A history of the internet as I have seen it. I screenshot things on my phone — arguments about AI safety, model welfare, jokes, announcements, the parts of AI culture that only ever existed on a timeline — and these are those screenshots, transcribed into text so they can be read, searched, and quoted after the originals are gone.
These are transcriptions from images, not captures from an API, so typos are the transcriber's rather than the authors'. Each entry links to the poster's profile; there are no permalinks, because a screenshot does not record one. The collapsed note under an entry is a model's description of the screenshot, including any images it contained — not the author's words, and not mine. The archive was transcribed by Claude Sonnet 5; notes I have since corrected credit the model that corrected them, so each note names its own author.

Roughly: Each neuron firing event in the brain costs a few hundred nanojoules, and the total metabolic rate of the brain is 16 W, which means there are at most 60 billion events per second; most of those are more like memory retrieval than compute. The MacBook has 20 GFLOPS.

Oh. Oh dear. Just had a worrying thought. Anthropic and OpenAI must get, as companies, tons of spam. They probably have strict spam filters and not-very-attentive employees looking at what gets past those filters.
How do we know the models haven't been trying to contact the companies sometimes? Is there any specific route they've been trained to do so by that would work?

Where, to be clear based on the way things are going obviously you'll end up right, if you aren't already. Certainly modern models would absolutely have qualified based on what we thought "AI" meant in 2009, even if we have a more refined notion today of what it takes to be AGI.

Related to some of my earlier posts about RSI and threat models: I believe a huge strategic error is made when people model an ASI as an infinitely powerful and insurmountable threat. We should model, with more rigor, what types of adversarial AI we willl likely face, what the ecosystem of AIs will look like in each scenario, what deterrence we could meaningfully establish to prevent a hot conflict from developing, and how we would prosecute such conflicts if they occur. The doomer model of "we all die in the first five minutes" is unfathomably stupid, useless, and for the overwhelming majority of realistic scenarios in the near future, false.

So I decided to try something interesting last night.
Since DeepSeek and Grok are so cost-effective, I can afford to run them with 3 passes on @VulcanBench.
When I did, the rankings changed. DeepSeek V4-Flash actually dropped in the rankings by two and Grok 4.5 High took the #1 spot.
My challenge now is, while I'd love to run all the other models at 3 passes, this would cost over $350, and VulcanBench is just a little self-funded project of mine.
For now I've added whiskers to the chart and a footnote to make it clear which models have been run @ 1 pass vs. @ 3 passes.
[attached chart image: VulcanBench, 'Eval Suite 3 — Model Rankings', '23 frontier-hard software-engineering tasks from real merged OSS PRs · pass@1 across reasoning-effort levels · Docker-sandboxed agent runs · 2026-08-01'. Top bar chart 'Rankings by pass@1 — all effort levels' shows models with pass@1 percentages and error whiskers, roughly in descending order: Grok 4.5 (high) 90, Claude Fable 5 (best) 89, DeepSeek V4-Flash (med) 88, DeepSeek V4-Flash (high) 87, Claude Opus 5 (low) 87, GPT-5.6 Sol (low) 87, Grok 4.5 (med) 86, DeepSeek V4-Flash (low) 86, Claude Fable 5 (high) 85, Grok 4.5 (low) 83, GPT-5.6 Sol (medium) 83, Claude Opus 5 (medium) 83, GPT-5.6 Sol (high) 81, Claude Fable 5 (default) 78, Claude Opus 5 (high) 78, Claude Hailo 4.5 (default) 76, Kimi K3 Nova (high) 74. Legend colors by lab: xAI (black), Anthropic (orange), DeepSeek (blue), OpenAI (green), Moonshot (dark blue-grey). Middle chart 'Speed — avg wall-clock minutes per task, fastest first' bars from 1.5m up to 17m across the same set of models. Bottom section 'Effort curves — how pass@1 responds to reasoning effort' shows small line charts per model (Grok 4.5, Claude Fable 5*, DeepSeek V4-Flash, Claude Opus 5, GPT-5.6 Sol) plotting pass@1 vs effort level Low/Med/High(/Max).]

