When will Anthropic release a model called Claude 3.5 Opus and make it generally available?

Claude 3.5 Sonnet was released on June 20. Regarding future plans, Anthropic stated that "Our aim is to substantially improve the tradeoff curve between intelligence, speed, and cost every few months. To complete the Claude 3.5 model family, we’ll be releasing Claude 3.5 Haiku and Claude 3.5 Opus later this year."

This market resolves to December 2024 or later if Opus has not been released by the end of November (i.e. this market will not N/A if Opus is known to be cancelled).
