關於 Claude Fable 5.1 及透過 TokenHub 使用此模型的常見問題。
Claude Fable 5.1 是 Anthropic 目前面向高難度推理與長時程代理工作的旗艦模型。它接受文字和圖片輸入,並產生文字輸出。
它適合長時間執行的代理程式設計、多步驟研究,以及複雜的文件、試算表和簡報工作。
它提供 100 萬 token 的上下文視窗、最多 12.8 萬個輸出 token、視覺能力、工具使用,以及透過 effort 設定控制的常時自適應思考。
Anthropic 將其相對延遲標為較慢,且每 token 價格高於 Claude Opus 5 或 Sonnet 5。自適應思考無法關閉,安全分類器也可能回傳拒絕,因此應測試延遲、成本與拒絕處理。
在 TokenHub API 請求中使用模型識別碼 claude-fable-5-1,並搭配 TokenHub 帳戶中顯示的端點與憑證。投入正式環境前,請測試請求格式與回應處理。
Anthropic 將 Claude Fable 5.1 列為使用中的模型,可透過 Claude API、Amazon Bedrock、Google Cloud、Microsoft Foundry 和 Claude Platform on AWS 使用。公布的 Claude API 價格為每百萬輸入 token 10 美元、每百萬輸出 token 50 美元、每百萬快取讀取 token 0.25 美元;TokenHub 的計費可能不同。
當高難度、長時程任務所需能力超過 Claude Opus 5 在較高 effort 下的評測表現時,可以選擇此模型。對於大多數一般工作負載,Anthropic 建議先從 Claude Opus 5 開始;高流量任務則可能更適合更快或更便宜的模型。

Cache reads with Fable 5.1 cost 75% less than Fable 5’s. This reduces the cost of the model in practice by around 25% for typical workloads, and up to 45% for highly agentic ones. https://t.co/uGjoKHcbOD

everyone's posting benchmarks. dont care. here's what I found after 3 hours with it, some of this will save you time what its good at big messy context. I dumped like 40 files in and asked "where does the money actually get calculated" and it walked back through the call chain instead of guessing from the filename. older models would pick the file called pricing.js and stop saying no. asked it to make a change and it went "you can, but this breaks the thing on line 200 that depends on it". first time a model has pushed back on me and been right long boring docs. contracts, terms of service, that 90 page pdf your accountant sent. ask it "what would you ask about if you were me" instead of "summarise this". way better output it stops. you ask a one line question you get a one line answer. sounds small. it isnt what its still bad at anything where the answer is on a webpage that changed last week. still have to tell it to go search it will still confidently do the wrong thing if your instructions were vague. its not psychic, its just less stupid writing in your voice. its better than before but if you dont give it 3 of your own examples it sounds like a very polite intern stuff worth trying today paste an error you've been ignoring for months. the one you're scared of give it a decision you're stuck on and say "argue the other side properly". its annoyingly good at this tell it "dont explain, just do it" at the top. saves a lot of scrolling the mythos thing is real, same model, fable just has safety stuff on top for dual use. if you're a normal person doing normal work you will not notice the difference what I'd skip dont use it as a search engine and dont ask it to "make this viral". it can't and neither can you anyway I've had 3 coffees and got more done than last week. back to it edit: no im not sponsored. wish I was, lads edit 2: yes its paid tier. do the maths on your hourly rate and stop asking
