Top 5 stories of the week: Generative AI market heating up (even more)

Join top executives in San Francisco on July 11-12, to hear how leaders are integrating and optimizing AI investments for success. Once again, AI news topped the tech headlines this week -- in particular, the generative AI market is becoming increasingly competitive, with both new and well-established enterprises making significant investments. This includes GitHub's new Copilot X; startup Codium AI's new code-integrity tool TestGPT; and a whole slew of new tools, services and capabilities from Nvidia. Still, skepticism remains, with OpenAI's CEO Sam Altman even expressing apprehension. Not topping the list (but still noteworthy AI news): Databricks released its GPT-like Dolly; OpenAI turned ChatGPT into a platform overnight with several new plugins; OpenAI rival Character AI announced a $1 billion valuation; and Google released Bard, a competitor to ChatGPT, Claude and Bing Chat.
