Model Card
Gemini 4 Hydrogen is a multimodal reasoning model from Google DeepMind, released on November 12, 2026 as part of the Gemini 4 family alongside Gemini 4 Argon and Gemini 4 Carbon. Google describes it as an everyday model for coding and agentic workflows and positions it as the successor to Gemini 3.8 Flash.
It accepts text, images, audio, video, and files, returns text, and supports tool calling and four thinking levels (low, medium, high, and xhigh) across a 1M-token context window.
Google reports 57% on Terminal-Bench 4.1, up from 18.2% for Gemini 3.8 Flash, with tasks finishing 2.5x faster than 3.8 Flash. On the Artificial Analysis Intelligence Index it scores 51 at high thinking, one point above Gemini 4 Argon.
It suits code fixes and debugging, multi-step agents, data analysis, and reports built from PDFs, spreadsheets, audio, and video.

Gemini 4 Carbon
Gemini 4 Carbon is Google DeepMind's top model in the Gemini 4 family, announced on October 28, 2026 as a step above Gemini 4 Argon. Google built it for long, multi-step software engineering and defensive cybersecurity, such as finding, validating, and patching vulnerabilities. Google reports 88.2% on SEC-bench Pro, 54.8% on ExploitGym, and 71.0% on CWE-bench. It scores 59 on the Artificial Analysis Intelligence Index v5.0, which Google says places it first on that index. It accepts text, image, audio, video, and file input with a 1M-token context window. Google listed launch pricing of $2 per million input tokens and $10 per million output tokens, rising to $4 and $20 later, with cached input 95% cheaper. On Puter it currently costs $1.60 per million input tokens and $8 per million output tokens. It suits coding agents, security tooling, and long-document analysis.
ChatGemini 4 Argon
Gemini 4 Argon is Google's flagship Gemini 4 model, announced by Google DeepMind on September 30, 2026. It is aimed at long, multi-step software engineering, legal and finance work, and defensive cybersecurity. Google reports 77.9% on DeepSWE v1.1 (Claude Opus 5.5 74.2%, GPT-6 Astra 74.1%) and 19.6% on Harvey's Legal Agent Benchmark. It trails Opus 5.5 on Terminal-bench 4.0 (57.4% vs 66.4%) and GPT-6 Astra on FrontierSWE v2 (55.0% vs 65.5%). Vals.ai places it first on the Vals Index at 68.9%. Introductory pricing is $2 per million input tokens and $10 per million output tokens, rising to $4 and $20 later. It suits teams running coding agents or document-heavy professional workflows.
ImageGemini Nano Banana 2.1
Gemini Nano Banana 2.1 is Google's image generation and conversational editing model, released in October 2026 as an update to Nano Banana 2 (Gemini 3.1 Flash Image). It keeps Flash-tier speed and cost while improving visual quality, prompt adherence, text rendering, and multi-turn character consistency. It accepts text, image, video, and PDF input and returns images and text. Output is available at 1K, 2K, and 4K, with fixes for tiling artifacts on wide aspect ratios such as 1:8 and 8:1 at 2K and 4K. It can combine up to 14 reference images, and supports search grounding and configurable thinking levels. A 1K image costs $0.0336. Choose it for infographics, text-heavy graphics, and multi-step editing where the same characters must stay consistent across turns.
