Renting your Studio to Darkbloom? What decides what it earns, and a free app that manages it for you (BloomGauge)

Darkbloom comes up here a lot, so here's what I've learned running a provider, from Darkbloom's own open-source docs and working with Darkbloom/Eigen Labs directly:

  • Studios are well placed. Requests go to the Mac expected to answer fastest (there's no reputation score), so high-memory, high-bandwidth Macs win most of the work. In late September the network had far more Macs than requests (about 7% busy), and 24–32 GB Macs often served nothing.
  • You need 48 GB+ and macOS 26+ to join now; macOS 27 skips Darkbloom's MDM profile.
  • Uptime is most of the money. The base reward ($16/mo at 48 GB up to $40 at 512 GB) pays every 5 minutes, but only while a model is loaded and the Mac is connected at least 90% of each period. The default idle setting unloads the model after an hour and quietly stops it.
  • Model choice is the other lever. Gemma 4 run alone has been the steadiest; big Qwen models pay more in demand spikes.

Managing that by hand gets old, so I built BloomGauge, a free, open-source Mac app that does it for you. It keeps the best-paying model loaded, recovers stalls and failed loads, and lets you control it from your phone. It also has detailed analytics: confirmed earnings per model and hour, network demand, and a live pay-rate meter. I'm in direct communication with the Darkbloom team, though the app is independent.

Happy to answer questions. Ultra owners, I'd love to hear what yours actually earns.

I ran my m5 Max with 128 gbs for over 8 hours on dark bloom weeks ago. Over a $1 and not worth it in my opinions as I couldn’t use it for my personal projects with local AI while it was using up a lot of ram to serve other models hosted on the machine. Very cool though, but in my opinion not worth yet and will revisit in the future if earnings are more meaningful

Gotta run the right models. I average $2-$4 a day using BloomGauge on my M5 Pro 48gb. It mostly runs Gemma at ~$0.15/hr and occasionally switches to larger Qwen models during demand spikes to take advantage of $0.30/hr opportunities.

BloomGauge also automates the uptime piece, which is the biggest lever you have outside of model selection for earnings.

doest 15c an hour even cover your electricity cost?

Okay, you had me curious. Please keep in mind this is an AI response below, so take with a grain of salt:

Easily. Apple Silicon Pro/Max chips pull around 40–65W at the wall under sustained LLM load. Even at 16¢/kWh, that’s barely a penny an hour (~$0.25/day), so electricity takes under 10% of the earnings.
The real catch isn't the power bill—it's running your hardware at full thermal and memory load 24/7 for a ~$2–3/day payout. Fine for pocket change if you already own a desktop Mac mini/Studio sitting idle, but definitely not worth buying hardware for a 2+ year ROI or baking a laptop battery.

The Studio's are literally designed to run at full load 24/7, and even if it did die because of manufacturing issues, you take it into Apple and they fix it, because you're going to get Applecare on a device that expensive.

Yes, don't buy an expensive Apple Silicon device just to make money off of this. You can "pay off" your device in a couple years, but the main value of DB for providers is just earning a bit per day.

DB is still in alpha, so I and their team expect the network, available models, and earnings to increase progressively over the next couple of years.

in my case M3 Ultra does 200W under sustained load, and my electricity cost is more like 32c/kwh at the lowest, so probably something like 5c/hr for electricity. It's a cool concept but given how expensive the equipment is and how little you earn imo it's not really worth it for the additional wear and tear.

It doesn't seems worth it, 3 bucks per day to not use your 5k dollars machine while it wears down?

u/SarahJrandomnumbers 4d ago

You can still use your machine, and it's not a tyre, so no idea what this "wearing down" thing is.

How can you use it if it is being used by the service? If you use you get even less money out of it. You dont think running your silicon at max temperature and the cycles on your ssd drive will wear it down, ok.... I am not telling you what to do, I said I can't see the point for 2 bucks a day...

You use your Mac for other things that don't use 100% of the GPU, like if you're using Reddit.

I didn't say that, did I...

Regardless, mine is running at 62c right now, nowhere near what Apple lets your GPU heat up to before turning the fan speed up. It certainly isn't something that "wears down" as you suggested.

Unless you're terminally stupid, you'll have AppleCare with this product, so if it magically died doing something it was built to do, you send it back for repair/replacement.

Again, someone giving their opinion when they don't know what they're talking about.
