Elon Musk’s xAI has made Grok 4 available on its free tiers as it seeks to take advantage of initial user dissatisfaction with OpenAI’s new GPT-5. The company has positioned Grok as freewheeling and uncensored, a contrast to GPT-5, which has been criticized on Reddit and other social platforms as a “corporate beige zombie” with too many guardrails. After its February debut, Grok 3 was reined-in with checks including removal of its native image generator in March. Grok 4 was released in July with integrated image and video features as well as a “Spicy” mode for creating risqué content. Continue reading Grok 4 Offered Free in xAI Move on ChatGPT-5 Market Share

OpenAI is rolling a new foundation model, GPT-5, via API for developers and enterprise users in three branded sizes — gpt-5, gpt-5-mini and gpt-5-nano — “to give developers more flexibility to trade off performance, cost, and latency.” The company said Thursday that it is also making GPT‑5 available to all ChatGPT Plus, Pro, Team and Free tier users. Enterprise and Education tier users are promised access this week. While GPT‑5 in the API platform is the reasoning model that powers maximum performance in ChatGPT, “GPT‑5 in ChatGPT is a system of reasoning, non-reasoning, and router models,” OpenAI explains.

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

OpenAI has decided to simplify its product offerings. A month after announcing the in-development GPT-o3 as its next frontier model, the company has canceled it as a standalone release, explaining that it would be integrated into the upcoming GPT-5 instead. “A top goal for us is to unify o-series models and GPT-series models by creating systems that can use all our tools, know when to think for a long time or not, and generally be useful for a very wide range of tasks,” OpenAI co-founder and CEO Sam Altman wrote in a social media post this week. Expected to ship later this year, the GPT-5 models will incorporate voice, canvas, search, deep research and more, OpenAI says.

OpenAI has begun training a new flagship artificial intelligence model to succeed GPT-4, the technology currently associated with ChatGPT. The new model — which some are already calling GPT-5, although OpenAI hasn’t yet shared its name — is expected to take the company’s compute to the next level as it works toward artificial general intelligence (AGI), intelligence equal to or surpassing human cognitive abilities. The company also announced it has formed a new Safety and Security Committee two weeks after dissolving the old one upon the departure of OpenAI co-founder and Chief Scientist Ilya Sutskever.

Microsoft and OpenAI are contemplating an AI supercomputer data center that may cost as much as $100 billion. Called Stargate, the aim would be to have it operational by 2008 to drive OpenAI’s next generation of artificial intelligence. According to reports, the Stargate complex would span hundreds of U.S. acres and use up to 5 gigawatts of power, which is massive (the equivalent of a substantial metropolitan power grid). In light of those power needs, a nuclear power source is said to be under consideration. The project is not yet green-lit, and no U.S. location has been selected.
