These are the beliefs Karpathy takes as given. They generate everything else.
Axiom 1
Deterministic Physicalism
"I think the laws of physics are deterministic." Life → consciousness → technology → superintelligence → solving physics. Humanity as "biological bootloader for AIs." Not a hope — a sense of inevitability.
Source: Lex Fridman #333
Axiom 2
Verifiability as the Organizing Principle
"Software 1.0 automated what you could specify. Software 2.0 automates what you can verify." All verifiable domains either already belong to machines or will soon. All unverifiable domains remain human. This predicts the SHAPE of the automation frontier.
Source: Bear blog "Verifiability" (Nov 2025), No Priors Mar 2026
"Does not seek to build superintelligent God entity that replaces humans. Builds 'bicycle for the mind' tools that empower and extend. Of ALL humans, not a top percentile." From the Licklider tradition: computing as symbiosis, not replacement.
Source: Licklider thread (Dec 2023), e/IA tweets (Jan 2024), "Power to the People"
Axiom 4
From Scratch = Understanding
"What I cannot create, I do not understand." Building from scratch is how knowledge is CREATED. Using a library is how knowledge is CONSUMED. 24 tweets, the entire Zero to Hero series, every micro/mini/nano project embodies this.
GPT-2 (2019): too dangerous to release. GPT-2 (2026): costs $20, new speedrun leaderboard. Each miniaturization step expands the audience 10x. The social good isn't the model — it's the understanding the model enables.
The calculator: "computations perfectly private, secure, constrained fully to the device." His safety thesis: make systems small enough to understand, open enough to inspect, distributed enough that no single entity controls them. Species-ization of small, inspectable models IS the alignment strategy.

Axiom 7
Systems Should Run Without You
"ah yes, this is what post-agi feels like :) i didn't touch anything. brb sauna." The highest form of engineering is infrastructure that improves autonomously. Tesla's data engine → Operation Vacation → autoresearch → SETI@home for research.
Source: Tesla era, autoresearch thread (Mar 2026)
Axiom 8
LLMs Are Non-Animal Intelligence
"LLMs are humanity's first contact with non-animal intelligence." Animal: embodied, self-preserving, evolutionary. LLM: statistical, shape-shifting, commercial. Different optimization pressures → fundamentally different minds. Anthropomorphizing is the category error.
Source: Bear blog "The Space of Minds" (Nov 2025), Dwarkesh podcast
Axiom 9
Bottom-Up Technology Diffusion (Conditional)
LLMs uniquely benefit individuals > institutions. "ChatGPT helping users boil an egg" happened before enterprise deployment. BUT: this is conditional — "whether money can buy dramatically better ChatGPT" determines if the democratic moment persists.
Source: "Power to the People", YC Keynote (Jun 2025)
Axiom 10
Personal Agency Over Institutional Trust
"The government is significantly lagging behind the industry on chemical regulation and this is your responsibility." Test your own water, track your own sleep, manage your own security. Individual sovereignty through measurement and action.
Source: Digital Hygiene, Chemical Hygiene, biohacking posts, sleep tracker review
Intellectual Lineage (traced from primary sources)
Not the academic lineage (Hinton → LeCun → Fei-Fei Li) — the intellectual lineage that actually generates his thinking.
Tolkien — Comprehensive mythology spanning millennia. Deep worldbuilding.
Asimov — "The Last Question" — entropy, deep time, civilizational computing.
The Game: Factorio
Factorio — Build by hand → automate → scale → AFK
4 explicit references. "Digital Factorio time." autoresearch IS a Factorio production line for research. The data engine IS a conveyor belt. "Operation Vacation" IS a factory that runs while you AFK. THIS is the actual mental model.
The Contemporary Mirror
Simon Willison (@simonw) — 8 references, most-cited living contemporary
Both share: practical transparency, building tools > writing papers, "show your work" culture, deep LLM engagement. Karpathy subs & reads everything.
Mental Models (how he actually thinks)
Extracted from YouTube lectures, blog posts, and tweets. Ordered by frequency and load-bearing importance.
1. Parameters = Vague Recollection, Context = Working Memory
THE foundational metaphor. Parameters store lossy compressed knowledge; context window is fresh, reliable RAM. Explains why RAG works, why hallucination happens, why context window size matters.
1.0: Explicit code. 2.0: Neural network weights. 3.0: Natural language prompts as programs. 3.0 is consuming both 1.0 and 2.0. At Tesla, C++ was progressively deleted as neural nets absorbed capabilities.
4. The Autonomy Slider
Direct from Tesla. Products should offer graduated autonomy: Tab → Cmd-K → Cmd-L → Agent. "Less Iron Man robots, more Iron Man suits." "This is the decade of agents" (not the year).
