THOUGHTS ON THE JOB MARKET IN THE AGE OF LLMS

AI makes senior workers more covetable because they have more context on how to work in and steer complex systems over time. Junior workers have to show a desire to make progress, as with enough motivation, they can scale to impact quickly. The AI job market is brutal for junior workers and comes with a ton of opportunity costs. Making open source contributions is an established way to develop a career in AI. This is a bit easier in the age of AI, but standing out amid the sea of slop will be hard.

SYNTHETIC PRETRAINING

Synthetic pretraining is the large-scale use of synthetic data sources throughout training. It is a practical response to the fact that it is difficult to collect data that reliably produces the capabilities we want. Synthetic pretraining seems to open up a new simultaneous space of data and model innovation. This post looks at what synthetic pretraining is, how it works in practice, and the stages of synthesis.

🎙️INSIDE A CHINESE AI LAB: HOW MINIMAX BUILDS OPEN MODELS

Chinese labs move fast through first-principles thinking, engineering discipline, and willingness to work whenever the model in experimentation requires them to. This post features an interview with MiniMax's senior researcher, Olive Song, that looks at how cutting-edge AI research is actually done inside a Chinese lab. It covers topics like alignment, things that can derail training, agentic RL, coding and general intelligence, and more. The interview is also available in video.

IF THE SUPERINTELLIGENCE WERE NEAR FALLACY

People think that superintelligence is a lie that tech bros are selling because they are just trying to raise money. People just need to look at benchmarks and use AI to see for themselves where the technology is headed. Most people don't understand AI safety. The discourse will improve once they see that superintelligence is really not that far away.

QUANTIZATION-AWARE DISTILLATION FOR LLMS AND VLMS

NVIDIA's QAD is a method that uses KL divergence loss to distill full-precision models into quantized students. It enables stable and accurate quantization for complex LLM pipelines without full retraining, recovering near-BF16 accuracy across several Nemotron variants.

INTRODUCING NVIDIA COSMOS POLICY FOR ADVANCED ROBOT CONTROL

Cosmos Policy is a robot control and planning policy that post-trains the Cosmos Predict-2 world foundation model for manipulation tasks. It adapts the pretrained model directly through a single stage of post-training on robot demonstration data. Cosmos Policy treats robot actions, physical states, and success scores just like frames in a video. As a result, a single model can predict action chunks to guide robot movement using hand-eye coordination, predict future robot observations for world modeling, and predict expected returns for planning.

SHAPING CAPABILITIES WITH TOKEN-LEVEL DATA FILTERING

Filtering pretraining data is a highly effective, robust, and inexpensive-at-scale way to reduce undesired capabilities in language models. Filtering tokens is more effective than filtering documents. Filtering gets more effective with scale. It is robust to noisy labels with sufficient pretraining compute.

APPLE LOSES MORE AI RESEARCHERS AND A SIRI EXECUTIVE IN LATEST DEPARTURES

Apple has lost at least four AI researchers in recent weeks and a top Siri executive. Haoxuan You and Bailin Wang left to work at Meta, while Yinfei Yang left to start a new company. Zirui Wang and Stuart Bowers are joining Google DeepMind. Apple has struggled to keep up with its peers in the AI race. Its decision to outsource some technology to Google has rankled staff, and the company has seen an exodus of talent in recent months.

CHAT IS GOING TO EAT THE WORLD

Humans prefer to do things through conversation. Traditional user interfaces are bad at this because they force people to already know what they're looking for. Chat allows people to discover what they want. Chat can now complete the transaction, not merely recommend options, signaling the start of a paradigm shift comparable to the transitions from desktop to web or from web to mobile.
