on october 25th, many people attributed the recent wave of video-coding to the re-compilation and re-compilation of the game Anthropic Claude Opus 5.5. And now, a large number of users suddenly feedback: Opus 5.5's ability to “reverse everything” has probably been quietly eroded。
One thing is clear: Anthropic did not announce and publish a new version of Opus 5.5. However, on October 21, the company sent a series of updates to multiple Claude related products. At this point, it coincided with the post that appeared in Reddit r/Claude's community on October 21stReverse ProjectCapacity constraints。
Several users responded that when Claude Opus 5.5 was instructed to reverse any intellectual property-protected content, the security fence would trigger the interception in the middle of the output. In one example, Claude responded that “safe verification has terminated this answer” and that even a different wording will no longer generate the corresponding analytical content。
But there are also some users who disagree. The view was expressed that using Claude for reverse engineering would have had a precarious outcome, “the sorter itself is sensitive, and it depends on luck. However, users holding this view are a minority。
Does Anthropic change the model capacity without updating the patch? The answer is yes. This company often does so, so there is a high probability that the reverse-related capability of Opus 5.5 has been quietly adjusted without informing users。
And as for Anthropic, it's not hard to guess why he's taking the initiative to lower the model capacity. 1AI noted that the change was linked to an event by users on platform X: Claude was used to modify the firmware of the three-star television permanent microphone. This may not be the last straw to crush the camel, but a series of events -- the transfer of games to browsers with Claude, and commercial programs like Adobe, Microsoft Office, are being used to create a model, which is likely to influence Anthony’s decision-making。
