Our take
For those requiring high-volume summarisation or subagent operations, Claude Haiku 5.5 presents a focused option. Its 1,000,000-token context window, larger than most comparable models, facilitates processing extensive inputs, while its low API price of $0.1 per 1M input tokens positions it as a cost-effective choice, cheaper than approximately 75% of similar models. Unlike broader AI assistants such as ChatGPT or Gemini, this model emphasizes specific, cost-sensitive tasks. It incorporates features like vision capabilities for image input and structured JSON outputs, alongside a built-in reasoning mode for more complex problems. This makes it particularly suited for developers and businesses needing to integrate AI for research and writing tasks at scale, where cost efficiency and large context handling are paramount. However, the absence of a free tier means it is not suitable for casual or exploratory use without incurring costs.
