Anthropic’s IPO filing lays bare the cost of the AI race

Claude Pro, Anthropic's more expensive plan, costs $20 a month for access to larger models and additional features. However, Anthropic's cheapest model, Haiku 5.5, recently saw a significant price cut on the API, making it a more affordable option for many everyday AI tasks. Haiku 5.5 charges per-token pricing instead of a flat fee, with input at $0.10 per million tokens and output at $0.50.

This model was introduced in October for faster, high-volume work and offers adaptive thinking with an adjustable effort setting. The price cut makes Haiku 5.5 a tenth of the cost of its predecessor, and Anthropic estimates a real saving of around 75%. When tested in a free desktop app, Haiku 5.5 proved capable of replacing a Claude desktop setup, generating detailed explanations and handling complex tasks like batch-renaming files.

The main drawback is that Haiku 5.5 struggles with complex reasoning and multi-step tasks, making it better suited for simpler tasks. With a busy workday peaking at around 3,000 input tokens and under 800 output tokens, the daily cost is estimated at around $0.33, totaling roughly $7.30 for an eight-hour workday.
