Anthropic Unveils Its Smartest 'Hybrid Reasoning' AI Model Yet

June 2, 2025

Anthropic has just unveiled Claude 3.7 Sonnet, marking the debut of its first "hybrid reasoning model." This groundbreaking model is designed to tackle more intricate challenges and surpasses earlier iterations when it comes to tasks like mathematics and coding.

To complement this advancement, Anthropic is also launching a "limited research preview" of Claude Code, an agentic coding tool. While Anthropic already powers AI coding solutions like Cursor, Claude Code is being marketed as an interactive partner capable of searching and reading code, modifying files, writing and running tests, pushing code to GitHub, and utilizing command-line tools.

Claude 3.7 Sonnet will be accessible starting Monday within the Claude app and via Anthropic’s API, Amazon Bedrock, and Google Cloud’s Vertex AI. Pricing remains consistent with its predecessor, 3.5 Sonnet, at $3 per million input tokens and $15 per million output tokens.

Unlike competitors such as OpenAI, which offer distinct reasoning models, Anthropic emphasizes integrating reasoning capabilities directly into the model itself. As Dianne Penn, Anthropic’s product research lead, explained to The Verge, “We fundamentally believe that reasoning is a feature of the AI rather than something entirely separate.” For instance, Claude shouldn’t struggle much with straightforward queries like “What time is it?” but excels at handling complex prompts like planning a two-week trip to Italy while factoring in weather conditions.

Penn noted that Claude 3.7 Sonnet shows marked improvement in agentic coding, finance, and legal matters. Although Claude doesn’t yet support real-time web searches—a capability present in other models—it boasts a knowledge cutoff date of October 2024, making it more current. Developers can influence how the model operates through its scratchpad feature and specify exact response times. “Sometimes,” said Anthropic’s VP of product, Michael Gerstenhaber, “the developer simply needs to indicate that it shouldn’t take longer than 200 milliseconds to answer this question,” highlighting a strategic product decision.

Internally, Anthropic staff have utilized the new model to design front-end website interfaces, create interactive games, and engage in up to 45 minutes of coding activities, such as building test sets and refining test cases iteratively, according to Penn.

Penn mentioned that Anthropic evaluates its models’ capabilities by having them navigate an old-school Pokémon video game, mapping the model’s API to a controller interface. While Claude 3.5 Sonnet struggled to leave Pallet Town initially, Claude 3.7 successfully defeated several gym leaders.

Elon Musk’s recent unveiling of Grok-3 last week underscored the rapid pace of the AI model competition. For now, Anthropic stands ahead thanks to Claude 3.7 Sonnet’s impressive performance. Its release hints at a future where a single model handles every task, rather than requiring specialized tools for different functions.

Hybrid reasoning sounds like a game-changer for coding tasks, but I'm curious about the real-world cost. The article mentions new pricing tiers—will this make AI development more accessible or just widen the gap between big labs and indie researchers? 🤔

¡Otra IA 'más inteligente'? 😅 La verdad es que estos lanzamientos ya se sienten como una rutina mensual. Me interesa eso del "razonamiento híbrido", pero me pregunto: ¿realmente resolverá problemas del mundo real de forma más confiable, o solo será mejor en benchmarks artificiales? Veremos cómo se compara en usabilidad con GPT-o.

ハイブリッド推論モデルって何?数学やコーディングが得意なのはすごいけど、AIが複雑な問題を解けるようになると、人間の仕事が奪われるんじゃないかと少し心配😅 でも技術の進歩は止められないから、うまく付き合っていくしかないですね。
