m_ke··on Claude Sonnet 4.6
you missed the boat on natural language being the new interface

best orgs will own their data and have full history in version control so that it's easier for LLMs and humans to work with, not walled garden traps

m_ke··on OpenClaw is dangerous
also i wasn't concerned about open chinese models till the latest iteration of agentic models.

most open claw users have no idea how easy it is to add backdoors to these models and now they're getting free reign on your computer to do anything they want.

the risks were minimal with last generation of chat models, but now that they do tool calling and long horizon execution with little to no supervision it's going to become a real problem

you should try some markdown files in git

i'm talking about ubers, airbnbs, amazons, googles and facebooks of the world, marketplace software that aggregates supply and demand

> They won't, but this is the actual reason. Nobody likes dealing with support or maintenance, and having to reach out to tiny teams is death by a million papercuts for the end user too.

you will have thousands of linear like products eating the slow moving jiras of the world. great small product driven teams, not slop thrown together by your mom

AI raises the ceiling much further than the floor and it raises the floor a ton. the best software, movies, etc will still be produced by experts in their field, they'll just be able to do way more for less.

the bottleneck at large orgs is communication already, this will get even worse when time to produce stuff goes way down. big cos will drown in slop and are probably better off starting from scratch

it's not the end of software, there will be infinitely more of it

it's the end of 80-90% margins that the valley coasted on for the last 20 years. Salesforces of the world will not lose to an LLM, they will lose to thousands of tiny teams that outship them and beat them on cost

instead of 7 figure contracts you'll have customized tailored tools for enterprises, and on the other end you'll have a custom nearly free CRM for every persona

this also means that VCs will stop investing in it, unless it's a platform with network effects and heavy lock in

m_ke··on Elevated errors across many models
Was it just me or did Opus start producing incredibly long responses before the crash. I was asking basic questions and it wouldn't stop trying to spit out full codebases worth of unrelated code. For some very simple questions about database schemas it ended up compacting twice on a 3 message conversation.
m_ke··on Django: what’s new in 6.0
What a lot of people don’t know is that SWE-bench is over 50% Django code, so all of the top labs hyper optimize to perform well on it.

Yes it would require completely new hardware and most likely ditching gradient descent for alternative optimization methods, though I'm not convinced that we'd need to turn to discrete optimization.

Before we had proper GPUs everyone said the same thing about Neural Networks.

Current model architectures are optimized to get the most out of GPUs, which is why we have transformers dominating as they're mostly large dense matrix multiplies.

There's plenty of work showing transformers improve with inner dimension size but it's not feasible to scale them up further because it blows up parameter and activation sizes (including KV caches) so people to turn to low rank ("sparse") decompositions like MLA.

Lottery ticket hypothesis shows that most of the weights in current models are redundant and that we could get away with much smaller sparse models, but currently there's no advantage to doing so because on GPUs you still end up doing dense multiplies.

Plenty of mech interp work shows that models are forced to commingle different concepts to fit them into the "low" dimensional vector space. (https://www.neelnanda.io/mechanistic-interpretability/glossa...)

yeah it's not happening anytime soon, especially with the whole economy betting trillions of dollars on brute fore scaling of transformers on manhattan sized GPU farms that will use more energy than most mid western states.

Brains do it somehow, so sparsely / locally activated architectures are probably the way to go long term, but we're decades away from that being commercially viable.

EDIT: don't have time to write it up, but here's gemini 3 with a short explanation:

To simulate the brain's efficiency using Transformer-like architectures, we would need to fundamentally alter three layers of the stack: the *mathematical representation* (moving to high dimensions), the *computational model* (moving to sparsity), and the *physical hardware* (moving to neuromorphic chips).

Here is how we could simulate a "Brain-Like Transformer" by combining High-Dimensional Computing (HDC) with Spiking Neural Networks (SNNs).

