Startup founder here -- we tried it, and it feels bloated (Java!), bureaucratic and overcomplicated for what it is. Something like Redis queues or even ZMQ probably suffices for 90% of use cases. Maybe in hyper-scaled applications that need to be ultraperformant (e.g., realtime trading, massive streaming platforms) is where Kafka comes into play.

Have you tried Redpanda?

As others have pointed out, this is false. Google has made their models and hardware more efficient, you can read the linked report. Most of the efficiency comes from quantization, MoE, new attention techniques, and distillation (making smaller models useable in place of bigger models)

oulipo2 · 3 days ago

sure, but the issue is if you make the model 30x more efficient, but you use it 300x more often (mostly for stuff nobody wants), it's still a net loss

Perhaps it's 33x less carbon-intensive, but if we do 200x more queries than a year ago, it's a net loss...

Since a human uses ~100W of power, the .24Watt-hours of energy for an AI prompt is about 40human-seconds [Edit: 9human-seconds] of energy.

And unlike the human who spent multiple hours writing that article, an LLM would have linked to the original study: https://services.google.com/fh/files/misc/measuring_the_envi...

[ETA] Extending on these numbers a bit, a mean human uses 1.25KW of power (Kardashev Level .7 / 8 Gigahumans) and the mean American uses ~8KW of power according to https://en.wikipedia.org/wiki/List_of_countries_by_energy_co.... So if we align AIs to be eco-friendly, they will definitely murder all humans for the sake of the planet /s

The issue is that now we're over-utilizing prompts everywhere. Every search engine query. Every keypress in an AI editor. Every new website makes queries in the back. Analyze emails. etc

So it's not just about "the one query you ask ChatGPT about what you should write your mum to say you're not coming for Thanksgiving"

It's rather that an AI query is 0.24Wh, but that we are now using thousands of those per users per days, and that we globalize it at the scale of the planet, so 7 billion users... and this becomes huge

> One major question mark is the total number of queries that Gemini gets each day, which would allow estimates of the AI tool’s total energy demand.

Yeah, I was more interested in knowing the total amount. A "median" prompt without the information on the total number of prompts is kind of meaningless...

oulipo2 · 5 days ago

also an average would make much more sense here than a median, but we can assume it's much higher and that might be why they don't communicate it?

I asked GPT 5 to extrapolate this to a Max Claude code monthly usage, two sessions a day, just business days. It guessed that would be 21k prompts a month. Google’s proxy numbers give a monthly footprint of ~5.1 kWh, ~5.53 L water, and ~0.64 kg CO₂e for heavy CC use.

That's equivalent to doing less than two miles driving(CO2), one toilet flush (water) and about three dryer loads of laundry.

Sure, but now multiply that "new use-case" that we weren't consuming before by 7 billion humans on the planet... that's the issue

We can always keep adding new stuff and say each time "oh but it's small"... sure, but if we keep adding more, altogether it becomes huge

The original press release and report are at [1], couldn't find a link to them in the article.

> In total, the median prompt—one that falls in the middle of the range of energy demand—consumes 0.24 watt-hours of electricity

If they're running on, say, two RTX 6000s for a total draw of ~600 watts, that would be a response time of 1.44 seconds. So obviously the median prompt doesn't go to some high-end thinking model users have to pay for.

It's a very low number; for comparison, an electric vehicle might consume 82kWh to travel 363 miles. So that 0.24 watt-hours of energy is equivalent to driving 5.6 feet (1.7 meters) in such an EV.

When I hear reports that AI power demand is overloading electricity infrastructure, it always makes me think: Even before the AI boom, shouldn't we have a bunch of extra capacity under construction, ready for EV driving, induction stoves and heat-pump heating?

I'm not sure why they would report on the median prompt, and not the average, which would give a better sense of (well average) consumption in this case

In China they have car battery swap stations. For such batteries, owenership does not make much sense, so a subscription model indeed seems logical. The monthly fee covers the cost it takes for the company to replace worn cells; electricity could be charged separately for cars. For scooters, since the batteries are easy to swap yourself, buying and swapping a new battery is not that big of a deal, so I don't see subscriptions working as well there as for cars.

oulipo2 · 5 days ago

(Gouach co-founder) Yes! Our battery would be perfect for a swap business, they could easily fix damaged batteries, repair cells (only $50, instead of buying a new battery at $300 retailer price), and at the end, they could even retrieve used cells to sell them back for energy storage applications!

An even bigger model for vans (to get 2 kWh) would be great. But electronics for 48V is still rare and expensive.

Would this be possible in 12V ?

Can we also put LiFePO4 instead of Li-ion ?

oulipo2 · 5 days ago

We are working on larger models already, and we plan on models for LiFePO indeed!

>> It keeps you updated on the status of cell performance and heat through a Bluetooth-connected app

why an app? Why not a simple light or error code on device?

oulipo2 · 5 days ago

There is both! But the app obviously has a few advantages in our setup:

- it gives much more detailed and fine-grained informations

- it allows user (optionally) to register for automated safety alerts

- but more importantly, it allows users to override themselves the communication protocol of the battery, to adapt it to any bike

For now we've hardcoded Bosch, Bafang, Brose and a few others (more coming), and we plan to open-source the communication protocol soon so that anyone can upload their own WASM code on the battery to talk to any controller!
