About

Claude Haiku 5.5 is an Anthropic AI model designed for high-volume, latency-sensitive workloads such as classification, routing, extraction, and subagent tasks. The model supports adaptive thinking, allowing it to determine when and how much reasoning to perform based on the request. Developers can use the effort parameter to balance response quality against speed and cost, while adaptive thinking is enabled by default. Claude Haiku 5.5 provides a 1 million token context window and supports outputs of up to 128,000 tokens, increasing from the 200,000-token context window and 64,000-token output limit of Claude Haiku 4.5. It also supports browser use through the Claude API and Google Cloud for workflows that require interaction with web-based environments. Claude Haiku 5.5 uses Anthropic's newer tokenizer introduced with Claude 4.7 and later models, which results in the same text using approximately 30% more tokens than with Claude Haiku 4.5.

About

MultiO is a web-based AI workspace that brings models from providers including OpenAI, Anthropic, Google, xAI and Meta into one subscription. Auto routing sends each message to a cost-efficient model suited to the request; users can also choose or pin a model, or compare responses from up to three models side by side. Each message includes a receipt showing its exact token charge at published rates. The workspace includes deep research with citations, image and video generation, live voice, projects, and documents with Word, Excel and PDF export. Its coding assistant works with GitHub repositories and can open pull requests. Developers can also use MultiO's API. A no-card free trial includes 3,000,000 tokens, and the Pro plan costs $20 per month.

Pros & Cons from Real Users

Pros

  • Claude Haiku 5.5 is impressively fast while still being capable enough for a wide range of everyday AI tasks. I found it particularly good for quick coding work, summaries, classification, and other high-volume tasks where responsiveness matters. It's a substantial improvement over Haiku 4.5 and offers a great balance between intelligence, speed, and cost.

Cons

  • Haiku 5.5 is still designed as the lightweight model in the Claude lineup, and that becomes noticeable on more complicated reasoning and long-running tasks. For difficult coding problems or work that requires a lot of judgment, I'd still rather use Sonnet 5.5 or Opus 5.5.
