Model Card
Gemini 3.1 Flash-Lite is Google's fastest and most cost-efficient model in the Gemini 3.1 series, designed for high-volume, latency-sensitive workloads.
It delivers 2.5x faster time-to-first-token and 45% higher output throughput than Gemini 2.5 Flash, scoring 86.9% on GPQA Diamond and 76.8% on MMMU Pro. An Intelligence Index score of 34 — nearly triple that of 2.5 Flash-Lite — puts it well above prior budget-tier models at the same price point.
The model supports text, image, video, audio, and PDF input with a 1M token context window and configurable thinking levels. It's the right choice for developers building translation pipelines, content moderation systems, classification tasks, or any application where throughput and cost matter most.

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. Introductory pricing matches Argon at $2 per million input tokens and $10 per million output tokens, rising to $4 and $20 later, and cached input costs 95% less. It suits coding agents, security tooling, and long-document analysis.

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.
