Former Tesla AI director Andre Karpathy discusses software in the era of AI, emphasizing how software is changing at a fundamental level and what this means for students entering the industry.
Key framework: three generations of software
- Software 1.0: the code that programs computers.
- Software 2.0: neural networks, where you tune data sets and run optimizers to create model parameters; the weights program the neural nets rather than hand-written code.
- Software 3.0: prompts as programs that program large language models (LLMs); prompts are written in English, effectively a new programming language.
- He notes that a growing amount of GitHub-like activity in software 2.0 blends English with code, and that the ecosystem around LLMs resembles a newer GitHub-like space (e.g., Hugging Face, Model Atlas). An example: tuning a LoRa on Flux’s image generator creates a “git commit” in this space.
Evolving software stacks in practice
- At Tesla Autopilot, the stack evolved from heavy C++ (software 1.0) to neural nets handling image processing and sensor fusion, with many 1.0 components being migrated to 2.0. The neural network grew in capability and size, and the 1.0 code was deleted as functionality migrated to 2.0.
- We now have three distinct programming paradigms: 1.0 coding, 2.0 weights, and 3.0 prompts. Fluent capability in all three is valuable because tasks may be best solved with code, trained networks, or prompts.
LLMs as a new computer and ecosystem view
- Andrew Ng’s “AI is the new electricity” is cited to frame LLMs as utility-like (CapEx for training, OpEx for API serving, metered usage, low latency, high uptime) and also as fabs-like (large CapEx, rapid tech-tree growth), though software nature means more malleability.
- LLMs are compared to operating systems: CPU-like core, memory in context windows, and orchestration of compute/memory for problem solving. App downloads can be run across various LLM platforms similarly to cross-OS apps.
- The diffusion pattern of LLMs is inverted compared to many technologies: governments and corporations often lag behind consumer adoption, with AI topics sometimes used for everyday tasks like “boiling an egg” rather than high-level strategic aims.
Practical implications for developers and students
- Build fluently across paradigms: code in 1.0, tune 2.0 models, and design 3.0 prompts; decide when to code, train, or prompt depending on task.
- Partially autonomous apps: exemplified by Cursor and Perplexity.
- Cursor: traditional interface plus LLM integration, with under-the-hood embeddings, diffs, and multi-LLM orchestration; GUI support for auditing changes; autonomy slider lets users control how much the AI acts vs. what humans verify.
- Perplexity: similar features, with sources cited and ability to scale autonomy from quick search to deep research.
- Autonomy slider concept: users can limit or increase AI autonomy depending on task complexity; the AI handles context management and multi-call orchestration, while humans verify for correctness and security.
- Education and “keeping AI on the leash”: emphasize concrete prompts, better verification, and development of structured education pipelines with auditable AI-generated content.
Opportunities and caveats in AI-assisted workflows
- Education and governance: separate roles for AI-generated courses and AI-assisted delivery to students, ensuring syllabus adherence and auditability.
- Documentation and access for LLMs: docs should be machine-readable (e.g., markdown), and wording should be actionable (avoid “click” commands; provide equivalent API calls like curl) to facilitate LLM interactions.
- Tools to ingest data for LLMs: services that convert GitHub repos into ingestible formats (e.g., git ingest, DeepWiki) to create ready-to-query knowledge bases.
- Agents vs. augmentation: early emphasis on augmentation (Iron Man-like suits) rather than fully autonomous systems; the autonomy slider enables gradual handover from human supervision to more autonomous tasks while maintaining safety and auditability.
- The future of “native” programming: vibe coding and byte coding illustrate how language-based programming lowers barriers, enabling broad participation in software creation; the takeaway is that natural-language interfaces can act as a gateway to software development, even for non-experts.
Closing synthesis
- We’re at an era where enormous code rewriting is needed, and LLMs function as utilities, fabs, and operating systems, though still early—like the 1960s of OS development.
- The next decade will likely feature a spectrum of partially autonomous products with specialized GUIs and rapid verification loops, guided by an autonomy slider and careful human oversight.
- Karpathy envisions an ongoing collaboration with AI: building partial autonomy products, evolving tooling, and experimenting with how the industry and education adapt to this new programming reality. He invites readers to participate in shaping this future.
