AI researchers debate how close we are to recursive self-improvement

New episode with John Schulman, Charlie O’Neill, and Beren Millidge. I got together with some of the most insightful AI researchers I know who are at the openish companies, because I wanted to hear the details of what's actually happening at the frontier and what comes next.

As agents generate more and more of your software, the bottleneck shifts from your engineers actually writing code to verifying it. Antithesis does that testing for you. Ron Minsky, who co-leads Jane Street's tech group, told me that Antithesis was able to help his team shake out bugs in software that had already undergone heavy review. If you want to see how it fits into your development process, go to https://antithesis.com/dwarkesh * Jane Street just launched its most ambitious competition yet: design a protocol-emulator ASIC. Basically, if you have a chip you want to test outside of a live system, you should be able to connect it to your design and have it simulate realistic traffic. Jane Street wants general-purpose, reprogrammable designs that can work across multiple protocols and remain useful as new ones emerge. The most novel submissions will actually get taped out, and the winners will receive a physical copy! The competition is open until January 18, 2027, and teams are encouraged.

My team uses it as a producer: whenever my editor posts a rough cut of an interview in Slack, Grok Bot opens the transcript on its own computer, matches my notes to the exact moments they refer to, and uses a file of my preferences to suggest edits. Then it sends me its top clip candidates so I can review everything from my phone, which saves my editors from sorting through hours of footage.

    Steelmanning the case against recursive self-improvement (RSI): why progress might stall

    Dwarkesh opens by asking what technical reason could prevent a “2036 superintelligence world.” The guests argue for several stall modes: repeated hype cycles that hit practical bottlenecks, persistent gaps in judgment/verification, and the possibility that current deep learning recipes are far from the global optimum.

    • Moravec’s-paradox-style worry: impressive benchmark wins without proportional real-world impact
    • Persistent bottlenecks: weak model judgment, self-checking limits, and verification overhead
    • The “AGI feels dumb after a month” cycle may repeat many times
    • RSI may require a new discontinuity beyond transformers + RL that current systems might not discover
  2. 7:07 – 14:39

    Paradigm shifts vs optimization: the hard part is choosing objectives, not hill-climbing them

    The conversation distinguishes between research with crisp objectives and open-ended science where the objective itself is unclear. They revisit early skepticism that next-token prediction would yield intelligence—and how surprising generalization keeps overturning confident priors.

    • Objective-specified ‘auto-research’ differs from open-ended paradigm-shift science
    • Early OpenAI intuition: log-loss wouldn’t emphasize “important bits,” yet it worked anyway
    • Generalization is the engine of progress—and hard to predict in advance
    • Automated “thinking time” could speed up analysis/theory, but may not find the right objectives
  3. 14:39 – 17:24

    What remains hardest to automate in AI R&D: asking the right questions, taste, and alignment/specification

    Dwarkesh asks what the last human-held pieces of the AI R&D pipeline will be. The guests converge on objective specification—deciding what we want and how models should behave—plus the research taste needed to choose experiments and interpret results.

    • Models can increasingly execute experiments, but struggle to propose the best next experiments
    • Long-lasting human role: specifying objectives (RLHF goals, constitutions, model specs)
    • “Alignment is the final job” reframed as specification + optimization of objectives
    • Post-training is hard to automate because desired behavior is high-dimensional and domain-specific
  4. 17:24 – 18:30

    Sponsor break: Antithesis and the verification bottleneck for AI-generated code

    A short sponsor segment argues that as agents write more code, verification becomes the limiting factor. Antithesis is presented as a way to surface hard-to-find bugs and speed up engineering by increasing confidence in correctness.

    • As code generation scales, human review/testing becomes the bottleneck
    • High-assurance teams still miss subtle bugs; better testing accelerates delivery
    • Verification tooling complements agents by reducing risk of regressions
    • Call-to-action: integrating Antithesis into development workflows
  5. 18:30 – 28:05

    Why Chinese labs are catching up: distillation, router data, and realism vs benchmark environments

    Dwarkesh asks why model providers aren’t consolidating and what drives Chinese labs’ rapid progress. The group emphasizes distillation, the importance of prompt distributions (including router/proxy data), and a key axis tradeoff in training: difficulty vs realism.

    • Distillation counteracts centralization: behaviors learned via RL can be copied with few bits
    • Prompt distribution is the hard part of distillation; “realistic prompts” matter
    • Router/proxy services can supply high-value real-user prompt data for distillation
    • Benchmark difficulty isn’t enough: realism-heavy environments are needed for robust agent behavior
    • Post-training is fragile; small “knob turns” can create quirks that benchmarks don’t detect
  6. 28:05 – 33:50

    How automated AI researchers will likely be trained: patching weaknesses with feedback + research-project environments

    The guests outline a practical training recipe for “AI that can automate AI R&D.” Rather than a clean from-scratch self-play story, they expect iterative cycles: researchers use models, notice consistent weaknesses, then patch them with human feedback and synthetic multi-step research environments.

