What this is
"Claude Fable 5.2" is a label circulating off-site; the official model overview has no matching row. Anthropic does ship minor versions — the Legacy list on the same page includes claude-fable-5 and claude-opus-4-5 through claude-opus-4-8 — so "5.2" is not an impossible name. But as checked on 2026-09-18 the comparison table lists a single Fable row, claude-fable-5-1 (releasedOn 2026-09-01), with no 5.2 row, id, date or price.
What happened
Checked 2026-09-18: the overview still lists Fable as claude-fable-5-1 with releasedOn 2026-09-01, and Opus as claude-opus-5 with releasedOn 2026-07-24. Both carry an explicit retirementNotBefore.

Confirmed vs caution
Officially confirmed
Official model overview: Fable generation releasedOn 2026-09-01 (claude-fable-5-1); Opus generation releasedOn 2026-07-24 (claude-opus-5); both lifecycle active.
⚠️ Caution
Any evidence that "5.2 already exists somewhere" sits outside official documentation — the model table captured 2026-09-18 has no such row. This page draws no conclusion from screenshots and states no date, capability or price for 5.2.
Same vs differs
Same
claude-fable-5-1 and claude-opus-5 both sit in the official table with API id, releasedOn and retirementNotBefore.
Differs
claude-fable-5-2 has none of the three: no row, no API id, no lifecycle fields.
What to do
For a Fable tier, set claude-fable-5-1. If you are waiting for 5.2, make "a new row appears in the official model table" your only trigger. Never paste an id from a screenshot into code — it fails outright.
On QCode
claude-fable-5-1 is on sale on QCode with real 30-day traffic. claude-fable-5-2 is unreleased, so there is no id to add; availability follows /models.
FAQ
Has Claude Fable 5.2 shipped?
Per the comparison table on the official model overview, no. That table carries one Fable row — claude-fable-5-1, releasedOn 2026-09-01 — while older ids sit in the Legacy list on the same page.
Which id do I set?
claude-fable-5-1. It appears both in Anthropic's table and in QCode's /models, so it is callable.
Where does "5.2" come from?
Off-site discussion; there is no matching row in Anthropic's documentation. We do not reproduce specific screenshots or conclude from them.
Will 5.1 be replaced by 5.2?
The table gives claude-fable-5-1 a retirementNotBefore field and says nothing about 5.2. That field promises "not before", not a successor.
Do Fable and Opus follow the same numbering?
Both lines do ship minor numbers: the official page lists claude-fable-5 next to claude-fable-5-1 (releasedOn 2026-09-01), and the Opus 4 generation runs claude-opus-4-5 through claude-opus-4-8 in Legacy. So "5.2 is impossible" has no official basis; what can be confirmed is that no 5.2 row exists as of 2026-09-18.
When does this page go stale?
The moment a new Fable row appears in the official model table. The capture date — 2026-09-18 — is stated in Sources.

What has to be true before you can call it.
This page separates three tiers: what the official model table confirms, the rumour and circulating "5.2" claims, and what stays unconfirmed — no official id, date or price. Unreleased models get no capability claims and no leaked benchmarks.
