Vercel said Hydrogen improves agentic coding, knowledge work and tool use, follows system instructions and task boundaries more closely, and offers stronger grounding that reduces unsupported claims in search-backed answers and invented tool or test results in coding reports. Developers call the model as `google/gemini-4-hydrogen` through AI Gateway, which Vercel says reflects provider pricing with no markup and no platform fee on inference, including Bring Your Own Key requests.", "body_md": "[Gemini 4 Hydrogen from Google](https://vercel.com/ai-gateway/models/gemini-4-hydrogen) is now available on AI Gateway.\n\nGemini 4 Hydrogen succeeds Gemini 3.8 Flash, improving agentic coding, knowledge work, and tool use while staying in the same latency class. It handles longer engineering tasks and produces better-researched documents, spreadsheets, and presentations in fewer agent steps.\n\nHydrogen follows system instructions, formatting requirements, and task boundaries more closely, with more reliable tool orchestration across long conversations. Improvements in visual reasoning and technical problem-solving support multimodal workflows, while stronger grounding reduces unsupported claims in search-backed answers and invented tool or test results in coding reports.\n\nUse `google/gemini-4-hydrogen` as the model name:\n\nTo use it in Claude Code, Codex, Cursor, and more, install the latest Vercel CLI and run setup:\n\nThen select `google/gemini-4-hydrogen` in the agent. See the [coding agents guide](https://vercel.com/docs/ai-gateway/coding-agents) for details.\n\nTry Gemini 4 Hydrogen in the [model playground](https://vercel.com/ai-gateway/models/gemini-4-hydrogen).\n\nAI Gateway provides a unified API for calling models, tracking usage and cost, and configuring retries, failover, and performance optimizations for higher-than-provider uptime. It includes built-in [custom reporting](https://vercel.com/changelog/custom-reporting-ai-gateway), [Zero Data Retention support](https://vercel.com/blog/zdr-on-ai-gateway), [budgets for API keys](https://vercel.com/docs/ai-gateway/authentication-and-byok/api-keys), [routing rules](https://vercel.com/docs/ai-gateway/models-and-providers/routing-rules), and more.\n\nAI Gateway reflects provider pricing with no markup and does not charge a platform fee on inference, including on [Bring Your Own Key](https://vercel.com/docs/ai-gateway/authentication-and-byok/byok) (BYOK) requests.\n\nYou can view [all language models](https://vercel.com/ai-gateway/models?type=text) available on AI Gateway.", "url": "https://wpnews.pro/news/gemini-4-hydrogen-now-available-on-ai-gateway", "canonical_source": "https://vercel.com/changelog/gemini-4-hydrogen-now-available-on-ai-gateway", "published_at": "2026-11-12 00:00:00+00:00", "updated_at": "2026-11-12 18:23:54.447803+00:00", "lang": "en", "topics": ["large-language-models", "ai-agents", "ai-tools", "developer-tools", "ai-products"], "entities": ["Vercel", "AI Gateway", "Google", "Gemini 4 Hydrogen", "Gemini 3.8 Flash", "Claude Code", "Codex", "Cursor"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/gemini-4-hydrogen-now-available-on-ai-gateway", "markdown": "https://wpnews.pro/news/gemini-4-hydrogen-now-available-on-ai-gateway.md", "text": "https://wpnews.pro/news/gemini-4-hydrogen-now-available-on-ai-gateway.txt", "jsonld": "https://wpnews.pro/news/gemini-4-hydrogen-now-available-on-ai-gateway.jsonld"}}
