OpenAI launches the GPT-5.6 family and ChatGPT Work

(5 newsletters)

OpenAI released its GPT-5.6 model family in three tiers: Sol (the flagship), Terra (a cheaper everyday option), and Luna (the fastest and most affordable), with pricing that matches GPT-5.5 and a new “Ultra” mode that coordinates multiple agents across parallel workstreams. Reviewers peg Sol as landing just below Fable on the Intelligence Index but ahead on agentic coding, at a much lower price. Alongside the models, OpenAI shipped ChatGPT Work, a Codex-powered agent aimed at non-technical everyday tasks, and folded the Codex app into a revamped ChatGPT desktop app with a built-in browser and computer control. It is a direct answer to Anthropic’s Claude Cowork.

OpenAI’s GPT-Live makes ChatGPT Voice feel human

(6 newsletters)

OpenAI launched GPT-Live, a full-duplex voice model that can listen and speak at the same time, handle interruptions and pauses, and keep a conversation flowing while heavier reasoning is handed off to GPT-5.5 in the background. It now powers ChatGPT Voice globally, with GPT-Live-1 for paid users and a mini version for free users, plus live translation. OpenAI is also bringing GPT-Live-1 and the mini model to the API, positioning voice as infrastructure developers can build on rather than just a ChatGPT feature.

SpaceXAI and Cursor ship Grok 4.5

(4 newsletters)

SpaceXAI, the rebranded xAI, released Grok 4.5 as its strongest model yet and its first since acquiring coding startup Cursor, with the model co-trained alongside Cursor for coding and agentic work. Elon Musk called it “Opus-class,” and internal benchmarks show it beating Claude Opus 4.8 on several coding tests while finishing tasks in fewer steps at a fraction of the cost. It is now the default model for Grok Build, is available to all Cursor users, and plugs into Word, PowerPoint, and Excel.

Meta debuts Muse Image and puts Muse Spark 1.1 behind a paid API

(6 newsletters)

Meta’s Superintelligence Labs launched Muse Image, its first AI image model, now powering tools in the Meta AI app, Instagram, and WhatsApp, with an “agentic” approach that reasons through prompts and lets users pull tagged Instagram accounts’ public photos into generated images. Separately, Meta released Muse Spark 1.1 for agentic tasks and computer use and, for the first time, put it behind a paid developer API priced at roughly a quarter of top rivals. Zuckerberg promised “aggressive” pricing and called the model state of the art or close to it on agentic reasoning.

Claude Cowork comes to mobile and web

(3 newsletters)

Anthropic expanded Claude Cowork, its general knowledge-work agent, from desktop to web and mobile, starting in beta for Max subscribers. A Dispatch feature keeps a persistent thread running so tasks continue even with the laptop closed. Anthropic’s analysis of 1.2M sessions found the tool is used mostly for “the work around the work,” with business operations at 33 percent of usage and content creation at 16 percent, and comparatively little coding.

OpenAI retracts its SWE-Bench Pro endorsement after audit finds a third of tasks broken

(3 newsletters)

An audit of the widely used SWE-Bench Pro coding benchmark found that roughly 30 percent of its public tasks are broken due to overly strict tests, underspecified prompts, and misleading instructions. The review combined automated screening with human software-engineer review, and led to a retracted recommendation to move to the benchmark. It is a reminder that flawed evaluations can distort how model progress, safety, and coding ability are judged.
