A supplier slipped a PO by 8 days.

In seconds, the agent:
→ checked stock vs safety stock
→ charted the impact (we clear it)
→ drafted the supplier reply + a heads-up to planning

You review. Hit send. Done.

Suppliers sneak price increases into PO confirmations, betting no one checks the contract.

We built an agent that does.

Watch Optimized catch a 14% hike, match it to the active contract, and auto-draft the pushback 👇

@googrish really like the fact that you can chat with the model as it’s being trained

[girish @googrish]

“don’t train your own model” is common ai advice. it's wrong. your token bill's the proof.

today, we’re excited to launch castform into open preview. castform is the easiest way for you to train your own model, on your own data.

open-weights models are performant and much cheaper. when trained on your task & proprietary data, they beat closed models. the thing standing between you and that was weeks of plumbing & years of ml expertise.

with castform, model training is as simple as prompt engineering. @castformai

bring your agent traces or raw corpora. castform turns it into training data, picks the right algorithmic recipes, manages gpus, and gives you an ide to watch and chat with your model as it learns.

see what you can build with castform👇

1/ For crypto to reach its next stage of growth, it must be used less for speculation and become more like money. We believe privacy is a necessary condition for this to occur.

@nocturne_xyz we’re excited to introduce a new primitive to the Ethereum ecosystem—private accounts 🧵

How did the @wormholecrypto exploit work? I joined forces with @gf_256 and @ret2jazzy to reverse engineer the exploit, and now that it's been patched we can finally share it with you👇
