CLAUDE FABLE · PRICE, LIMITS AND ACCESS
Claude Fable 5.1 in Telegram: what it costs and how it is limited
Anthropic's Fable family is its Mythos-class line, made safe for general use. VUST runs Claude Fable 5.1 as a separately named, manually selected flagship in @vustbot — you pick it, you see it named before the run, and nothing silently answers in its place.
Direct answer
How to run Claude Fable 5.1 in VUST
Open the direct link and @vustbot confirms "VUST Fable — Claude Fable 5.1" before anything runs. Send a prompt, or wait and type later. Pro and Max run it inside their allowance; everyone else keeps the prompt and sees pass options and an explicit way back to the model you were on.
Comparison basis
Official sources
Price, context window and output limit come from Anthropic's published pricing and model documentation. VUST claims neither partnership nor universal model superiority.

Claude Fable 5.1 vs Claude Opus 5.5, inside the same product
Both are Claude flagships you can select by name in @vustbot, and the difference is price and headroom, not marketing. Anthropic publishes Claude Fable 5.1 at $10/$50 per million tokens against Claude Opus 5.5 at $4/$20 — two and a half times the cost per token. VUST gives them the same 3 runs a day on Pro, and Fable more on Max. Neither is "better" for every task: Fable is the newer Mythos-class release, Opus 5.5 costs 60% less per token, and both stay separately selectable so you can settle it on your own work instead of on a benchmark table.
What bounds the model here, and who set each bound
- 1. Price, context window and output limit are Anthropic's, published with the model.
- 2. The daily run counts and the 3,000-token reply cap are VUST product limits, set for predictable delivery in a chat.
- 3. VUST claims no partnership with Anthropic and no universal quality superiority for this model.
- 4. A model identity mismatch stops the request instead of quietly answering with something else.

Frequently asked questions
Can I use Claude Fable 5.1 in Telegram?
Yes. Open the direct link to @vustbot and it confirms "VUST Fable — Claude Fable 5.1" before running anything. It is a manual choice by name, not an automatic pick.
What does Claude Fable 5.1 cost?
Anthropic publishes $10 per million input tokens and $50 per million output tokens, with cache reads at $0.25 per million. Inside VUST you do not pay a token bill: Pro and Max include daily runs. Nothing is charged for a run that fails.
Why is the reply capped at 3,000 tokens when the model can produce 128K?
Because the product is a chat. 128K output tokens is the model's API limit; a Telegram message is 4,096 characters, so an uncapped reply would arrive as a wall of fragments and cost far more than the answer is worth. The cap keeps delivery and price predictable.
Is Claude Fable 5.1 better than Claude Opus 5.5?
It is the newer Mythos-class release and costs two and a half times as much per token. That is a fact about price, not a promise about your task. Both stay selectable by name in VUST precisely so you can compare them on your own work.
Why only 3 runs a day on Pro?
At $10/$50 per million tokens this is one of the most expensive models available, and an unlimited allowance at that price would either be withdrawn later or subsidised by everyone else. A stated daily count you can rely on beats a generous number that changes.
What happens if the model is temporarily unavailable?
The run fails visibly and nothing is charged — send it again. That is different from a plan or allowance limit, which keeps your prompt and offers a way forward. VUST does not quietly answer with a different model in either case.
