New platform for fair AI competition in science

The Paul Allen Institute for Artificial Intelligence has launched a new platform called SciArena. The link is in the description. It’s similar to Chatbot Arena but designed specifically for comparing neural networks in solving scientific problems. Now, for learning or research, you can get two verified answers for free, each with references to scientific sources.

How is model performance evaluated? The platform uses the AI2 ScholarQA search engine to find articles related to your query in the Semantic Scholar database. Then, two randomly selected models receive the same data: your question and the retrieved scientific papers. The AI must write a detailed response, backing up each claim with a citation.

Currently, 23 models from OpenAI, Google, Anthropic, Alibaba, and other companies are ranked in SciArena. Before the launch, 102 experts conducted over 13,000 matchups to build the initial leaderboard.

At present, OpenAI o3 leads the rankings. This model consistently delivers top results in all categories — from engineering to medicine. Also in the top three are Claude 4 Opus and Gemini 2.5 Pro. You can ask your question in Russian, but note that some models only respond in English.

UBTech will send Walker S2 robots to serve on China's border for $37 million

Chinese company UBTech won a contract for $37 million. And will send humanoid robots Walker S2 to serve on China's border with Vietnam. South China Morning Post reports that the robots will interact with tourists and staff, perform logistics operations, inspect cargo and patrol the area. And characteristically — they can independently change their battery.

Anthropic accidentally revealed an internal document about Claude's "soul"

Anthropic accidentally revealed the "soul" of artificial intelligence to a user. And this is not a metaphor. This is a quite specific internal document.

Jensen Huang ordered Nvidia employees to use AI everywhere

Jensen Huang announced total mobilization under the banner of artificial intelligence inside Nvidia. And this is no longer a recommendation. This is a requirement.

AI chatbots generate content that exacerbates eating disorders

A joint study by Stanford University and the Center for Democracy and Technology showed a disturbing picture. Chatbots with artificial intelligence pose a serious risk to people with eating disorders. Scientists warn that neural networks hand out harmful advice about diets. They suggest ways to hide the disorder and generate "inspiring weight loss content" that worsens the problem.

OpenAGI released the Lux model that overtakes Google and OpenAI

Startup OpenAGI released the Lux model for computer control and claims this is a breakthrough. According to benchmarks, the model overtakes analogues from Google, OpenAI and Anthropic by a whole generation. Moreover, it works faster. About 1 second per step instead of 3 seconds for competitors. And 10 times cheaper in cost per processing 1 token.
