GPT-5.4 Mini vs Hy3 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
OpenAI / GPT-5.4 Mini
proDescription
OpenAI's more affordable mid-tier model, built to balance capability and cost at scale. GPT-5.4 Mini handles chat, coding assistants, and agent workflows with reliable instruction following and solid multi-step reasoning. It reads text and images across a large context window, and supports web search and function calling. A practical production choice when you want current GPT quality without the flagship price.
Tencent / Hy3
lightDescription
Tencent’s open-weight reasoning model, built for agents rather than chat. Hy3 blends fast and slow thinking, switching between quick replies and deep reasoning, and Tencent tuned it hard for real production work: tool use, long agent loops, and search. It activates only a fraction of its parameters per token, so it is unusually cheap to run for its capability. Text only. Open weights, Apache 2.0.

Why Use GPT-5.4 Mini and Hy3?
Aymo gives you more than access to individual models—it provides a complete multi-model AI workspace designed for productivity.
OpenAI / GPT-5.4 Mini
proCoding Assistants At Scale
OpenAI positions it for coding assistants and agent workflows that run at volume. Handles routine generation, review, and multi-step engineering tasks reliably, with the cost profile to run them frequently.
Multi-Step Reasoning
Delivers dependable instruction following and multi-step reasoning with adjustable effort. Aimed at consistent performance across diverse tasks rather than the deepest reasoning of the frontier models.
Room For Large Codebases
A large context window, enough for extensive documents and substantial codebases in a single session. Ample for most production work without splitting the input into separate requests.
Everyday Professional Writing
Handles emails, documentation, reports, and general content reliably. Built for clear, correct output at scale rather than the polished long-form writing of the top-tier models.
Live Web Search Support
Supports web search as a tool, so it can ground answers in live sources rather than working only from training data. Useful when a task depends on current information.
Text And Image Input
Reads text and images, so you can send screenshots, charts, or scanned pages alongside your prompt. Output is text only. Audio and video are not supported.
Tencent / Hy3
lightProduction Software Engineering
Tencent reports strong software development, front-end design, and even game production, refined through its own WorkBuddy and CodeBuddy products. It concedes repository-scale coding to the strongest open rival but performs well on real, shippable work.
Fast And Slow Thinking
A hybrid reasoning design with selectable effort: a no-think mode for quick replies, and deeper modes for hard problems. That lets you spend reasoning only where a task needs it, keeping simple steps fast and cheap.
Long-Context Retrieval
Holds a large context and is tuned to parse messy, lengthy input while following complex rules. Tencent reports it powering agent workflows of hundreds of steps without losing the thread.
Office And Productivity Work
Tencent highlights office productivity, financial modelling, and document generation, including PowerPoint creation through its Yuanbao product. Built for structured, real-world business output rather than long-form prose.
Agentic Search And Tool Use
Its standout strength. Tencent reports leading the open field on agentic search and tool orchestration, retrieving, filtering, and integrating information across sources. Works with agent frameworks like OpenClaw, OpenCode, and Cline.
Text Only Input
Reads and writes text. No image, audio, or video input. Despite the Hunyuan family including media models, Hy3 itself is a pure reasoning and agentic language model, so screenshots and diagrams are outside what it reads.
