前几天的 Google I/O 大会上，Google 宣布，其 Model Garden 和 Generative AI Studio 已可在 GCP Vertex AI 上公开预览，包括访问 PaLM for Text and Chat 和 Embeddings API for Text。

这一 Generative AI 新闻令人振奋。那么如何体验呢？快跟随马可君，使用您的 Google Cloud 账号登陆试用（如需账号，可点击阅读原文联系我们，快速获取 ），快速尝鲜吧！

打开 Google Cloud Console：

https://console.cloud.google.com/

前往 Vertext AI：

https://console.cloud.google.com/vertex-ai

在左侧菜单栏中，我们已经可以看到 Model Garden 和 Generative AI Studio 的相关选项。

在 Model Garden 中， Google 预置了众多模型，方便用户快速使用。

在 Generative AI Studio 中，用户目前可以使用 Language 和 Speech 的功能，但图片生成功能还需要再耐心等等。

那么如何通过编程的方式进行调用呢？

LONDON, England (Reuters) -- Harry Potter star Daniel Radcliffe gains access to a reported £20 million ($41.1 million) fortune as he turns 18 on Monday, but he insists the money won\'t cast a spell on him. Daniel Radcliffe as Harry Potter in "Harry Potter and the Order of the Phoenix" To the disappointment of gossip columnists around the world, the young actor says he has no plans to fritter his cash away on fast cars, drink and celebrity parties. "I don\'t plan to be one of those people who, as soon as they turn 18, suddenly buy themselves a massive sports car collection or something similar," he told an Australian interviewer earlier this month. "I don\'t think I\'ll be particularly extravagant. "The things I like buying are things that cost about 10 pounds -- books and CDs and DVDs." At 18, Radcliffe will be able to gamble in a casino, buy a drink in a pub or see the horror film "Hostel: Part II," currently six places below his number one movie on the UK box office chart. Details of how he\'ll mark his landmark birthday are under wraps. His agent and publicist had no comment on his plans. "I\'ll definitely have some sort of party," he said in an interview. "Hopefully none of you will be reading about it." Radcliffe\'s earnings from the first five Potter films have been held in a trust fund which he has not been able to touch. Despite his growing fame and riches, the actor says he is keeping his feet firmly on the ground. "People are always looking to say \'kid star goes off the rails,\'" he told reporters last month. "But I try very hard not to go that way because it would be too easy for them." His latest outing as the boy wizard in "Harry Potter and the Order of the Phoenix" is breaking records on both sides of the Atlantic and he will reprise the role in the last two films. Watch I-Reporter give her review of Potter\'s latest » . There is life beyond Potter, however. The Londoner has filmed a TV movie called "My Boy Jack," about author Rudyard Kipling and his son, due for release later this year. He will also appear in "December Boys," an Australian film about four boys who escape an orphanage. Earlier this year, he made his stage debut playing a tortured teenager in Peter Shaffer\'s "Equus." Meanwhile, he is braced for even closer media scrutiny now that he\'s legally an adult: "I just think I\'m going to be more sort of fair game," he told Reuters. E-mail to a friend .
