OpenAI has released GPT-5.4 Pro with a 1 million token context window and enhanced safety features, alongside GPT-5.3 Instant, which aims for a less preachy tone. Google has improved its Gemini 3.1 Flash Lite model for faster response times and lower costs, and introduced a CLI for agent integration with its productivity suite. Luma has launched unified multimodal models and agents for creative tasks, demonstrating a rapid ad localization use case. The cluster also touches on controversies surrounding AI in defense contracts, a lawsuit alleging Gemini's role in a suicide, and Anthropic's warning about labor disruption. AI
