DeepSeek V4 Pro 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 Pro
allDescription
DeepSeek’s flagship is the model it calls the best open-source system available today. DeepSeek positions itself as the leading open model for world knowledge, math, STEM, and coding, rivaling top closed-source systems. It handles a one-million-token context and offers reasoning modes from fast to maximum effort. Text only, with no image input. Released as a preview under an MIT license, so the weights are public.
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 Pro 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 Pro
allAgentic Coding
DeepSeek claims open-source state of the art on agentic coding benchmarks, and says the model already drives its own in-house coding work. Built for full-codebase analysis and multi-step engineering rather than single edits.
Adjustable Reasoning
Runs in thinking or non-thinking mode, with effort from fast responses through to maximum reasoning. At maximum effort the reasoning trace gets long, so plan for it to consume real context.
Reads Entire Codebases
A very large context window, which DeepSeek made the default rather than a paid upgrade. Feed it a whole repository, a document set, or a long agent trace at once.
Writing And Analysis
Handles writing and analysis alongside code. DeepSeek says it leads all current open models on world knowledge, trailing only one closed frontier model, which is what most writing rests on.
Strong Knowledge Without Search
Knows a great deal, but fetches nothing current on its own. DeepSeek does not list native web search among its capabilities, so anything recent has to come from you.
Text Only Input
Reads and writes text. It does not accept images, audio, video, or PDFs. If your work involves screenshots, diagrams, or scanned pages, this is not the model for it.
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.
