Salio(@Mr_Salio):🚨 OPUS 5.5 just leaked again anthropic/claude-wafer-eap appeared in a Vals PR It was tested on Terminal-Bench Max compute effort spent ~10 minutes reasoning before the first tool call One run lasted 598 seconds before failing A newer version reportedly progressed further on the same task This looks like another strong sign that Opus 5.5 is close Anthropic is definitely cooking something🔥
