>suspect that most the real gains are actually taking place in the harness.

Part of the reason harnesses work well is you can run a lot of agents in parallel. That doesn't slow down demand.

That is true, but the eventual realization that more machines doing more coin flips in parallel does not mean "more work gets done" might.

LLMs are amazing tech, but they're terrible without oversight. More agents faster just makes reality collapse on them quicker.

But yeah, you're right, temporarily, this will still push demand. But the topic was about "diminishing returns" as in "tech getting better". Not as in "customer spending".

It's kind of weird because more machines working together does mean more work gets done. Coin flips and weighted coin flips are totally different things. Any biases weights towards reality push you closer to reality when you use them.

New models keep being able to use more and more agents on longer time frames. Your hypothesis doesn't look like what we're measuring.

Who is we?

The people mapping AI capabilities.

Oh cool, so that we includes me! :)

Maybe turn on your light when you use a ruler? Not sure what else to say.

But high demand for LLM time isn't sufficient to keep customers at the frontier LLM SaaS providers. That demand can be satisfied locally or at non-frontier outlets, absent hardware shortages at least. The Tier 1 providers (and the would-be Tier 1s) presumably need to open up a much bigger lead in model quality, one that doesn't simply get distilled away this time, and/or continue to be protected by ongoing (or worsening!) hardware shortages. (And that's overlooking the revenue shortfalls which OpenAI and Anthropic seem to be facing already.)

I had actually been thinking more about all the non-LLM functionality that go into the harnesses. I'm not going to name names and I haven't done any rigorous testing, but my general impression is that choice of harness matters more than choice of model. In terms of basic task completion success specifically, not code aesthetics.

A perfect harness will not extract gold from a dumb model. It's a system that builds on each other, though we've not probed that frontier much to have a good intuition on what effects what.
