many people think it's about writing software but we're in the business of expectation and trust management.

this should be helpful for those who are into understanding the mechanics behind it. xitter.cf/tokenbender/status/211…

at inference level itself, we first attribute and locate the parts of network for relevant capability which is communicated via envs or dataset of choice. then we identify min standard that we want to maintain (in the case of visualisation, it is english and following tooling capability) and the peak perf which should match the base model itself. once identified, we can keep what has those capabilities at 8bit precision or lesser as needed and the remaining network can be really low bit (4/1.5) or pruned (zero). you only build the mask and ship it and can ship any number of masks for the same weights, the weights do not need to change and it can be done at inference level (even with a CPU if the task isn't too heavy).

"impossible standards" every time something like this happens i am deeply disgusted by the amount of vulgarity displayed in the name of nationalism. every such episode makes the task of anyone trying to do good a hundred times harder. you celebrate incompetence and deserve to suffer its consequences not others.
Now people should celebrate. An Indian company exits SSL/TLS business. Your witch-hunt and demand for impossible standards has worked.

Generating private keys with more than 3 digits for a world-trusted root certificate authority are not impossible standards. Badly generated keys may endanger - and have - the whole internet by breaking the most important encryption protocol. theregister.com/security/2026/… cloudflare.com/learning/ssl/w…

long back i discovered a poem that befits the current state of tech and tolerance for corruption in this place. there is no immune system kicking in, one more generation would die of this cancer. poem - "stagnant water"

We are underestimating the bad faith eMudhra possibly operated in. They actively added a step to the key generation process causing this failure but are making it seem like a dumb mistake. Let me explain with diagrams and python snippets 👇
Global TLS Intermediate CA incident: We’ve updated our incident page with how it happened, who is affected (one US customer ecosystem), what’s not affected, and what we’re putting in place. We will publish the root cause once our investigation is complete. 👉emudhra.com/en/post/certific…

eMudhra minimizes the scope by claiming only "one US customer ecosystem" is affected. In reality, 8 of its CA certificates had catastrophically weak private keys (one being simply the number 4), allowing anyone to forge trusted HTTPS certificates for any website on the internet.blog.google/security/prote…

this is insane, i cannot fathom even any 8B param model making such a mistake, this is beyond imagination. everyone involved with the eMudhra shitshow should have equivalents of perma-ban and/or investigations to this degree of neglect.

There is an (unpatchable?) supply-chain zero-day in PyTorch autograd that allows a regularization term to use the model's weights as RAM and SGD as its CPU clock to run any computation during training.

The funniest part about this is how many LoC vLLM has in comparison to DeepSeek’s inference engine lmao.

research for me has always been this and hopefully i get to do more of this. though it comes with its own caveats and it is easy to get cynical or demoralised. more so than anything else, look past all the negativity as compute and mile high clubs become everything.
Tons of bangers and useful advice for undergrads and grad students trying to make sense of how to navigate academia and entering industry in the age of agents in @Tim_Dettmers recent blog. Highly recommend people read it. timdettmers.com/2026/09/21/d…

