You can! There are systems designed around that. OpenAI even internally had GPT-4 using a multi-stage response system (a read-execute-print loop, they called it) while testing, to give it more power. There is also the "Reflexion" posts on this sub lately, where they have GPT-4 improve on its own writing. But, A, it's too expensive. Using a reflective system means lots of extra words, and each word costs more electricity.

And B, LLMs currently love to get sidetracked. They use the word "hallucinations" to say that the LLM just starts making things up, or acting like you asked a different question, or many other things. Adding an internal thought process dramatically increases the chances of LLMs going off the rails. There are solutions to this (usually, papers on it will describe their solutions as "grounding" the AI), but once again, they cost more money to do.

So that's why all these chatbots aren't as good as they could be. it's just not worth the electricity to them.

Very insightful! Seems like even without groundbreaking stuff, more efficient hardware will likely make the solutions you mentioned more feasible in the future.

Yeah, we're really waiting for electricity costs to fall if we want to implement things like this in reality.

Right now the roughly current rate of $0.10/(1000tokens)/minute/LLM will, per hour, cost us $6 per hour to run a single LLM. If you have some ensemble of LLMs checking each other's work and working in parallel, say 10 LLMs, that's $60/hr, or $1440/day. Yikes, I can't afford that. And that will maybe have performance and problem solving somewhere between a single LLM and one human.

Once the cost falls by a factor of 100, that's $14.40/day. Expensive, but much more reasonable.

But even with $60/h, this might already be profitable if you replace a job that has a higher hourly wage. Lawyers, e.g. At 14.4/h, you beat minimum wage. For toying around, yeah, that's a bit expensive.

Yeah for an individual it's no joke .

For a business it may be worth it, depending on the job.
