在眾多大型語言模型(LLM)強調「長上下文理解」能力的當下,Fiction.live 推出了業界首個真正以小說創作為核心的評測基準 —— Fiction.LiveBench。這是一個面向真實應用場景的評測,目的是協助寫作者了解哪個 AI 模型能真正「讀懂故事、角色與情感糾葛」。


✍️ 測試動機:現今 LLM 的長篇閱讀力仍嚴重不足

Fiction.live 作為協助作家撰寫大綱、時間線、角色設定等工具的網站,發現一個重大痛點:

「大多數 LLM 雖然聲稱支援超長上下文,但實際在情節追蹤、角色轉變、潛台詞理解方面仍頻頻失誤。」

因此他們發起了 Fiction.LiveBench,針對多部極其複雜的長篇小說進行改編與測試,模擬真實寫作中 LLM 所需處理的挑戰。


🧪 測試方法:比現有的 LongBench 更貼近實戰

測試並非單純考驗「搜尋能力」,而是真正測量模型能否理解:

  • 人物關係變化(如:愛恨轉折)
  • 埋下的伏筆是否被成功掌握
  • 哪些訊息是讀者知道而角色不知道(角色視角與敘事視角差異)
  • 情節邏輯與心理動機

他們設計出不同長度(從 0 token 簡化版本到 120k token 完整故事)的測試版本,評估模型在不同上下文長度的表現差異。


📈 測試重點結果

💡 關鍵發現:

  • Google Gemini 2.5 Pro 是目前唯一一款在120k token 長文測試下仍維持 90 分以上準確率的模型,堪稱首次可實際用於長篇寫作的 AI。
  • Claude 3.7 Sonnet Thinking 版 在 8k token 內理解力穩定,且邏輯一致性明顯優於 Claude 3.5。
  • DeepSeek R1 表現超越 o3-mini,是預算有限使用者的高性價比選擇。
  • GPT-4.5 PreviewGPT-4.1 雖無特殊推理設定,但在大部分 context 下表現穩定。
  • qwq-32b 表現出色,超越 DeepSeek 並穩居前段,尤其在 32k 內保持高分。
  • LLaMA-4 Maverick 與 Scout 則令人失望,表現不如 LLaMA 3.3,長文理解力嚴重不足。

🧠 為何這個測試比其他 Benchmark 更「難」?

市面上很多測試(如 LongBench、Needle-in-Haystack)偏重「搜尋正確答案」,而 Fiction.LiveBench 則關注深度理解、情感邏輯與故事整體感知。這些都是小說創作時 LLM 真正需要具備的能力。


🗒️ 結語:哪個模型才是寫小說的好幫手?

對小說創作者而言,真正可用於創作的 LLM 終於出現了 —— Gemini 2.5 Pro 領先業界,Claude、GPT-4.5、DeepSeek R1、qwq-32b 也各有亮眼表現。

He sports dark brown hair and a light beard,wearing a bright red t-shirt emblazoned with 'style' in bold white text within a blackrectangle, layered beneath an open blue and black plaid long-sleeved shirt. His attire includes grey cargo shorts, white socks, and distinctive red, white, and black high-top sneakers. In his left hand, he holds a black selfie stick, while his right grasps the paragliding control lines. The stunning backdrop features crystal-clear turquoise and deep blue ocean revealing intricate coral reefs and gentle breaking waves near a pristine white sandy beach. A charming coastal town with numerouswhite buildings is nestled against lush, emerald-green, tree-covered hills, which ascend to distant, hazy mountains under a softly clouded sky. Another yellow paraglider gracefully soars in the distance, and a long concrete pier extends into the tranquil water. The scene is illuminated by bright, diffused natural light, creating an exhilarating, free-spirited, and idyllic tropical mood, with a color palette dominated by vivid turquoises, deep blues, and verdant greens, beautifully contrastedby the crisp whites of the beach and town, and the bold reds of his clothing and footwear. {
