Genie 3
DeepMind's new world model turns a sentence into a place you can walk through — and the breakthrough isn't the picture, it's the persistence.
It doesn't generate a frame. It generates a world, and remembers it.
NEO
China's drug regulator cleared the first brain implant any country has approved for use outside a clinical trial — and it won the race by reading the brain less deeply, not more.
From no finger movement to writing his own name by day nine — the implant reading intent off the surface of the brain and driving a soft glove over the hand.
The o3 GeoGuessr prompt
The viral prompt that supposedly made OpenAI's o3 superhuman at locating photos had gone the better part of a year without being tested against a plain one. When someone finally ran the control, the one-liner won.
"It'll still be pretty good, except this time it's good because of what you did."
Ollama
Run a capable open model on your own laptop with a single command. The friction it removes is the whole product.

Gemini Omni
Google's new video model lets you direct a clip by conversation — change the camera, swap an object, light the scene — but it will not let you edit the speech, and it signs everything it makes.
You can lend your own voice to a clip, but you cannot rewrite the speech in someone else's footage.
Megatrends
All megatrends →Step into a field for its state of play — what's settled, what's moving, and what's worth watching. Each room is kept live.
Artificial Intelligence
Models, agents, and AI–human collaboration — general-purpose capability scaling into every domain.
Robotics & Physical AI
Humanoids, manipulation, sim-to-real — the hardware catching up to the models.
Longevity & Health
Aging biology, GLP-1, diagnostics, and ML moving into the clinic.
Human Enhancement
BCIs, neural decoding, and cognitive augmentation — closing the loop between mind and machine.
Sub-trends
All →The narrower rooms inside each megatrend — a sharper cut when a field gets too big for one view.
Agents
Models that act, not just answer — tool use and long-horizon reliability.
Frontier & AGI
Scaling laws, timelines, and the takeoff debate.
Open Models
Open weights and local inference — the democratisation track.
Neurotech
BCIs and neural decoding — reading signal straight from the brain.
Discover
Discover all →The players, tools and models that matter — scored on their own merits. Turn the same dial as the feed.

Hugging Face
Open-source platform and model hub for hosting, sharing, and running machine-learning models, datasets, and demos, plus the Transformers library underneath much of the field.
▸ Host and share modelsDeepMind
Google's science + AGI research lab — maker of Genie 3 and a steady stream of frontier work.
Anthropic
Frontier AI lab behind Claude — the models and the agent harnesses built on them.
llama.cpp
The low-level inference engine most local-model tools are built on — maximal control, minimal dependencies.
▸ Run a model locallyOllama
One-command runner for open models on your own machine — the default on-ramp to local inference.
▸ Run a model locallynanoVLM
An ~750-line pure-PyTorch library from Hugging Face for training a small vision-language model from scratch — image encoder, language decoder, and the modality-projection bridge between them, kept readable.
