Last year, AI startup Anthropic failed to deliver a successor to its top-of-the-line Claude 3 Opus model. Months after announcing that a next-gen model, Claude 3.5 Opus, would by released by the end of 2024, Anthropic scrapped all mention of the model from its developer documentation. (According to one report, Anthropic did finish training Claude 3.5 Opus sometime last year, but decided that releasing it didn’t make economic sense.)
Reportedly, Google and OpenAI have also suffered setbacks with their flagship models in recent months.
