GPT-6.1 Terra vs Hy3 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
OpenAI / GPT-6.1 Terra
proDescription
OpenAI's fast, efficient mid-size model in the GPT-6.1 family and the upgrade to GPT-5.6 Terra. OpenAI reports gains over GPT-5.6 Terra in coding, visual reasoning, and factual accuracy, and near-Sol results on MMMU-Pro, at half the per-token price of GPT-6.1 Sol. It reads text and images across a very large context, supports web search, and offers reasoning effort from none to max.
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-6.1 Terra
proCoding Above 5.6 Terra
OpenAI reports large gains over GPT-5.6 Terra on software engineering tests, including Terminal-Bench 4.0, which checks how well a model fixes problems from the command line.
Effort None To Max
Reasoning effort runs none, low, medium, high, xhigh, and max, defaulting to medium. Lower levels answer faster, and higher levels spend more time thinking on hard problems.
Room For Whole Projects
A very large context window, with room for a full codebase or a long set of documents in one request. Replies can run up to 128,000 tokens.
Clear, Natural Writing
OpenAI built GPT-6.1 Terra for three things: visual reasoning, precise computer use, and natural writing. That makes it a good fit for everyday drafts, replies, and summaries.
Fewer Factual Errors
Supports web search for current information. OpenAI reports its error rate on a hard factual test fell from 53.6% with GPT-5.6 Terra to 16.7%.
Text And Image Input
OpenAI lists text and image input, with text output. On MMMU-Pro, a visual reasoning test, it nearly matches GPT-6 Astra and GPT-6.1 Sol.
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.
