Why I still haven’t bought into true RSI

An “AI moderate’s” view on recent events and the trajectory of frontier models.

We’re in an era where a few organizations are using thousands of concurrent agents to improve their processes and output. These organizations happen to be just the frontier AI labs, in particular OpenAI and Anthropic. In the last few weeks, I’ve been pondering what it means for so many employees across these organizations to rapidly update their expectations for the pace of AI progress and associated risks.

A core perspective I have is that the frontier labs and broader frenetic, competitive culture in the San Francisco AI scene set up an environment that amplifies any AI concern. This has some benefits in causing more general audience awareness of AI, as fear sells, but exaggerating risk timelines or severity will have negative second-order effects. I remember many loud AI safety debates, and their associated clouds over the viability of open-source AI, in 2023 and 2024 — the primary risks then did not arrive in the forecasted timelines.

The general populace of these two key labs was very anxious about AI risks and the rate of progress even a year ago, and especially as agents got stronger product-market fit at the start of 2026. This cultural precondition, when exposed to the reality that thousands of agents will constantly be working fairly productively in your business, will only increase this anxiety. The step from this anxiety, and incidents like OpenAI-HuggingFace, to extinction risks feels very religious.

Richard Ngo had an apt summary of the situation:

Now a large proportion of the AI safety community is implicitly or explicitly orienting to futures where an intelligence explosion occurs within a few years. My default expectation (absent an extensive pause) is that a similar thing will happen: they’ll turn out to be directionally correct (relative to the expectations of almost anyone not linked to the community) but factually wrong. Specifically, we won’t have superintelligence within the next 8 years, but things will still be moving so fast that it’ll *feel* like the people who argued for short timelines were right.

… I wanted to say something now because it feels like the level of bandwagoning towards “singularity soon” is getting pretty wild.

Personally, I think this view aligns closely to what I outlined in my alternate scenario to true recursive self-improvement (RSI), which I called lossy self-improvement. A summary of this view is that:

1. Automatable research is too narrow to achieve a massive net acceleration in progress, in the face of scaling laws’ exponential costs,

2. Diminishing returns of more AI agents in parallel are real, &

3. Resource bottlenecks and politics are a major factor in building strong LLMs (and AI can do much less to accelerate this).

So, I’m left balancing the above, latent increase in the cultural temperature with the potential that the labs have seen genuinely scary, specific breakthroughs that are not public yet. My expectation is that more of the current AI safety concern is on the former – scaled agents working – but I hold high levels of uncertainty here. Foundational, imagination-based AI breakthroughs are the sort of thing that would make me update my RSI timelines from closer to a tool to sustain progress in the face of exponential costs (scaling laws), to something more unpredictable and/or unstable.

Some of the best recent resources on RSI have been Dwarkesh’s podcasts with Noam Brown and the trio of John Schulman, Beren Millidge and Charlie O’Neill. I have a few important reflections from both of them.

First, the podcast with Noam Brown made me internalize how big of a short-term acceleration mass inference capacity is. These labs will throw thousands of agents at important, measurable problems. At the same time, compute capacity available to them is going to continue to scale. I have my doubts that the labs can afford to spend a constant portion of this compute on internal R&D as the total volume goes up, especially with plans to IPO, as they face increased scrutiny on basic economics. It is important to not confuse massive steps in inference-time scaling, a dynamic which should be fairly predictable, with being the outputs of RSI, which is highly uncertain.

Second, the trio podcast debating the state of the art in technical capacities induced more of a surprising reaction that I haven’t fully settled. Through the first hour or so of this podcast, where they debate the role of RL, distillation, scaling, inference-time compute, etc., I found myself strongly agreeing with the distribution of claims. A TLDR would be that our current techniques work and let us solve problems we know how to state, but they don’t result in a magical level of generalization to unknown, harder problems in most partially verifiable domains (i.e. progress in math is an exception, rather than a rule).

The surprise of this podcast was the end, where they were predicting timelines for various thresholds of AI. I had GPT-6-Astra summarize the answers provided to three questions from Dwarkesh, of the form “when will AI reach X ability”:

All timelines are relative to the interview date.

• Drop-in remote worker for broad white-collar work over a month

  • Charlie O’Neill: ~1 year with programmatic access to workplace tools; ~2 years if it must operate through a browser. Means ordinary white-collar work, not highly creative research.

  • Beren Millidge: ~3 years for full generality; 80–90% coverage sooner. Main uncertainties: online learning and the long tail of tasks.

