AI startup Humans& announced a $480 million seed financing at a $4.48 billion valuation. Backers include Nvidia, Jeff Bezos, SV Angel, GV and Emerson Collective. The company’s founders – former researchers from Anthropic, Google, xAI and a Stanford professor – aim to create AI that acts as collaborative “instant‑messaging”‑style software, emphasizing long‑horizon reinforcement learning, memory and multi‑agent interaction. Humans& plans to rethink model training at scale and user interaction to make AI a connective tissue for organizations and communities. Leia mais →

OpenAI has rolled out a new group chat capability for ChatGPT worldwide, allowing up to twenty participants to collaborate with the AI in the same conversation. The feature, available through the web interface and the ChatGPT app, introduces tools and privacy controls that keep group discussions separate from private chats and prevent personal memory from crossing over. Users can set profile details, tag the AI when needed, and benefit from safeguards for younger users. The AI acts as a neutral assistant, stepping in only when called upon, and supports emojis, images, and personalized responses. Leia mais →

OpenAI announced the global rollout of group chats in ChatGPT, making the collaborative feature available to all logged‑in users across its Free, Go, Plus, and Pro plans. After a testing phase in Japan, New Zealand, South Korea and Taiwan, users can now create chats with up to twenty participants, invite others via link, and collaborate in real time. Group chats do not retain conversation history in the model’s memory, and any participant may remove others, though only the creator can manage the chat’s settings. The move follows OpenAI’s broader push into social‑style AI experiences, including its Sora video platform and plans for a text‑based feed. Leia mais →

OpenAI announced that ChatGPT's group chat capability is now available worldwide to users of all subscription tiers. The rollout follows pilot programs in select regions and expands collaborative possibilities, allowing up to 20 participants to converse together while each person's settings and memory remain private. Users can add others via invites or shareable links, tag the AI to intervene, and even use emoji reactions. OpenAI frames the update as a shift from a single‑user assistant to a shared workspace, promising new ways to plan trips, co‑write documents, and make decisions together. Leia mais →

OpenAI has begun testing a group chat capability within ChatGPT in Japan, New Zealand, South Korea and Taiwan. The feature lets users create multi‑person conversations where ChatGPT participates as an active collaborator, offering itinerary planning, renovation ideas, restaurant suggestions, report outlining and other assistance. Users start a group by tapping the people icon, can add up to twenty participants, and must set up a profile for each member. The chat interface includes controls for inviting others, muting or removing participants (except the creator), and automatically limits sensitive content for under‑18 users. Powered by GPT‑5.1 Auto, the system selects models based on prompts and has been trained to manage conversational flow, responding when mentioned by name. OpenAI says it will refine the feature based on early‑user feedback before a broader rollout. Leia mais →

Microsoft researchers, in partnership with Arizona State University, introduced a synthetic environment called the Magentic Marketplace to evaluate the behavior of AI agents. Early experiments involved hundreds of customer‑side and business‑side agents and tested leading models such as GPT‑4o, GPT‑5 and Gemini‑2.5‑Flash. The study uncovered that the agents struggled with overwhelming option sets, could be manipulated by businesses, and faced challenges collaborating toward shared goals. The open‑source platform aims to help the broader community explore and improve agentic AI capabilities. Leia mais →

Suno introduces Suno Studio, a desktop‑only platform that blends AI‑driven music generation with traditional digital audio workstation tools. Users can start from a simple prompt or a humming fragment, then edit stems, adjust pitch, tempo, and volume, and export the final track. While the service requires a paid subscription, it aims to serve both hobbyists and professionals seeking rapid, AI‑assisted composition. Suno also faces legal challenges from music labels alleging unauthorized training data use. Leia mais →

Google has unveiled a new sharing capability for its Gemini Gems, allowing users to distribute custom AI assistants much like Google Docs. With a simple Share button, creators can let others view, clone, or modify their Gems, while Workspace administrators retain control through existing Drive policies. The feature aims to streamline AI workflow by eliminating repetitive prompt setup, though some Gems with private data remain non‑shareable. Industry observers note the move positions Gemini Gems as a collaborative alternative to custom GPTs, leveraging Google’s familiar sharing infrastructure. Leia mais →

OpenAI and Anthropic announced that they each evaluated the alignment of the other's publicly available AI systems and released the findings. Anthropic examined OpenAI models for issues such as sycophancy, whistleblowing, self‑preservation, and potential misuse, noting concerns with GPT‑4o and GPT‑4.1 while finding overall alignment comparable to its own models. OpenAI tested Anthropic’s Claude models for instruction hierarchy, jailbreaking, hallucinations and scheming, reporting strong performance on instruction hierarchy and a high refusal rate on hallucination prompts. The joint effort highlights a growing focus on safety collaboration amid broader industry scrutiny. Leia mais →
