[How To Prompt @HowToPrompt__]

Google has published a paper that might end the transformer era.

For the last 7 years, every major AI, ChatGPT, Claude, Gemini, has been built on the exact same architecture: The Transformer.

But Transformers have a fatal flaw.

To remember context, they have to process every single word against every other word. It’s called quadratic complexity. As your prompt gets longer, the compute cost explodes.

The alternative is the old-school RNN (Recurrent Neural Network). RNNs are incredibly cheap and fast, but they have a fixed memory size. If you give them a long document, they get amnesia.

Until today.

Google researchers published Memory Caching: RNNs with Growing Memory.

And it fixes the biggest bottleneck in AI.

Instead of an RNN having a fixed, rigid memory that constantly overwrites itself, Google gave it a "save" button.

The technique allows the RNN to cache checkpoints of its hidden states as it reads.

The memory capacity of the RNN can now dynamically grow as the sequence gets longer.

They built four different variants, including sparse selective mechanisms where the AI actively chooses exactly which checkpoints matter most.

The results rewrite the rules of efficiency.

On long-context understanding and recall-intensive tasks, these new Memory-Cached RNNs closed the gap with Transformers.

They achieved competitive accuracy without the explosive, quadratic compute cost. It perfectly bridges the gap between the cheap efficiency of an RNN and the massive capability of a Transformer.

We have spent billions scaling Transformers because we thought they were the only way an AI could remember a long conversation.

But Google just proved we don't need to process the whole history every single time.

We just needed a smarter cache.

@JuanEgana @os_meneses The problem with the big negative output gap estimated by Banxico is that it implicitely states that potential GDP in Mexico is around 3%, which is very debatable... at least.

Politico is correct, Trump's anger at Powell has been ratcheted up, and no, he is not going to fire him.

So, what should/will they do? I'm copying what I posted here two days ago.

*Bessent: Eyeing Sometime in Fall for Discussing Next Fed Chair

Powell's term ends in May 2026. Trump will not reappoint him (that is clear).

Will Trump fire him? This is very messy (and unknown legally).

The alternative, proposed last year by Scott Bessent, was to create a "shadow Fed Chairman."

That is, appoint Powell's replacement months earlier. Then, let the nominee regularly go on financial TV (BB, CNBC, FBN, etc.) and "armchair QB" and critique every Powell speech and decision, thereby undermining his authority. Should we listen to the guy leaving next May (Powell) or the person who will be Fed Chair next May?
Sounds like the Shadow Fed Chair is coming this fall.
