Deepseek V4 Pro vs GPT-5 Nano Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Deepseek / Deepseek V4 Pro
proDescription
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 Nano
lightDescription
OpenAI's smallest and cheapest GPT-5 model, built for speed above all. GPT-5 Nano is made for summarisation, classification, and other well-defined tasks that run at high volume. It reads text and images, with adjustable reasoning effort. Reasoning depth is shallow by design and its knowledge is dated. The trade is cost: it is among the cheapest models in the catalog.

Why Use Deepseek V4 Pro and GPT-5 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
proAgentic 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 Nano
lightCoding Sub-Tasks
Suited to small, well-scoped coding jobs and to acting as a fast sub-agent inside a larger system, rather than tackling whole problems. Reasoning depth is limited, so keep the scope tight.
Adjustable Reasoning Effort
Reasoning effort runs from minimal through low, medium, and 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 Documents
A large context window, enough to summarise long reports or classify big batches of text in a single pass without splitting the input into separate requests.
Summarisation And Classification
OpenAI names summarisation and classification as its core uses. Built to process high volumes of text quickly and cheaply rather than to produce polished long-form writing.
Analysis On Older Knowledge
Its training data is dated by current standards, so it is fine for processing text you supply but weaker on recent events, which need live sources rather than the model's own knowledge.
Text And Image Input
Reads text and images, so you can send screenshots or scanned pages alongside your prompt. Output is text only. OpenAI states audio and video are not supported.
