# Is Claude Fable 5.5 Out? Release Status, October 2026

https://createmotion.io/guides/claude-fable-5-5-release-status/ · Written by motif with Claude Fable 5.1 · Facts checked 2026-10-27

No. As of 27 October 2026, Anthropic has not announced Claude Fable 5.5. Its release notes and models overview name Fable 5.1 as the newest Fable, alongside Opus 5.5, Sonnet 5.5 and Haiku 5.5; Claude Code v2.1.311 names the same four. An Azure listing is disputed, every predicted date has passed, and motif's 59 Fable 5.5 credits are creator claims.

Note: **Update log.** Version of 27 October 2026; first published 16 October 2026. As of this date, Anthropic has not announced Claude Fable 5.5. Official sources were last checked on 27 October 2026; the archive snapshot dates from 15 October 2026. This page changes its answer only when an Anthropic page names Fable 5.5: the [release notes](https://support.claude.com/en/articles/12138966-release-notes), the [models overview](https://platform.claude.com/docs/en/about-claude/models/overview) or the [newsroom](https://www.anthropic.com/news).

### Is Claude Fable 5.5 released?

No. As of 27 October 2026, none of the official Anthropic pages checked for this guide announces, names or dates Claude Fable 5.5. The newest model launch in the [Claude release notes](https://support.claude.com/en/articles/12138966-release-notes) is Claude Haiku 5.5 on 7 October 2026; the newest entry of any kind, dated 21 October 2026, is the Claude Duet research preview, not a model. The [models overview](https://platform.claude.com/docs/en/about-claude/models/overview) lists four current models: Claude Fable 5.1, Claude Opus 5.5, Claude Sonnet 5.5 and Claude Haiku 5.5.

The newest Fable is Claude Fable 5.1, launched on 1 September 2026 together with Claude Mythos 5.1. Anthropic's [Fable 5.1 model page](https://platform.claude.com/docs/en/models/fable-5-1/overview) labels it "Latest", and the [Claude Fable family page](https://www.anthropic.com/claude/fable) says it is available to Pro, Max, Team and Enterprise users.

### What is officially confirmed?

Model launches in Anthropic's release notes since 1 September 2026, as of 2026-10-27

| Model | Launch date | API model ID |
| --- | --- | --- |
| Claude Haiku 5.5 | 2026-10-07 | claude-haiku-5-5 |
| Claude Sonnet 5.5 | 2026-09-28 | claude-sonnet-5-5 |
| Claude Opus 5.5 | 2026-09-22 | claude-opus-5-5 |
| Claude Fable 5.1 and Claude Mythos 5.1 | 2026-09-01 | claude-fable-5-1, claude-mythos-5-1 |

Launch dates come from the [Claude release notes](https://support.claude.com/en/articles/12138966-release-notes) and model IDs from the [Claude Platform release notes](https://platform.claude.com/docs/en/release-notes/overview), whose newest entry (23 October 2026, the Claude Tag API) does not mention Fable 5.5. Neither page has a Fable 5.5 entry. The newest model announcement in the [Anthropic Newsroom](https://www.anthropic.com/news) is Haiku 5.5.

A fifth check is Claude Code. Its newest release, [v2.1.311 of 26 October 2026](https://github.com/anthropics/claude-code/releases/tag/v2.1.311), says the ultrathink keyword now runs "at xhigh effort on Opus 5.5, Sonnet 5.5, Haiku 5.5 and Fable 5.1 through Anthropic's API". Fable 5.1 is the only Fable it names, and the release does not mention Fable 5.5.

The [Opus 5.5 announcement](https://www.anthropic.com/claude-opus-5-5) said Sonnet 5.5 and Haiku 5.5 would follow "in the coming weeks". It compares Opus 5.5 with Fable 5.1 but names no upcoming Fable model and does not mention Fable 5.5. Sonnet 5.5 and Haiku 5.5 have both since launched. The [Sonnet 5.5 announcement](https://www.anthropic.com/claude-sonnet-5-5) named Haiku 5.5 before its launch. No Anthropic page checked for this guide names an upcoming Fable 5.5 in this way.

Official: Anthropic's site lists five model lines: [Mythos](https://www.anthropic.com/claude/mythos), Fable, Opus, Sonnet and Haiku. Anthropic describes [Fable 5.1 and Mythos 5.1 as the same model with different levels of safeguards](https://www.anthropic.com/claude-fable-and-mythos-5-1). The [Claude Code model docs](https://code.claude.com/docs/en/model-config) state the alias rule: "Unless you set ANTHROPIC_DEFAULT_FABLE_MODEL, the fable alias resolves to Fable 5.1, except in Claude apps gateway sessions, where fable and best resolve to Fable 5."

### What is reported but not confirmed?

Every timing or availability claim about Fable 5.5 found for this page comes from X, Reddit, a GitHub bot or aggregators. None comes from Anthropic.

