Google Opens Gemini 4 Argon to Pro, Ultra, and Antigravity

Oct 13 rollout: Argon lands in the Gemini app and AI Mode in Search for Pro and Ultra, and inside Antigravity's desktop app and CLI for Ultra and eligible Enterprise plans — AI Pro users get the model in the app but not in the IDE.
Gemini API opens at $2/$10 per M tokens (cached input 95% off) through Nov 30, then rises to $4/$20; model ID is `gemini-4-argon` in AI Studio and the paid API tier.
Google-reported benchmarks: 77.9% on DeepSWE v1.1 (vs. 74.2% Opus 5.5 and 74.1% GPT-6 Astra) but only 57.4% on Terminal-Bench 4.0, behind Opus 5.5's 66.4%.
Google also offered six months of free top-tier Antigravity access to 10,000 scientists and researchers, and brought the Antigravity coding surface into the Gemini macOS app.

Oct 8: Apache-2.0 weights on Hugging Face; 12B total / ~2.5B active params in a mixture-of-experts, 131K context, trained purely with post-training RL on top of the Mellum 2 base.
SWE-bench Verified jumps from 2% (Mellum 2) to 47%, within three points of Qwen3.5-9B's 50%; LiveCodeBench v6 lands at 82% vs. Qwen's 75.4%.
JetBrains claims roughly 2x Qwen3.5-9B throughput on a single H200 under load — a vendor figure that hasn't been independently verified.
Positioned for self-hosted coding agents in IDEs; weights ship with a GGUF variant for Ollama/LM Studio.

heygen-com/hyperframes: 63.9k stars (+1,089 today) — Apache-2.0 framework that renders HTML/CSS/media and seekable animations to deterministic MP4 via headless Chrome + FFmpeg.
Ships 21 agent skills with `/hyperframes` as the router so Claude Code and other coding agents can author, preview, and render video from a single prompt.
Adapters for GSAP, Lottie, Three.js, Anime.js, CSS, and WAAPI; Node 22+ CLI covers preview, lint, and AWS Lambda rendering.
Pitched as a Remotion alternative; HeyGen says it's the same engine powering its own production videos, with tldraw and TanStack among listed adopters.

stablyai/orca: 92.7k stars (+919 today) — MIT desktop app for macOS/Windows/Linux that fans one prompt out to parallel Claude Code, Codex, OpenCode, and Pi agents, each in its own git worktree.
iOS/Android companion sends follow-ups and fires notifications when an agent finishes; a GPU-accelerated terminal keeps split panes and scrollback across restarts.
Design Mode lets you click any element in an embedded Chromium browser to feed its HTML, CSS, and a screenshot straight into an agent prompt.
SSH worktrees run agents on remote machines; GitHub and Linear integrations open worktrees directly from PRs, issues, and tasks.

anthropics/claude-plugins-official: 38.1k stars — curated directory users install from with `/plugin install {name}@claude-plugins-official`, split into first-party `/plugins` and vetted third-party `/external_plugins`.
Standardizes a plugin layout — `.claude-plugin/plugin.json`, optional `.mcp.json`, plus `commands/ agents/ skills/` subfolders — and locks plugin slug names at publish time so installs don't break on rename.
Puts Anthropic on the same marketplace footing as Cursor, which shipped its own plugin spec and marketplace repo two days ago; community indexes still carry an order of magnitude more plugins.
Repo stats show 199 open PRs and 1.1k issues, with Apache-2.0 licensing and skill-bundle support for repos that only ship SKILL.md files.
