Each creative counted once, however many ads it runs as. Every platform publishes a different public sign an ad is working, so each row shows its own.
Every ad in our libraries is scored out of 10 by an AI model built to judge creative, up to 5 for how well it would land with a senior B2B buyer and up to 5 for craft. One of Weights & Biases's ads scored 6 or higher. We show the best in English, one per message and spread across channels, so no single campaign fills the list.

Hermes has definitely become more advantageous than OpenClaw for agent use. One of the key factors driving this is Hermes steer mode function. Allowing the agent to actually process another prompt before having to process a previous message. This is the conversational feature that is needed to keep pushing AI forward, and Hermes supports it.

Is OpenClaw cooked? OpenClaw has been powerful, but the constant maintenance is becoming impossible to ignore. For a growing number of users, reliability is starting to matter more than familiarity. So.... wat’s actually replacing it? Dev twitter has Hermes being the more reliable path forward. So they are switching. Are you sticking with OpenClaw, or have you already moved to Hermes? #hermes #openclaw #aiweights #thursdai #alexvolkov #aitools #opensourceai #aidev #machinelearning #technews #openclaw #hermes
