Where are you going to apply to with that resume that’s a step up from your current job though?

lots of places, actually. not everyone wants to be attached to the Silicon Valley culture, and that line alone will guarantee practically any workplace. that person is going to find out what work-life balance is :)

it's kind of hard to save a company billions in operating costs via software without it being part of Silicon Valley (culture)...

Didn't expect that. Luna pricing is crazy now. I don't think there is anything on the market that competes at this price-performance point. For our production app, OpenAI clearly is the best provider now. Their API is very reliable and has many nice features. The price-performance of the model lineup is incredible. We used open weights model via Fireworks for a long time (e.g. Kimi K2.5). Fireworks is a great provide…

OpenAI's APIs are extremely reliable for sure. I don't even remember when the last incident or downtime was.

all day yesterday, Taiwan time Sol was having significant issues.

“Overloaded”, maybe half of requests or more wouldn’t go through

Let's suppose each models was subsidized at 70%, so that we only pay 30% of the cost. They would loose much more money per token on the more powerful models. It's in their interest to encourage the use of the less expensive models. Let's say they increase Luna subsidies at 90%. They would still "save" relative to the use of the more expensive models.

> Let's suppose each models was subsidized at 70%, so that we only pay 30% of the cost. why on earth would you suppose that?

Because their leaked financials point that way.

Deepseek Flash is still much cheaper: - lower input/output token pricing - the cached token price is $0.0028/Million tokens, which is like 50-90% of tokens

DeepSeek Flash is a much worse model. Even DeepSeek Pro is much worse.

Slower/more verbose in my experience too. However, still self-hostable which is a major plus!

"Half the money I spend on advertising is wasted; the trouble is I don't know which half." -John Wanamaker This applies even more strongly to model choosing. I know for a fact that majority of my work doesn't require a very strong model, but separating the trivial and non-trivial tasks is a famously hard problem (if at all decidable).

Use a harness like OMP that lets you choose which model does which things. My main model is GLM 5.2, it handles planning and anything I dont have covered by other models. Tasks from todos and in sub agents are done by deepseek, I have different models for the git work like add/commit/push (that goes through cheap Minimax M3), and so on...

This way the expensive/strong model only handles the architecture and orchestration tasks. The cheaper models handle everything else and the strong one knows how to tell them what to do in enough detail to get good work out of them.

I don't see why it should be all that difficult. All you have to do is first find a library that implements a decent solution to the halting problem and you're off to the races.

Its funny because you can write a halting problem oracle by calling out to an LLM and have it return yes / no / not sure and get it to work reliably for almost all real code, like that is an entirely practical thing to do in 2026. All we need now is some sort of program to evaluate halting problem oracles...

Wasn't the original proof something like "a program that loops indefinitely when the oracle says it will halt, and stops immediately if an oracle says it will not stop"? The whole point was the you can construct a contradictory program that cannot be decided by any oracle by its very nature.

```python

source_code = open(__file__, 'rt').read()

response = ask_llm("will this program halt, only answer 'yes' or 'no'?\n" + source_code)

will_halt = response == 'yes'

while will_halt:

   continue
```

> Starting today, GPT‑5.6 Luna, our fastest and most affordable model, will cost 80% less, I don't have the words. I genuinely thought we were in a stage where we were plateauing and going in for 5-10% improvements over months. Seeing spikes like this makes me question about where the floor really is.

Prices have consistently gone down 90% every 18 months like clockwork for about 5 years for the same level of quality. There is no end in sight for at least another generation.

There is ZERO reason to believe models 1/10th the size of frontier are completely capped on intelligence and impossible to get smarter.

They have consistently compressed the intelligence of larger models.

You'll see it first on the small end, when they stop being able to compress intelligence, you know that will slowly bubble up and up the chain to larger and larger models.

There's no evidence we've reached that at the bottom.

Competition is a wonderful thing. $1.20 per 1M output is crazy, but let’s also not forget that OpenAI was one of the first to start increasing model prices ~10-12 months ago.

GPT-5 cost $10 (per 1M output)

They still have to pay back those hundreds of billions of investment dollars somehow.

The best thing any developer can do today is to make their app LLM/provider agnostic (or use an LLM gateway) to avoid lock-in.

In fact there's very good reason to think intelligence has much more room to be compressible - the human brain, for one.
