Perplexity AI, a company that Jeff Bezos supports, is planning to put advertisements in search results like Google does. Perplexity AI has been very popular with many downloads and a lot of search queries. They will have a special way for advertisers to pay, called CPM. The company will start with ads about technology, health, and more. People using the app can click on ads to learn more.

A New AI developed with the backings of Jeff Bezos could pose a significant challenge to Google's search engine dominance. According to sources, the new AI, named Perplexity AI, already has a sizable user base and has been downloaded over 2 million times. It has also reportedly managed to handle more than 230 million queries monthly. However, the new venture seeks to integrate ads into its search results, much like Google does, which has raised a few eyebrows. The advertising model Perplexity AI intends to follow is said to be a cost-per-thousand-implications (CPM) approach, with CPM prices that could exceed $50. Perplexity AI is looking to initiate advertising categories such as technology, health, finance, and food and beverages. The source further revealed that advertisers could have the option of sponsoring 'related questions' that appear below answers and can purchase display ads next to a Perplexity- generated response. Despite all these advancements, the article points out that Perplexity AI has had its fair share of backlash over its content- sourcing methods, with allegations of plagiarism being levied against the AI startup. Forbes and Wired reportedly found instances of their content appearing on Perplexity without proper attribution. In response, Perplexity AI made changes to its Pages feature and updated its responses to better cite sources.

1. **Perplexity AI** (RECOMMENDED): With a strong backing from Jeff Bezos and its remarkable growth rate, Perplexity AI seems to be a promising investment. It has managed to garner a significant user base, despite allegations of content sourcing issues. The incorporation of ads in search results and the new revenue-sharing model could be major growth drivers. However, the potential backlash and regulatory issues can't be ignored.

2. **OpenAI** (CAUTIOUS): As the creator of the popular AI model, ChatGPT, OpenAI is making waves in the tech industry. The recent announcement of its entry into the search category with the prototype SearchGPT hints at its potential for growth. However, the technology and its applications are still in the early stages of development, and the company has yet to establish a significant market presence. Hence, a cautious approach is advised before investing.

3. **Alphabet Inc. (Google)** (NEUTRAL): The tech giant has been facing competition from the up and coming AI models like Perplexity AI and SearchGPT. Its recent move to launch 'AI Overviews' in search seems like an attempt to counter the challenge. Google is a stable investment with a diverse portfolio, but its relatively slower pace of innovation compared to new AI models might not be as lucrative in the long run.

4. **Amazon Web Services (AWS)** (WATCH AND LEARN): As a leader in cloud computing and AI development, AWS is constantly innovating. The CEO's prediction that AI could soon dominate coding is indicative of the potential for growth in this area. However, as an established player, AWS may not be as agile in adapting to the rapidly evolving AI landscape. It's worth keeping an eye on their developments, but not necessarily an immediate investment opportunity.

5. **Cannabinoid AI** (AVOID): Despite its claims of being the first AI model to detect cannabinoids in real-time, Cannabinoid AI is relatively unknown and untested. The technology and its potential applications are not yet proven, and investing in this AI model would be considered a high-risk, high-reward scenario.
