GPT-5.6 Terra vs Hy3 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
OpenAI / GPT-5.6 Terra
maxDescription
OpenAI's balanced everyday model in the GPT-5.6 family, and its new default GPT for most work. Terra delivers roughly the quality of the previous flagship at about half the cost, with strong coding, agentic work, and design sense. It reads text and images across a very large context, supports live web search, and lets you set reasoning effort per request.
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-5.6 Terra and Hy3?
Aymo gives you more than access to individual models—it provides a complete multi-model AI workspace designed for productivity.
OpenAI / GPT-5.6 Terra
maxCoding With Design Sense
OpenAI tuned this generation for front-end taste, producing tasteful, functional interfaces from high-level direction. It can inspect the rendered result and refine it, rather than emitting code and hoping it works.
Reasoning Effort You Set
Reasoning effort runs from none through low, medium, high, and higher settings, so you control how hard the model works per request. OpenAI positions Terra as the balanced baseline for most API work.
Room For Whole Projects
A very large context window, big enough to hold a substantial project in view so the model stops losing track of files across a long build. Prompts above a high threshold are billed at a higher rate.
Professional Knowledge Work
OpenAI positions the family for professional knowledge work, science, and design alongside coding. Terra suits that work at a cost that makes running it at volume practical rather than reserved for the hardest tasks.
Web Search And Recent Knowledge
Supports web search as a tool, and its knowledge is among the most recent in the catalog. Together those cover current questions well, with the search filling anything past the training cutoff.
Text And Image Input
Reads text and images in the same prompt, so you can send screenshots, diagrams, or scanned pages alongside your question. Output is text only. Audio and video are not accepted.
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.
