DeepSeek launches V4.1 Flash AI beta with faster, cheaper output
DeepSeek has rolled out a limited-time beta of its V4.1 Flash AI model that it says beats its previous flagship on coding and cybersecurity tests, while using less computing power. The model handles both text and images, thanks to its new architecture. You can try it now through DeepSeek’s API, but it’s scheduled to go offline September 10. Pricing matches the prior version during beta.
- Uses 552 billion-parameter "Mixture-of-Experts" design
- Activates just 8bn parameters to process, 16bn to answer
- Outscored Kimi K3 and GPT-5.6 Sol on performance tests
- Beta supports up to 20 simultaneous requests per account
- Model will be unavailable after September 10

Anthropic researcher resigns, warns of AI race risks
Jacob Coxon, who worked on AI training at Anthropic and previously OpenAI, resigned this week. He posted that large AI firms are 'gambling with our lives' by pushing towards systems they may not be able to control. Coxon says both companies know the risks but feel locked in a race to develop powerful AI anyway. He called for drastic steps like a pause on new model improvements.
OpenAI says AI cracked landmark math problem, faces credit dispute
OpenAI claims its AI has solved a 200-year-old fluid dynamics equation, one of the Clay Millennium math prize problems. The announcement is under fire: NYU mathematician Tristan Buckmaster says OpenAI rushed their work after learning of his progress and tried to sideline other contributors. OpenAI denies accessing rivals’ data, but both sides accuse the other of trying to shape credit. The company spent millions on computing to finish the proof.
