Why do teams often compare Claude Sonnet 4.6 with GPT-5 instead of GPT-4o?

Choose Sonnet when you want the strong Claude family quality profile but need better cost-efficiency for repeated production use. Choose Opus when top-end output quality matters more than cost.

What makes this page a long-term index page rather than a campaign page?

This page is designed as a maintained pricing and decision asset for a head term with ongoing commercial intent, not just a temporary paid-traffic variant.

What is Claude Sonnet 4.6 not ideal for?

It is not the strongest fit when the only goal is lowest-cost throughput or when the workflow is heavily centered on richer audio or video-native multimodal input.
