Sample efficiency defines the true trajectory of artificial intelligence
The data black hole at the center of AI
Understanding whether AI progress is driven by scaling or genuine algorithmic learning efficiency determines the ultimate limits of machine intelligence.
- 1Sample efficiency serves as a core metric for defining and measuring true algorithmic intelligence.
- 2Recent AI progress may rely more on scaling massive data and compute than genuine learning improvements.
- 3The reliance on massive data scaling raises critical questions about the future trajectory of AI development.
The brief
Recent breakthroughs in artificial intelligence have stunned the world, but they mask a fundamental question about how these systems actually learn. We must ask whether AI is truly getting smarter or just consuming massive amounts of data.
True intelligence can be defined by sample efficiency, which measures how effectively an algorithm learns from limited data. While humans can master concepts from a few examples, modern AI still requires vast oceans of information to achieve competency.
This raises a critical tension for the future of technology. If progress relies entirely on scaling up data and compute rather than improving algorithmic efficiency, we may soon hit a hard ceiling as high-quality training data runs out.

AI progress is primarily driven by better data and greater data-generation compute.
“The main way that AIs have been getting better is from adding more and better data and scaling the compute required to develop that data in the first place.”

Reinforcement learning requires models to have prior probability for correct solutions.
“For this process to work, the model must have at least some prior probability to anticipate the correct solution in the first place.”

AI competence across fields requires vast human-expert trajectories for each skill.
“Which is why you need mind stretching amounts of human expert trajectories in every single field and skill that you want the model to eventually be competent in.”

Each AI skill requires at least hundreds of human experts producing examples, rubrics, and reasoning.
“Each skill corresponds to at least hundreds of human experts who are generating example completions, writing rubrics and explaining their chain of thought.”

The AI data and reinforcement-learning-environment industry earns billions annually and may soon reach tens of billions.
“There's a reason that the data industry that is producing these expert labels and the RL environments in which these meticulously cataloged skills can congeal, is earning billions a year in revenue, soon to be deca. Billions.”

Data-driven progress makes it relatively easy for open models and laggards to approach frontier systems.
“I think the reason it is relatively easy for open source and previous laggards to catch up to within months of the frontier is that data is the real driver of progress.”
Listen at 2:29
Public APIs make AI training data easier to distill than technical optimization methods.
“And data can be easily distilled from public APIs, whereas hyperparameters and training tricks and architectural optimizations cannot.”
Listen at 2:39
Frontier AI models train on tens to hundreds of trillions of tokens.
“These frontier models are trained on somewhere between tens to hundreds of trillions of tokens.”
Listen at 3:27
Current AI systems learn substantially less efficiently than humans.
“But the reason we can't do this is that our AIs learn much less efficiently than we do.”
Listen at 3:51
Millions of demonstration hours do not enable AI to perform complex open-ended tasks.
“And even with the millions of hours of demonstrations that we've collected, this is not enough to to allow them to perform complex open ended tasks.”
Listen at 3:56
Human driving practice uses far less training data than Waymo and Tesla’s models.
“that is still three to four orders of magnitude less data than Waymo and Tesla are using to train their self driving car models.”
Listen at 4:13
The human genome is approximately three gigabytes, with one to two percent protein-coding.
“Our genome is only 3 gigabytes big and only 1 to 2% of it is protein coding.”
Listen at 4:46
Evolution supplied learning hyperparameters and loss functions, while individuals build their brain connectomes.
“I think the closer analogy is more that evolution found the right hyperparameters and the right loss functions and that within our lifetime we are still from scratch building up the connectome in our brain”
Listen at 4:59
Pretrained AI still requires enormous data for each additional skill.
“But these AIs, even once they're pre trained, still require enormous amounts of data to learn the next marginal skill and the next marginal skill after that.”
Listen at 5:39
Blind and deaf people can retain general intelligence without ordinary sensory information.
“blind and deaf people who have been cut off from all the sensory information still have general intelligence.”

Under Chinchilla scaling, unlimited parameters reduce required data by only roughly tenfold at fixed loss.
“Even if you increase the number of parameters by infinity, that would only decrease by a factor of 10 the amount of data that you need in order to keep the same loss.”
Listen at 7:14
Humans are thousands to millions of times more sample-efficient than current AI models.
“Humans are somewhere between thousands to millions of times more sample efficient than these models.”
Listen at 7:23
Scaling current model size alone cannot close the human-AI sample-efficiency gap.
“So scaling the size of current models simply can't make up for that discrepancy.”
Listen at 7:28
AI will increase overall demand for human software engineers by 2027.
“I would be willing to bet that there's overall more demand for human software engineers in 2027 than there is right now, largely due to the complementary input of AI.”
Listen at 10:44
AI labs plan to automate AI research and use automated researchers to solve sample efficiency.
“The labs plans for this latter category of jobs is first to automate AI research and then have the automated AI researchers solve the sample efficiency problem.”
