Claude-Haiku-3

Claude Haiku 3 represents Anthropic's approach to delivering the core Claude experience in a lightweight, efficient package. Positioned as the speed- and cost-optimized member of the Claude family, Haiku is engineered to handle basic, real-time multimodal AI tasks without the computational overhead of larger models. It supports processing text, images, and PDFs, with file attachments and tool calling expanding its practical utility for developers building responsive applications.

The Haiku series has shown meaningful iterative improvement over time. The subsequent Haiku 3.5 release demonstrated that the Haiku lineage could significantly close the capability gap with larger models—outperforming the previous-generation flagship Claude 3 Opus on many benchmarks while remaining roughly 15 times less expensive to run. This progression suggests a deliberate cultivation strategy within Anthropic's model family, where efficiency-focused designs continue gaining capability through targeted updates, making the Haiku line increasingly attractive for developers who need reliable performance without premium pricing.
