Anthropic has launched Claude Sonnet 5, the latest iteration of its AI language model. While the token pricing remains unchanged from previous versions, the model consumes approximately 40% more tokens per task, effectively increasing the real operational cost for users.

According to The Decoder, Claude Sonnet 5 earned 53 points, ranking fifth on the Artificial Analysis Intelligence Index. Despite its improved performance, the increased token consumption per task suggests a trade-off between efficiency and cost that users should consider.

For Japanese investors and traders active in AI-driven markets, understanding these cost dynamics is crucial as token usage directly impacts expenses in FX, crypto, and equities platforms leveraging such models.
