1. Moonshot’s Kimi K2.5 open-weights model on par with GPT-5.2, Opus 4.5, Gemini 3 Pro

Across major benchmarks, according to Moonshot:

  • The model is live on Kimi.com in chat and agent modes.

  • K2.5 Agent Swarm is available in beta for high-tier users.

  • Weights are available through Hugging Face.

  • Chinese AI company.

  • DeepSeek has been teasing its next major release in recent weeks but without specifics.

2. OpenAI said to target ~$60 CPM for ChatGPT ads in early premium push

  • OpenAI reportedly won’t initially provide detailed data on ad context or user conversions.

  • Early advertisers will get basic metrics such as impressions and total clicks.

  • High-level insights like total ad views will be provided, an OpenAI spokesperson confirmed.

  • OpenAI’s partnership team has already made some early ad sales, including with existing enterprise customers.

  • Many advertisers are likely to hold off on major spend until there’s evidence ads drive sales.

  • We provide human cryopreservation, using extremely low temperatures to stop biological processes in the body. Patients are cryopreserved in the expectation that future technology may be able to revive them and treat their underlying cause of death.

  • We’ve improved all aspects of human cryopreservation, including patient storage, by building a secure long-term facility in Switzerland where patients are stored indefinitely until revival may one day be possible.

  • Membership includes cost savings on cryopreservation costs and access to our community and resources. Use code BAY10 for 10% off when you’re ready. Start by learning how cryopreservation actually works on our site.
