Import AI 474: Platonic mindspace; TPUs in space; Zhipu starts an outer RSI loop

Michael Levin proposes that minds are patterns from a Platonic space that interface with bodies and machines, suggesting non‑physical models of mind. He cites synthetic biology experiments like xenobots and anthrobots, and algorithmic perturbations that reveal emergent behaviors. Stanford researchers Perry Dong and Chelsea Finn argue robotics lacks a post‑training recipe analogous to language models, proposing the EXPO(-FT) algorithm for fine‑tuning large robotic models.

Are minds patterns from a Platonic space, with bodies and machines as their interfaces, Michael Levin asks: …A mind-bending paper asking us to reconsider basic assumptions about philosophy and biology… Could the complexity in the world around us be better explained by there being a platonic zone of patterns of arbitrary complexity which seek to embed themselves in the world? That’s the big question at the heart of an iconoclastic paper from scientist Michael Levin.

The argument: “I argue that the emerging sciences of synthetic morphology and diverse intelligence suggest non-physicalist models of mind and show how they can be empirically investigated… I propose that the relationship between mind and brain is the same as the relationship between mathematical patterns and the morphogenetic outcomes they guide (more broadly, mind:body is as math:physics)”, he writes. “Bodies (whether living, engineered, or hybrid) are interfaces for a massive, multi-scale hierarchy of patterns to ingress into the physical world… specific patterns represented by biophysical, biomechanical, or chemical information fields serve as encoded setpoints for homeostatic or allostatic processes—in other words, goal states toward which systems try to navigate in various problem spaces”.

How It Works & Technical Architecture

What does robotics need? “An algorithm built specifically for fine-tuning frontier robotics models, one that stays stable when applied to models with billions of parameters, and that learns from a small enough amount of experience to be practical on real hardware”, they write. Along with this, they need to converge on “a set of standard practices surrounding the algorithm. A default way to define what counts as success. A default way to reset the scene between attempts, so the robot can try again. A default way for a person to give feedback, and to turn that feedback into learning”. In the post, the researchers talk about a specific algorithm, EXPO(-FT), that they’ve been developing for robots which they think embodies some of these qualities, though it’s early in its development and not widely used. “EXPO(-FT) works by learning to repeatedly improve actions from the frontier model using reinforcement learning with small edits from a lightweight policy, and then absorbing that into the frontier model itself.”

Feedback must be sufficiently local : “It should be tied to specific engine launch parameters, code changes, kernels, input conditions, threads, execution intervals, or code paths, helping the agent narrow the scope of the problem.”

Deployment & Availability

Feedback must support objective verification : “Whether a change is correct and whether performance has improved should be determined by reference implementations, test results, and comparable experimental metrics.”

Strategic Perspective & Ecosystem Impact

Towards a platonic realm of arbitrarily sophisticated patterns: “We already know that non-physical patterns ingress into, and functionally matter, in the non-living and living world and that we can (and do) study them to great effect… platonic forms inject information and influence into physical events, such as the growth and form of biological bodies,” he writes. “This latent space [of platonic forms] contains not only low-agency forms such as facts about integers and geometric shapes, but also a wide range of increasingly high-agency patterns, some of which we call ‘kinds of minds’. Thus, I propose that minds, as patterns that ensoul somatic embodiments, are of exactly the kind (but not in degree) of non-physical nature as the patterns that inhabit and guide the behavior of simple physical structures.”

Some bizarre experiments: There aren’t any home-run experiments that back this up, but rather there are weird things in the world that suggests that even seemingly simple systems are able to explore and expand into rich patterns that seem to be adjacent to them in this hypothesized platonic space of complexity, yet not implied by the systems themselves. A couple of nice examples here are xenobots, which are biorobots made of frog cells and “teach us about patterns adjacent to those of frog embryos”, and anthrobots which are made from human tracheal cells and when taken out of the body take on bizarre new forms and display interesting behaviors like being able to autonomously heal damage to neurons and “which teach us about patterns adjacent to adult human tissues”. There’s also an amazing discussion of an experiment where they take a standard sorting algorithm and perturb it in a few ways, including ‘locking’ certain cells in place and noting that it then routes around those cells, and a more complex experiment where they let each number run a different type of sorting algorithm and then study how different families of sorting algorithm appear and then cluster together in numberspace during the sort - this kind of complexity is unexplained and not anticipated by staring at these algorithms in the abstract, but by embedding them in a complex system they suddenly take on new properties. “Machines (whether meaty or silicon-based) also do other things that are not in the algorithm, as do we, and these things are not just unpredictable complexity, it is intelligence and other components of minds. It is those behaviors—allowed by the algorithm but not directly prescribed by it—that correspond to the freedom (physically non-determined) or secret sauce that we seek when trying to understand how free minds can supervene on chemically determined substrates in the case of living beings,” he writes. “On this view, algorithmic machines and biochemical life are on exactly the same spectrum, having in common the ability to go beyond the facts of physical or algorithmic implementation because both are just pointers/interfaces to patterns that ingress in a way that results in getting more out than we put in.”

Why this matters - perhaps the ‘minds’ of AI and of humans are close but not exactly the same in platonic mindspace : The research agenda Levin lays out is intoxicating and fascinating and also seems to me to hold some clues as to how we might grapple with the deep philosophical and alignment questions inspired by AI systems. Perhaps both human minds and different types of AI minds are neighboring forms in this space, and brains and datacenters are different bio- or anchor-systems in the physical world that their shadows fall on? Could we be but vessels colonized by patterns from another place? Could it be “possible to re-cast the theory of evolution as a process in which agential patterns seek embodiments”? “Is there a “force”, beyond the “if you build it, they will come” model of physical objects, pulling patterns from the space? Or are the contents of the Platonic space under “positive pressure”, somehow encouraging their appearance in the world as intrusive thoughts, archetypes, works of art?... The only thing that can be said strongly at this point is that our ignorance about the capabilities of matter, together with the patterns that ingress into specific architectures, is vast”. Make yourself a bucket of coffee and spend a few hours with this paper - it’s worth it.

Why it matters

If minds are non‑physical patterns, AI alignment and safety may need new theoretical frameworks. A reliable post‑training recipe could accelerate practical, robust robotics.