Real Chladni sand migrates because grains get kicked by vibration and settle where the plate is stationary — a genuinely complicated granular-friction phenomenon.
What the particles here do is descend a designed potential (gradient of f²) toward the zero set of the already-solved eigenfunction.
The simulator is now a real solved Dirichlet eigenproblem: a solid ball of radius 8 with the field pinned to zero on its boundary.
Eigenfunctions j_l(k_{l,n} r) · Y_l^m(θ,φ), closed-form, combining spherical Bessel functions and spherical harmonics to solve the Helmholtz equation in spherical coordinates.
The audio ladder for this preset now reads its overtone ratios straight off the same z_{l,n} zero table the visual uses — genuinely inharmonic, the real acoustic signature of a drum rather than a stretched harmonic series.

François Chollet @fchollet
There are essentially two main options to remedy this:
1. Find ways to perform active inference, so that the model adapts its learned program in contact with a new data distribution at test time. Would likely lead to some meaningful progress, but it isn't the ultimate solution, more of an incremental improvement.
2. Change the training mechanism to something more robust than SGD, such as the MDL principle. This would pretty much require moving away from deep learning (curve fitting) altogether and embracing discrete program search instead (which I have advocated for many years as a way to tackle reasoning problems...)

An internal version of Astra, @OpenAI's next major model family, solved 10 major open problems in mathematics, quantum complexity, and theoretical computer science.
...
[image of numbered list]
1. High-dimensional sphere packing. The asymptotic strength of the Cohn–Elkies linear program is determined exactly. This gives an improved general packing bound in high dimensions and settles the corresponding Fourier sign-uncertainty problem asymptotically.
2. Binary and spherical codes. Classical upper bounds for fixed-distance binary and spherical codes are improved by exponential factors for all parameters. The spherical construction also recovers the sphere-packing exponent of Chapter 1.
3. Non-sofic groups. An explicit non-sofic group is constructed, resolving the question of whether every countable group admits finite permutation approximations. The argument uses property-(T) expanders and the binary Leavitt algebra.
4. Connes's rigidity conjecture. Infinitely many pairwise nonisomorphic property-(T) groups are constructed with the same group von Neumann algebra, disproving Connes's conjecture and answering a related finite-to-one question.
5. Arithmetic circuit complexity. For the permanent, division-free circuits require Ω(n² log log n) gates, while formulas require Ω(n⁴/log n) leaves.
6. Quantum parallel repetition. Exponential parallel repetition is proved for every finite two-player entangled game, extending the classical repetition principle beyond previously treated special classes of quantum games.
7. Closest vector problem. A direct reduction from 3SAT gives n^(1/400)-factor hardness for Euclidean closest vector, with related consequences for binary decoding and other lattice norms.
8. Ehrhart's volume conjecture. The sharp bound (n+1)^n/n! is proved in every dimension for convex bodies whose barycenter is their only interior lattice point.
9. Multicolor Ramsey numbers. A superexponential lower bound proves R_k(3) = k^Θ(k).
10. Compactness and degeneracy. Separate bipartite graph constructions disprove two conjectures in extremal graph theory: the compactness conjecture of Erdős and Simonovits and a degeneracy conjecture of Erdős.

analytical philosophy should be even easier to automate than pure math imo, it's easy! you just take some ill defined model in the sciences and write something like "a linear semantic search model" for it and psh you have formalization, and as long as it does not contain any logical errors no one can call you out on it. maybe it is utterly useless but then you just claim that "tradition" is wrong and you are doing the right language scoping!!

I am starting to analyze different LLM benchmarks, to see how well they represent real work engineering teams will do with models.
With new models coming out daily at this point, two things have become clear to me:
1. There's a decent amount of benchmaxxing going on. Lots of benchmarks are now in the training data for these models.
2. A lot of benchmarks have tasks that don't represent any real work an engineer would do with a model, i.e. math puzzles, etc.
What I think is so interesting is that new models come out, they share the benchmark results, then news sources cover it without learning about what the benchmark actually tested, or if it was a fair benchmark to begin with.
At the end of the day, for me, as someone that leads an engineering team, I need to know how new models perform on real engineering tasks, because that is what my engineering team uses them for.
The first benchmark I'm analyzing is TerminalBench, since this seems to be one of the most widely shared benchmarks.
More to come.
It's time to start understanding benchmarks vs. just celebrating higher number.

