Using Claude, I suddenly realized how to quietly launch Claude Opus 4.7. With the instability and sudden need for KYC in the past few days, I am laying the groundwork for the new model? I was so scared that I quickly went to the official website to see if there were any changes. Take a look at Opus 4.7's own answer: Main upgrade highlights: The focus has been significantly improved in the field of software engineering, especially in the most difficult task - user feedback can be directly handed over to 4.7 for hard core coding work that previously needed to be closely monitored, without so much manual intervention. Visual ability upgrade: Supports high-resolution images with a maximum length of 2576 pixels (approximately 3.75 MP), which is more than three times that of the previous Claude version. It is very useful for scenarios such as screenshot recognition and complex chart data extraction. Add xhigh effort level, between high and max, to provide developers with finer control over inference depth; The default gear in Claude Code has been set to xhigh. There has been a significant improvement in instruction compliance - on the contrary, it should be noted that the prompt previously written may have unexpected results due to the loose execution in 4.6 and strict literal execution in 4.7. It is recommended to re adjust it. Regarding KYC (Network Security Verification): Opus 4.7 is the first testing model of the Glasswing program - Anthropic first tested a new network security barrier (automatically detecting and intercepting high-risk network security requests) on 4.7, laying the groundwork for the subsequent release of a stronger Mythos model. It is indeed required that professional users such as security researchers and penetration testers perform KYC verification and join the Cyber Verification Program in order to use it. Pricing: Same as 4.6, the API inputs $5/M tokens and outputs $25/M tokens without any price increase. In summary, this upgrade has the greatest impact on improving encoding/Agent workflows/high-resolution visual scenes