ideas that are non-negotiable for building an ai that actually learns with experience (part 2): > agents love creating tests but they are useless and more often than not, net negative. passing these tests is like placebo. it serves no more value than giving your agent morale boost. > counterfactuals are your friend, you are looking for ways to get surprised. so in curation or synthesis, you want to explore in ways like what if agent used a differrent path than earlier. this is clear superiority over the approach where historical traces yield little value because they may only contain happy paths or select few issues. > your extraction per experience needs to be a structured and meaningful process. some of the things we use that are highly effective are - correctness, error detection/blame assignment, action-level credit, flagging possible sub-trajectories for reuse. one expensive and painful execution can support several cheap learning operations. > when is human involvement actually useful? primarily the delta i have seen in this area is where we teach the system how to construct and evaluate new experiences. correcting one answer is often weak value and thus you need to have a way to ask your human abstract questions and let the agent backtest strategies applying what it infers from those abstractions. > you want to checkpoint or version control everything. you are going to use fork/replay/diff/reset a lot if you are working on anything serious. > your evals need to be robust and diverse enough that you can identify regressions nicely. because in a continual learning environment, you are going to face random unexplained forgetfulness at times and that is why you need checkpointing, to do iterative merge and eval loops in such cases. > promotion to a new improved version should be much harder than training. think of it like how you have to use your finger multiple times to ensure it is properly being detected. useful insights gathered to make a proper update may take weeks and continual learning isn't going to look like a daily or weekly checkpoint update. > continual learning in the most practical way i look at it, is a plumbing problem.
ideas that are non-negotiable for building an ai that ACTUALLY LEARNS with experience (part 1): > collecting prod traces doesn't solve learning and logging becomes useful for learning when we can establish what went wrong. so you want a really neat mechanism to assign blame first. > majority of the agentic failures shouldn't result in training. if i was to explain this, let's say if a tool is broken, context is not handling something properly then you want to fix it. likewise if knowledge is the missing component, you need to go and fix retrieval. in an ideal world youu want to isolate for all of this and only then think about updating the weights. > one real world failure and a good human insight translates to hundreds of experiences to learn from. this is the single biggest leverage i have learnt and i would throw away all arch diagrams and fancy memory gardening in favour of this. > i love synth data and i think doing it right is art but it is equivalent to speculation. the same way a human would generate value out of a thought experiment or brainstorming while organising their thoughts on the paper. i do not expect to discover new truths by using this all by itself. > multi-agent systems work well in some cases and do not work so well in the other. is serial execution really your bottleneck? are you polluting context for a single agent too much by having decoupled tasks? then yeah, it helps. are you making them work on ideas that are not independent and they need to have lots of message passing between each other then solving message passing is your bigger value generation here. > having nine units work on something is not a guarantee of nine new solutions. error correlation is high when we are using the same model for everything and if you can, find maximum error decoupling. it is still mostly unsolved and terribly underdiscussed. > execution is your second best thing that you can do. the best thing you can do is figure out low effort or if possible barely noticeable ways to let the human annotate as much data as yo can.

i’m using the loss function from the line-go-up paper on all of 4chan and then RLing on a bunch of temu envs that last-gen claude built out of a failed startup’s monorepo it’s gonna be fine as long as we think hard enough about what alignment means

if i understand this correctly, this says modern LLMs may naturally develop specialized neurons for coherent concepts, rather than arbitrarily mixing unrelated concepts into the same neurons. so it means given sufficiently large network and enough data/compute, everything should get its clean abstraction. which is quite convenient and if it was intuitive to some people they would have started working on capabilities isolation six months ago, oh wait.
interpretability might be the most important scientific problem in the world right now, as I don't think we can solve alignment if we don't know what we're building. I think I have good news about it. I co-authored early work in mechanistic interpretability at OpenAI and came away pessimistic, because neural networks appeared to fold into arbitrary tangled knots. years later, I started openai's first large-scale automated interpretability project, finding about 2% of neurons legible with the primitive tools we had with modern agentic tools and a much closer look, the picture looks totally different. the vast majority in models up to trillions of parameters are legible, and their circuits beautiful. many famous examples of tangled neurons turned out to be misunderstood. The roadblocks I expected mostly aren't there. I now think ambitious interpretability will be solved by the time we need it most, and possibly quite soon, as automated scientists keep improving. it may be a bitter lesson for interpretability: the simple thing, at absurd scale, works already-clean.goodfire.com/

Ever wondered if you could extract capabilities and behaviors from neural networks and reuse/update/route it as needed? We introduce low-rank circuit conditioning, a novel approach that preserves the model's output behavior while reshaping how an existing capability is represented. In the base model, standard compact recovery stalls at 29%. After conditioning, the same extraction pipeline reaches 91.33% autoregressive full-answer recovery from 5.05% of MLP channels. The evidence points to a possibility of extracting and using isolated capabilities saving cost, latency and high adaptability. Read our work to understand more - tokenbender.com/posts/honey-…

fwiw, it’s an optimistic direction and i think can only be resolved as true or not with much more scaling. the more data/compute/param helping in resolving abstractions more cleanly isn’t part of the claim the blog makes and my own intuition so should clarify it first.