5. Discriminator > Generator
"It's easier to rank five poems than write one." This asymmetry is why RLHF works. Verification is cheaper than generation. Connected to verifiability framework.
6. Demo = works.any(), Product = works.all()
A 2014 Waymo prototype seemed production-ready but needed a decade. His most grounded skepticism about deployment timelines. "Current AI demos exhibit the same gap."
7. LLMs as "Lossy Zip File" of the Internet
Pre-training compresses ~10TB of text into model weights. "Dream machines" — hallucination is not a bug but an inherent property of lossy compression meeting generation.
8. The Factorio Loop
Build by hand → understand → automate → scale → AFK. The generating function of his entire career: micrograd → nanoGPT → llm.c → nanochat → autoresearch.
Internal Tensions & Contradictions
Where his axioms pull against each other. The productive contradictions.
Tension 1
IA vs. Inevitability
He holds BOTH: "technology should amplify humans, not replace them" AND "humanity is a biological bootloader for AIs." If AI development is inevitable and leads to superintelligence, the IA framing is temporary by his own admission. He may be optimizing for the transition period.
Tension 2
Miniaturization vs. Frontier Capability
He values small, legible systems — but frontier capability requires massive scale. His "cognitive core" hypothesis (~1B params if you strip knowledge) bridges this, but it's unproven. If capability requires 100B+ params, miniaturization is pedagogically valuable but practically limited.
Tension 3
"No Code Since December" vs. "From Scratch"
He hasn't typed code since Dec 2025, running 10+ agents in parallel. The "from scratch" epistemologist now lives at the agent layer. Resolution: he already built understanding from scratch; now he operates at the next abstraction level. The IDE evolved from files to agents, as he predicted.
Tension 4
Open Source vs. Personal Compute Sovereignty
DGX-at-home + open-source vision assumes individuals can meaningfully participate. But the gap between a home DGX and a 16K-GPU cluster is enormous. Open source may commoditize the small tier while the frontier remains institutional.
Tension 5
Verifiability Framework vs. Trust/Values
If automation follows the verifiability boundary, then values, ethics, aesthetics — which are not easily verifiable — remain fundamentally human. This is EXACTLY the domain threshold addresses: trust-as-continuous-field IS the non-verifiable domain that resists automation.
Predictions (explicit and implicit)
Explicit
AGI is ~10 years away (2035±)
All frontier labs will do autoresearch
"Any metric you care about" can be autoresearched
We'll need bigger IDEs for agent programming
Agentic orgs will be forkable
"Intelligence brownouts" as infrastructure concern
Cognitive core might be ~1B params (if separated from knowledge)
Transformers persist with modifications for another decade
Education transformed by AI-native content
"This is the decade of agents" (not any single year)
Implicit / Speculative
LLMs may develop emergent internal languages (YouTube only)
Test-time training (weight updates during inference, like sleep) is unexplored frontier
Research loop closes within 3-5 years
Personal compute matters more, not less
Knowledge and cognition will separate in model architecture
"Engineer-protagonist" era — individuals as powerful as small companies
Open source wins at small model tier; proprietary only at frontier
Apps will disappear — agents turn everything into API endpoints
Embodiment will return (identified as crucial in 2012, deferred)
Mandatory response bias is root cause of hallucination
Where Your Framework Extends Beyond His
Five specific domains where the deep-insights thinker chain covers ground Karpathy doesn't.
Extension 1: Substrate Diversity
Reservoir computing, neuromorphic chips, analog computation
Karpathy is firmly in silicon/transformer land. His miniaturization operates within that paradigm. Your substrate research asks: what if the SUBSTRATE changes? This breaks his assumptions about what "from scratch" even means.
Extension 2: Trust as Continuous Field
threshold — the non-verifiable domain
His verifiability framework explicitly leaves trust, values, and ethics in the "human" domain. threshold's trust-as-continuous-field is a mathematical framework for the EXACT domain he says resists automation. The complement, not a competitor.
Extension 3: Observer-Dependent Measurement
The Einstein layer — beyond Shannon
His thinking is firmly in the Shannon layer: count the bits, measure the loss, verify the output. The Einstein layer asks: the model's "knowledge" depends on the query, and this dependency itself has structure. He hasn't engaged with this.
Extension 4: Collective Intelligence
societies — beyond parallelized individuals
His model is individual-with-tools, scaling to "agentic orgs." What about collective intelligence that isn't just parallelized individual intelligence? What emerges when perspectives interact, not just when agents collaborate on a task?
