Antigravity 2.16 reads Word, Excel, PowerPoint straight into prompts
Google's agentic IDE now feeds Office files to Gemini natively, cards every subagent live, and sandboxes on Windows — plus two 1M-context models hit OpenRouter.
Copy markdown
Office docs go straight into the agent
Drag a .docx, .xlsx, or .pptx into a prompt and Gemini reads it natively instead of opening the stored file — point an agent at a spreadsheet or slide deck without converting it to text first. Shipped in 2.16.0.
Every subagent gets a live status card
Subagent invocations now render as dedicated cards in the conversation stream with running, waiting, and completed states, so a multi-agent run is legible at a glance instead of a scrolling wall of text.
File and network sandboxing lands on Windows
Version 2.15.1 brought file and network sandboxing to Windows, matching the isolation Mac and Linux already had — the agent can act without free rein over your machine. 2.16 also adds one-click connect to a WSL distro.
Startup scan drops from a minute to under a second
Discovering skills and customizations on large or network-mounted projects now completes in under a second, down from over a minute — real time back on every cold start.
Elsewhere: two 1M-context models hit OpenRouter
Z.ai's GLM 5.3 Prime ($2.80/$8.80 per M) and Qwen's Qwen3.8 Max Prime ($4/$12 per M) both landed Sep 23 with 1M-token context — two more frontier-priced long-context options to route agents to.
Elsewhere: LLM 0.36 adds GPT-6 and cleaner logs
Simon Willison's LLM CLI now speaks to gpt-6-sol and gpt-6-luna, lets plugins flag single-turn-only models, and wraps reasoning traces in collapsible details blocks in llm logs output.
