OpenAI Launches GPT-4.5 for ChatGPT—It's Huge and Compute-Intensive
GPT-4.5 is here, and OpenAI's newest generative AI model is bigger and more compute-intensive than ever—it's supposedly also better at understanding what ChatGPT users mean with their prompts. Users who want to be part of the first wave to try GPT-4.5, labeled as a research preview, will be required to pay for OpenAI's $200-a-month ChatGPT Pro subscription.
Prior to this launch, 2025 has already been filled with new AI model releases. Anthropic recently put out a hybrid reasoning model for its Claude chatbot. Before that, Chinese researchers at DeepSeek rocked Silicon Valley with their release of a powerful model trained on a tiny budget, prompting OpenAI to drop a 'mini' version of its reasoning model a month ago.
Alongside these new releases, OpenAI promised to invest billions into building the AI infrastructure required to fuel more massive models. And GPT-4.5 is a reiteration of this current strategy from the startup: Bigger is better.
ChatGPT 4.5 is in stark contrast to other recent AI innovations, like DeepSeek's R1, that attempted to match the performance of a frontier model with as few resources as possible. OpenAI still sees a strong path forward through scaling its models. According to researchers who worked on GPT-4.5, this kind of maximalist mindset to model development has captured more of the nuances of human emotions and interactions.
They see the model's size as also potentially helping this iteration hallucinate with less frequency than past releases. 'If you know more things, you don't need to make things up,' says Mia Glaese, who leads OpenAI's alignment team and human data team. Exactly how big or compute-intensive GPT-4.5 is remains unclear—OpenAI declined to share specific numbers.
So, what's it like to use the new model? GPT-4.5 supports the web search and canvas feature as well as uploads of files and images, though it's not yet compatible with the AI Voice Mode.

People Are Asking ChatGPT for Relationship Advice and It's Ending in Disaster
Despite ChatGPT's well-documented issues, people are using it to advise them on relationship issues — and it's going about as well as you'd expect. In a new editorial, Vice advice columnist Sammi Caramela said she had been blissfully unaware of the ChatGPT-as-therapist trend until someone wrote into her work email about it earlier this year. Back in February, an unnamed man told the writer that his girlfriend refused to stop using the chatbot for dating advice and would even bring up things it had told her in arguments. Though Caramela was so shocked that she "nearly choked" on her coffee, the advice-seeker wasn't all that perturbed — and claimed that he found his girlfriend's ChatGPT use fascinating. "I was a bit floored by this confession. I had no idea people were actually turning to AI for advice, much less input on their relationships," the columnist wrote in her more recent piece. "However, the more I explored the topic, the more I realized how common it was to seek help from AI — especially in an era where therapy is an expensive luxury." Intrigued, Caramela found a friend who used the OpenAI chatbot for similar purposes, running relationship issues by it as a "non-biased" sounding board. Eventually, that person realized that ChatGPT wasn't unbiased at all, but rather "seemed to heavily validate her experience, perhaps dangerously so." Similar questions have been posed on the r/ChatGPT subreddit, and as Caramela explained, the consensus over there suggested not only that the chatbot is something of a "yes-man," but also that its propensity to agree with users can be dangerous for people who have mental health issues. "I often and openly write about my struggles with obsessive-compulsive disorder (OCD)," the writer divulged. "If I went to ChatGPT for dating advice and failed to mention how my OCD tends to attack my relationships, I might receive unhelpful, even harmful, input about my relationship." Digger deeper into the world of ChatGPT therapy, Caramela found multiple threads on OCD-related subreddits about the chatbot — and on the forum dedicated to ROCD, or relationship-focused OCD, someone even admitted that the chatbot told them to break up with their partner. "Programs like ChatGPT only speed the OCD cycle up because you can ask question after question for hours trying to gain some sense of certainty," another user responded in the r/ROCD thread. "There's always another 'what if' question with OCD." Like so many poorly-trained human professionals, chatbots aren't equipped to handle the nuance and sensitivity needed in any therapeutic context. Regardless of what OpenAI claims in its marketing, ChatGPT can't be truly empathetic — and if your "therapist" will never be able to have a human-to-human connection, why would you want it to give you dating advice in the first place?

