OpenAI and Anthropic — rivals in the AI space who guard their proprietary systems — joined forces for a misalignment evaluation, safety testing each other’s models to identify when and how they fall short of human values. Among the findings: reasoning models including Anthropic’s Claude Opus 4 and Sonnet 4, and OpenAI’s o3 and o4-mini resist jailbreaks, while conversational models like GPT-4.1 were susceptible to prompts or techniques intended to bypass safety protocols. Although the test results were unveiled as users complain chatbots have become overly sycophantic, the tests were “primarily interested in understanding model propensities for harmful action,” per OpenAI.

This week, DeepSeek-V3.1 dropped on Hugging Face. Media outlets immediately began citing benchmark scores that rival proprietary systems from OpenAI and Anthropic for a system that is available via a permissive license, facilitating wide access. The 685-billion parameter Mixture-of-Experts (MoE) model has 37 billion active parameters and is designed for efficiency. It builds on DeepSeek-pioneered processes like multi-head latent attention (MLA) and multi-token prediction (MTP) to optimize inference, enabling high-performance computing on both enterprise servers loaded with H100 GPUs and consumer hardware like a Mac Studio or comparably powered PC.

Claude Opus 4 and 4.1 now have the discrete ability to end “abusive” or “harmful” conversations in consumer chat interfaces. Anthropic says the feature was developed as part of its exploratory work on the protection and well-being of its AI models. The company also envisions broader safety uses, although it does point out that having a model defensively terminate a chat is an extreme measure, intended for use in rare cases. “We’re working to identify and implement low-cost interventions to mitigate risks to model welfare,” Anthropic explains, qualifying it is unsure “such welfare is possible.” Continue reading New Anthropic Safety Updates Focus on Claude’s Well-Being

Anthropic has released Claude Opus 4.1, an upgrade to Opus 4 that reportedly improves on agentic tasks, computer coding and reasoning. Pricing has not increased from what customers were paying for Opus 4, and the company promises “substantially larger improvements to our models in the coming weeks.” The move comes as Anthropic nears a new funding round targeting $3 to $5 billion, which could place a valuation of up to $170 billion on the startup. Recurring revenue hit $5 billion as of late July, which could increase to $9 billion by the end of the year. Claude Opus 4.1 was released two days before OpenAI unleashed GPT-5, and performs comparably in coding benchmarks. Continue reading Anthropic Seeks to Raise $5 Billion, Debuts Claude Opus 4.1

Anthropic’s new mobile conversation voice mode for its large language model Claude lets it search Google Docs, Drive, Calendar and more on smartphones. Just a week after debuting two new LLMs — Claude Opus 4 and Sonnet 4 — Anthropic announced the mobile updates for its Claude AI chatbot for iOS and Android and said it is extending web search for all users on free Claude plans. While Claude’s conversational voice interface is currently available only in English and only via mobile, an API for desktop use and browser-based support are part of future plans. Amazon and Google both have investment stakes in San Francisco-based Anthropic. Continue reading Anthropic Touts Mobile Voice Mode, Free Search for Claude