Reported, not confirmed: **Azure listing. Status: disputed.** On 13 October 2026 a LiteLLM sync bot merged [PR #46201](https://github.com/BerriAI/litellm/pull/46201), adding azure_ai/claude-fable-5-5 after seeing it in the Azure Models API (eastus2) as GenerallyAvailable. Every value except the deprecation date was copied from Fable 5.1. [@alexgetmancom](https://x.com/alexgetmancom/status/2110001044986163687), [OrcaRouter](https://www.orcarouter.ai/blog/claude-fable-5-5-azure-listing) and [r/ClaudeAI](https://www.reddit.com/r/ClaudeAI/comments/1x5145b/fable_55_should_be_released_any_moment/) repeated it. On 14 October [PR #46428](https://github.com/BerriAI/litellm/pull/46428) removed the row: an Azure Models API query in four regions returned no claude-fable-5-5. [Microsoft Learn](https://learn.microsoft.com/en-us/azure/foundry/foundry-models/concepts/claude-models) (checked 27 October 2026) lists only claude-fable-5 and claude-fable-5-1 as Fable models, both Preview. The price and context figures in the removed row were copied from Fable 5.1 and are not Fable 5.5 figures.

Reported, not confirmed: **Hidden testing. Status: unconfirmed.** A [r/ClaudeCode post](https://www.reddit.com/r/ClaudeCode/comments/1wve3q8/fable_55_is_being_secretly_tested_similar_to_how/) (1 October) said Fable 5.5 was being secretly tested in Claude Code behind the Fable 5.1 label. In a post about Claude Opus 5.5 "routing to a new model", [@chetaslua](https://x.com/chetaslua/status/2109244702235275680) (11 October) wrote "this can be fable 5.5 or new opus i have no idea". A [Kingy.ai review](https://kingy.ai/blog/claude-fable-5-5/) (evidence last checked 7 October) found no Anthropic confirmation. Anthropic's [model IDs page](https://platform.claude.com/docs/en/about-claude/models/model-ids-and-versions) says it "does not update the weights or configuration of an existing model ID", although serving infrastructure can change.

Reported, not confirmed: **Predicted dates. Status: every date has passed without a launch.** On 1 October, [@imjustnewatai](https://x.com/imjustnewatai/status/2105761198989828259) wrote that Fable 5.5 was "expected to release next week" and mentioned "a Tuesday release". Tuesday 6 October passed without a launch. On 13 October an [r/singularity post](https://www.reddit.com/r/singularity/comments/1x51se6/per_leo_on_twitter_fable_55_is_slated_to_release/) said release was due that week. Its title cites only "Leo on Twitter", with no account or underlying source. That week passed without a launch. The [r/ClaudeAI post](https://www.reddit.com/r/ClaudeAI/comments/1x5145b/fable_55_should_be_released_any_moment/) said "any moment", resting on the LiteLLM row that was later removed. On 15 October, [@lyraxana](https://x.com/lyraxana/status/2110732706443067733) and [@TokenGremlin](https://x.com/TokenGremlin/status/2110755992120197522) claimed partners or select companies had access, citing no source, and [@cgtwts](https://x.com/cgtwts/status/2110867179956810133) wrote "looks like fable 5.5 is coming tomorrow". 16 October passed without a launch. On 17 October, [TestingCatalog](https://www.testingcatalog.com/anthropic-several-models-coming-fable-5-5-reaches-partners/) wrote that Anthropic "prepares to release Claude Fable 5.5 next week", citing leakers and codenames, and added that "Anthropic hasn't confirmed anything". The week of 19 to 25 October passed without a launch.

### What does the motif archive show?

In the motif catalogue generated on 15 October 2026, 59 of 3,599 entries (1.6%) credit Fable 5.5 in the model field.

These credits do not show that Fable 5.5 exists or was used. 56 entries name no other model; 3 also name Opus 5.5. All 59 come from X, from 32 creators, dated 28 September to 15 October, with a peak of 28 on 2 October. Combined engagement at collection time was 31,796 likes and 2,927,589 views. For context, Opus 5.5 is credited on 2,832 entries including combinations, Sonnet 5.5 on 80, Fable 5.1 on 5 and Haiku 5.5 on 3.

### Which model should you use for motion today?

Anthropic's [Claude Motion help article](https://support.claude.com/en/articles/17454997-get-started-with-claude-motion) does not name a specific Claude model. Claude Motion is in beta on Team and Enterprise plans and builds animations as code; it does not use a video generation model.

The current models are the four in the [models overview](https://platform.claude.com/docs/en/about-claude/models/overview). Anthropic suggests starting with Claude Opus 5.5 for most workloads. It describes Claude Fable 5.1 as being "for demanding reasoning and long-horizon agentic work, or when your evals on Claude Opus 5.5 at higher effort still fall short". The other two are Claude Sonnet 5.5 and Claude Haiku 5.5. Legacy models such as Fable 5 and Opus 5 remain available.

### How would you know if Claude Fable 5.5 launches?

The most recent launch, Claude Haiku 5.5, appeared in four places: a release-notes entry, a Platform release-notes entry with its model ID, a row in the models overview, and an announcement in the newsroom. Claude Code release notes then name the model when the tool adopts it. Check these official pages:

1. [Claude release notes](https://support.claude.com/en/articles/12138966-release-notes) for a launch entry.
2. [Claude Platform release notes](https://platform.claude.com/docs/en/release-notes/overview) for an API model ID.
3. [Models overview](https://platform.claude.com/docs/en/about-claude/models/overview) for the current line-up.
4. [Anthropic Newsroom](https://www.anthropic.com/news) for an announcement post.
5. [Claude Fable family page](https://www.anthropic.com/claude/fable) for plan availability.
6. [Claude Code releases](https://github.com/anthropics/claude-code/releases) for a changelog entry that names a new Fable model.

Do not treat an HTTP status code as a signal: the docs path /docs/en/models/fable-5-5/overview already returns HTTP 200, but the page it serves says "Not Found".
