OpenAI Unveils GPT-4.5 Preview

OpenAI has launched GPT-4.5, its latest AI model, marking a notable update to ChatGPT. Today, the model was launched as a research preview for ChatGPT Pro users. Next week, it will expand to Plus and Team subscribers. The company describes it as its largest model yet.

GPT-4.5 was trained with more computing power and data than any previous release, aiming to refine how AI interacts with humans.

Key highlights include improved emotional intelligence, which allows it to pick up on subtle cues and respond more empathetically. It also reduces hallucinations and excels at connecting ideas. So, it should be a more potent tool for problem-solving.

Sam Altman called it the "first model that feels like talking to a thoughtful person." In his opinion, chatbots are now moving towards more intuitive conversations. However, it’s not a complete leap to GPT-5. You can think of it as a bridge, with the upcoming GPT-5 to blend this tech with reasoning models like o3.

You can compare this model with others on the OpenAI website.

Ambiguous Reception

Not everyone is happy with GPT-4.5.

One comment out of dozens of similar ones.

The first thing that grabbed my attention was that the Explore page on X changed from “GPT-4.5 Release” to “GPT-4.5: A Leap in AI or a Step Back?” Many users began to write negative comments based on their impressions. They believe the difference between GPT-4o and GPT-4.5 is not that big.

But things got worse from there. Because the community seems to be right.

Andrej Karpathy (Co-founder and former Chief Scientist of OpenAI) made an interactive comparison of two models, the new one and its predecessor. As blind testing with users showed, in 4 out of 5 cases, people preferred the responses from the old GPT-4o. He also noted that the new model (because of its size) is much slower.

That is, it loses both quality and speed.

Right now, I am not prepared to share my opinion on this release.
In the coming days, we at Creators' AI will be actively testing GPT-4.5 and will get back to you with our verdict very soon. So stay tuned!

Perplexity Develops 'Comet' Browser for Agentic Search

Perplexity AI has announced Comet, a new web browser designed to enhance agentic search capabilities. Comet promises to provide users with a more interactive and intuitive experience. We don't have any other details; the company has yet to share the features or look of its next product. However, you can already join the waiting list.

Funnily enough, Perplexity CEO Aravind Srinivas asked users on X what features they would like to see in the new browser. It makes me wonder if the startup isn't sure of the result. Nevertheless, I'm looking forward to trying it out!

Amazon Launches Alexa+

Amazon has unveiled Alexa+, its next-generation assistant based on Bedrock's LLMs. The upgraded Alexa features free-flowing conversations and integrates with over 20,000 services and devices. According to the company, this model also introduces proactive suggestions and cross-device continuity via a new mobile app and browser interface. Priced at $19.99/mo, it will be free for Amazon Prime members.

In its press release, Amazon forgot to mention a key fact: the new Alexa uses Anthropic's Claude as a major model. The partners have worked on the assistant for the past year.

Anthropic Debuts Claude 3.7 with Hybrid Reasoning

Speaking of Anthropic. Earlier this week, the startup released Claude 3.7 Sonnet, its first hybrid reasoning model capable of instant responses or extended, visible problem-solving. The model excels in coding and front-end, with a new Claude Code tool enabling terminal-based agentic coding. Claude 3.7 is available across all Claude tiers (including free) and cloud platforms like Amazon Bedrock.

All the big AI players have immersed themselves in “reasoning.”

Lex Page — Simple writing tool with AI Editor

Lex Page is a new platform that combines the functionality of a word processor with AI. Its goal is to offer an alternative to Google Docs (and other word processors) with a simple design but many smart features. Using GPT-4, Lex Page generates relevant recommendations for editing and improving text. You can think of it as a personal editor and proofreader that you can call (or silence) when needed.
