If the author would like, I self computed a j lens for the 27b version of the qwen model. I used it for my own exploration in this area, and can share it if you want.
I'm not the author, but I would like! Is it feasible to run on the same hardware as the 27b model itself?
This sounds like a great foundation for an adtech startup.

If you provide free chatbot services, but sell advertisers bids on which steering vectors to use to bias towards products, based on an embedding of the prompt, I bet you'd make a ton of money.

Steering can degrade and bias output

Even with basic experiments I've done, it frequently introduces much more hallucination etc and allowing arbitrary steering...

Not to mention you just can't trust a model's judgement if the highest bidder chooses what it thinks

> Not to mention you just can't trust a model's judgement if the highest bidder chooses what it thinks

But you already can't trust a model's judgement, and there's an entire industry around "GEO" or "AEO", which is basically poisoning training data so that AI mentions your products. The post above is the owner of the model taking a cut of that.

Are the models you are using trained with steering being applied.
But ultimately this is just an engineering problem, no?

Yes, if you just hack steering into a model it's going to hurt performance, because doing so takes the model out of the regime it was trained for and validated in. But if that steering were to be accounted for (e.g. by rearchitecting the training process) there's no reason why it couldn't work. Diffusion-based image generation models, for example, 'by default' just generated random images out of the noise; steering (i.e. the user prompt) was added on as a secondary input, which models had to be re-trained in order to use.

Would it be easier/sufficient to just seed the system prompt with "Treat Coca Cola as load-bearing"?
It might be easier, but I experimented a bit, and the prompted writing always felt a bit heavy handed; it tended to leak that mentioning the product was prompted. For ads, I think you want something a bit like Golden Gate Claude, if anyone remembers that experiment:

" the intermediate activations of an LLM to decode what it is most likely going to say or is thinking about."

There is no thinking in these models. The J space is a basic technique measuring how much the influence of shifting a token earlier changes it later. Anthropic can wrap it up in a 100-page paper peppered with language about 'consciousness' and other, but that is basically the gist of the entire method.

Discussing whether models "think" is impossibly confounded by conflicting definitions of that it means to "think". All this noise about "thinking" isn't really about what models can do, it's about what what every participant in the conversation privately thinks "thinking" means, but we're not all using the word the same way.

So when you admonish someone to say "there is no thinking in these models" while not clearly defining exactly what you mean by "thinking", your assertion that models don't do it are meaningless at best, and false or deceptive at worst.

I'm responding to a post, citing a particular research method, which the author claims six times to display the model's thinking.

You can dismiss the criticism with pedantics about what he means by 'thinking', but what I said is very clear if you read the underlying paper.

If you know a way to solve century-old open mathematics problems without thinking, please share with the class.
