Hydrogen costs 25% less than Gemini Carbon and Argon today and 75% less after those models' December 1 price doubling, though it remains 15x the input price of Haiku 5.5. The release sits above Argon on the AA index.", "body_md": "Hydrogen replaces Gemini 3.8 Flash and lifts Terminal-Bench 4.1 from 18.2% to 57%, and it is now the free-tier model.

Many US startups build on Chinese open models trained on Blackwell GPUs, so tighter rules reach that supply.\nRead: Fable 5.2 also spends less per attempt than GPT-6 Astra, $105 against $235, for ten more points. Across 624 trajectories, most failures came from agents testing on easier inputs than the hidden cases, then shipping work that broke at real scale.\nTry: Plugins can now declare a Claude Code version range in plugin.json, and clients outside it skip them, so a plugin update no longer breaks older installs. Long hooks in claude -p and SDK sessions send a 30-second heartbeat, so hosts stop ending those turns as hung.\nTry: Any app that validates client UI messages was exposed: a small request with many malformed parts made validation report every schema for every part. The release also keeps Azure and Vertex credentials from reaching third-party file hosts during downloads.\nRead: Request logs only show that a call succeeded, so an agent that orders a hot latte for an iced request looks healthy. Grading repeated end-to-end runs measures how often the task is done right, which a single manual test cannot show because outputs vary.", "url": "https://wpnews.pro/news/google-ships-gemini-4-hydrogen-at-1-50-7-50-above-argon-on-aa-index", "canonical_source": "https://www.vibeleaderboard.ai/intel/brief/2026-11-13", "published_at": "2026-11-13 12:11:13+00:00", "updated_at": "2026-11-13 12:24:46.535555+00:00", "lang": "en", "topics": ["large-language-models", "artificial-intelligence", "ai-products", "generative-ai"], "entities": ["Google", "Gemini 4 Hydrogen", "Gemini 3.8 Flash", "Gemini Carbon", "Gemini Argon", "Haiku 5.5", "Terminal-Bench 4.1", "AA index"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/google-ships-gemini-4-hydrogen-at-1-50-7-50-above-argon-on-aa-index", "markdown": "https://wpnews.pro/news/google-ships-gemini-4-hydrogen-at-1-50-7-50-above-argon-on-aa-index.md", "text": "https://wpnews.pro/news/google-ships-gemini-4-hydrogen-at-1-50-7-50-above-argon-on-aa-index.txt", "jsonld": "https://wpnews.pro/news/google-ships-gemini-4-hydrogen-at-1-50-7-50-above-argon-on-aa-index.jsonld"}}