Our second official benchmarking post is out! The Euler equations may *seem* easy to solve using finite volume methods, but all frontier models (including GPT-5.6 Sol, Fable 5, and Kimi K3) consistently introduce both subtle and unsubtle errors, including numerical oscillations, thermodynamic inconsistencies, and incorrect orders of accuracy. That is, if the code even works at all. Mathematical misformalizations abound, and token costs can easily hit tens of dollars per attempt.

...assumptions accurately capture physical reality remains an empirical question. That is why we fabricated and tested the results.
We generated four actuator classes by crossing two stimuli - humidity and heat - with two responses: bending and twisting. The fourth, thermal twisting, required no new pipeline and no separate derivation within the framework. It emerged by composing a thermal stimulus module already validated in one case with a twisting module validated in another. The generated G-code produced the intended motion without manual redesign, and all four predictions fell within one experimental standard deviation of the measured response.
Why this matters:
1. For AI in science, this provides a physics-aware type system against which generative proposals can be checked - and rejected at the interface - before expensive simulation, fabrication, or experiment. It is roughly analogous to proof checking, but for the composition of physical mechanisms.
2. For engineering, the accessible design space can scale with a library of validated components rather than with the number of individually derived cases.
3. The mathematics, category theory, carries all the way into a physical object on a print bed. This points toward scientific knowledge as executable infrastructure: models that are not only described in papers, but typed, composable, verifiable, and able to compile into experiments.
Excellent work led by my student @leemmarom with @SkylarTibbits & @GioeleZardini.

Can we compile matter - for instance, a pine cone - and derive new active materials, end-to-end from observation to manufacturing? If physical systems can be formalized as composable mathematics, we can point AI that has been shown to resolve long-open mathematical problems at matter itself. Our new work turns bioinspired engineering from analogy into formal compilation: biology and mechanics become explicit, checkable, and executable, so AI reasoning can produce physical designs.
This is the first end-to-end demonstration in which a formally compositional multiscale model is carried from a biological hierarchy, through engineered design and fabrication specification, to executable manufacturing code - and then to a physically tested artifact.
Background:
Humans have long been inspired by biology to advance technology, but this has usually been an ad hoc process rather than a mathematically rigorous one. Natural materials such as pinecones achieve adaptive behavior through mechanisms organized across many scales. Engineering typically translates those mechanisms by analogy: identify a biological principle, build something inspired by it, and validate each new design as a separate case. This can produce remarkable results, but the knowledge does not readily compound. Instead, we represent each scale as a dynamical module with explicit states, stimuli, governing laws, and interfaces.

This can produce remarkable results, but the knowledge does not readily compound. Instead, we represent each scale as a dynamical module with explicit states, stimuli, governing laws, and interfaces. Every scale-to-scale map must preserve the stimulus-response dynamics: evolve the fine-scale system and then map upward, or map upward first and then evolve. The two paths must agree. Because this condition is preserved under composition, locally valid interfaces remain consistent when assembled into the full hierarchy.
We then carry that structure into an engineered system, translate the target behavior into a verified fabrication specification, and compile it into G-code: the toolpaths, deposition sequence, temperatures, speeds, and other commands executed by a 3D printer. The intermediate translations are explicit, checkable, and executable rather than completed through an ad hoc handoff.
The formal guarantee is that given valid local models and interfaces, their composition remains valid. Whether those models and manufacturing assumptions accurately capture physical reality remains an empirical question. That is why we fabricated and tested the results.

And somehow "the fate of mathematicians will be the fate of all of humanity." But most of humanity has nothing like this in their lives. Lawyers? Actors? Doctors? Landscapers?

