does Jev understand colour?
incredible model, very cheap and fast. definitely feels like a leap forward for creating new UX/UI paradigms on top of modern language models.

We finished the Training Agents series. Six live sessions over six months, from evaluating agents to training them inside real environments. All of it is on the Hugging Face YouTube channel and all of the code is open.
Here's what we did and who made it happen:
1. Agentic Evaluations WorkshopWhere agent evals actually stand, and why benchmark scores don't match what people see in use. With Avijit Ghosh and Nathan Habib (Hugging Face), Arvind Narayanan (Princeton), Pierre Andrews (Meta), J.J. Allaire (UK AI Security Institute) and Mahesh Sathiamoorthy (Bespoke Labs).
2. RL for Agents Workshop Environments, rollouts, reward design and the inference bottlenecks that appear when you move from RL for LLMs to RL for agents. With Lewis Tunstall (Hugging Face), Will Brown (Prime Intellect), Ofir Press (Princeton) and Alex Zhang (MIT CSAIL).
3. Training Agents 1: SFT on agent traces Public coding-agent traces turned into prompt/completion data, a TRL + LoRA fine-tune on Hugging Face Jobs, metrics in Trackio, and an honest look at what the first eval numbers can and cannot tell you. Joined by Sergio Paniego and Quentin Gallouédec.
4. Training Agents 2: Distillation Off-policy, on-policy and self-distillation for moving capability from a teacher into a smaller coding agent.
5. Training Agents 3: Reinforcement learning GRPO after SFT: group sampling, verifiable reward functions, reading the reward/KL/length curves, and three experiments, one of them with a deliberately gameable reward so we could watch the hacking happen.
6. Training Agents 4: From reward functions to environments The reward stops being a function and becomes a place the agent acts in. We walked the reset()/step() contract from Gym to LLM agents, built an OpenEnv environment and pushed it to the Hub, plugged it into TRL's GRPOTrainer, then trained a real coding agent (OpenCode) through Harbor with AsyncGRPOTrainer on Hugging Face sandboxes.
The series has passed 300k views. Thank you to every speaker, to the TRL team, and to everyone who showed up live with questions.

Spent 3 weeks building a texting app slower than email. Messages fly at pigeon speed — LA to NYC takes 22 hrs. Sometimes the bird dies & the message isn’t delivered.

I'm available for new projects starting mid-July.
As a Fractional Design Lead and Independent Design Contractor, I embed with teams to set direction, raise the design bar, and still care about the details. Brand, product, design systems, design engineering with AI. From early positioning to shipped interfaces. I also consult teams at the intersection of design and tech.
A short note on smalltribe: after a few years as a two-person studio, I've changed the setup. I'm running the practice solo now, with a network of senior freelancers I trust and bring in per project. Smaller core, more flexibility, same standards. Honestly, it feels right.
Best fit: early-stage to growth-stage companies who treat design as a strategic lever. 18+ years of experience, with companies like Spreadshirt, acto, Kontist and Staffbase.
If you're looking or know someone who is, reach out or share this post. Thanks!

I can’t wait for the open source ecosystem to catch up on frontier models and local AI becoming the norm.
Fable 5 is (was) a great model. RIP.
The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.
The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.
Access to all other Claude models is not affected.
We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

How do you know your agent is still running after you close the lid?
I became a bit obsessed with putting some RGB LEDs for a status indicator into the SD Card slot on my MacBook Pro.
I never use that slot, so it's a perfect place.

Introducing Roughdraft!
A new open source project designed to make collaboration with agents better.
The idea is to bring commenting and suggested changes to markdown (e.g. plan docs) in a nice interface.
Free, local, etc.

Meet Stable Audio 3.0, the open-weight model family built for artistic experimentation.
This is our open invitation to experiment with generative audio. We believe the best innovations are still waiting to be built.
The 4-1-1 on 3.0:
📣 You own your outputs, and can distribute and commercialize them under the Stability AI Community License (up to $1 million in revenue).
🎵 New and improved capabilities include variable-length generation up to six minutes, and full song composition on portable devices, no GPU required.
✅ Trained on a fully licensed dataset.
🎨 You can customize the models on your own library with support for LoRa training, which we’ve documented for the first time.
More on the models 👇

Great new library by @raphaelsalaja, uses Web Audio synthesis for UI sounds
the web has been quiet for a while.
for the past few months i've been building something to fix that. declarative audio for the web. describe a sound as plain data, play it with one call.

Vue + Lynx 💚
🤯 @Vuejs -> @Lynxjs_org -> the Web
Mind-blowing how all these demos just work.
The loop is closed.

We made a tool that lets you absorb the vibe of anything you point it at and apply it to your designs
It's absurd and it just works
