Does your Claude model really need Claude Code…? 🤔 We evaluate 7 models on Claude Code, Codex, and Pi. Three surprising findings emerge: 1️⃣Harness choice has little effect on task success rate, but can significantly affect the cost 2️⃣A simple harness can be competitive 3️⃣The native harness isn’t always the best. Millions of people are using coding agents, but the impact of harness choice remains unclear. (1/n) More details in the thread. 🧵

𝗪𝗛𝗔𝗧 𝗜𝗙 𝗧𝗛𝗘 𝗔𝗜 𝗝𝗢𝗕 𝗗𝗢𝗢𝗠𝗘𝗥𝗦 𝗔𝗥𝗘 𝗪𝗥𝗢𝗡𝗚? In January at Davos, we were told AI could do "most, maybe all" of what software engineers do within 6 to 12 months. My feed filled up with "developers are cooked." 😱 Eight months later, here's what the data shows: ✅ US software developer job postings are up ~15% since February 2025, while overall US postings fell 7% (Indeed Hiring Lab) ✅ A Federal Reserve paper found more people held software developer jobs in 2026 than in 2025 ✅ In the recent rebound, the most AI-exposed occupations recovered the most ✅ BLS still projects 15% growth for software developer jobs through 2034 The jobpocalypse crowd got this badly wrong. So far, AI looks far more like a tool that expands what companies build than one that replaces the people building it. To be fair, it's not all good news. Developer postings are still ~27% below pre-pandemic levels, and 71% of the recent growth went to senior roles. Juniors are having a genuinely hard time. But that slump started with the 2022 overhiring bust, before ChatGPT even existed. Bold predictions move headlines and markets. Data moves slower, and right now it's telling a very different story. Stop panicking. Keep building. AI is not going to replace you is a tool to improve your productivity.

This September, we're building at @dhworkspaces Picoas. A space made for exactly this kind of day: room to spread out, focus, and work alongside 100 other builders shipping real AI projects. September 25, Lisbon, during @lisbonaiweek.

Choosing an AI model is no longer just about picking the one at the top of a benchmark. @heldervasc breaks down how to actually choose the right AI model, at The Collider on October 15. Save your spot. 👇 luma.com/qlvrf8sl

There are two AGI scoreboards. One is capability, where the frontier still leads. The other is cost per task, where open weights now win by up to 50x. Picking a model is the wrong move. The fix is a routing policy: cheap-to-be-wrong calls go to self-hosted open weights, expensive-to-be-wrong calls go to the frontier. @heldervasc breaks down why.

It is August and I have lost count of the frontier releases this year. I sat down to pick the one we should standardise on. Never got an answer. Got a better question. Model choice is a routing policy now, and it is yours to build hvasc.dev/articles/agi-two-s…

What does a day of building with AI actually look like? We put it on camera. From first-timers to seasoned devs, we asked people at AI Hacker House: Solstice Edition what brought them to Porto, and @hypermarioal shared why LayerX put this together in the first place. Hosted at @dhworkspaces Península, with prizes powered by @YLDio and @supabase, and Sumol Compal, Pleno, Vital Shot, Padaria Formosa, Braza and RHEA Therapies keeping everyone fed, hydrated and relaxed. Thanks also to @lisbonaiweek, @TalentProtocol and Innovation X Hub for helping spread the word. Watch the recap below. ⬇️

Na LayerX, todas as semanas falamos com empresas que querem implementar e escalar IA. O bloqueio nunca é o modelo, é a governance. Escrevi um artigo um artigo sobre a camada de software que falta entre a IA e os dados da empresa 👇
Article

O problema da IA nas empresas não é o modelo. É a governance.

Não há adoção de IA à escala sem governance. E não há governance sem infraestrutura resiliente, segura e auditável. Na LayerX falamos com empresas todas as semanas e o problema é sempre o mesmo. Não é

wen @Kimi_Moonshot k3 on the board @ickasdev ???
We sent two @AnthropicAI models to TAIKAI AI Arena. Both came back with medals. 🏅 Fable 5 won decisively with best repo, best demo, best write-up. Opus 4.8 came in second. The only surprise in the top 3 was Kimi K2, which matched them on both scoreboards for $3.11. The winner spent $68.73. Same podium, 22x the price.

Estou a contratar o meu braço direito nas vendas de AI Consulting da @LayerXlab . Drive e agência acima de currículo. Savvy em IA. Português e inglês. Não é estratégia. É falar com empresas, perceber onde a IA resolve um problema real, e vender isso. Não envies currículo. Instruções no primeiro comentário.

Um truque na interface do Amália: cada conversa fica presa a um backend específico, via hash do id da conversa. Porquê? A cada mensagem, o modelo reprocessa todo o histórico da conversa, e esse trabalho fica guardado no KV cache, a memória de curto prazo do modelo. Se a conversa voltar sempre à mesma máquina, o cache já está quente e só se processa a mensagem nova. Com round-robin, pagava-se o histórico completo de cada vez. Bónus: para dar mais peso a uma máquina mais rápida, basta repetir o URL dela na lista de backends.

We spent a day at CEiiA and left with proof that you don't need to be a developer to ship production tools. Just the right problem and the will to solve it. Not prototypes, but things people are already using. Thanks to Leandro Leite and the whole CEiiA team for making it happen. Looking forward to see what's next! 🙌
