Anthropic 推出 Claude Haiku 5.5:百萬上下文小型模型,每百萬輸入 Token 僅 0.10 美元
Anthropic has released Claude Haiku 5.5, its cheapest and fastest small model to date.It targets high-volume work like summaries, compaction, classification and subagent tasks.It keeps a 1M token context window and up to 128K output tokens.Pricing starts at $0.10 per million input tokens and $0.
50 per million output tokens.That is 90% below Claude Haiku 4.5 for prompts up to 100K tokens.Is it deployable?Yes, as a hosted API.Haiku 5.5 is generally available on the Claude API, Amazon Bedrock, Google Cloud, Microsoft Foundry and Claude Platform on AWS.What Anthropic Shipped Haiku 5.
5 is the first Haiku-class model with an adjustable effort setting.Adaptive thinking is on by default, and the effort parameter defaults to medium.It takes text and images, outputs text, and has a June 2026 knowledge cutoff.Batch jobs support up to 300K output tokens in beta.
It is important to note two key things.Non-default temperature, topp or topk values return a 400 error.The new tokenizer also counts the same text as roughly 30% more tokens than Haiku 4.5.The migration guide covers both.Pricing: A 2-Tier Structure Pricing splits at 100K prompt tokens.
Up to 100K, input costs $0.10 and output $0.50 per million.Cache reads cost $0.01 and 5-minute cache writes $0.125.Above 100K, rates rise to $0.50 input and $2.50 output.Haiku 4.5 charged $1 input and $5 output.Anthropic says about 90% of Haiku 4.5 requests stayed under 100K tokens.
After adjusting for the tokenizer, it estimates Haiku 5.5 runs about 75% cheaper on average.Batch processing takes another 50% off.GPT-6 Luna lists identical short-context rates.Its higher tier starts only above 272K input tokens, at $0.20 and $0.75.
For a 150K-token prompt, Luna is cheaper on list price.Benchmarks All figures below are Anthropic-reported (see the system card): OSWorld 2.1 (offline subset): 72.4%, versus 48.9% for GPT-6 Luna and 15.7% for Haiku 4.5.Terminal-Bench 4.0: 39.2%, versus 16.4% for Luna and 0.0% for Haiku 4.5.
FrontierCode 1.1 (Main): 46.4%, versus 42.4% for Luna.Humanity’s Last Exam: 45.9% without tools and 57.4% with tools.GDPval-AA v2.1: 1620, versus 1437 for Luna and 735 for Haiku 4.5.Sonnet 5.5 still leads every row, including 70.6% on Terminal-Bench 4.0.Anthropic itself recommends Sonnet 5.
5 and Opus 5.5 for complex agentic coding.Best Use Cases Three workloads fit Haiku 5.5 best: The first is subagent work under Opus 5.5 or Sonnet 5.5.At Rogo, a Haiku 5.5 subagent pulls a 10-K revenue line while a bigger model builds the deck.The second is high-volume document Q&A and summarization.

下一概念建模把文本生成提速最高31倍
斯坦福等聯合提出全新文本生成範式 NCM,生成速度狂飆 31 倍AIbase基地發佈於AI新聞資訊 · 1 分鐘閱讀 · Oct 16, 202633人工智能領域的文本生成技術迎來顛覆性創新。斯坦福大學與 Together AI 的研究人員近日聯手推出了一種截然不同於傳統自迴歸和擴散模型的全新文本生成範式——Next-Concept Modeling(簡稱 NCM,即“下一概念建模”)。該方法巧妙借鑑了圖像生成領域中“下一尺度預測”的思路,有望為未來的文本生成技術開闢全新的發展路線。在技術實現路徑上,NCM 模擬了人類“先構思宏觀大綱、再動筆填充細節”的寫作邏輯。整個系統通過兩階段訓練來完成:首先訓練多尺度殘差 VQ-VAE,從而得到能夠逐層補充信息的多層離散文本編碼;隨後凍結該系統,訓練 Transformer 模塊去預測下一層的編碼。在生成文本時,模型會先並行生成概念層面的宏觀大綱,接著逐層並行填充具體細節,最終組合成完整的文本內容。在實際測試表現中,NCM 交出了令人矚目的成績單。實驗數據顯示,在保持相近甚至更優生成質量的前提下,NCM 相對傳統的擴散語言模型實現了10到31倍的生成速度飛躍,並且在訓練過程中所需消耗的 token 數量也大幅減少。此外,在數獨等複雜推理任務上,它的表現也明顯優於傳統的自迴歸和擴散基線模型,同時還支持通過多生成候選挑選機制來進一步優化最終輸出效果。儘管目前該研究所使用的模型參數規模依然相對有限,其在擴大模型規模後的表現、精確文本以及長篇內容的生成能力仍有待後續驗證,但這一創新思路無疑打破了長期以來的技術慣性,為人工智能高效生成文本提供了充滿想象力的全新解法。本文來自AIbase日報掃碼查看歡迎來到【AI日報】欄目!這裡是你每天探索人工智能世界的指南,每天我們為你呈現AI領域的熱點內容,聚焦開發者,助你洞悉技術趨勢、瞭解創新AI產品應用。
