Anthropic has updated its AI offerings by making Claude Opus 5.5 the default model across all paid subscription plans, according to The Decoder. This change reflects the company’s commitment to improving user experience and model performance.

Alongside this update, Anthropic published a new guide advising users to adjust their prompting strategies. The guide suggests moving away from phrases like "think hard" and recommends starting prompts at a Medium effort level to enhance interaction quality with the AI.

For Japanese FX, crypto, and equities market participants, these developments highlight the ongoing evolution of AI tools that can support more nuanced data analysis and decision-making processes in a rapidly changing financial environment.
