> As a result, Astra spots and fixes a common failure of tiny reasoning models: they loop [13]. When the base model loops, it repeats the same text and rarely reaches an answer (85 of its first 96 practice answers ran to the 32,768-token limit). Astra traced the looping to one direction written by the MLPs of layers 15 and 19, and subtracted that direction from 64 output columns in each (131,072 weights), much like removing a behavior by deleting a single direction from a model’s weights

HA! Now that's cool. Not necessarily the improvements, those are ancient and probably overtrained benchmarks, but it's so cool that the model found a singular direction for this "loop bug". I imagine it could possibly do much the same thing in finding other "single directions" on a variety of topics (if allowed by guardrails). This is really really cool, especially for the mechinterp folks.

Can't wait to see qwen4 and qwen5 as this becomes more common.

It's pretty much how abliteration works too; find where the refusals are happening and flip the bit.

That... is a good point and concerning WRT open models. We like open models as they seem to be a gift to humanity, but at the same time, they can't be reliably tamed and can always be realigned to get around guardrails. We have discovered fire and have yet to see its full destructive potential.
Re:Astra can read and write weights to improve Qwen by prophesi on Tuesday November 03, 2026 @04:55AM (#50350017)
I think we already are seeing the destructive potential :/ The genie's out of the bottle at this point with open-weight models (and thus can be abliterated in terms of offensive cybersecurity) that can run inferences well on relatively cheap hardware with relative parity to frontier models.

I'm a bit of an outlier in regards to today's HN culture. I'm still holding on to Stallman's idea that information wants to be free. There was a comment on another thread that aptly elucidated what I think is necessary.

Not everyone has the know-how or desire to compile the Linux kernel, or any what-have-you executable in user space. But a good amount of people do, and it's a boon to security/privacy that they do, and cryptography can verify that this work was done. (granted, manufacturing a computer is an international effort with a lot of unknowns, ie proprietary binary blobs in BIOS/UEFI) (and people are lax to validate the crypto themselves if it's not an automated thing; that's a UX problem imo)

I think we'll eventually find sufficiently performant LLM's trained on public domain information[0] that people can validate. Sufficiently performant training algorithms that people can validate[1]. And FOSS plugins to integrate with their FOSS IDE's which they can validate. And like the Linux kernel, volunteers to make sure there's nothing fishy going on end-to-end.

I have no horse in this race though. I'm just happy I can learn how these things work and toy around with getting quantized models to work well enough for my coding side projects. Though I often reach for a frontier model for serious coding issues, local for rubber-ducking, and Kagi's research assistant for initial planning.

[0] Pipe dream, unless international copyright law drastically changes. Since opening the dataset for any competent LLM will violate said laws, whether obtained legally or not themselves.

[1] Knowing the training algorithm and dataset will let it actually be open source models instead of open weights.

edit: These are just shower thoughts; didn't mean to write such a long response. Would love any pushback or any correspondence in general since it'll be on my mind all day.

Like altering DNA

No, not like that at all.

How is it different?
Re:Astra can read and write weights to improve Qwen by Timwi on Monday November 02, 2026 @11:44PM (#50348180)
Brains and neural nets are already quite different things and difficult to compare, but at least you can wave your hands and vaguely say that both are “thinking” by some means of “abstraction or generalization”. DNA is absolutely nothing like that. DNA is more like an encoding for a flowchart for a recipe for building a specific body.

> encoding for a flowchart

Which is exactly what a model with it's layer is.

Re:Astra can read and write weights to improve Qwen by dyauspitr on Monday November 02, 2026 @08:48PM (#50346947)
Exactly like that.

Both sound cool and "like, the future, maan" while smoking weed, otherwise nothing in common.
Re:Astra can read and write weights to improve Qwen by ashkankiani on Tuesday November 03, 2026 @12:31AM (#50348459)
why do we need to anthropomorphize everything. what it's like is altering the model weights of a computation graph, because that's what it is.
Re:Astra can read and write weights to improve Qwen by tty456 on Tuesday November 03, 2026 @02:28AM (#50349104)
It's not anthropomorphizing anything. It's comparing the act of altering weights as "instructions" as similar to altering our own building blocks.
Re:Astra can read and write weights to improve Qwen by dyauspitr on Monday November 02, 2026 @08:47PM (#50346940)
It’s reading minds…

But seriously, have we tried to run neural data through this.