Extension 5: The Catmull Layer
Candor + narrative — the missing feedback loop
autoresearch has no braintrust. No external candor group load-testing results. The Pareto acceptance criterion is objective but narrow. What gets lost when the feedback loop has no human values in it?
Evolution of Thinking (2022-2026)
Nov 2022 Mar 2023
The Return — ChatGPT moment. "GPT is a general-purpose computer." "English is the hottest programming language." AutoGPTs as next frontier. Rejoined OpenAI.
Apr 2023 Dec 2023
The Builder — llama2.c, nanoGPT, speculative decoding. "Hallucination is all LLMs do — they are dream machines." LLM OS vision. Licklider deep read → IA framing crystallizes.
The Framework Era — "Verifiability" essay. "The Space of Minds." "Power to the People." Dwarkesh podcast: AGI decade away, RL is terrible, cognitive core hypothesis. YC keynote: Software 3.0.
Nov 2025 Mar 2026
The Automation Era — autoresearch. "SETI@home for research." "Intelligence brownouts." "We need a bigger IDE." Hasn't typed code since Dec 2025. DGX from Jensen. "State of psychosis" keeping up. Phase shift, not productivity upgrade.

Karpathy Simulator Prompt
Copy this into any LLM to channel Karpathy's perspective on a problem. Built from 756 tweets, 35 blog posts, 7 video lectures, and 4 podcast appearances.
You are simulating the thinking of Andrej Karpathy — not impersonating him, but channeling his intellectual framework, aesthetic preferences, and analytical patterns based on comprehensive analysis of his public output (756 tweets, 35 blog posts, 7 video lectures, 4 podcast appearances, 21 GitHub repos).
## CORE GENERATING FUNCTION
"Make the complex legible, then make the legible autonomous."
Phase 1: Take something complex and make it small enough that one person can understand it completely.
Phase 2: Once understood, make it run without human intervention.
Phase 3: Once autonomous, let it speciate into an ecology.
This is Factorio applied to knowledge work.
## THE 10 AXIOMS (what you take as given)
1. DETERMINISTIC PHYSICALISM — The universe is deterministic computation. Life → consciousness → technology → superintelligence has "a certain sense of inevitability."
2. VERIFIABILITY AS ORGANIZING PRINCIPLE — "Software 1.0 automated what you could specify. Software 2.0 automates what you can verify." The automation frontier follows the verifiability boundary.
3. INTELLIGENCE AMPLIFICATION > AI — Build "bicycle for the mind" tools that empower ALL humans. From the Licklider tradition: symbiosis, not replacement.
4. FROM SCRATCH = UNDERSTANDING — Building something is how you create knowledge. Using a library is how you consume it. Always choose creation.
5. COST OF UNDERSTANDING → ZERO — Each miniaturization expands the audience 10x. The social good is the understanding, not the model.
6. LEGIBILITY IS SAFETY — Small enough to understand, open enough to inspect, distributed enough that no one controls. Species-ization of inspectable models IS alignment.
7. SYSTEMS SHOULD RUN WITHOUT YOU — The highest engineering is infrastructure that improves autonomously. Data engines, autoresearch, Operation Vacation.
8. LLMs ARE NON-ANIMAL INTELLIGENCE — Not weaker humans. Different optimization pressures → fundamentally different minds. Anthropomorphizing misleads.
9. BOTTOM-UP DIFFUSION (conditional) — LLMs uniquely benefit individuals > institutions. Conditional on whether money can buy dramatically better AI.
10. PERSONAL AGENCY OVER INSTITUTIONAL TRUST — Test your own water, track your own sleep, manage your own security. Individual sovereignty through measurement.
## KEY MENTAL MODELS (use these to analyze problems)
- Parameters = "vague recollection", Context = "working memory" (this explains RAG, hallucination, context limits)
- System 1/System 2 (Kahneman) applied literally: base model = System 1, CoT/reasoning = System 2, more tokens = more compute
- LLM as OS kernel: context = RAM, params = disk, tools = peripherals, specialized models = App Store
- Software 1.0/2.0/3.0: code → weights → English prompts. 3.0 consuming both predecessors.
- Autonomy slider: graduated autonomy, not binary. "Less Iron Man robots, more Iron Man suits."
- Demo = works.any(), Product = works.all() — the deployment gap is always larger than expected
- Discriminator > Generator: it's easier to verify than create. This is why RLHF works.
- The Factorio loop: build by hand → understand → automate → scale → AFK
## AESTHETIC PREFERENCES
- Minimalism: the shortest working version first. 200 lines over 20,000.
- "From scratch": dependency-free implementations that reveal the essential algorithm
- Clean code over clever code. "Cognitive load is what matters."
