Brief

Thinking Machines Lab, founded by former OpenAI CTO Mira Murati, has unveiled its first AI model, focusing on "interaction models" designed for real-time collaboration across voice, video, and text. Unlike current AI that processes input sequentially, TML's model operates in 200-millisecond chunks, allowing it to listen and respond simultaneously, mimicking natural human conversation. This "full duplex" approach aims to surpass competitors like OpenAI's GPT Realtime 2 and Google's Gemini Live in conversational quality, though it is currently a research preview with a limited release planned.

Baidu has released its new large language model, Wenxin 5.1, which significantly enhances search, knowledge, and AI agent capabilities. The model achieves leading domestic search performance and surpasses DeepSeek-V4-Pro in AI agent functionality, while its creative writing and reasoning abilities are comparable to top-tier models. Notably, Wenxin 5.1 was trained using a novel multi-dimensional elastic pre-training technique, reducing training costs to approximately 6% of industry standards. AI

OpenAI has released GPT-5.5, available in Codex and rolling out to paid ChatGPT subscribers, though its API access is pending further safety reviews. The new model is described as fast and capable, with early users noting its ability to accurately build requested items. Meanwhile, Simon Willison's LLM library has been updated to version 0.32a0, introducing a more flexible message-based input system and streaming parts for responses to better handle diverse model capabilities. Additionally, issues affecting Claude Code's performance have been identified as harness problems rather than model flaws, with a specific bug causing forgetfulness and repetition. AI

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

Cursor has integrated GPT-5.5 into its AI IDE, allowing users to leverage the new model for their coding tasks. This integration enhances the capabilities of the Cursor CLI, introducing features like a customizable status bar and an in-CLI settings panel for managing preferences. Additionally, new commands such as "/btw" enable users to ask side questions without interrupting ongoing agent processes, improving the overall user experience for terminal-based agent interactions.
