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.

OpenAI has significantly improved its image generation capabilities with "Images 2.0," making AI-generated visuals increasingly indistinguishable from real ones. Separately, a new version of ChatGPT, referred to as "ChatGPT 5.5 Pro," has demonstrated the ability to perform complex, doctoral-level mathematical research in just one hour, prompting mathematicians to note a potential shift in the baseline for human research. Meanwhile, Anthropic is reportedly planning to establish an "AI McKinsey" with a $1.5 billion investment, aiming to leverage AI for strategic consulting. AI

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 three new real-time voice models: GPT-Realtime-2, GPT-Realtime-Translate, and GPT-Realtime-Whisper. These models offer enhanced reasoning capabilities, live speech translation for over 70 languages, and low-latency transcription. GPT-Realtime-2, in particular, is described as having "GPT-5-class reasoning" and features a significantly expanded context window of 128K tokens, alongside improved handling of interruptions and tool usage.

OpenAI has released GPT-5.5, which offers improvements in factuality, intelligence, and image understanding, and is now the default model for ChatGPT and its API. This release also enhances personalization, allowing ChatGPT to utilize user memories, past chats, and connected files. Additionally, OpenAI has introduced an Agents SDK for TypeScript and updated its Codex model to function as a general-purpose computer work agent, expanding its capabilities beyond coding. 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 launched its new GPT-5.5 model, reporting rapid API revenue growth and increased demand for its coding tools. The release is accompanied by a peculiar system prompt directive for Codex to "never talk about goblins." Meanwhile, OpenAI President Greg Brockman testified in the ongoing trial against Elon Musk, disclosing his significant equity stake in the company and defending his financial interests and contributions.

Google DeepMind has released Gemma 4, a new family of open-weight models licensed under Apache 2.0, marking a significant advancement in their open-source AI offerings. The models are designed for reasoning and agentic workflows, with versions optimized for local and edge deployment, including native multimodal capabilities for text, vision, and audio. Early benchmarks suggest competitive performance, with the 31B model ranking highly among open-source options, and rapid ecosystem support has emerged from various platforms like llama.cpp and Ollama. 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. AI

Anthropic has withheld its new Claude Mythos model from public release due to its advanced capabilities in finding and exploiting software vulnerabilities. The company is instead providing access to select cybersecurity firms through Project Glasswing to help patch critical software before the model's capabilities become more widely available. This decision highlights a shift from previous AI releases, where caution stemmed from unknown risks, to a current scenario where known, potent risks necessitate controlled access. AI
