Gemini 3.8 Flash vs GPT-5.4 Nano Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Google / Gemini 3.8 Flash
proDescription
Google's most intelligent Flash-tier model, built on 3.7 Flash and tuned to work harder per task. Gemini 3.8 Flash pushes further into software engineering and agentic knowledge work, taking more reasoning steps and calling tools iteratively rather than answering in a single pass. It reads text, images, audio, video, and PDFs across a very large context, grounded in live search, and its knowledge is among the most recent in the catalog.
OpenAI / GPT-5.4 Nano
proDescription
OpenAI's smallest and cheapest current-generation model, built for speed and volume. GPT-5.4 Nano excels at classification, data extraction, ranking, and coding sub-tasks, and works well as a fast sub-agent inside larger systems. It reads text and images, supports web search, and follows instructions reliably. Reasoning depth is shallow by design, traded for very low latency and cost at scale.

Google / Gemini 3.8 Flash
proDiligent Agentic Coding
Google reports gains of over 3.7 Flash in software engineering and agent workflows. At higher effort, it takes extra reasoning steps and iteratively calls tools, navigating roadblocks rather than answering in a single pass.
Effort You Set
Three thinking levels, low, medium, and high, defaulting to medium, trading reasoning depth against cost and latency. Deep thinking is on by default, so lower the level for latency-sensitive work.
Room For Repositories
A very large context window, carried over from the Flash line. Load a full repository, a long document set, or hours of media in one request and work across it without chunking.
Knowledge Work At Scale
Google reports gains in long-horizon and enterprise knowledge work alongside coding. Suited to document-heavy workflows over large, mixed source material, with iterative tool use built in.
Search And Recent Knowledge
Its knowledge is among the most recent in the catalog, and it supports search grounding. Google notes coverage varies by domain, so live search still matters for the newest information.
Text Image Audio Video
Google's model card lists text, images, audio, video, and PDFs as input. Output is text. Among the broadest input ranges available, and unusual in handling both audio and video.
OpenAI / GPT-5.4 Nano
proCoding Sub-Agents
OpenAI positions it for coding sub-tasks and as a fast sub-agent in multi-model architectures. Built for small, well-scoped jobs run at high frequency rather than whole engineering problems.
Adjustable Reasoning Effort
Reasoning effort ranges from minimal to high. Even at higher effort, it is a shallow reasoner by design, so it suits speed-sensitive work rather than hard multi-step problems.
Room For Long Inputs
A large context window, enough to classify or extract from big batches of text in a single pass. Ample for the high-volume work it is built for without splitting the input.
Extraction And Ranking
OpenAI names classification, data extraction, and ranking as its core uses. Built to process structured, repetitive text work quickly and cheaply rather than to write long-form content.
Web Search For Current Facts
Supports web search as a tool, so it can pull live information into an answer. Useful in background and real-time systems where the data needs to be current.
Text And Image Input
Reads text and images, so you can send screenshots or scanned pages alongside your prompt. Output is text only. Audio and video are not supported.
