As a payments processor, Stripe has conversion data. They can route based on ROI with end-to-end A/B testing or online optimization. There's a tricky credit assignment / multi-touch attribution problem to solve for some use cases, too, that could benefit from transfer learning across their customers. Also, the (unstructured) data they collect from OpenRouter users can be used to improve many other dimensions of their business, including fraud detection. Lastly, both businesses look fairly similar in unit economics if you squint hard enough; for example, they both collect a ~3-5% transaction fee from most customers.

My side project this quarter has been building a system that adds steering / planning to LLMs/WAMs/etc. (T, DiT, etc.) in a market/physics/other-ground-truth-constraints aware way. I have a small model outperforming some of the largest frontier models in some games (i.e., adversarial settings) now, but that is not very impressive because "plain old LLMs" are the wrong mathematical object for gameplay, IMO. So far, it's a mix of RL + optimization (e.g., MILP) on the planning side, and not quite realtime enough to play RTSes, but that's only a few weeks away. Have been very impressed at how far the open source ecosystem for this stuff has gotten since the last time I tried something like this.

I want to buy one of these just to support projects like it.

Why invent conspiracy theories? Occam's razor: They are leaving for companies that have filed for upcoming IPOs, so it could just as well be compensation.

This bill would likely cause game studios to release games exclusively via subscription plans as an unintended consequence.

The title does not match the article title: “We Upgraded to a Frontier Model and Our Costs Went Down”.

I would buy it. I have built a similar contraption. Let's connect.

Using the network byte ordering (big endian) of UBNT as the magic number in the protocol is a nice touch.

There is an old but still reasonable solution with mkinitcpio hooks encrypt/sd-encrypt + ssh, which is very easy to set up with EFI or grub2 onward. Tailscale is probably overkill for this use case, given that you're already exposing pre-/early- boot to the network by setting up interfaces that early. This became much more hermetic with secureboot and TPMs, too.

This is a remarkably small number given that Gentoo Portage is load bearing infrastructure under ChromeOS.
