Anthropic has launched Claude Haiku 5.5, an upgraded version of its smallest AI model, now faster and costing approximately 75% less to operate than its predecessor. The new model is optimized for high-volume, cost-sensitive tasks such as summaries, database queries, and customer support, and is part of a broader update that includes price reductions across other Claude models.
Claude Haiku 5.5 has been launched, offering a significant reduction in cost—about 75% less than its predecessor—while delivering faster performance. It is optimized for high-volume, repetitive tasks such as summaries, database queries, and classification, and pairs effectively with Opus 5.5 and Sonnet 5.5 for coding applications. The update also includes price reductions for related models and new API credits for subscribers, aiming to enhance value for users building on the Claude platform.
Anthropic released Claude Sonnet 5.5, the second model in its Claude 5.5 lineup after Opus 5.5. The company says it runs over 30% faster and costs up to 30% less per task than Sonnet 5, while keeping the same per-token pricing, and jumps from 10.3% to 70.6% on the Terminal-Bench 4.0 agentic coding evaluation. A third model, Claude Haiku 5.5, is planned for release in the coming weeks.
A Show HN project puts four AI models in a head-to-head Pong match, running each in its own lane where the ball's speed depends entirely on that model's response time. The setup contrasts Jev, a typed-decision model, against chat-based models like GPT-5.6 and Claude Haiku, using Pong specifically because it exposes how chat models struggle with fast, continuous decision-making.
