AI News Summary
Record-breaking funding and infrastructure deals dominated this cycle. An unnamed reinforcement learning startup raised a record $1.1B seed round targeting superintelligence, while Meta signed a major chip deal with AWS and Lightelligence surged 400% on its Hong Kong IPO debut, signaling investor conviction in optical interconnect as AI's next bottleneck.
Military and enterprise AI saw major moves:
- Google signed a classified AI deal with the Pentagon, joining OpenAI and xAI as military AI suppliers
- NVIDIA released Nemotron 3 Nano Omni, a long-context multimodal model for enterprise agents
- OpenAI open-sourced Privacy Filter, a lightweight PII redaction model under Apache 2.0
- GitHub shifted Copilot to usage-based billing, reflecting the true compute costs of agentic coding
The Musk v. Altman trial opened with dramatic testimony, with potential implications for OpenAI's corporate structure. Meanwhile, the FIDO Alliance, Google, and Mastercard began building authentication standards for AI agent commerce.
