DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Artifact asset uploads use the streaming path

Artifacts

Artifact asset uploads now stream with stall detection instead of a fixed timeout.

What

Uploading an artifact asset now goes through the streaming upload with stall detection, replacing the fixed request timeout that previously applied to uploads.

Details
  • Applies whenever the operation is an upload; other artifact operations keep the old timeout.
  • A completion callback flags the upload as stalled when it never progressed.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
