Anthropic新模型杀疯了！成本直降 2/3、性能直逼GPT-5，用户实测：比“吹”的还强，速度超 Sonnet 3.5 倍

Core Viewpoint - Anthropic has launched the Claude Haiku 4.5 model, which is positioned as a cost-effective alternative to its larger models, offering performance close to Sonnet 4 at one-third the cost and double the speed [2][12]. Performance and Features - Haiku 4.5 is a hybrid reasoning model that can adjust its computational resources based on the request, allowing for both quick responses and more complex outputs when needed [3][4]. - The model can handle multi-modal prompts with up to 200,000 tokens and generate responses of up to 64,000 tokens [3]. - In benchmark tests, Haiku 4.5 scored 73% on SWE-bench Verified and 41% on Terminal-Bench, showing competitive performance with Sonnet 4 and GPT-5 [4][7]. Cost and Accessibility - Haiku 4.5 is priced at $1 per million input tokens and $5 per million output tokens, significantly cheaper than Sonnet 4.5, which costs $3 and $15 respectively [9]. - The model is now available across all platforms, enhancing accessibility for users [9]. Market Impact and Growth - Anthropic's monthly run rate is approaching $7 billion, with a target of $20 billion to $26 billion in annual revenue by 2026, indicating rapid growth [18]. - The company serves over 300,000 enterprise clients, with enterprise products accounting for about 80% of total revenue [18]. Strategic Positioning - Haiku 4.5 is designed to complement Sonnet 4.5, allowing for a division of tasks where Haiku handles simpler tasks and Sonnet focuses on complex planning [13][14]. - The model's lightweight nature facilitates the parallel deployment of multiple Haiku instances, enhancing efficiency in AI workflows [13]. User Feedback and Adoption - Early adopters have reported positive outcomes, with some stating that Haiku 4.5 achieves 90% of Sonnet 4.5's performance while being faster and more cost-effective [15]. - Users have noted that Haiku 4.5 blurs the lines between speed, cost, and quality, indicating a shift in expectations for AI models [15][16]. Industry Trends - The rapid decline in AI costs, with a reported two-thirds reduction in five months, suggests a significant shift in the economic logic of AI [17][19]. - Anthropic's valuation stands at $183 billion, positioning it competitively against major players like OpenAI and Google [20].