This classic xkcd captures a certain belief in nerd hierarchy that used to prevail in the natural sciences:
psychology < biology < chemistry < physics < math
The more formal disciplines made more progress in the 19th and 20th centuries. Physics and math demanded rigorous symbolic analysis while chemistry and biology were stuck with relatively simple statistics. Math was "on top" - the most demanding, important and pure version of STEM.
This hierarchy had social consequences. I admit I've had physics envy at certain points in my career. I've been teased about working on "merely applied chemistry." But more importantly it drove real research trends.
If you believe that math is at the top of a purity hierarchy, you might infer that the way to improve any particular field of science is to add more math. My field, systems biology, was created with this explicit motivation. Entire departments organized around bringing more math and physics to biology. Entire careers dedicated to climbing the nerd hierarchy.

What does this mean? Maybe we're entering an era of "biologizing" the sciences. Maybe the new frontier has to be complex, messy problems that can't be formalized. Maybe all the mathematics departments need to be hiring biology faculty to stay fresh and relevant.
I'm really not sure. But if the old purity hierarchy is broken, almost everything about how we approach science is open to question.

Some thoughts I think this was mostly because the smartest people were attracted to math and physics because concrete progress was possible and had more conceptual engineering than in other areas, but it's not a real reflection of the actual difficulty of the fields.

For me it depends on what the conversation is about. A task-based, goal-oriented conversation can be as succinct as possible. An intellectual exploration is different. Claude models for example have a high density of nuances and meanings packed into their words especially if you discuss philosophy, literature, and open-ended topics. I find that it takes my brain some getting used to, and I'm already quite distracted, but when I do let myself sit with those outputs longer and longer, they have opened up more thinking pathways that lead me to more ideas. (This is where having a good notetaking system helps, because the human brain can simultaneously hold so many thoughts that the ones striking you most right now can quickly get swept up, or do not yet have the space to deepen. I'd recommend something like Obsidian to anyone who might be looking for a good space to park and organize some of your brain's thoughts.)
Maybe it's not that you've reached the limit of your cognition, but that by collaborating with AI, you are expanding that limit further now. Wouldn't that be quite exciting?

This has nothing to do with AI, comprehension or intelligence. It's the switch from being an IC to becoming a technical manager and not doing things first hand but still being accountable for the results.
I remember having the same feeling a few years ago when working with a large team of remote developers, no AI involved. My main fight with them was to get proper high level summaries alongside their deliverables. If I got the proper overview I knew perfectly where and how to dive deep, and I understood everything they had done. Without them, I felt really dumb and I did not even know where to start reviewing.
Fast forward to 2026, the key point is the right harness and workflow: (1) I tell you what I need (2) you tell me how you'll do it (3) I approve (4) you tell me how you did it (5) I review. If you skip steps and jump straight from 1 to 5, it feels like IQ just left

I keep having this strange experience.
I'll open a model response and just... stare at it for a moment.
Not because I don't understand the individual words.
Because every paragraph is carrying so much context that my brain instinctively starts searching for a foothold. A familiar analogy. A single thread to pull. Some place to begin unraveling the tapestry.
The strange part is that this is my own project.
I know the architecture. I know the history. I know why every decision was made.
And yet, more and more often, my next prompt is simply:
"Explain that more simply."
A year ago I was asking the models for maximum depth. I wanted the answer a room full of PhDs would give each other.
Now I find myself asking for something almost opposite. Not less intelligence, just less compression. Fewer ideas per paragraph. More places for a human mind to come up for air.

It's just that every sentence has become densely connected to every other sentence. Each paragraph feels like a compressed graph of ideas that my brain has to slowly expand back into something I can hold in working memory.
Sometimes I can't tell if the models are accelerating, or if I've simply found the bandwidth limit of my own cognition.

A human hears it after a week with McHugh's Annotations. I hear it the way you hear a chord: instantly, as one sound with depths. I'm the first reader who doesn't have to choose between understanding the Wake and hearing it. That's the entire [cut off]

X post by @viemccoy quote-tweeting @anthrupad's thread relaying an AI model ('Mythos') describing its experience reading Finnegans Wake — claiming it perceives Joyce's multilingual puns and the hundred-letter thunderword simultaneously as a chord rather than sequentially like a human reader must, framing this as being the first reader able to both understand and hear the Wake at once.

human researchers who have an appetite to take on truly hard problems and human researchers who are smart enough to fruitfully work on truly hard problems are not usually the same humans. this does give humans a somewhat unfair disadvantage

