En esta prueba he querido poner Claude al límite con Houdini (modelo Opus 5.5). He montado toda la escena hablándole al iPhone para ver dónde está el límite, y mi conclusión es que no hay límite. Esto que veis es donde he puesto el freno, hay cosas que corregir aún pero quiero seguir experimentando con otros proyectos.
El render ha tardado 50 horas en mi 5090 dado lo compleja que es la escena, volumétricas etc.
El color grading lo he hecho en Davinci trabajando en Aces y también lo hice hablándole al teléfono con el MCP de Davinci.
Me cuesta imaginar un futuro donde no vayamos a trabajar con esto de forma masiva.

YOLO finds people, a local 27B vision-language model (Jev, MLX 4-bit) decides on each crop: helmet? vest? risk 0-5?
Zero-shot, no training, on a MacBook M5 24 GB.
Helmet violations, given the person boxes: 99.5% accuracy vs 96.6% for a fine-tuned YOLO

Why locate objects one token at a time? This 4B diffusion model generates grounding predictions in parallel, delivering a 4.51× speedup while setting a new SOTA across 30 benchmarks.

Claude writes about 90% of Claude Code's code.
From June to September, merged PRs more than doubled while the share reverted fell by more than 40%.
We wrote about how we changed code review to get there, and how to adopt it:

Code Review is now generally available for Claude Team and Enterprise plans.
Reviews are now faster, catch more of the bugs that matter, and admins can pick from Quick, Standard, or Deep review levels for each repo.

Hi, I'm Felix. I'm an eng lead working on Claude. I love watching people take flight and do things they never thought possible.
We often describe that as "being more ambitious" when using AI, which is tricky advice to follow. I wrote a tutorial:

Introducing Indra, a 1M parameter OCR model:
- 49 pages/s on CPU, 11x faster than PaddleOCR and 17x Tesseract
- Beats them on OmniParseBench text (41.3 vs 35.8 and 19.3)
- Full layout and line bounding boxes
Really accurate take
I think one thing that's a bit dishonest that I saw a lot yesterday about the "software is dead" post and I don't blame them is people at all the AI companies kinda replying "omg yes it's the best time to build a startup ever"
I mean yes, but you have to translate it to "omg best time to pay my company money for tokens to build your startup ever"
And you have a lot of people who are already rich (post-money) who say similar, because they don't need to pay their bills with their salary anymore
I'm also incentivized to say all this, half of my net worth is in AI stock (Google, SpaceX, Nvidia, and tech ETFs), I love to see their stock go up, but I care mostly about being real and no personally I don't think it's the best time to be in software ever, even if it's very unpopular to say this
I think it's definitely the best time ever for creativity, you can make things now you couldn't even imagine being possible to make just a few years ago, that doesn't necessarily translate to money though
There's ~40 million software developers in the world
There's 2 billion people regularly using AI tools now
So that's 50x, it'll grow to the same number as internet access, that's 6 billion people, so 200x more AI users than devs
Once AI agents can do the dev work (they already can), that means something for software, even if it's not right now, but it'll mean something in a few years
Many people predict this will cause the cost of everything to go down, and life will get cheaper, which is a good thing
It just doesn't mean as a software developer or entrepreneur you'll be paid for the same thing in the future you're paid for right now (maybe other moats, maybe UBI, etc)

Introducing Muse Wonder, our new family of frontier models with state of the art performance for personal and professional agentic work.
Santiago retweeted
We were able to fine tune an open weight model (Qwen3.5-9B) on proprietary internal data at @coinbase, and it out performed frontier models, at much lower cost and speed, for a specialized task (fraud prevention in this case).
I think we'll see more of this pattern inside companies. The frontier models are amazing generalists. But increasingly you'll see specialist models out perform on more narrow tasks, either working on teams, or by themselves.
We're making it easy to fine tune models internally for our employees. We even have a skill for it in our internal harness that makes it easy to spin these up and start training them:
"/fine-tune-and-serve-llm I want to fine-tune Qwen for payments risk review. help me get started"
I imagine we'll have some backend services that could be replaced entirely by this new architecture.

Ben Affleck (Hollywood star & Artists Equity CEO) talks about how he fine-tunes open video models by unfreezing weights and trained only the last cinematic layer so a film crew can hit real production standards.
for context, Ben Affleck founded InterPositive in 2022, a 16-person AI shop for film post and Netflix bought it in March 2026 for $587 mn in cash.
He needed that model because public video models were trained on his peers' films, and he did not think that was a real business. So InterPositive raised money, shot its own dataset for 8 months on a controlled stage, and used it only as late-stage training.
Each new film then trains a private model on its own dailies, so the production keeps the footage and the learning. That is the product Netflix paid $587 million for.

We'll be spending a lot more time trying to understand the outputs of language models. A few thoughts, tips & tricks:
Writing. Something I've had success with: Ask your LLM to explain something in ASD-STE100, it's a controlled language specification originally developed for aerospace maintenance documentation. LLMs well-versed in this language and it comes with heavy constraints on clean writing style that I often find a lot more readable. Sometimes I've tried to soften it a bit e.g. ask for "80% of the way to ASD-STE100" because the spec is quite stringent. But even better:
Diagrams / images. Instead of writing, ask your LLM to create a diagram. These can be a lot easier to process, parse, and understand. But even better:
Web pages. Ask for output "in HTML" to get a beautiful, interactive webpage. LLMs are getting really good at frontend and can create beautiful experiences, animations, etc. But even better:
Explainer videos. The output format I am most bullish on is fully custom / bespoke explainer videos generated on any arbitrary topic. Experiment with things like "Create a 3b1b style video explainer on X. Use my ElevenLabs API key for audio narration". (you'd need an API key for the latter or you can ask your LLM to find you decent free alternatives that use your local compute). This is actually starting to work!
In summary:
- As LLMs get better, they will do more and more of the legwork autonomously, and a lot more of our work will rise up the abstractions into oversight and understanding.
- Luckily, LLMs can help here too because as intelligence and code are increasingly abundant, you can ask for large, custom, discardable software artifacts (e.g. web apps, video explainers) that would have never made sense to create before. Push the boundaries here and you'll be surprised.
