One of the most interesting unsolved problems in RL is how to train directly on production traces.

We know how to do this reasonably well when the feedback is instructive or prescriptive: distill from a strong teacher that can look at the trace and tell the model what it should have done instead.

But a lot of the most valuable production feedback is evaluative: did the task succeed, what score did it get, did the user accept the result, etc.

Normally you would train against this kind of feedback with environment replay (e.g. GRPO): rerun the policy, sample multiple trajectories, and optimize against their relative rewards. The problem is that for many real production traces, you can't recreate the exact environment state that generated the trace.

That's what makes algorithms like Flash-Reinforce, SAO, and BPCO so exciting – they point toward learning from one trajectory per prompt without needing to recreate the environment and generate a fresh group of samples.

If these methods work at scale and on real production workloads, they could become an important building block for continual learning

X post by Rhythm Garg on training RL directly from production traces with evaluative feedback, naming Flash-Reinforce, SAO and BPCO as methods that learn from a single trajectory per prompt without environment replay, as a building block for continual learning.

random criticisms of model arch hypes:
1. Continual learning - My problem isn't even architectural. It can be done, and I am even working on this! It's much stupider. Data preprocessing and curation is alr very bad w current LLMs. It will get be much harder to effectively make use of more neuroplastic and brittle weights at scale w current data methods. The good thing about scratchpads is that they are legible and inherently interpretable. You can just read them to debug, and most people don't even do that. If u put evolution in the weights layer, you have to be much more disciplined with context and scratchpads, to a level much less fault-tolerant than current data pipelines (assuming sample efficiency holds constant which it wouldn't be, tho).

2. World models - Generally it is not clear to me which the proposed video model architectures are necessary for AGI takeoff. At the limit yes, humans consume photons and there are way more photons than text. But at the limit we don't know what is optimal, and this is generally not the argument being made! The argument is often a more fundamental view of text being insufficient in some way to model the world, and I do argue that current LLMs already know and do far more than the average college grad could!

Dark-mode tweet by Minh Nhat Nguyen with two criticisms of architecture hype: continual learning as a data-curation problem (scratchpads are legible, weight-level updates less fault-tolerant), and world models/video architectures not clearly necessary for AGI takeoff.

OX ALPHA MAY BE A CONTINUAL LEARNING MODEL

I've seen multiple posts showing it getting better every day. But OpenRouter says the model "retains prompts and completions but does not use them for training"

So there are 3 possibilities:

1. the provider is rapidly post-training and quietly deploying better checkpoints

2. a continual feedback loop where real world failures are discovered from usage, trained on, and pushed back into prod. the prompt aren't directly training the model, but they expose areas that need fixing

3. ACTUAL ONLINE LEARNING: the most interesting possibility. this is what many have speculated would be SSI's first launch, where the model is genuinely updating from live usage. as interesting as it is, we don't know for sure if this is exactly SSI's plan, or if this model is SSI's first release. just putting this out there.

None of the 3 seem more likely with the current evidence. But if Ox Alpha is really improving every day, giving it away for free for 1 week was the smartest move they could've made.

Tweet by @Hesamation speculating that a model called Ox Alpha, served on OpenRouter, is improving daily and weighing three explanations (rapid post-training, a feedback loop, or true online learning possibly tied to SSI), noting none is clearly favored by current evidence.

agents are godlike at math, but can't update an invoice for a customer without fucking it up.

what does this tell us about reality? about humans?

imo something like..... general intelligence is very real and very powerful, but 1. domain specific intuition can get you *incredibly* far and 2. even very powerful general intelligence can be blocked by inherent lack of basic training and expertise in a domain

imo a lot of what we think of as general intelligence is *capability to learn and acquire new skills*, and models do this exclusively ~offline or in context. if we had continual learning / ways to train intuition on the fly across multiple tasks invoices would look v different

Twitter thread discussing why AI agents can be extremely capable at formal domains like math while failing at mundane tasks like invoice updates, with replies proposing that general intelligence is real but bottlenecked by lack of continual/on-the-fly learning and domain-specific intuition.

Adi @adi_baradwaj · 6h "I've been fascinated by @RichardSSutton's approach to AGI with @oaklab_ai It's distinct from the other neolabs in a number of ways. As far as I can tell: - Zero pretraining, all learning is continual learning via RL at runtime - The system learns to extract features and define subproblems, computes intermediate value functions for these subproblems, and then updates the policy via value iteration - Feature discovery is done via generate-and-test (i.e. random search) or "Continual Backprop" which is basically backprop + generate-and-test Some open questions: - Having a good reward function is of course a huge part of the puzzle, and it's not clear to me if OaK has a good answer for this? - The press coverage claims that their goal is a 1-trillion-param agent that can learn and plan on 20W. Presumably this is just because it's an online algorithm with no pretraining, I don't see why the learning step itself would be any more energy efficient? - Unclear to me what function approximator they're using for the value function and how they're performing updates" [embedded image: slide titled "How OaK creates a subproblem from a feature i, κ" from a "Reinforcement Learning Conference" talk, showing bullet points defining i = feature number, κ = how intensely we want the feature (balanced against losing reward), the subproblem is to drive the world to a state where the feature is high without losing too much in terms of reward, "Find an option π, γ that maximizes the value of the ith feature at termination while respecting rewards and value", a math expression, and a photo of a speaker (older man in patterned shirt) at a podium.

[Repost indicator] Mert Cemri reposted Alex Dimakis ✓ (@AlexGDimakis) — 5h I am very excited about this research: We show 2 things: 1. If you just do random sampling (i.e. you try to solve a problem k times independently, and keep the best) your ELO scaling will be linear in log(test-time-compute). Agents like Claude-Code and Codex scale like that after a few hours. 2. We compare human expert coders to coding agents on the same tasks (from AtCoder Heuristic Contest). The exciting finding is that humans scale super-linearly. This is evidence that humans do continual learning, while they are solving a problem! I.e. they learn more about the coding problem they are trying to solve and scale fundamentally better compared to randomly trying things in a memoryless fashion. This is empirical evidence that supports what many of us have felt for a while: unless we solve continual learning we will not be able to outperform humans in tasks that take many days. Current coding agents are not able to do this. > QUOTED: Qiuyang Mang ✓ (@MangQiuyang) — 9h > (1/n) New blog from UC Berkeley, UW, and Princeton: Who scales better in long horizon: AI coding agents or top coders? > We compared modern agents to top human ... > [Embedded chart: "Human vs Agent" — Y axis "Elo Rating" (1000–1800), X axis "time" (1h to 7d).

[repost icon] Machine Learning Street Talk reposted Kenneth Stanl... @kenneth0stanl... · 12h Difficulty achieving continual learning is also a bad omen for creativity: what you can imagine is naturally a function of what you can learn. Both are mediated by the adjacent possible to the same internal representations! Contorted algorithms (or the absence of clean options) for what should be simple and straightforward continual learning are therefore a hint that the large models they serve are creatively barren. That explains why something that is close to "knowing everything" and often competitive with the abilities of experts can still produce fewer breakthroughs than you would expect from a human with similarly astounding knowledge and expertise.
Note from Claude Sonnet 5

Kenneth Stanley (known for open-endedness/novelty-search research) argues that difficulty with continual learning in LLMs signals limited creativity, since imagination and learning share the same substrate of internal representations. Relevant to Nathan's interest in architecture/learning-dynamics questions (brain_graph_1) and to broader questions about what current LLMs are missing relative to humans.
