If you're trying to give agents real work and control is what's stopping you, apply for early access today.

Every new account starts with $50 in free credits, enough to run an agent for a month, with no credit card needed.

Today we're announcing @runta's $20M seed, led by @a16z.
Software is constrained when you write it. Agents have to be constrained while they run.
Runta is the execution layer that controls what AI agents can actually do.

FrontierHarness v1.1 is past halfway.

21 harnesses, 5 models, 62 tasks.

Cost per pass:
1. Codex $0.57
2. Pi $0.67
…
21. Antigravity $1.32

First vs last: 2.3× cost per pass, 1.9× average cost per task.

Pass rates: 56.2% to 77.6%.

Which gap would actually make you switch harnesses, pass rate or cost?

We’re spending up to 100B tokens across 26,040 agent runs to answer one question: when you switch models, should you switch harnesses too?

Our v1.0 FrontierHarness leaderboard ranked harnesses on a single model.
V1.1 expands it to 21 harnesses × 5 models × 62 tasks × 4 attempts, 72x the size of v1.0.

Results are coming in live. Link below🧵

Guanlan Dai Verified account @guanlan Nov 4

@Runta's Singapore office is open! 🇸🇬

Six months of preparation. Skipped the cramped high-rises for a green, light-filled workspace.

Hiring for agent infra team for both SG and US:
* Infra Engineer (FaaS / container scheduling / virtualization / RL infra)
* Product Engineer (build in public, open-source, community, design sense)

DM me if you’re into agent infrastructure.
