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.

Artifacts now default on for consumer OAuth logins

Artifacts Notable

Artifacts are now on by default for consumer OAuth logins instead of off.

Feature flag
tengu_cobalt_plinth On for this account, and not off by default

The flag server returned on for the one account this site reads, and nothing in this release compiles it off by default. The compiled default is shown below, and says which it is when we cannot read one: a fifth of gates compile in a string or a number rather than on or off, and most published releases have no gate table behind them at all. No client can see what the server returns for your account.

This account: on · anonymous baseline: on · compiled default in v2.1.234: not a boolean we can read

Read once, for one account on one subscription tier, against v2.1.234. It isn't a statement about your account. What a flag value here can and cannot tell you

What

The artifact feature no longer defaults to off. With no remote-config value present, artifacts are enabled when the account's auth source is unset, prosumer_oauth, or no_auth, and stay off for every other auth shape. Remote config can still turn it on or off in either direction.

Details
  • The gate is tengu_cobalt_plinth; only its fallback changed, from a hard false to the auth-source test.
  • Enterprise and API-key style logins keep the old off-by-default behaviour unless remote config says otherwise.
Evidence

tengu_cobalt_plinth

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