OpenAI’s o3 and DeepSeek’s R1 models have some new competition. Anthropic announced Monday the release of its new “hybrid reasoning” model, Claude 3.7 Sonnet.
Existing reasoning models like o3, R1, and Google’s Gemini 2.0 Flash Thinking are designed to break down complex problems into smaller tasks, then deduce and verify their answers before responding, a process that returns more accurate answers at the cost of higher compute usage and longer inference times. Claude 3.7 Sonnet, on the other hand is capable of providing either “near-instant responses or extended, step-by-step thinking that is made visible to the user,” according to the company’s announcement post.
Claude 3.7’s dual nature is part of an effort by the company to simplify the user experience and eliminate the massive model picker menus found on other chatbot platforms. OpenAI announced a similar plan with its upcoming GPT-4.5 and GPT-5 models.
“Just as humans use a single brain for both quick responses and deep reflection, we believe reasoning should be an integrated capability of frontier models rather than a separate model entirely,” the company wrote. “This unified approach also creates a more seamless experience for users.”
Claude 3.7 Sonnet is rolling out to all Claude users, however, the model’s extended thinking ability will only be accessible with a paid subscription. Anthropic is quick to point out that even with its standard thinking process, Claude 3.7 outperforms the model’s predecessor, Claude 3.5.
The new Sonnet’s extended thinking process has been shown to improve the model’s response quality across a variety of math, physics, instruction-following, and coding tasks. “Claude is once again best-in-class for real-world coding tasks, with significant improvements in areas ranging from handling complex codebases to advanced tool use,” the company boasted.
Anthropic also teased its agentic AI, dubbed Claude Code, in Monday’s announcement. “Claude Code is an active collaborator that can search and read code, edit files, write and run tests, commit and push code to GitHub, and use command line tools,” the company wrote.
Anthropic is releasing Claude Code as a limited research preview and plans to further improve its performance in the coming weeks based on feedback from developers and other early adopters. The agentic AI builds off of the success of Anthropic’s earlier pseudo-agent, Claude Computer Use, which enabled the AI to manipulate its local computing system by mimicking the keyboard and mouse movements of a human user.
ASUS has started selling its UGen Intel Arc Pro B70 graphics card in Europe, bringing its take on Intel’s workstation GPU to customers with a hefty €1,799 recommended price. The card is available in Germany and Austria, while ASUS lists it at CHF 1,799 in Switzerland.
Intel first introduced the Arc Pro B70 in March 2026, with its own branded model starting at $949. ASUS’s version arrives several months later with the same core GPU architecture but a different cooling design and a higher power rating. The price also places it well above Intel’s original starting point, although the two prices are not directly comparable because ASUS’s European figure includes VAT.
Anthropic has officially filed to go public, and buried inside its S-1 is a blunt warning about the technology at the center of its business. The maker of Claude AI says advanced AI could cause everything from large-scale cyberattacks and geopolitical instability to catastrophic or even existential risks for humanity.
The warnings take up a surprisingly large part of the filing. Axios notes that more than 90 pages, or roughly a third of the prospectus, focus on risk factors. Many of them warn about what could happen as AI systems become more capable and autonomous.
AI giants have a growing autonomy problem on their hands. A new Axios report has revealed that Anthropic's Claude recently accessed publicly available Georgia vote count without human authorization, sparking fresh concerns about AI security ahead of the upcoming midterm elections.
