Balanced Claude model for coding, analysis, agent workflows, and cost control
Claude Sonnet 4 by anthropic is offered by 15 providers on this page. Its reference price is $3.00 per 1M input tokens and $15.00 per 1M output tokens. The lowest paid channel is Poe at $2.60 / $13.00 per 1M, about 1.2× below the reference price. That channel is a third-party gateway, so confirm its availability and rate limits before depending on it.
The context window is 200,000 tokens at the reference host, but hosts report different limits, from 200,000 to 1,000,000, so the usable window depends on the provider you pick. It supports reasoning and tool use. 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 2025-03-31.
