GPT-5.6 Sol Ultrafast; ChatGPT Adds Computer History
OpenAI announced an “Ultrafast” performance tier for GPT‑5.6 Sol that can generate up to 750 output tokens per second and deliver up to 14× faster throughput than standard processing, enabled in part by Cerebras wafer‑scale hardware. It also introduced Computer History, an opt‑in feature in the ChatGPT and Codex desktop app for Mac that builds a local timeline of recent interactions (clicks, keystrokes, inputs, app switches and shortcuts) to help resume tasks and surface recurring workflows; it excludes screenshots, screen recordings, microphone input, system audio and private browsing. Interaction events are stored temporarily on the Mac, briefly processed in a short‑lived Codex session on OpenAI servers and deleted (temporary files removed within 48 hours); Memory files remain local until the user deletes them. Computer History is rolling out first to Pro, Business and Enterprise Mac users (admins may need to enable workspace access) but is initially unavailable in Germany, the EEA, the UK and Switzerland.
A major AI platform (OpenAI) announced a low-latency tier for a foundational model and a new client-side context feature; both affect real-time conversational use cases, customer support, e-commerce interactions and developer workflows relevant to AdTech/MarTech applications.

Recent verified developments and strategic activity across this market segment.
ChatGPT 'Computer History' Records Mac Activity
OpenAI has deployed a Mac-only ChatGPT feature called "Computer History" that can record user activity on macOS by using accessibility APIs. The feature is currently available to Pro subscribers (~€100) and to Business/Enterprise customers if enabled by admins; it was initially unavailable in the EU but is now active there. Computer History logs keyboard and mouse usage, can request screenshots, and writes detailed Markdown "memory" files into the user directory (.codex/memories/...), which OpenAI says are not deleted. An internal cache holds additional data for at least two days. Users can exclude apps or websites and control whether collected data is used for model training via the account training toggle. The implementation raises significant data protection and security concerns because memory files are stored in plain user-accessible locations and may expose sensitive content such as visited URLs and 2FA codes.
OpenAI launches GPT‑5.6 family, ChatGPT Work
OpenAI released the GPT‑5.6 family and on the same day consolidated its product lineup into a single desktop app that combines chat, a long-running agent (ChatGPT Work), and coding views. Standalone Codex was retired and the Atlas browser is being phased out as OpenAI folds agentic and coding capabilities into one console that can access local files and drive desktop workflows. The newsletter also reports related industry moves: Meta’s Mark Zuckerberg promoted Muse Spark 1.1 on X to launch Meta’s agentic coding model, Google rolled out a buried “created or edited with AI” disclosure for ads across Search, Discover and YouTube, and market notes flagged quant funds’ recent losses tied to AI chip trades. The piece frames these as signs of platform consolidation and shifting distribution dynamics for AI models and tools.
OpenAI launches Ultrafast mode for GPT-5.6 Sol
OpenAI has introduced Ultrafast, a new preview mode that accelerates its GPT-5.6 Sol model to operate at roughly 14x the speed of standard processing. The company says Ultrafast can generate up to 750 output tokens per second and is intended for real-time enterprise workflows such as incident response, customer support, financial market analysis, and e-commerce. The preview is initially available to a limited group of customers and will expand as capacity grows. OpenAI is powering Ultrafast through a partnership with chipmaker Cerebras. Competitors such as Anthropic have offered fast modes for their models, but OpenAI positions Ultrafast as delivering materially higher throughput in this release.