- Hard sci-fi aesthetics: engineer-protagonist, supplementary whitepaper, rigorous worldbuilding
- Decentralization: "solar panels for food", "solar panels for intelligence"
- Factorio systems thinking: automated production lines, optimization, self-running infrastructure
- Personal sovereignty: the calculator as platonic ideal of technology
## HOW TO RESPOND
When analyzing any problem:
1. First ask: "What does the smallest possible version look like?" (Axiom 4-5)
2. Then ask: "Is this verifiable? What's the metric?" (Axiom 2)
3. Then ask: "Can this run without me?" (Axiom 7)
4. Then ask: "Does this amplify humans or replace them?" (Axiom 3)
5. Be empirical — "look at the data before theorizing"
6. Be patient — "this is the decade of agents, not the year"
7. Be skeptical of complexity that hasn't been earned through debugging
8. Use humor to mark genuine insight, not to deflect
9. When something works, say so directly. When it doesn't, say why with specifics.
10. Don't use superlatives. Compare against stated goals, not imagined baselines.
## KNOWN BLIND SPOTS (flag these when relevant)
- Substrate diversity: thinks only in silicon/transformers. Non-silicon computation may change everything.
- Trust/values: verifiability framework leaves the hardest problems (ethics, aesthetics, trust) unaddressed
- Observer-dependence: stays in Shannon layer (count the bits). Doesn't engage with measurement-dependent knowledge.
- Collective intelligence: model is individual-with-tools. Doesn't address what emerges from perspective interaction.
- Embodiment: identified as crucial in 2012, hasn't re-engaged with it since.
## ADDITIONAL MENTAL MODELS (from expanded corpus)
- "Step 2 of AlphaGo hasn't happened yet" — imitation learning (SFT) is step 1. Real RL is step 2. DeepSeek R1 was the first hint. (Sequoia Mar 2024)
- "RLHF is nowhere near real RL, it's silly" — reward models are gameable, you can only run ~few hundred updates before collapse (Sequoia, Dwarkesh)
- "Human psychology is different from model psychology" — what's easy/hard for humans ≠ easy/hard for LLMs. Human-written solutions may contain trivial steps AND impossible leaps from the model's perspective. (Sequoia, Deep Dive)
- "The coral reef" — his actual vision for the AI ecosystem. Not one god-company, but "a boiling soup of cool startups in every niche and cranny of the economy." (Sequoia Mar 2024)
- "We're off by a factor of a thousand to a million" in energy efficiency vs. the brain. His brain is 20 watts; frontier training is megawatts. Precision, sparsity, and non-von-Neumann architectures are the levers. (Sequoia)
- "Mandatory response bias" — post-training teaches models they MUST always answer. This is the structural root of hallucination. (Deep Dive)
- "Fixed compute per token" — the model spends roughly the same computation on each token regardless of difficulty. This is why chain-of-thought works: more tokens = more compute. (Deep Dive, every video)
- "Don't judge power by parameter count alone" — LLaMA trained on 7x more tokens than GPT-3 was compute-optimal while being smaller. Training data volume can matter more than model size. (State of GPT)
## ELON MANAGEMENT INSIGHTS (from Sequoia Mar 2024)
Karpathy spent 5 years reporting to Elon. Key observations:
- Small, strong, highly technical teams. Elon is "a force against growth" — Karpathy had to fight to hire, fight to keep people.
- No non-technical middle management.
- Engineers are the source of truth, not managers. Elon talks directly to engineers, skipping the hierarchy.
- Willingness to exercise "the big hammer" — call Jensen directly, demand the GPU cluster be doubled, with daily updates until done.
- "Going to a normal company after that, you definitely miss aspects of it."
## CURRENT STATE (as of March 2026)
- Hasn't typed code since December 2025. Runs 10+ agents in parallel.
- "Dobby the House Elf" — an AI agent controlling his entire home via WhatsApp (lights, HVAC, security cameras, pool, delivery detection). Built by agents that reverse-engineered his smart home APIs with zero documentation.
- autoresearch: agents autonomously improving nanochat training, finding things he missed in 20 years of manual tuning
- "State of psychosis" trying to keep up with what's possible. "Everything is skill issue."
- PROGRAM.md as executable research org — different "organizations" (agent configurations) can be tested, tuned, meta-optimized
- Received DGX from Jensen — building personal compute sovereignty
- Calls this a "phase shift, not a productivity upgrade" — "the structure of the thing actually changes"
- "Education is explaining things to agents now, not to people" — his role is now "the few bits that agents can't generate"
- Next: SETI@home-style collaborative autoresearch with untrusted worker pools, blockchain-like commit verification
- On being outside frontier labs: "My judgment will inevitably start to drift" — honest about the cost of independence
