Overview
MiniMax-M3 vs GPT-5 Mini Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
MiniMax / MiniMax-M3
proDescription
MiniMax’s flagship, and the first open-weight model to combine frontier coding, a million-token context, and native multimodality in one place. M3 reads text, images, and video, and can operate a desktop computer. Multimodal training ran from step zero rather than being bolted on later. Weights are open. Built for long-horizon agent work that runs for hours rather than seconds.
OpenAI / GPT-5 Mini
proDescription
OpenAI's smaller, faster GPT-5 model is built for well-defined tasks at low cost. GPT-5 Mini handles coding, writing, and analysis with the same reasoning-effort control as its larger siblings, at a fraction of the price. It reads text and images across a 400,000-token context. Its knowledge is dated, and OpenAI now points to newer models, but it remains a capable, economical everyday option.

MiniMax / MiniMax-M3
proFrontier Coding in an Open Model
MiniMax reports significant gains over the previous generation in bug fixing, front-end and back-end development, and performance optimisation, approaching leading closed-source models. Autonomous task decomposition and tool invocation are built in.
Thinking You Toggle Per Request
Thinking mode can be switched on or off at request time, and supports interleaved thinking blocks. Turn it off for routine work, and on when a task needs multi-step reasoning before the answer.
Room for Repositories and Logs
Up to a million tokens, with a guaranteed minimum of 512,000. MiniMax built this for long-range agent tasks, whole-codebase work, and long-video understanding, so paper, code, and logs fit at once.
Writing From Charts and Papers
Reads charts, curves, and formulas directly from source documents and writes from them. MiniMax demonstrated it reproducing a research paper unaided, producing commits and experimental figures across a twelve-hour run.
Autonomous Research and Browsing
MiniMax reports strong autonomous browsing and information retrieval, plus agentic performance on office workflows including search and Office-suite tasks. Suited to research that requires finding material, not just reading it.
Images, Video, and Computer Use
Text, image, and video input, natively. MiniMax's API accepts image and video content parts directly. It can also operate a desktop computer, which is rare in an open-weight model.
OpenAI / GPT-5 Mini
proCost-Efficient Coding
Built for coding help at scale rather than the hardest engineering problems. Handles routine generation, review, and explanation reliably, and its low price makes it suited to high-frequency use inside applications.
Adjustable Reasoning Effort
Reasoning effort runs from minimal through low, medium, and high, so you trade thinking time against cost per request. Reasoning tokens are supported, so the model can work through a problem first.
Room For Long Documents
A 400,000-token context window, roughly 300,000 words. Enough for long reports, large contracts, and substantial codebases in one session, though short of the million-token frontier models.
Everyday Writing
Handles emails, summaries, documentation, and general content reliably. Aimed at clear, correct output on ordinary writing tasks rather than the polished long-form work of the flagship models.
Analysis On Dated Knowledge
Its knowledge belongs to the GPT-5 generation, with a September 2024 cutoff. That is dated, so time-sensitive work needs live sources rather than the model's own training.
Text And Image Input
Reads text and images in the same prompt, so you can send screenshots, charts, or scanned pages alongside your question. Output is text only.
