Ryan Lopopolo: prediction

7 Apr 2026 Latent Space Extreme Harness Engineering for Token Billionaires: 1M LOC, 1B toks/day, 0% human code, 0% human review — Ryan Lopopolo, OpenAI Frontier & Symphony

“We expect that there will be some harness things there. Agents, SDK is a core [00:59:00] part of this to enable both startup builders as well as enterprise builders to have a works by default harness that is able to use all the best features of our models from the Shell tool down to the Codex Harness with file attachments and containers and all these other things that we know go into building highly reliable, complex agents.”

…so you’re just gonna be stripping specs, right? We expect that there will be some harness things there. Agents, SDK is a core [00:59:00] part of this to enable both startup builders as well as enterprise builders to have a works by default harness that is able to use all the best features of our models from the Shell tool down to the Codex Harness with file attachments and containers and all these other things that we know go into building highly reliable, complex agents. We wanna make that great and we wanna make it easy to compose these things together in ways that are safe, for example, right? Like the G-P-T-O-S-S safeguard model. For example. One thing that’s really cool about it is it ships. The ability to interface with a safety spec. Safety specs are things that are bespoke to enterprises. We owe it to these folks to figure out ways for them to instrument the agents in their enterprise to avoid exfiltration in the ways they specifically care about, to know about their internal company, code names, these sorts of things. So providing the right hooks to make the platform customizable, but also, mostly working by default for folks is the space we are trying to explore here. Yeah. And this is the snowflakes of the world just need this, right? Yes. Your Brexit of the world stripes. Yeah, it makes sense. I was gonna go back to your, I think the demo videos that you guys had was pretty illustrative. It’s like also to me an example of very large scale agent management. Yes. Like you give people a control dashboard that if you play, if you like, play any one of these like multiple agent things, you can di dig down to the individual instant and see what’s going on.…
