GPT-5.4 Nano vs Hy3 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
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.
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.

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.
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.
