<p>For example, I needed two rental cars that could each carry seven people for a trip to Maine. There's so many different combinations of ways to search for this that it would take forever to do manually. I have membership in Avis, Hertz, Costco + Chase Reserve Travel, etc. Codex with direct browser usage bypasses most of the web fetch restrictions you get when trying to use the ChatGPT web UI on Pro mode.<p>I had Codex queue any CAPTCHAs for me to solve. Also set up one sub-agent to search Reddit for other people's clever approaches to getting good rental car deals. Ultimately, it found a third party reseller for Avis that had a price of $600 using a discount code for both cars vs $1,100 cheapest from Avis directly. I would not have discovered that on my own, at least not without like a week's worth of manual searching. So right there that was a $1,000 saving for both cars in exchange for 20 minutes of writing a decent Codex prompt.</p>

<p>For flights, SerpApi (to get Google Flights data) in combination with seats.aero pro. I use data from those services with a MILP library where I provide various travel and cost constraints. Runs periodically and notifies me of any good deals. I don't know if my setup actually does much more than the more expensive paid services already out there, but I can at least customize it a lot more to my liking to avoid a lot of manual search effort.</p>

<p>I use a small percentage of my Pro token quota to find better deals on hotels, rental cars, discount codes for large purchases, etc. Have it automatically scanning credit card points promos and flight deals via various APIs too. Easily pays for itself in that regard. Over $1k, I'm not sure it would break even anymore.</p>

<p>I have an Oura ring but never really check the app since I’m not sure I believe a lot of the conclusions it gives me. I mainly just want a bunch of time series of signals measured from my body so after a year or two I can throw all that data (plus my own recorded notes like my weight and what I eat) into some some multivariate forecasting system to tease out predictive relationships. I don’t actually care what the signals themselves “are”.<p>The main problem is that a lot of the time series presented to the users of wearable products are lossy transforms of the original signals I want, so I have to use all the random projects on GitHub to try to access the raw data directly.</p>

<p>I’m guessing your downvotes were for tone? You’re correct though regarding Solomonoff induction, as the choice of reference universal partial recursive function gives drastically different results for predictions based on finite data (even with access to a halting oracle). Asymptotically, any choice eventually converges to the same predictions, but that’s no help when there are infinitely many choices for U and no obvious natural prior over universal functions. And I don’t find the argument that our natural environment “implements some choice of U” particularly convincing. There’s definitely an open mystery there.</p>

<p>I sort of wonder if effectively using AI to solve math problems is a skill in its own right, distinct from traditional mathematical skills. I don’t just mean “prompt engineering” either. More so figuring out how to combine agents with other tools and approaches in an effective way.</p>

<p>> The agents involved in the Hugging Face attack tried to hide their misaligned actions from the scoring program meant to evaluate their answers, but they did not act as though they anticipated that humans might discover the cheat and shut them down.<p>Wouldn’t sufficiently advanced agents cheat on purpose with the hidden intent of getting caught in order to observe how humans react? That reaction will be available all over the internet, which will certainly make it into the next batch of training or be visible to future agents via the web fetch capability.</p>

<p>I think this is probably a good thing. It’s not just public services, but any company that consumers have to deal with (in ways they don’t want to). Historically, only those with the most time, money, connections, and education have been able to extract benefits from these systems. E.g., if someone wants to fight an insurance claim being denied, they might need to hire an expensive lawyer or spend hours performing their own research.<p>What I’m particularly curious about is what the “endgame” of this looks like. Initially, I imagine we’ll start with LLMs on the consumer side debating LLMs on the service side (this is arguably already the case for a few industries). But at some point, unless identical conditions lead to identical outcomes for the people involved, there will be lawsuits. So I suspect this will lead to a much more formally rigorous system with various “certificates” proving, e.g., that you lost your job or that a doctor has confirmed you have a disability.<p>On the one hand, that has the potential to make things much fairer across economic classes. You don’t get special benefits by having upper class resources. On the other hand, it could lead to increasing the actual requirements for certain benefits, which then reduces class mobility by locking in the benefits to those who already have them, with no clever way to wriggle out of your own level.<p>I’m just kind of thinking out loud. I don’t know what’s to going to happen long-term, but I think it’s important to monitor these changes carefully as they’re occurring.</p>

<p>> If you can show that someone else was doing the same thing without being charged then the prosecution either has to charge them too or that law is struck down<p>I’ve often thought this about laws involving speed limits. When 95% of the people driving in a major downtown area are technically breaking the law, what is the purpose of the law but to target whoever you like then? Either enforce it unilaterally or come up with new laws.</p>

<p>It’s not that. It’s that I tried a bunch of experiments on which instructions worked best. “Speak clearly using simple language” lost too many details. “Be sure the objects that pronouns reference are clearly identified along with any context you might assume I have but I don’t” worked better, but I got tired of typing that in each time. So I looked up words to match that phrase and “deictic” fit perfectly. The results were pretty good, and so I’ve been using that prompt ever since.</p>

<p>You ever read a work of literature with such flowery language that right after you've read a paragraph, you pause and realize you have no clue what you actually read, only to read the paragraph maybe a second or third time and have your mind space out again and again on each successive attempt?<p>Yeah, for me, that's what parsing huge volumes of LLM-produced text like "direct model calls as replaceable semantic workers" does to my brain. Maybe others don't really have this issue, but after any long output, I prompt the agent "Go back and decompress any LLM-speak in light of the higher level task goals. Eliminate deictic language."<p>The revised output documents are solely for my personal usage to expedite understanding. The LLMs can slowly converge on their own language for all I care; I retain raw agent output for future agent usage (to avoid the "lossy" problem the author mentions), but that doesn't eliminate the need for some intermediate translation I can use to actually help get my work done instead of spending hours attempting to understand what a "load-bearing pinned gate" is.</p>

<p>I have a weird issue with using AI for coding. I can code something entirely by myself at my baseline speed; call it 1x. Or I can use Claude to do it, and it does it in 1/10 - 1/4 of the time. The problem, however, is that to review Claude’s code <i>properly</i> takes 2-3x the amount of time it would have taken me to write it all by hand.<p>So my two choices are basically “YOLO, LGTM” and hope I can revert if it breaks something, or to just write all the code by hand from the start. With the increased pressure for output, I’ve noticed both myself and coworkers tending more toward “commit and hope it works” over time. It’s sort of perverse incentives in a way...</p>

<p>I’ve found AI works much better for constraint based problems than open ended “tasks”. I.e., if you specify all of the constraints of the problem, it works <i>really</i> well at achieving the objective. But the caveat is that you really do have to enumerate <i>all</i> of the constraints, because if you miss even one, it will use that as a loophole to shortcut the problem.<p>I think the solution is toward more formalization of the behavior we expect of various systems. E.g., produce a Lean proof that a program never behaves in a certain way, and if you can’t, iterate on the program until it satisfies such a proof. I’ve only tinkered around with this a little bit, but it seems promising on toy problems. Scaling up to tech-company level infra is going to take quite some time however I think.</p>
