Some models can be used past your plan's limit only by paying with usage credits. When you reach that point, Claude Code now asks you what to do, with a message such as "You've reached your Fable limit for this week. Switch models?" You can choose:
- Switch to a default model.
- "Continue with usage credits".
- "Not now".
If you decline and no other model is allowed, the turn fails with an error. Setting the CLAUDE_CODE_NO_MODEL_FALLBACK environment variable turns off switching models, so the swap is blocked.
The same question can also be asked remotely, for example over Remote Control, which lets you run a session from another device. That remote question sits behind a server-controlled switch whose built-in default is on.
Reaching a credits-only model now gives you an explicit choice instead of a silent outcome, and you can answer it even when you are away from the terminal.
tengu_jazzy_corbato On for this account, and not off by defaultThe 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.

Read once, for one account on one subscription tier, against v2.1.323. It isn't a statement about your account. What a flag value here can and cannot tell you
