GPT-5.5 vs Hy3 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
OpenAI / GPT-5.5
maxDescription
OpenAI's frontier model is built for complex professional work. GPT-5.5 takes on demanding coding, deep reasoning, and analysis across very large inputs. It reads text and images, searches the web for current information, and lets you dial its reasoning effort up or down depending on how hard the problem is. Priced at the premium end of OpenAI's range, and built to earn it.
tencent / Hy3
lightDescription
Hy3 is Tencent Hunyuan's open-weight model, grouped in the Pro tier on Aymo. Rather than competing on raw size, it was built to match much larger models on real-world work, with Tencent tuning it using feedback from a wide range of its own product teams before release.

OpenAI / GPT-5.5
maxFrontier-Level Coding
OpenAI positions this as its model for the most complex professional work, with coding as the headline use. Handles large codebases, multi-step engineering tasks, and production-quality output.
Highest-Rated Reasoning
OpenAI's own model documentation rates its reasoning Highest, the top of the scale. Reasoning tokens are supported, so the model thinks before it answers, and you control how much thinking it does.
Large Context Window
1,050,000 tokens, among the largest available anywhere. Load an entire codebase, a full research corpus, or a large document set and ask questions across all of it. Prompts above 272,000 input tokens are billed at a higher rate.
Long-Form Professional Writing
Built for output that ships, not quick drafts. Writes up to 128,000 tokens in a single response, which covers long reports, full documentation sets, and extended technical writing without splitting the job up.
Live Web Research
Web search is a supported tool, so it can pull current information into an answer rather than working only from what it was trained on. Its knowledge cutoff is 1 December 2025, so anything more recent needs that search.
Text & Image Input
Reads text and images. OpenAI's documentation lists image as input-only and states that audio and video are not supported. File search is supported, so it can work across uploaded documents.

lightAgentic Tool Use
Run tasks that call on external tools reliably, holding up consistently across different agent setups and coding tools.
Everyday Coding
Get dependable coding help across common tasks, with results that compete well against much larger models.
Long-Horizon Workflows
Run multi-step tasks that unfold over an extended session, suited to workflows that need sustained follow-through.
Adjustable Thinking Depth
Choose between a fast, direct answer or a deeper, more thorough one, trading speed for reasoning depth as needed.
Cost-Efficient Performance
Get results that compete with much larger, costlier models, thanks to a design built around efficiency rather than raw size.
Web Research Tasks
Hand it research or information-gathering tasks that benefit from strong agentic tool use and reliable follow-through.
