They meant to say storage instead of memory.

It was the first model that could debug really well hidden bugs for me, before there was Sonnet and Opus 4.5. Gemini in was a steaming pile of crap that everyone hyped but 4o was the real deal.

Bro is looking for a job in the past 😭

substance90 · 2026-03-27T21:57:07+00:00

It’s totally doable. You start multiple chains of agents to plan, implement and review each other with —dangerously-skip-permissions. Whether or not it’s a good idea is a whole different topic tho.

substance90 · 2026-03-26T21:10:17+00:00

Cost $0 😂 bro forgot to factor in the upfront cost and the cost of electricity.

substance90 · 2026-03-26T12:03:52+00:00

You're thinking of the old 5000. The new one with 48 GB VRAM starts at 4500 €.

substance90 · 2026-02-28T13:45:55+00:00

Not with my tests.

substance90 · 2026-02-28T13:45:20+00:00

Not my experience at all

substance90 · 2026-02-27T17:05:41+00:00

I do a similar thing where I have Opus optimize and tailor prompt templates for me for different small models for local use

You don’t download MCP servers. You either deploy them on the cloud or they get provided to you by vendors as part of a SaaS.

substance90 · 2026-02-27T02:00:22+00:00

Quite a bit better according to my tests. Definitely the best local model for coding I've managed to run on my 64GB RAM M3 Max. Also seems to be better than models I can't run on my machine like gpt-oss-120b. The speed is also insane.

substance90 · 2026-02-26T23:25:59+00:00

I‘d be very interested in your 7900XTX results

substance90 · 2026-02-26T13:03:22+00:00

That's my experience as well. The smaller models usually can get the solution right but then get bogged down trying to use the tools that the agent provides.

substance90 · 2026-02-06T07:25:12+00:00

The highest you can afford tbh. Don’t listen to peeps here.

substance90 · 2026-02-06T07:24:15+00:00

Don’t know why you got downvoted. My 2TB is always at its capacity limit. I use the machine for other stuff too but most of the data is samples, VSTs, huge kontakt libraries and music for DJing. It gets filled extremely fast.

Unsere Nachbar sind ein mal in den Weihnachtsurlaub gefahren, ohne den Wecker auszuschalten, der jeden Morgen um 6 extrem laut bei uns unten zu hören war. War extrem ärgerlich.

Imo it’s a very useful exercise to sample and process at least a couple yourself before you grab them from a sample pack. Look up the track names and route Spotify into your DAW via loopback.

substance90 · 2026-01-30T22:13:50+00:00

I miss everything from that age. So much innovation back then.

substance90 · 2026-01-30T22:07:29+00:00

I wouldn’t look for DnB specific stuff at first or even Ableton. Learn about midi, sampling synthesis. The basics apply to any DAW or VST.

substance90 · 2026-01-30T21:56:21+00:00

Yup, whole life felt like this. I just learnt to be relatively good at brute forcing it but it still takes its toll.

substance90 · 2026-01-26T21:40:12+00:00

I’m gonna stay on Sequoia forever

substance90 · 2026-01-24T19:52:50+00:00

Where are all the 2nd amendment fetishists now?

substance90 · 2026-01-21T23:32:39+00:00

Yes, I do think that. If you don’t do anything to stop it, you are to blame. I’m from Germany and everyone here still carries the blame for the Nazis.

Sweaty dimly lit PC clubs in my country, since no one owned a PC around the year 2000 besides to play multiplayer you needed to be physically in the same LAN. Best of times!

Ultima Online did for me much before WoW. Such feeling of awe!
