Gemini 4 Argon: announced 2026-09-30. Google states only the output limit — 1M tokens (up from 64K) — and has not published an input context window (third-party reports of 2M tokens can't be traced to a Google source); introductory pricing is $2.00 input / $10.00 output per 1M tokens, doubling to $4.00 / $20.00 once the promo ends; it sets a new SOTA on DeepSWE v1.1 at 77.9% (vs. 74.2% for Opus 5.5 and 74.1% for GPT-6 Astra), but only scores 55% on FrontierSWE v2, trailing GPT-6 Astra's 65.5%; access is currently limited to trusted security partners through the Fairwind Program — developers, enterprises, and consumers don't have it yet
Gemini Omni 1.1 Flash (gemini-omni-1.1-flash): GA since 2026-08-27, replacing the preview that launched 6/30; closed-source, priced per output second: $0.03 at 360p, $0.10 at 720p (default), $0.15 at 1080p, $0.30 at 4K (1080p/4K are upscaled); ranks #1 on the Artificial Analysis Text-to-Video Arena without audio (1322 Elo) and #2 with audio (1237, trailing Wan3.0's 1241); adds scene extension (10s of context, chainable up to 40s total) and first/last-frame interpolation for camera control
Gemini is Google DeepMind's native multimodal LLM family, famed for a 1M-token context window and native video/speech input plus scientific reasoning. 3.1 Pro tops GPQA Diamond 94.1% and ARC-AGI-2 77.1% to claim science-reasoning dual crowns, at $2/$12—1/6 of Claude. 3.8 Flash delivers agentic coding results close to frontier models at $0.75/$3.75 (Terminal-Bench 2.1 89.4%; DeepSWE v1.1 73.7%), with the same introductory pricing across 3.6, 3.7, and 3.8.
