DGX Spark, 128GB: is anything actually worth switching to from Qwen3.5-122B-A10B?

The weights fitting is the easy half.

That 128GB is unified, the OS, the CPU side of whatever you are running, the runtime and the KV cache all live in the same pool. Load 88GB of weights and you have maybe 30-something gigabytes for everything else, and a model advertising a million-token context will happily eat all of it the first time you paste a large file in.

So "it fits" is true at load time and false about ninety seconds into a real session. Check headroom at your working context, not at idle.

What actually stops the 2am "the site is broken" calls after a client handoff?

Clients do not log into a second tool for you. Ever. They log in once during the handover call, agree that it is very nice, and never return.

Anything you need read has to arrive where they already live: an email with a PDF attached, or something printed that ends up in a drawer near the desk. The wiki is for you and for whoever maintains the thing after you. Building it is fine. Relying on the client to open it is how you end up back on this thread in a year.

What actually stops the 2am "the site is broken" calls after a client handoff?

Half of this is a contract problem wearing a documentation hat.

Define the support window, the response times, and what counts as an emergency, in writing, at signature. Not after launch, when you are negotiating from a position of guilt and they have already formed the habit of ringing you.

The reason 2am calls happen is that 2am calls are free. Documentation reduces how often somebody needs you. Only the agreement changes when they feel entitled to reach you.

Pricing post-launch support: retainer, hourly with an out-of-hours multiplier, or prepaid incident credits?

Hourly with an out-of-hours multiplier is the only one of the three that changes client behaviour, and behaviour is your actual problem.

When 2am costs triple, an astonishing number of 2am problems turn out to be 9am problems. A retainer teaches the opposite lesson: contacting you is free and already paid for, so why wait.

The cost is that hourly is harder to sign and gives you lumpy revenue. Worth it early, less so once you have enough clients that predictability matters more than teaching each one manners.

Hourly or fixed price when the client cannot describe what they want

Yes: sell them a paid discovery phase first, as its own small fixed price piece. Two weeks, maybe 800 of the 5k, output is a written direction with wireframes or a moodboard and a defined scope. Then quote the build against that document. You get paid for the part that is currently free and unbounded, they get a decision they can see before committing, and if it turns out you cannot work together you both find that out for 800 rather than 5000. It has never been refused when I frame it as reducing their risk rather than mine.