  • John Schulman: ~1 year for an “okay” version, with uneven capabilities that improve over time.

• 10× productivity uplift for AI researchers

  • Charlie O’Neill: 5–10 years. Bottleneck: absorbing information and deciding which experiment to run next.

  • Beren Millidge: Finds John’s ~2-year estimate plausible, but gives no independent timeline. Assumes AI can run successive experiments and learn from feedback; other bottlenecks would remain.

  • John Schulman: ~2 years.

• AI surpassing top human experts across all computer-based work, including multiyear projects (“ASI”)

  • Charlie O’Neill: 5–10 years. Highlights limitations in memory and context length.

  • Beren Millidge: ~5 years for areas labs focus on; potentially longer for literally every domain. Gives no firm timeline for the universal version.

  • John Schulman: 3–4 years. Spatial/physical fields may take longer; requires onboarding and solving longer-horizon learning.

Roughly, a recurring problem when discussing RSI is a lack of specification in intelligence. The jaggedness of intelligence means that we need to discuss thresholds in specific, measurable tasks. The nature of LLMs’ intelligence is shaped very differently than humans, and the roles we forecast are human-shaped. AIs, therefore, do not cross these thresholds like remote worker or AI researcher discretely. It’s a slow diffusion, and a form of long tail will always exist.

Take the case of productivity of AI researchers. Many people under-index how much of science is communication and standard setting with colleagues. I do buy the cycle of experiment design and testing being 10x faster in the near future, but not hypothesis generation and intuition building. Accelerating understanding will be the key bottleneck – and it is one that despite all of the AI tools getting massively improved, humans will only improve marginally in their capability. A big improvement in the nature of science will be enabling humans to invest more time here, not them becoming exponentially better at it.

This links back to the Noam podcast. Agent swarms in the near future will be effective at solving clear, open problems with verifiable answers. In this vein, when it comes to improving AI models, RSI is much more helpful at efficiency rather than expanding peak intelligence. This is due to the fact that LLM serving has clear metrics you want to improve that are measurable and malleable. This’ll enable better inference-time scaling and more efficient multi-agent systems.

Still, I cannot get past the fact that all of our scaling laws show that you need exponential compute and resources to make linear improvements in intelligence. RSI is poised to make modern LLMs vastly cheaper. Trends that have shown LLMs get exponentially cheaper at a given intelligence are likely to accelerate. A crucial factor for the labs will be increasing margins as revenue could potentially have negative pressure if there’s fierce competition in lowering prices at a fixed intelligence level — Jevons paradox will likely prevail, resulting in strong businesses.

RSI factors will have a much harder time improving pieces of the LLM puzzle like managing complex post-training recipes. There were a few quotes from John Schulman that I strongly agree with on the state of post-training at the labs:

If I think about a post-training team and why you need a lot of people on the team, it’s just because there are a lot of different areas where you have to figure out how the model should behave. It would be very hard to automate the whole thing, just because someone has to think about how the model should behave in this area.

and later:

It’s really easy to screw up post-training in some way that doesn’t show up in benchmarks.

These tasks are uniquely hard for current LLMs. Yes, they’ll get better as the industry is still rapidly scaling RL environments related to these domains, but this paradigm does not last forever. In the near future, it could become exponentially harder to conceive, build, and test new environments that meaningfully challenge the leading LLMs – these hard environments are the ones that are crucial as a learning signal in RL.

OpenAI and Anthropic have shared a good amount of internal measurements related to RSI, and my current read is that the biggest takeoff in automation within the labs is in tasks like software engineering, monitoring logs, managing planned experiments, and other fairly routine (but not always easy) tasks. For example, I was surprised by this language in the recent Claude Fable 5.1 & Mythos 5.1 System Card:

We believe that internal usage of recent AI models has been a key factor in maintaining the current rate of progress, but we do not yet see clear signs of dramatic acceleration beyond that rate.

Altogether, I think the hardest exponential we are fighting is on peak intelligence. That is the hardest one to budge or even accelerate. Still, my mental model for the very early innings of RSI is more of massively scaling and diffusing inference-time compute to AI research and related activities, which has a large amount of low-hanging fruit available. This, on its own, is still poised to be economically transformative. It may also unlock more resources to push on AI diffusion, which is the crucial bottleneck in unlocking much of the potential benefits of AI.

For now and until more evidence emerges, lossy self-improvement remains my baseline on the trajectory of progress, and the increased discussion of extinction risk seems very misplaced. As always, things can change fast in AI.
