Pretty basic. The codex app with one conversation per project and several running simultaneously all hours. I’m going for max caching that way and it never gets lost even with compaction somehow. Each has a plan with milestones to keep up to date and a thin agents file. I check in on them in the Remote app. Use case is protocol and control reverse engineering of audio hardware. I think they must be identifying the heavy use agent sessions and cranking up their cache lives so it’s not a big deal for them.

A billion tokens a day is 11,000 tokens a second sustained. How many tokens per second are you getting off of GPT 5.6 Sol per project?

Ultra mode spins up many sub-agents. On a particularly challenging task, I’ve had as many as 29 agents working at one time.

Also if you don’t specify, most end up being the same as the parent model which is pretty wasteful.

I engineered a skill that spins up Terra High agents for most sub-agents, resorting to Sol Medium for technical research and Luna High for code/in-project research tasks.

On a slightly different topic, Luna Max is incredibly capable and doesn’t use as much quota (Luna tokens are dirt cheap).

Most importantly, are you seeing a return on investment for time and ultimate outcome?

No one can judge the enjoyment, learning, and hobby aspects. Just wondering if there is an end goal for that much overall expenditure (time, money, energy, etc.)

I absolutely see a return. I do not pay for this (we have a corporate gateway), for the price of a junior developer I can get 3-4-5 senior developer's work done. it's insane value.

Often people are counting all tokens, including cached input tokens, for those more impressive "billions of tokens" quotes.

Ah, thanks, I'd missed that nuance in the other reply!

I'd like to see a benchmark on this specific topic: Reverse engineer the hardware protocol from a driver, or just migrate a driver from one OS to another.

I agree. I’ve chipped on it with each model since 5.2 but 5.6 sol is something else. When it first came out I’d get some refusals but they’ve since stopped.

5.6 has been a huge pivotal change in reverse engineering tasks for me too (largely extracting game assets from binary client files). Something I spent literally weeks on in January with claude models at the time was solved in about 30 minutes with 5.6 Sol at medium just yesterday. It's both extremely satisfying but at the same time also a little annoying how much time I had previously spent on it only for it to be solved so quickly now. I suspect improvements in AI will continue this happy but annoyed trend.

Some people just do crazy stuff. For example this now ex yc guy who said he has agents constantly scanning Sf govt apis and forming dashboards just because

Is anyone hitting caps without agents or API usage? Seems very difficult.

Yeah I am, building large software with a vision - requirements - architecture - plan - code workflow. One Claude max account is enough to work on one, maybe two of those at a time (call it 15B tokens/month per project)
