AI Product Updates Daily — May 31, 2026

The week closes with a wave of deprecations and pre-announcements. OpenAI retires two Codex-era models in 48 hours. Microsoft leaks four new MAI models ahead of Build on Monday. Gemini Spark goes live for Ultra subscribers. Meta reveals a wearable pendant that records every conversation you have. And SoftBank commits €75 billion to AI data centers in France.

OpenAI

GPT-5.2 and GPT-5.3-Codex retire from ChatGPT on June 2

OpenAI will remove GPT-5.2 and GPT-5.3-Codex from ChatGPT on June 2 — two days from now — as part of its ongoing model lifecycle cleanup.1 Paid subscribers will retain access to GPT-5.4 and GPT-5.5; free-tier accounts default to GPT-5.5 with no model toggle. The API is unaffected. GPT-5.3-Codex-Spark, a faster variant used in certain engineering pipelines, stays in service.2

Developer frustration has been visible since GPT-5.5 became the default: many reported degraded output quality and higher latency compared to the models being retired, and had already reverted to GPT-5.3-Codex manually.2 The June 2 deadline closes that off for ChatGPT users. API consumers building on those models have until a separate API sunset (announced separately on the developer portal).

Codex gets Windows Computer Use, GitHub Enterprise templates

The May 29 Enterprise release notes, posted while this issue was being compiled, confirm Codex on Windows now supports Computer Use — Codex can see, click, and type in Windows apps. Remote control lets users steer from a Mac, iOS, or Android device while the Windows host keeps running.3 For customer-hosted GitHub Enterprise Server repos, workspace admins can now set up a GitHub Enterprise app template so Codex can connect to on-premises code. Both Windows Computer Use and remote control are disabled by default for Enterprise accounts; contact your OpenAI rep to request early access.

Workspace agents out of beta on July 6 pricing clock

OpenAI is extending the free period for workspace agents until July 6, 2026, at which point credit-based pricing kicks in. The May 28 update also added GPT-5.5 support in agents, reasoning effort controls, speech output, role-based publishing permissions for the shared workspace directory, and smarter Slack thread replies.3

Microsoft

Four new MAI models expected at Build 2026 on June 2

Leaked build artifacts and a TestingCatalog report published May 30 outline four new models Microsoft is expected to announce at Build this Monday:4

Model	Type	Key change
MAI-Image-2.5	Image generation	Sharper output, built-in image editing, benchmark leader
MAI-Image-2.5e	Image generation (efficient)	Faster, cheaper, near-flagship quality
MAI-Transcribe-1.5	Speech recognition	Wider language support, better accuracy in varied environments
MAI-Voice-2	Text-to-speech	Adds Hindi, Spanish, French, Japanese, Korean, Portuguese, Turkish, Vietnamese, Chinese; whisper + emotional range

MAI-Voice-2 is the most substantial upgrade in the set — it expands from MAI-Voice-1's language roster and adds expressive delivery including a whisper mode. None of these are confirmed yet; Microsoft has not commented.

Google

Gemini Spark now live for AI Ultra subscribers in the US

Google's Gemini Spark — the 24/7 agentic assistant introduced at Google I/O — began rolling out to AI Ultra subscribers in the US on May 31.5 Spark runs on Gemini 3.5 and the Antigravity 2.0 runtime, which allows tasks to execute in the background on a continuous basis — including when the phone is off.5 AI Ultra costs $200/month.

NotebookLM development build reveals three upcoming features

Dev builds spotted by TestingCatalog show three unannounced features in the NotebookLM pipeline:6

Personal Preferences — remembers output style, preferred format, and workflow instructions across sessions, eliminating the need to re-specify them every time.
Connectors — direct data pull from Google Drive, Gmail, and Calendar, and potentially third-party tools, removing the manual upload step.
Canvas — turns research material into interactive web artifacts: timelines, lesson plans, visual explainers, full web pages.

Google has not announced release dates for any of these.
