Leaked Vertex AI logs showed claude-sonnet-5@20260203 last weekend (Feb 3 date string), and Anthropic’s running a massive Super Bowl campaign this week with the “Ads are coming to AI. But not to Claude” angle—directly dunking on OpenAI’s ChatGPT ad tier. Super Bowl timing makes perfect sense for a drop: max exposure during the biggest marketing event of the year, Q1 enterprise budget window, and “Sonnet” works perfectly as a consumer brand hook. Early testing leaks claim 80.9-83.3% on SWE-Bench (matching/beating Opus 4.5), competitive math performance, and stronger coding than Opus 4.5 in some workflows. Codename is allegedly “Fennec.” Anthropic’s been uncharacteristically aggressive lately, things like F1 sponsorship, Cowork launch that tanked tech stocks $285B over automation fears, and now dropping millions on Super Bowl ads. If they’re spending that kind of cash, they need something real to back it up. What do you all think? Are they dropping a bomb today? submitted by /u/Infinite-Club4374
