Is Claude Fable 5.5 released?
The first-party release verified for this update is Fable 5.2, not Fable 5.5. Anthropic's November 9 announcement and Fable 5.2 model overview publish the exact API ID, pricing and specifications.
The October speculation about Fable 5.5 is not an official API contract. APIMaster has no public claude-fable-5-5 offer at the current check. Use the released claude-fable-5-2 ID when you mean Fable 5.2.
This page keeps its existing URL so readers arriving through the earlier 5.5 search term can find the current release and a route they can actually buy.
What started the Fable 5.5 rumor?
Historical October 16 report: lyra (@lyraxana) said partners had access to an upcoming Fable 5.5 and estimated a release the following week. This was a community prediction at that time, not a confirmed November schedule.
Partners got access to the upcoming Claude Fable 5.5. No info on any release date at this time but I assume next week.
Source: X post by lyra (@lyraxana).
The discussion combined earlier Fable 5.2/5.5 naming changes, requests that felt different while labeled Fable 5.1, and the separately confirmed Opus 5.5 launch. These explain why the name circulated, but do not identify the model behind an endpoint.
A product slug, internal-looking routing label, benchmark screenshot and released API are different kinds of evidence. The November 9 release confirms Fable 5.2; it does not retroactively confirm the earlier 5.5 label.
Fable 5.5 vs Fable 5.2 vs Opus 5.5
| Model | Status for this update | API ID | Official input / output per 1M | Context / max output |
|---|---|---|---|---|
| Fable 5.5 | Historical community label; no public APIMaster route | Not established here | Not quoted | Not established here |
| Fable 5.2 | Released November 9; public APIMaster routes live | claude-fable-5-2 |
$8 / $40 Standard | 1M / 128K |
| Fable 5.1 | Released older tier | claude-fable-5-1 |
$10 / $50 | 1M / 128K |
| Opus 5.5 | Released; public routes live | claude-opus-5-5 |

$2 / $10 | 1M / 128K |
Anthropic positions Fable 5.2 for demanding reasoning and long-horizon work, while recommending Opus 5.5 for most coding and knowledge tasks. Fable 5.2's vendor evaluation reports FrontierCode 2.0 High effort at 45.3%, close to Opus 5.5 Max at 45.5% for roughly half the cost per task; Fable Xhigh reaches 49.1%. These are vendor results, not our benchmark.
The practical comparison is cost per accepted result at the right effort. Do not assume a lower token price or a larger version number is always better.
What can you call today?
You can buy the released Fable 5.2 on APIMaster. The three public offers ranged from $5.2339584/$26.169792 to $8/$40 at the November 10 check. Open its model card and confirm endpoint and request limits.
For a route supporting OpenAI-compatible Chat Completions, register, create a key, and use https://apimaster.ai/v1 with the exact model ID:
curl "https://apimaster.ai/v1/chat/completions" \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"claude-fable-5-2","messages":[{"role":"user","content":"Review this migration plan and identify the highest-risk assumptions."}]}'
This is a configuration example, not a paid inference validation for this article update. Check the selected route before moving production traffic. Ordinary API availability does not by itself prove Claude Code compatibility.
Official Fable 5.2 Standard is $8/$40; Batch is $4/$20 asynchronously, and cache read is $0.20/M eligible cached input with writes, misses and output separate. APIMaster's 34.6% headline compares uncached Standard, not Batch or cache. See official pricing.
How to verify a future Fable 5.5 launch
Before adopting a later model, check first-party identity, published model ID, pricing, limits, safety documentation and the selected route's actual capabilities. A new catalog entry is useful evidence of advertised support; it is not a successful inference test.
Retain the requested ID and route metadata, test your prompts and tools, and compare latency, refusals, accepted outputs and total spend. Fingerprinting can help identify inconsistent routes, but should not be treated as an official release announcement.
For now, the Fable 5.5 status card is a future-status check. The purchasable new Fable offer is Fable 5.2.
FAQ
Is Claude Fable 5.5 available through an API?
This update verifies the Fable 5.2 release. APIMaster has no enabled public claude-fable-5-5 route at the November 10 check, but it has three for claude-fable-5-2.
What is the official Claude Fable model ID for the new release?
The November 9 release publishes claude-fable-5-2. The old community label claude-fable-5-5 is not interchangeable with that ID.
Is Claude Opus 5.5 the same as Fable 5.5?
No. Opus 5.5 is a separate released model with its own ID and pricing. Neither Opus 5.5 nor Fable 5.2 should be relabeled as Fable 5.5.
Which Claude model should I use instead?
Use Fable 5.2 for demanding Fable workloads, Opus 5.5 for most coding and knowledge work, or Sonnet 5.5 for faster lower-cost tasks. Compare the live price cards and your own evaluation results.
What is the price of the available Fable model?
Fable 5.2 official Standard is $8/$40 per million input/output tokens. APIMaster starts at $5.2339584/$26.169792, up to about 34.6% below Standard, across three public routes at the stated check. No Fable 5.5 sale price is quoted.
How do I know when Fable 5.5 is really released?
Look for a first-party announcement, official API ID, published prices and limits, safety documentation and supported public access. The earlier partner-access screenshot alone is insufficient.
