ANTHROPIC INTRODUCES CHEAPER, MORE POWERFUL, MORE EFFICIENT OPUS 4.5 MODEL

Summary from the TLDR newsletter

Anthropic has released its latest frontier model, Opus 4.5. The model brings improvements in coding performance and user experience. The Opus 4.5 API costs $5 per million input tokens and $25 per million output tokens. Anthropic's developer platform now includes a new 'effort' parameter that allows developers to more precisely tune the balance between efficacy and token usage. Claude Code is now available in the desktop Claude apps.
