Flagship Claude model for deep reasoning, coding, and long-horizon agents
Claude Opus 4.5 by anthropic is offered by 23 providers on this page. Its official list price is $5.00 per 1M input tokens and $25.00 per 1M output tokens. The lowest paid channel is QiHang at $0.71 / $3.57 per 1M, about 8.5× below the list price. That channel is a third-party gateway, so confirm its availability and rate limits before depending on it.
Artificial Analysis rates it 41.9 on the Intelligence Index. Against its lowest blended price of $1.43 per 1M, that is roughly 29 index points per dollar, which is the value ratio the leaderboards rank on. Median output speed is 46 tokens per second, with 13.31s to the first token.
The context window is 200,000 tokens at the reference host, but hosts report different limits, from 196,608 to 200,000, so the usable window depends on the provider you pick. It supports reasoning, tool use, and structured output. Accepted input modalities are Text, Image, and PDF. Providers report the capability flags inconsistently, so verify a specific feature against the host you plan to use. Its training knowledge cuts off at 2025-05.
Quality is independently evaluated by Artificial Analysis. Speed/latency are model-level medians.