### 1\. The Representation: Hyperdimensional Computing (HDC)

Current Transformers use "dense" embeddings—e.g., a vector of 4,096 floating-point numbers (like `[0.1, -0.5, 0.03, ...]`). Every number matters. To mimic the brain, we would switch to *Hyperdimensional Vectors* (e.g., 10,000+ dimensions), but make them *binary and sparse*.

  * **Holographic Representation:** In HDC, concepts (like "cat") are stored as massive randomized vectors of 1s and 0s. Information is distributed "holographically" across the entire vector. You can cut the vector in half, and it still retains the information (just noisier), similar to how brain lesions don't always destroy specific memories.
  * **Math without Multiplication:** In this high-dimensional binary space, you don't need expensive floating-point matrix multiplication. You can use simple bitwise operations:
      * **Binding (Association):** XOR operations (`A ⊕ B`).
      * **Bundling (Superposition):** Majority rule (voting).
      * **Permutation:** Bit shifting.
  * **Simulation Benefit:** This allows a Transformer to manipulate massive "context windows" using extremely cheap binary logic gates instead of energy-hungry floating-point multipliers.
### 2\. The Architecture: "Spiking" Attention Mechanisms

Standard Attention is $O(N^2)$ because it forces every token to query every other token. A "Spiking Transformer" simulates the brain's "event-driven" nature.

  * **Dynamic Sparsity:** Instead of a dense matrix multiplication, neurons would only "fire" (send a signal) if their activation crosses a threshold. If a token's relevance score is low, it sends *zero* spikes. The hardware performs *no* work for that connection.
  * **The "Winner-Take-All" Circuit:** In the brain, inhibitory neurons suppress weak signals so only the strongest "win." A simulated Sparse Transformer would replace the Softmax function (which technically keeps all values non-zero) with a **k-Winner-Take-All** function.
      * *Result:* The attention matrix becomes 99% empty (sparse). The system only processes the top 1% of relevant connections, similar to how you ignore the feeling of your socks until you think about them.
### 3\. The Hardware: Neuromorphic Substrate

Even if you write sparse code, a standard GPU (NVIDIA H100) is bad at running it. GPUs like dense, predictable blocks of numbers. To simulate the brain efficiently, we need *Neuromorphic Hardware* (like Intel Loihi or IBM NorthPole).

  * **Address Event Representation (AER):** Instead of a "clock" ticking every nanosecond forcing all neurons to update, the hardware is asynchronous. It sits idle (consuming nanowatts) until a "spike" packet arrives at a specific address.
  * **Processing-in-Memory (PIM):** To handle the high dimensionality (e.g., 100,000-dimensional vectors), the hardware moves the logic gates *inside* the RAM arrays. This eliminates the energy cost of moving those massive vectors back and forth.
### Summary: The Hypothetical "Spiking HD-Transformer"

| Feature | Standard Transformer | Simulated "Brain-Like" Transformer | | :--- | :--- | :--- | | *Dimension* | Low (\~4k), Dense, Float32 | *Ultra-High* (\~100k), Sparse, Binary | | *Operation* | Matrix Multiplication (MACs) | *Bitwise XOR / Popcount* | | *Attention* | Global Softmax ($N^2$) | *Spiking k-Winner-Take-All* (Linear) | | *Activation* | Continuous (RELU/GELU) | *Discrete Spikes* (Fire-or-Silence) | | *Hardware* | GPU (Synchronous) | *Neuromorphic* (Asynchronous) |

We really need new hardware optimized for sparse compute. Deep Learning models would work way better with much higher dimensional sparse vectors but current hardware only excels at dense GMMs and structured sparsity.
m_ke··on Nvidia is gearing up to sell servers instead of just GPUs and components
Soon OpenAI will make its own chips and Nvidia its own foundational models
m_ke··on OpenAI is good at deals
You could say the same about the car manufacturers, lehman and every company in the valley.

The whole US economy is getting propped up by AI spending, and to continue on the scaling law ladder each new iteration requires 10x more investment. If OpenAI is not able to raise it's over for anyone adjacent to them (NVIDIA, AMD, Anthropic, etc.).

