If you love fine-tuning open-source models (like me), then listen.

> Start with 1B, 2B, 4B, and 8B models. (Don't start with a 27B model or bigger at first.)

> Use WebGPU providers. I use Google Colab Pro for any model smaller than 9B. A single A100 80GB costs around $0.60/hr, which is cheap. Enough for small models.

> Don’t buy GPUs unless you fine-tune 7 to 10 models. You'll understand the nitty-gritty in the process.

> Use Codex 5.5 × DeepSeek v4 Pro to create datasets. Codex to plan, DeepSeek v4 Pro to generate rows.

> Use Unsloth's instruct models as a base from Hugging Face. Yes, there are others too, but Unsloth also provides fast fine-tuning notebooks.

> Use Unsloth's fine-tuning notebooks as a reference. Paste them into Codex, and Codex will write a custom notebook with the configs you need.

> Spend 1 day learning about:
- SFT (supervised fine-tuning)
- RL training (GRPO, DPO, PPO, etc.)
- LoRA / QLoRA training
- Quantization and types
- Local inference engines (llama.cpp)
- KV cache and prompt cache

> Just get started. Claude, Codex, and ChatGPT can design a step-by-step plan for how you can fine-tune your first AI model.

Future tech is moving toward small 5B to 15B ELMs (Expert Language Models) rather than general 1T LLMs.

So fine-tuning is an important skill that anyone can acquire today.

Tune models, test them, use them. Then fine-tune for companies and make a career out of it. (Companies pay $50k+ to fine-tune models on their data so they can get personalized AI models.)

Shoot your questions below. I'll be sharing in-depth raw findings about this topic in the coming days.

[Emmanuel Macron @EmmanuelMacron]

C’est la journée de l’Europe.

L’Europe est aujourd’hui une évidence qui pourtant n’allait pas de soi. Elle est un héritage arraché aux ruines, un trésor façonné par le courage de celles et ceux qui ont refusé que le nationalisme et la guerre soient notre destin.

Face aux crises, l’Europe n’a cessé de nous protéger et d’agir vite, fort et en solidarité quand l'Histoire frappe à notre porte. Dans la pandémie, dans les turbulences économiques, face à la menace russe et à la guerre en Ukraine sur le sol de notre Europe, nous résistons, toujours.

L’Europe est bien plus que les bénéfices de son grand marché unique : elle soutient notre agriculture, notre jeunesse et nos universités, notre recherche, nos territoires et nos emplois, notre diversité culturelle, nos exportations, nos frontières, notre sécurité et notre indépendance dans un monde de périls.

Bien sûr, l’Europe peut et doit encore s’améliorer. Il y a tant à faire encore.

Mais nous devons être fiers d’être Européens. Fiers de bâtir le continent le plus écologique, le plus exigeant sur le numérique, celui qui investit dans l’innovation et la technologie pour produire en Europe et sortir de nos dépendances stratégiques, celui qui défend partout les valeurs démocratiques et humanistes.

Depuis 2017, j’y consacre mon énergie, pour les Françaises et les Français, parce qu’une partie significative de notre avenir et de notre souveraineté se joue là : l’Europe respecte et renforce nos nations.

À chaque génération revient le devoir immense de faire vivre l’Europe, l’aimer, la transformer, pour qu’elle soit forte, puissante, indépendante, qu’elle nous serve tous et qu'elle protège ce que nous avons en partage : une certaine idée de l'Homme et une capacité à agir pour assurer nos choix libres et souverains.

C’est encore plus important dans un monde qui aujourd’hui vacille où notre trésor de paix, d’unité et de souveraineté européenne a une valeur inestimable.

En ce 9 mai, en Européen convaincu, déterminé et fier, je dis très simplement :

Vive notre Europe !

I completely agree with her assessment that “Claude has regressed to the point it cannot be trusted to perform complex engineering”.

There are two problems with building businesses on top of frontier models. The first is the cost and value capture. The frontier labs are aiming to capture the value that they create and become the new Google, Facebook where, in the past, you would raise venture money to scale your SaaS and you would spend marginally all of it on CPC ads for customers acquisition. Then all that value accrues to Google/Facebook stock. The goal with the frontier labs is capture all that value instead. There is no incentive to bring costs down or democratize access, that’s going to have to come from innovation outside those labs.

The second is the “they’re not going to let us have this” problem. (phrase coined by @androolloyd in our discussions/strategizing about this around the turn of the new year) Opus 4.5 was good enough that you could actually make serious progress with it.

Now that they’ve gotten everyone hooked on crack, they’ve diluted the package. It’s been brutal for over a month. The amount of money we’ve spent on the API for this degraded product makes me sick. They have completely nerfed it and there’s a good chance Mythos is just them re-releasing an unquantized version of the same/similar thing that we already had, just in a way that’s more economically sustainable for them. And which is rumoured to be gatekept by organization. If you’re operating in this field you have to take these dynamics into account and act accordingly.

@OSRDrivers Age of AI productivity. Still “90 days” for a reply.

[Adrian Salceanu @essenciary]

@koylanai yup, got the same yesterday. told it to undo the latest changes which broke features instead of fixing bugs, and it wiped all the uncommitted work. previously, undoing would make it walk back the changes in code.

Vaya puto escándalo.

@karpathy @karpathy I've been building something for a while now. For now it's just for personal use bu I would love you to try it if you want to take it for a spin.

[Enrico Letta @EnricoLetta]

Los 27 por fin d’acuerdo en dejar de ser 27 para convertirse en 1, integrando definitivamente un Mercado Único 🇪🇺 que sigue fragmentado; energía, télécom, mercados financieros, Régimen 28, Quinta Libertad. El plan “One Europe One Market” marca un paso decisivo. Ahora velocidad.

[European Commission @EU_Commission]

We are introducing EU Inc. To make building and growing a business across the EU faster, simpler, and smarter.

🔸 Start a company in less than 48 hours
🔸 No minimum capital requirement
🔸 Fully online and borderless

[Ursula von der Leyen @vonderleyen]

To help EU Inc. companies compete for the best people, employee stock options will be simpler to offer and easier to manage across borders.

We will also fully digitalise insolvency procedures and introduce a fast-track insolvency process for startups.

So that EU entrepreneurs can start again, more easily.

[Ursula von der Leyen @vonderleyen]

EU Inc. creates a single European company framework.

It is one simple set of rules that works across our entire Single Market of 450 million consumers.

Companies will be able to manage their documents and communicate with administrations fully digitally, in all 27 Member States.

@TimurNegru how much would it cost to renovate this?
