Gemini 3.5 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 3.5 Flash
proDescription
Google's newest Flash-tier model, and an unusual one. Google describes it as delivering near-Pro intelligence at Flash cost and speed, with Pro-level coding proficiency and parallel agentic execution. It reads text, images, audio, video, and PDFs across a one-million-token context window. Fast, cheap, and strong on tool use. Still a preview release, with the same modest output ceiling as the rest of the Gemini 3 line.
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 3.5 Flash
proCoding at Flash Speed
Google claims Pro-level coding proficiency at Flash-tier cost, and lists agentic coding among its core strengths. Built for parallel agent execution, where several tasks run at once rather than one after another.
Adjustable Thinking
Thinking runs at minimal, low, medium, or high, defaulting to medium rather than high. That makes it cheaper and faster out of the box, with room to push harder when a problem needs it.
Handle full Codebases Context
A one-million-token context window, the same as Google's Pro tier. Load a full repository, a long document set, or hours of media, and work across all of it in a single session.
A Modest Output Ceiling
Writes up to 64,000 tokens in a single response, well short of what most frontier models produce. Enough for reports and documentation, but long-form generation has to be split into parts.
Search, Maps, and URL Grounding
Supports Google Search, Grounding with Google Maps, File Search, URL Context, and code execution, and can combine them in one request. Its knowledge cutoff is January 2025, so grounding matters.
Reads Video, Audio, and PDFs
Text, images, video, audio, and PDFs, all handled natively. Output is text only. Very few models accept video or audio input at all, which makes this range genuinely uncommon.
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.
