Overview
MiMo-V2.5-Pro vs GPT-5.4 Nano Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
MiMo / MiMo-V2.5-Pro
proDescription
Xiaomi’s flagship, built for autonomous work that runs for hours rather than seconds. MiMo-V2.5-Pro sustains trajectories spanning thousands of tool calls, holding coherence across a million-token context. Xiaomi reports it building a full compiler unaided in a few hours. It is also unusually token-efficient, reaching comparable results while spending far less. Text only. Open weights under a permissive licence.
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 MiMo-V2.5-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.
MiMo / MiMo-V2.5-Pro
proHours-Long Software Engineering
Xiaomi documents it writing a complete compiler from scratch across hundreds of tool calls with a perfect test score, and an eight-thousand-line video editor in a single autonomous run. Built for the whole job.
Reasoning With Harness Awareness
Xiaomi describes the model actively managing its own memory and shaping how its context fills as it works. In its own tests it diagnosed a regression it had caused, recovered, and carried on.
Usable Million-Token Context
Xiaomi's long-context testing shows it still retrieving accurately deep into a million tokens where its predecessor collapses entirely. The capacity is proven rather than merely advertised.
Structured Artifact Generation
Its coding evaluation covers repository understanding, project building, code review, structured artifact generation, and planning. Strongest when producing something with a shape rather than free-flowing prose.
Research Through Tool Use
Built to call tools, read results, and adjust. Xiaomi demonstrated it driving a circuit simulator in a closed loop, reading waveforms and tuning parameters until every target was met. No native web search.
Text Only Input
Reads and writes text. No image, audio, or video input. Screenshots, mockups, diagrams, and scanned pages are outside what this model can read.
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.
