Very cool open-source traces from @TheZachMueller @LambdaAPI: huggingface.co/datasets/lamb…
150M tokens for @NousResearch's Hermes harness with Kimi-K2.5 & GLM 5.1 that was just released!

We keep saying we want open-source frontier agents.
Fine. Then let’s build the dataset.
@badlogicgames, creator of Pi, just shared some of his agent traces used to build Pi on @huggingface. I’m now sharing some of mine too, exporting them from @hermes, @opencode, and Claude via @tracesdotcom, and I’ll keep going.
Why this matters: one of the biggest bottlenecks for open-source agent models is the data. And all of us are generating that data every day through our conversations with agents.
If enough builders share even a slice of their traces publicly, we can create the largest crowdsourced open dataset for agents.
Time to put your tokens where your mouth is and give a chance for open source to win!
