@_WEEXIAO @Osmosis_AI Congrats on the launch!!

[Kasey Zhang @_WEEXIAO]

We've raised $7M to help companies build AI agents that actually learn and work.

@Osmosis_AI is a platform for companies to fine-tune models that outperform foundation models with reinforcement learning.

Better, faster, and cheaper.

From the first minute you meet him, it’s clear how much experience Kulveer brings as a former founder. He’s thoughtful, gives super practical advice, and focuses on what actually matters, the kind of stuff that only comes from real experience.

Congrats Kulveer

@_WEEXIAO Doing god’s work

[Kasey Zhang @_WEEXIAO]

It’s easy to fine-tune small models w/ RL to outperform foundation models on vertical tasks.

We’re open sourcing Osmosis-Apply-1.7B: a small model that merges code (similar to Cursor’s instant apply) better than foundation models.
