Claude Haiku 4.5 API in Australia

In Australian dollars, the currency your card is charged in, with the published US dollar rate beside each.

For scale: 1,000 requests of about 3,000 tokens in and 1,000 out cost A$12.11 — a long prompt and a page of answer each. Every rate is published and stays the same from one request to the next. See every model.

Prices are our published US dollar rates converted at A$1.47 to the dollar, our rate for October — the same rate your card is charged.

Haiku 4.5 is the quick one. When it came out in October 2025 it matched the coding of the then-current Sonnet 4 at a third of the cost and more than twice the speed, scoring 73.3% on SWE-bench Verified. It was also the first Haiku that could think before answering and operate a computer.

Anthropic pitches it as a worker a bigger model directs — many Haikus running in parallel under one Opus — and for anything a customer waits on, like live chat. It is the oldest model in Anthropic’s current line, and that shows in what it knows.

• Live chat and customer-support agents, where speed matters most.
• Sub-agents running in parallel under a larger model.
• High-volume sorting, tagging and data extraction.
• Quick coding help and prototypes.

• Its knowledge is old: reliable to February 2025, more than a year behind the 5.x models.
• Anthropic only guarantees it until mid-October 2026. For new work, plan for a successor.
• Smaller limits than newer models: 200K tokens of context and 64K of output.
