FAQs

Model selection, limitations, and access.

What Is Claude Haiku 5.5?+

Anthropic’s small model targets high-volume, latency-sensitive work, combining adaptive reasoning with text and image understanding.

When Should I Choose Claude Haiku 5.5?+

Choose it for classification, extraction, summaries, live support, and narrow subagent tasks where response time and repeated-call cost matter.

What Are Its Main Tradeoffs?+

Anthropic recommends larger models for complex agentic coding. Higher effort can increase cost and latency; prompts above 100K tokens also enter a higher pricing tier.

How Do I Use Claude Haiku 5.5 Through TokenHub?+

Use the identifier and endpoint documented by TokenHub after confirming access. Anthropic’s direct API ID is claude-haiku-5-5; do not assume it matches a TokenHub alias.

How Is Claude Haiku 5.5 Priced?+

Anthropic lists $0.10 input/$0.50 output per million tokens for prompts up to 100K tokens, and $0.50/$2.50 above that threshold. TokenHub rates may differ.
