Anthropic Launches Claude Haiku 4.5: A New Era of AI Innovation

Anthropic has introduced Claude Haiku 4.5, marking a significant advancement in AI innovation. This latest model, available today, delivers superior performance at reduced costs and increased speed. While Claude Sonnet 4 was recognized as a leading model just five months ago, Haiku 4.5 rivals its capabilities, offering a cost of one-third and speed that is more than double.
Key Features of Claude Haiku 4.5
Claude Haiku 4.5 significantly enhances user experience, especially for tasks requiring low latency. Here are the most notable features:
- Cost-effective: Pricing at $1/$5 per million input and output tokens.
- High intelligence: Achieves near front-line performance in coding tasks.
- Speed: Up to 4-5 times faster than its predecessor, Sonnet 4.5.
- Improved responsiveness: Ideal for real-time applications like chat assistants and customer service.
Increased Performance Metrics
Early evaluations show that Claude Haiku 4.5 surpasses previous models in various tasks:
- It achieved 90% of Sonnet 4.5’s performance in Augment’s agentic coding evaluation.
- For instruction-following tasks, it recorded 65% accuracy, significantly higher than Sonnet 4.5’s 44%.
Enhanced Safety Features
A notable aspect of Claude Haiku 4.5 is its commitment to safety. Rigorous testing indicated:
- Significantly lower rates of misaligned behaviors compared to Claude Sonnet 4.5 and Claude Opus 4.1.
- It poses limited risks regarding the potential production of chemical, biological, radiological, and nuclear weapons.
As a result, it has been released under the AI Safety Level 2 (ASL-2) standard, which is less restrictive than the ASL-3 classification that applies to Sonnet 4.5 and Opus 4.1.
Use Cases and Availability
Claude Haiku 4.5 is already available across various platforms, including:
- Claude Code
- Amazon Bedrock
- Google Cloud’s Vertex AI
Developers can utilize Haiku 4.5 through the Claude API, enhancing productivity and efficiency in coding tasks.
In summary, Claude Haiku 4.5 signifies a meaningful leap in AI functionality. Its blend of intelligence, speed, and safety makes it an attractive option for developers and businesses looking to leverage advanced AI capabilities at a competitive price.