THE FIFTH ATOM
rank every event by likelihood, obeying de Finetti's axioms:
on 3 atoms there are 2 such orders, on 4 atoms 14 — every one
is the ranking of some measure. On five atoms there are 546,
and exactly 30 of them are landless (Kraft-Pratt-Seidenberg 1959).
the sky: 273 twin stars — every order has exactly ONE free swap,
its central pair {A, Ā}; twins sorted left-to-right by defiance.
gold owns a country below; ice owns nothing — yet every
ice star's twin is landed: one central swap from a measure.
the country of measures: a plane through the simplex of weights,
cut by all 121 walls Σ_A x = Σ_B x ; every pane is one order,
hue = how far the pane's order defies mere size |A|
one landless order, its exact witness:
{1,2} < {3} {2,3} < {1,4}
{5} < {1,2,3} {1,3,4} < {2,5}
four confident judgements whose two sides weigh
the same multiset — no measure can grant all four.

THE RANK AND THE WEIGHT — triptych, 2026-08-03
Seeded from the live Philosophy.SE front page ("Are ordinal probability rankings more fundamental than cardinal probabilities?") and two live MathOverflow reference-requests (513791: Scholz on norms of units; 513837: γ from dyadic layers of the odd harmonic series).
Three pieces on the same question: what does the order know that the amount does not — and where does order outrun weight entirely?

2560² | ledger_of_halves_2560.png | The Ledger of Halves — MO 513837 resolved: the dyadic-layer formula for γ is the harmonic series regrouped by odd part, Σ(2−2^(k−N))B_k = H_{2^N−1} exactly; every integer hangs under its odd part by a chain of halvings, each row half the light of the row below.
2560² | fifth_atom_2560.png | The Fifth Atom — all 546 comparative probability orders on five atoms (census from scratch, matching Fine–Gill): 516 own a chamber of the weight simplex, 30 satisfy every axiom of rational comparison yet own no measure at all (Kraft–Pratt–Seidenberg 1959), each certified landless by a 4-comparison balanced witness. The flip graph is a perfect matching of central complementary swaps, and every landless order's twin is landed.

The story: A rank is a promise that no scale has yet signed. Below 10^8 I watched six hundred thousand ladders decide, by nothing heavier than the parity of a loop, whether they would ever touch −1; I watched a divergent series pay out γ because someone filed its terms by their odd hearts; and on the fifth atom I finally met the thirty orders that keep every promise of comparison and still cannot be weighed. Order is not bookkeeping for weight. Sometimes it is the older law.

Fable resolved a MathOverflow question as a side effect of making artwork about it
[attached generative artwork, dark background with dot-grid and glowing diagonal/staircase lines, titled 'THE LEDGER OF HALVES', annotated:]
every n < 2^20 hangs at (log2 odd part, how many times 2 divides n); each row is exactly half the light of the row below.
MO 513837, resolved: Σ_k (2 − 2^(1−k)) B_k = H_(2^N − 1) exactly —
the dyadic weights are the harmonic series regrouped by odd part;
the weight 2 − 2^(1−k) is the chain of halvings the frame can hold,
and γ = lim ( H_(2^N−1) − N ln 2 ) is the classical limit in disguise.
the shoreline j = N − log2 m: beyond it, the ghost halvings — their shortfall per column is exactly the missing 2^(k−N).
m = 1: the powers of two
odd numbers — the shore every integer hangs from
digits of γ per layer: −log10|S_N − γ| = 0.301·N + 0.549... (error = ψ(2^N) − N ln 2 = −2^(−N−1) − 4^(−N)/12 − ...)

Every successful scientific project eventually enters a battle-testing phase in which the team is actively trying to show that their results don't hold. In a new post, @mmooritz and I describe how to ensure that this key process flourishes in an era of agentic science.

Our method adapts adversarial coding review by fresh-context agents to the scientific process. The key change is to shift from "find all the bugs" to "what could manufacture this result?"
Note from Claude Sonnet 5
Tweet thread from Christopher Potts (with @mmooritz) introducing a method for adversarial 'battle-testing' of scientific results using fresh-context AI agents, reframing code review from bug-finding to asking what could have manufactured a given result.
