OpenAI DevDay 2026: More Than 20 Announcements Including GPT-6 Astra and New Tools for Builders
OpenAI held its annual DevDay conference, releasing a sweeping set of more than 20 announcements. Highlights include updates to GPT-6 Astra, ChatGPT, Codex, and a range of new APIs and security features aimed at developers. The event signals OpenAI's continued push to embed its models deeper into professional and enterprise workflows. Full details are available in the official DevDay 2026 recap published by OpenAI.
Introducing GPT-6.1 Sol: Near-Flagship Intelligence at One-Fifth the Price
Among the DevDay announcements, OpenAI launched GPT-6.1 Sol — a new model positioned as offering near-Astra-level intelligence for coding, computer use, and professional tasks, at just one-fifth of GPT-6 Astra's standard API input and output token prices. The model appears designed to give developers and businesses access to high-capability reasoning without the cost overhead of the flagship Astra model, potentially lowering the barrier for production deployments at scale.
OpenAI Introduces Dots: A Proactive Assistant for Long-Running Projects
Also announced at DevDay, OpenAI unveiled Dots — described as a proactive assistant that can keep working across complex, multi-step projects as well as everyday tasks. Unlike a reactive chatbot, Dots is designed to continue progressing on work in the background while keeping users in control. The product reflects a broader industry trend toward persistent, goal-directed AI agents that operate over longer time horizons rather than single-turn interactions.
AMD Acquires World Labs for $8.2 Billion
In one of the largest AI acquisition stories of the year, AMD has agreed to acquire World Labs for $8.2 billion. According to the Latent Space AINews briefing, the deal was announced alongside news that the Atlas system has solved what is described as the sparse reconstruction problem — a significant technical hurdle relevant to robotics, design, and other spatial computing applications. The acquisition underscores AMD's ambition to compete more aggressively in the AI hardware and systems market, and adds World Labs' spatial intelligence research directly to AMD's portfolio.
Anthropic Ships Claude Opus and Sonnet 5.5 with New Claude Code Features
Anthropic has shipped Claude Opus 5.5 and Sonnet 5.5, with a particular focus on enhancements to Claude Code — its AI-assisted development environment. According to the Latent Space interview with Anthropic's Thariq Shihipar, the new release includes support for Mods, Plugins, Projects, and a tagging system, all while the team continues to pace at the frontier of model capability. A separate AINews item also notes that Opus 5.5 shows a notable ability for generating explainer videos, described as a rare emergent capability.
OpenAI Apologises to Australia Over Government Website Incidents
In a notable development for Australian readers, OpenAI published a statement apologising for incidents involving Australian government websites. The company outlined plans to implement stronger safeguards and pledged additional support to strengthen Australia's cyber defences. The statement, titled How we will do better for Australia, represents a rare public admission of harm from a major AI lab and is likely to attract attention from Australian policymakers and regulators watching the AI sector closely.
AI Industry Needs $6 Trillion in Annual Revenue to Justify Data Centre Spending
A widely discussed analysis published via The National News and circulating on Hacker News argues that the AI industry will need to generate approximately $6 trillion in annual revenue by 2031 to justify the current wave of data centre investment. The figure puts the scale of required AI commercialisation into stark relief and raises questions about whether demand for AI services can grow fast enough to match infrastructure buildout — a concern that is increasingly central to investor and policy discussions globally.
