Same here. Not again, please... I need to use it for work. So glad I cancelled my private max subscription.

humanwritten · 1 year ago

I had issues this morning too in the desktop app, it looks like they were rolling out an update as the UI changed shortly after but wasn't great as I had some important work to deliver.

Still hanging on with my subscription but they really do need to address performance some and compensate accordingly :(

Got this issue after updating to the latest version.

On average it took 6 to 8 failures like above before it can complete 1 request. (and then repeatr)

Still hanging on with my subscription but they really do need to address performance some and compensate accordingly :(

My subscription will run out this weekend. I am trying out opencode and AWS bedrock. I find it to be really promising so far. Subjectively better I would say.

just got a notification the triage bot failed too looks like its totally down

I need to test out bedrock + some other tools to have a fallback / maybe some promising alternatives.

bedrock is much faster. You pay per token though. But you have the choice to strike a good price to performance balance. I will also try connecting it to LM Studio this weekend. I have MacBook with a decent amount of memory. I will try running it with 30B qwen 3 coder MLX and some similar models. I'll see how that goes.

I just downgraded to 5x. I will spend rest of 118 on other stuff. Can buy like 5-6 other

At least this time they do not take 4 hrs to notice. Yaaaay, progress.

Go ahead, quote me properly, though. It's quite fine work. I surprised myself :D

Relax guys, they already know and working on restoring services Im sure. Try journaling or drawing out your ideas instead until further notice. 9AM fires suck.

it's so pointless to write code when claude can write and debug it 100x faster than I can on my best day.

Did they spin up a dumb version?

I define my requirements and it just ignores most of them. Simple and comprehensive task from a clean slate with examples given, which it ignores.

Good thing they now give themselves 5 years to debug these issues. It seems like they need it.

explicitly tell claude to read the files in FULL, if you're following along you'll see it will often only read a 50-100 lines of a 800 line documentation file.
