DeepSeek V4.1 Flash vs GPT-5.4 Nano Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Deepseek / DeepSeek V4.1 Flash
proDescription
DeepSeek's efficient multimodal model, and the release that brought vision to its Flash line. V4.1 Flash reads text and images, activates only a small fraction of its parameters per token, and holds a very large context. A new architecture uses less compute for long inputs than for generation, making it fast and cheap for input-heavy agent work. Strong on coding and long-context tasks. Free to start on Aymo. Open weights under an MIT license.
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.

Why Use DeepSeek V4.1 Flash and GPT-5.4 Nano?
Aymo gives you more than access to individual models—it provides a complete multi-model AI workspace designed for productivity.
Deepseek / DeepSeek V4.1 Flash
proAgentic Coding
DeepSeek reports sharp coding gains over the previous Flash model, tuned for software agents and long-horizon tasks. Built for repository-scale work and tool-driven agent loops rather than single edits.
Reasoning You Adjust
Reasoning effort ranges from off to maximum. DeepSeek reports strong results with high effort, though independent testing notes that it is verbose and can use many tokens.
Efficient Long Context
A very large context window, with a new architecture that cuts the memory cost of holding long inputs to roughly a quarter of the previous Flash model. Built for input-heavy agentic workloads.
Document And Code Output
DeepSeek reports gains in document creation alongside code. Suited to long technical documentation and structured output at speed, rather than the most polished long-form writing.
Analysis Without Search
Reasons over what you supply, including images, and reach strong scores on knowledge and long-context benchmarks. It has no native web search, so anything up to date comes through connected tools.
Text And Image Input
DeepSeek's model card lists native text and image input, with text output, integrating vision into the model rather than a separate variant. Screenshots, diagrams, and charts are now within reach, unlike earlier DeepSeek models.
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.