Sam Altman thinks AI will have ‘novel insights' next year
In a new essay published Tuesday called 'The Gentle Singularity,' OpenAI CEO Sam Altman shared his latest vision for how AI will change the human experience over the next 15 years. The essay is a classic example of Altman's futurism: hyping up the promise of AGI — and arguing that his company is quite close to the feat — while simultaneously downplaying its arrival. The OpenAI CEO frequently publishes essays of this nature, cleanly laying out a future in which AGI disrupts our modern conception of work, energy, and the social contract. But often, Altman's essays contain hints about what OpenAI is working on next. At one point in the essay, Altman claimed that next year, in 2026, the world will 'likely see the arrival of [AI] systems that can figure out novel insights.' While this is somewhat vague, OpenAI executives have recently indicated that the company is focused on getting AI models to come up with new, interesting ideas about the world. When announcing OpenAI's o3 and o4-mini AI reasoning models in April, co-founder and President Greg Brockman said these were the first models that scientists had used to generate new, helpful ideas. Altman's blog post suggests that in the coming year, OpenAI itself may ramp up its efforts to develop AI that can generate novel insights. OpenAI certainly wouldn't be the only company focused on this effort — several of OpenAI's competitors have shifted their focus to training AI models that can help scientists come up with new hypotheses, and thus, novel discoveries about the world. In May, Google released a paper on AlphaEvolve, an AI coding agent that the company claims to have generated novel approaches to complex math problems. Another startup backed by former Google CEO Eric Schmidt, FutureHouse, claims its AI agent tool has been capable of making a genuine scientific discovery. In May, Anthropic launched a program to support scientific research. If successful, these companies could automate a key part of the scientific process, and potentially break into massive industries such as drug discovery, material science, and other fields with science at their core.

Boston, MA | REGISTER NOW This wouldn't be the first time Altman has tipped his hat about OpenAI's plans in a blog. In January, Altman wrote another blog post suggesting that 2025 would be the year of agents. His company then proceeded to drop its first three AI agents: Operator, Deep Research, and Codex. But getting AI systems to generate novel insights may be harder than making them agentic. The broader scientific community remains somewhat skeptical of AI's ability to generate genuinely original insights. Earlier this year, Hugging Face's Chief Science Officer Thomas Wolf wrote an essay arguing that modern AI systems cannot ask great questions, which is key to any great scientific breakthrough. Kenneth Stanley, a former OpenAI research lead, also previously told TechCrunch that today's AI models cannot generate novel hypotheses. Stanley is now building out a team at Lila Sciences, a startup that raised $200 million to create an AI-powered laboratory specifically focused on getting AI models to come up with better hypotheses. This is a difficult problem, according to Stanley, because it involves giving AI models a sense for what is creative and interesting. Whether OpenAI truly creates an AI model that is capable of producing novel insights remains to be seen. Still, Altman's essay may feature something familiar — a preview of where OpenAI is likely headed next.

10-year Treasury yield inch higher after U.S. and China agree to trade truce
The 10-year yield on U.S. Treasurys inched higher on Wednesday as U.S. and Chinese officials reached an agreement on trade. At 2.45 a.m. ET, the 10-year Treasury yield was up by 1 basis point at 4.49%. The 2-year yield added the same to arrive at 4.02%. The 30-year yield was also higher by a basis point to 4.95%. One basis point equals 0.01%. Yields and prices move inversely in the bond market, meaning higher prices equal lower yields and vice versa. U.S. Commerce Secretary Howard Lutnick said that he and U.S. Trade Representative Jamieson Greer would return to Washington to "make sure President Trump approves" of the framework agreed with their Chinese counterparts in London. Investors will also be looking out for more insight into the U.S. economy on Wednesday morning as the Bureau of Labor Statistics rolls out May's reading of the consumer price index. Economists polled by Dow Jones call for a 0.2% month-over-month increase, while headline CPI is anticipated to have grown 2.4% from 12 months earlier. A hot report could spook investors who are already on edge over inflationary pressures.
