Code with Claude developer conference today — Claude Jupiter red teaming underway

Summary

Anthropic hosts its Code with Claude developer conference in San Francisco today (May 6), with London and Tokyo dates following. Last year’s event saw the launch of Claude Sonnet 4 and Opus 4. Claude Jupiter V1 P has been spotted in internal red teaming, following Anthropic’s pattern of using planet codenames for pre-release safety probes. If released on schedule, the model would surface across the Anthropic Platform, Claude Code, and consumer apps.

Implications

• A new model launch at Code with Claude would restart the capability race during what has been a distribution-focused period
• The Jupiter codename suggests a flagship-tier model — potentially the Opus 4.8 or a new family designation
• Feeds the distribution machine thread: the conference is a developer acquisition channel, the model launch is the draw
• Timing is significant: Gemini 3.2 Flash leaked yesterday, Google I/O is May 19, OpenAI’s GPT-5.5 launched April 23. All three vendors will have shipped major models within a month
