved in the past year!
