GPT-5.6 Luna vs Hy3 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
OpenAI / GPT-5.6 Luna
maxDescription
OpenAI's fastest and cheapest GPT-5.6 model, built for high-volume, latency-sensitive work. Luna handles quick edits, first-pass drafts, and simple pages at a low cost, matching the nano tier of earlier GPT generations. It shares the family's very large context, recent knowledge, and text-and-image input, and supports the same reasoning range and web search, so it is capable well beyond its 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.

OpenAI / GPT-5.6 Luna
maxFast Cheap Coding
Built for quick edits, first-pass drafts, and simple pages at high volume. Best on well-scoped, verifiable coding work where speed and low cost matter more than tackling the hardest problems.
Reasoning Effort You Set
Shares the family's full reasoning-effort range, from none up to the highest settings. Runs shallow and fast by default, with room to push harder when a task genuinely needs it.
Room For Long Inputs
The same very large context window as its larger siblings. Big enough to summarise long documents or process large batches in one pass, unusual capacity for a model at this price.
High-Volume Drafting
OpenAI positions it for cost-sensitive, high-volume workloads. Suited to first drafts, quick rewrites, and repetitive text work at scale rather than polished long-form or high-stakes writing.
Web Search And Recent Knowledge
Supports web search as a tool and shares the family's recent knowledge base. Together, those keep it current on live questions despite its budget positioning.
Text And Image Input
Reads text and images in the same prompt, so you can send screenshots 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.
