OpenAI has announced several new updates, including the introduction of Claude-like artifacts, a feature previously unique to Anthropic's Claude. This move is seen as a direct response to Anthropic's advancements. OpenAI's updates, led by CEO Sam Altman, also include a real-time API, advanced voice mode, Dalle4, Sora, Search GPT, canvas, and reasoning AI, aimed at enhancing the user experience and encouraging users to sign up for ChatGPT Plus. The competition between OpenAI and Anthropic is expected to drive further technological improvements, with Anthropic possibly releasing Opus 3.5 in response.
