OpenAI's Deployment Safety Hub published the ChatGPT Images 2.5 System Card alongside the product launch, Introducing ChatGPT Images 2.5, a new image generation model built to turn sketches, ideas, and reference photos into more polished, personalized outputs. Pairing the system card with the launch keeps the release inside OpenAI's standard preparedness and evaluation process.
On the developer and agent side, Google shipped two platform updates. ADK for Kotlin 1.0 brings the Agent Development Kit to Kotlin Multiplatform and Android, using zero reflection KSP tooling, giving mobile and backend developers a production path for building agents outside the existing Python and JS SDKs. Separately, Google Cloud introduced the Data Agent Kit, a set of MCP servers and agent skills for running data workflows from the IDE, available as an extension for VS Code forks (Antigravity IDE, Cursor) and as a plugin for Antigravity, Codex, and Claude Code.
OpenAI also highlighted agentic coding in production: 1Password says Codex lifted engineering productivity 21 percent, and an MIT researcher used GPT-5.6 Sol with Codex to run quantum computing experiments, including analyzing results and calibrating qubits autonomously.
On research and policy, OpenAI shared an AI-generated solution to the Navier-Stokes Millennium Prize Problem, including a formal proof in Lean, and announced $5 million in grants for independent research into AI and teen development, covering well-being and safety effects on younger users.
No new frontier model releases or API pricing or capability changes landed in this window; the notable items are the Images 2.5 launch with its accompanying system card and the Kotlin and Data Agent Kit tooling from Google.