It's AGI or bust for OpenAI, because as you said there's no margin competing on API tokens since open source is almost as good for most use cases.

m_ke··on OpenAI is good at deals
Yes US can fail first and take OpenAI down with it
m_ke··on OpenAI is good at deals
Scaling Laws are the ultimate VC ponzi scheme vehicle.

Keep raising 10x more for each round of scaling and very quickly you get large enough to be able to bully anyone into playing with you.

Sama got big enough to be able to twist any arm he wants and soon OpenAI will be too large to fail.

m_ke··on The AI bubble is 17 times the size of the dot-com frenzy and four times subprime
Worse than the bubble is what's happening to the rest of the economy. If you remove AI related spending the US economy is trending in a really bad direction.

This bubble popping will definitely take down crypto with it and rip through other adjacent industries.

m_ke··on Yt-dlp: Upcoming new requirements for YouTube downloads
I wonder how Google built their empire. Who knows? I’m sure they didn’t scrape every page and piece of media on the internet and train models on it.

My point was that the large players have monopoly hold on large swaths of the internet and are using it to further advantage themselves over the competition. See Veo 3 as an example, YouTube creators didn’t upload their work to help Google train a model to compete with them but Google did it anyways, and creators didn’t have a choice because all eye balls are on YouTube.

m_ke··on Yt-dlp: Upcoming new requirements for YouTube downloads
Yeah we had to roll through a bunch of proxy servers on top of all the other tricks you mentioned to reliably download at a decent pace
m_ke··on Yt-dlp: Upcoming new requirements for YouTube downloads
I used to work on video generation models and was shocked at how hard it was to find any videos online that were not hosted on YouTube, and YouTube has made it impossibly hard to download more than a few videos at a time.
m_ke··on Trump's new visa fees spur offshoring talks, hiring turmoil
I was told that they were actually required to list them even if it’s someone transferring internally.

It was for a few specific ML research roles that I was interested in, of which there were very few in NYC and during the interview process I was told that they would go to internal candidates

m_ke··on Trump's new visa fees spur offshoring talks, hiring turmoil
When I was looking for work early this year I was told that most of the Google NYC roles were listed for internal transfers and that most of the actual hiring was in Warsaw (with 1000s of open roles, which I was told by Google recruiters at a conference in Europe)
m_ke··on Trump's new visa fees spur offshoring talks, hiring turmoil
They’re all already doing this and doing it more will go unnoticed
m_ke··on Trump to impose $100k fee for H-1B worker visas, White House says
Yeah it's even worse than that. These big cos will be incentivized to move whole teams out of the US since it will be easier to hire from other countries for offices in Paris / Zurich / Warsaw / etc.
m_ke··on How AI conquered the US economy: A visual FAQ
Exactly like the internet bubble. I've been working in Deep Learning since 2014 and am very bullish on the technology but the trillions of dollars required for the next round of scaling will not be there if GPT-5 is not on the exponential growth curve that sama has been painting for the last few years.

Just like the dot com bubble we'll need to wash out a ton of "unicorn" companies selling $1s for $0.50 before we see the long term gains.

m_ke··on How AI conquered the US economy: A visual FAQ
Could all pop today if GPT5 doesn’t benchmark hack hard on some new made up task.
m_ke··on Open models by OpenAI
No they’re usually done at each attention layer.
m_ke··on OpenAI Leaks 120B Open Model on Hugging Face
Would be interesting if this was a coding focused model optimized for Mac inference. Would be a great way to undercut Anthropic.

Pretty much give away Sonnet level coding model and have it work with GPT-5 for harder tasks / planning.

m_ke··on America Party (AMEP) FEC Form 1
Judging by the @america feed on twitter it will be all of the fascism with none of the fake MAGA populism. Good luck finding a constituency for that outside of a handful of billionaires and their groupies.
m_ke··on I used AI-powered calorie counting apps, and they were even worse than expected
I've heard from someone who knows that they're scamming people like crazy. Supposedly they also setup a bunch of LLCs to hire influencers then never paid them.
