uRun

Infrastructure for the interactive era.

[uRun @urunml]

tonight. 6PM. denver. come say hi and tell us your favorite part of the CVPR so far!

if you're on the list, you've got the address. if you're not, shoot us a message and we'll sort it.

"Real-time" in marketing materials usually means "we batched it and it returns in 8 seconds."

Real-time means under 300ms. That's the threshold UI designers use to decide when to show a loading spinner.

There's a big difference. We build for the second one at @urunml.

A few seats left for our happy hour @ CVPR on thursday. come hang out and say hi.

Jun 4 @ 6:00 PM in denver. RSVP → https://t.co/AkELseZsOp

Most providers route every request to a different accelerator. Mostly fine. Until you need a stateful loop. Drift across long workflows is real. At @urunml you're pinned to the same GPU on the same machine for the whole session. Stateful by design.

heading to @MLSysConf 2026 next week in Bellevue

if you're working on inference, real-time systems, or ML infra, come say hi. always up to trade notes on what "production" actually looks like for stateful, interactive AI workloads.

[Keegan McCallum @keeganmccallum3]

Every modality in AI follows the same arc: single-shot expensive generations to multi-turn cheap interactive loops.

Text and image already went through it. Video is next.

Thank you to the early ones. 🙏 More to come. #WhatCanuRun

[Keegan McCallum @keeganmccallum3]

Two years ago, the open problem was getting an AI video model to produce a coherent 5-second clip. Recent techniques like Long Live and self-forcing solved that piece. The new bottleneck is serving it interactively. Labs are chasing the next model. The infra layer underneath is wide open.

[Keegan McCallum @keeganmccallum3]

Real-time interactive video is the hardest workload there is. Every frame has to land inside the 300ms human-perception bar. That's why we're starting there with @urunml. The rest is downhill.

Who we most want building on uRun: creative tooling companies and the studios behind tomorrow's video games. They'll go places we can't imagine → https://t.co/kbL1maA4T8

@OpenAI and @Anthropic both charge ~2.5x for "fast mode."

The most underrated pricing signal in AI right now.

some snapshots of our launch party @ Joey the Cat in SF last week.

skee-ball, open bar, and real-time AI video on every screen.

thank you to everyone who came out and pushed the demos somewhere great and weird.

Introducing the founding team with three unique angles on the same problem.

Keegan ran inference at Luma during the Dream Machine launch. Sean wrote the O'Reilly book on Docker and has our GPU orchestration dialed in. Matt was running low-latency edge inference at AWS in 2017 (back when "real-time AI" meant the cameras at Amazon Go).

We built uRun for the infrastructure bottleneck no one else is solving.

The model moat is shrinking fast.

Kimi K2.6 just beat GPT-5.4 and Claude Opus 4.6 on SWE-Bench Pro.

But the story isn't the benchmarks - it's the execution layer:

→ 300 parallel agents
→ 13 hours autonomous coding
→ 4,000+ tool calls in one run

It's no longer intelligence per token. It's tokens per second.

@faizan10114 @keeganmccallum3 Keep an eye in the coming weeks. Very exciting things on the horizon!

Imagine exploring this in real time as it generates. That is the infrastructure problem we have been solving.

[NVIDIA AI Developer @NVIDIAAIDev]

Today, we released Lyra 2.0, a framework for generating persistent, explorable 3D worlds at scale, from NVIDIA Research.

Generating large-scale, complex environments is difficult for AI models. Current models often “forget” what spaces look like and lose track of movement over time, causing objects to shift, blur, or appear inconsistent. This prevents them from creating the reliable 3D environments required for downstream simulations. Lyra 2.0 solves these issues by:

✅ Maintaining per-frame 3D geometry to retrieve past frames and establish spatial correspondences
✅ Using self-augmented training to correct its own temporal drifting.

Lyra 2.0 turns an image into a 3D world you can walk through, look back, and drop a robot into for real-time rendering, simulation, and immersive applications.
