Anthropic And OpenAI Are Facing Stiff Competition From Open-Weight Competitors. They Are Releasing Cheaper Models.

Anthropic and OpenAI announced new cheaper models as they face fierce competition from open-weight introduced GPT-6 Sol and GPT-6 Luna, cutting API prices by 50%, while Anthropic unveiled Claude Opus 5.5, saying it will cost 40% less to run than Opus Penn, head of product management, research and labs at Anthropic, told CNBC that the company is seeking to continue innovating on "how to make that thinking, how to make the answering more efficient, so it uses less tokens depending on your effort setting."The releases are the first ones since the companies warned about the dangers of not pacing AI development. The CEOs of both companies, Sam Altman and Dario Amodei, are also expected to address the United Nations Security Council this week as concerns as concerns about the potential dangers of AI Security Council is scheduled to meet on Wednesday to discuss AI and international security, bringing some of the industry's most influential executives and researchers into a forum traditionally focused on wars, nuclear proliferation and threats to global from Chinese AI companies DeepSeek and Moonshot have also been invited to participate, although DeepSeek founder Liang Wenfeng is not expected to and Amodei are expected to be joined by Hugging Face CEO Clément Delangue and Yoshua Bengio, the Université de Montréal professor and prominent AI researcher who co-chairs the U.N.'s Independent International Scientific Panel on Artificial Amodei and Altman have backed "pacing" frontier development and stronger security measures. The two executives have argued that slowing certain advances does not mean stopping AI innovation, but rather allowing safeguards and alignment research to catch up with rapidly expanding Donald Trump has rejected the notion, saying on Tuesday that his administration won't seek to pace at the United Nations General Assembly, Trump said he's "not going to stifle growth of something that will be bigger than the industrial revolution.""Many say it will be bigger, or than the internet itself. We'll be very careful. We already have the DOJ and other law enforcement bodies that will rein things in if we have to. We'll only encourage super intelligence," Trump added, in reference to his decision to create an "AI Force" that will include the appointment of an "AI Czar."In a lengthy social media post this weekend, Trump framed concerns about AI development as partisan politics. "Over the years, there have been many Hoaxes, all generated by the Radical Left Dumocrats, for purposes of destroying our Country. RUSSIA, RUSSIA, RUSSIA, UKRAINE, UKRAINE, UKRAINE, Global Warming, Impeachment Hoax #1, Impeachment Hoax #2, Men in Women's Sports, Transgender for Everyone, and now, the decimation, or destruction, of AI," Trump wrote."We will not in any way hinder or stifle the Growth of this incredible Industry. Rather, we will cherish it, help it, and watch over it, as it grows! However, we will also be looking for BAD, and we can do that, very easily, with our already existing Criminal and Civil Justice System. For this purpose, I am forming the AI Force, much like I did Space Force, which has been a tremendous SUCCESS, in my First Term," he has repeatedly rejected pacing the development of frontier models, saying the U.S. has to maintain its edge over other countries, particularly China.
