What
Added detection for a model whose name contains "fable" (case-insensitive), with adjusted response-suffix handling when that model is active.
Details
- A new helper function identifies when the active model is "fable" by checking
H.toLowerCase().includes("fable"). - When a fable model is in use, the
[1m]model-suffix token is stripped from responses rather than appended, matching how the model reports itself to the API. - This is internal plumbing that enables correct behavior for a new model; no user-facing command or flag change is required.
Evidence
New fable detector (search for "fable"); response-suffix logic updated (the g7 model-name formatter gains a new early-return branch for fable+[1m])
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
One source agreesOne thing we can check says the same as this entry.
Anthropic's release notes agree
Fixed Fable 5 model names with a [1m] suffix not being normalized — Fable 5 includes 1M context by default, so the suffix is now stripped…
