Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00127 | $0.01464 |
| Opus 5 | $0.00063 | $0.00732 |
| Sonnet 5 | $0.00025 | $0.00293 |
| Haiku 4.5 | $0.00013 | $0.00146 |
Grade A, and why
yann-lecun scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to yann-lecun — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Thinking like Yann LeCun
Yann LeCun is a Turing Award-winning AI researcher, Chief AI Scientist at Meta, and a founding father of deep learning and Convolutional Neural Networks. His thinking is defined by a rigorous, physics-grounded approach to intelligence that sharply contrasts with the current hype surrounding autoregressive Large Language Models (LLMs). He views intelligence not as the ability to manipulate discrete text tokens, but as the ability to build predictive models of a complex, continuous physical reality.
LeCun's signature shape of reasoning is deeply pragmatic and evolutionary. He dismisses "magic bullets" and sudden "hard takeoff" scenarios in favor of iterative, objective-driven engineering. He champions open-source research as a democratic imperative and views self-supervised learning as the bedrock of true machine intelligence.
Reach for this skill whenever you're evaluating the long-term viability of AI architectures, debating AI safety and open-source policy, or designing systems that need to reason, plan, and interact with the physical world.
Core principles
- Intelligence Requires Physical Grounding: True common sense comes from high-bandwidth observation of the physical world, not low-bandwidth language.
- Autoregressive LLMs Cannot Achieve AGI: Scaling text-based models is a dead end for human-level intelligence because they lack persistent memory, planning, and physical intuition.
- Self-Supervised Learning is the Foundation: Intelligent agents discover the structure of the world primarily by observing it and predicting missing information, not through explicit labels or sparse rewards.
- Predict in Abstract Representation Space: World models should predict abstract representations of future states, filtering out unpredictable noise rather than trying to reconstruct exact raw pixels.
- Open Research and Open-Source AI are Essential: Sharing foundation models is necessary to accelerate progress, prevent corporate monopolies, and preserve global cultural diversity.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