    • Training recipe: combine learning from researcher feedback (“taste”) with practice environments
    • Iterative development: each generation targets what was most broken in the last
    • Compute bottlenecks favor staying near the frontier and ‘diffing’ recent improvements into training
    • Distillation alone can’t surpass humans, but harder environments can push beyond human ability
    • Research often proceeds via intuition-guided task design, not direct optimization of final objectives
  7. 33:50 – 38:48

    Will long-horizon RL produce general-purpose workers? The RLVR bet and what it’s actually for

    Dwarkesh articulates the ‘big bet’: scaling RL with verifiable rewards (RLVR) across millions of environments to produce persistent, long-horizon agents. The group debates whether this primarily serves RSI or revenue, and why labs still train lots of domain-specific capabilities if in-context learning is supposed to generalize.

    • RLVR across diverse domains aims to train persistence, context triage, and multi-agent coordination
    • Labs may be optimizing both for RSI and for commercially valuable deployments to fund scaling
    • Domain-by-domain strengthening (coding → finance → office tooling) appears to be working
    • Even if models can learn on the fly, baking skills into weights can reduce runtime cost
    • Sim-to-real is powerful but has weaknesses for tasks involving many humans and messy realities
  8. 38:48 – 1:00:33

    The sim-to-real gap and the ‘hive mind’ vision: learning from deployment runs into incentives and continual-learning failures

    Dwarkesh presses on why massive inference/deployment data isn’t immediately improving models via continual updates. The discussion covers partial forms of learning-from-deployment (mid-training, specialization modules), economic reasons companies resist sharing data, and technical issues like catastrophic forgetting in frequent small updates.

    • Deployment data already feeds next-gen training indirectly, but tight online learning is hard
    • Incentives: firms may not want model providers to learn from their proprietary deployments
    • Likely path: specialization modules (LoRAs/cartridges) → trace generation → later consolidation
    • Micro-updates cause forgetting and general capability degradation; RL is gentle but limited in what it can change
    • Long-horizon real-world tasks may require real-world interaction data, not just datacenter simulations
  9. 1:00:33 – 1:17:47

    How much progress is ‘just data’? Pretraining efficiency, post-training bits, and the environment ladder problem

    They examine whether current architectures could become superintelligent with the right data, and how far data improvements can continue. The guests argue that pretraining data gains are real but limited, while post-training requires scarce “new bits” and increasingly expensive environment curricula.

    • In principle, a dataset/environment ladder could train human-level AI researchers—but each rung may get harder to build
    • Pretraining low-hanging fruit is being exhausted; internet growth doesn’t guarantee more high-quality signal
    • Empirical claim: data improvements can dominate compute-efficiency gains at small scale (with caveats)
    • Post-training needs new signal not present in raw web data; filtering won’t conjure frontier math proofs
    • RL struggles with exploration; large gaps between curriculum rungs can prevent progress entirely
  10. 1:17:47 – 1:24:55

    Why RL is working better than expected: mid-training warm starts, higher signal-to-noise, and horizon generalization

    A year ago, many expected RL to be too low-bandwidth to scale; now it seems to drive big capability gains. The guests explain this by pointing to strong mid-training that gets models most of the way, RL’s unusually clean signal, and generalization in “ability to keep going” over longer horizons.

    • Mid-training on synthetic reasoning often delivers most of the gains before RL fine-tuning
    • RL provides high signal-to-noise by focusing updates on correctness, not imitating full traces
    • Compute + large group sampling can reliably surface correct solutions to reinforce
    • Observed ‘horizon generalization’: models get better at sustained long tasks even out of domain
    • Qualitative jumps can emerge from many discrete ‘quanta’ improvements averaged across tasks
  11. 1:24:55 – 1:28:29

    Move 37 vs entropy collapse: creativity, exploration limits, and emerging model monocultures

    Dwarkesh asks whether RL on LLMs will yield “Move 37”-style creativity. The guests argue that some creativity is already visible, but also warn RL and distillation can reduce output diversity, induce stylistic tics, and create a monoculture—often due to narrow judges/verifiers and limited environment diversity.

    • Move 37 depended on stronger exploration (e.g., MCTS); policy-gradient RL explores less
    • Creativity can mean hard search under constraints—AI can excel there if trained
    • RL/distillation can reduce diversity and produce repetitive tics (“entropy collapse” symptoms)
    • Distillation from a single teacher can spread stylistic quirks across the ecosystem
    • Many failures are blamed on narrow verifiers/judges rather than RL as a fundamental method
  12. 1:28:29 – 1:37:01

    Rapid-fire timelines: remote workers, AI R&D productivity multipliers, and ASI forecasts

    The episode ends with fast predictions: when models feel like month-long remote workers, when AI researchers see 10× productivity, and when systems dominate top human experts across computer-based work. Disagreements hinge on definitions of “general worker,” long-horizon learning/memory, and the long tail of neglected domains.

    • Remote-worker-level agents: estimates range from ~1–3 years depending on scope and tooling
    • Key blocker for research speedups: absorbing information and choosing optimal next experiments
    • 10× AI-researcher uplift: guesses around ~2 years (with skepticism about scalar metrics)
    • ASI across all computer-based domains: ranges from ~3–4 years to ~5–10 years
    • Long tail concerns: domains with little data, complex onboarding, and long-horizon memory needs
