Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Tencent / Hy4
proDescription
Tencent's newest flagship and the full release after Hy4 Preview. Hy4 adds image understanding and computer use, and leads Tencent's blind finance test with a score of 3.04 against DeepSeek V4.1 Flash, Kimi K3.1 Pro, and GLM-5.3. It reads text and images across a very large context, reasons before answering, and powers Tencent's WorkBuddy and CodeBuddy apps. Tencent plans to release open weights later.
OpenAI / GPT-5 Nano
lightDescription
OpenAI's smallest and cheapest GPT-5 model, built for speed above all. GPT-5 Nano is made for summarisation, classification, and other well-defined tasks that run at high volume. It reads text and images, with adjustable reasoning effort. Reasoning depth is shallow by design and its knowledge is dated. The trade is cost: it is among the cheapest models in the catalog.

Why Use Hy4 and GPT-5 Nano?
Aymo gives you more than access to individual models—it provides a complete multi-model AI workspace designed for productivity.
Tencent / Hy4
proMeasured Coding Scores
Artificial Analysis measured 37% on Terminal-Bench 4.0 and 31% on FrontierCode 2.0. Top closed models still score higher on the hardest coding tests.
Reasoning And Computer Use
Reasons through problems before it answers. Tencent built Hy4 for long tasks, including computer use across command-line and graphical interfaces in its own apps.
Room For Long Inputs
A very large context window of about 1 million tokens, the same as Hy4 Preview. Load long reports, filings, or a full codebase in one request.
Top Finance Score
In Tencent's blind test of 579 real financial tasks, Hy4 scored 3.04, ahead of DeepSeek V4.1 Flash at 2.97 and Kimi K3.1 Pro and GLM-5.3 at 2.68.
Workplace Task Results
Tencent reports a 96.15% pass rate on its WorkBuddy tests, ranking first in nine of 12 scenarios. It has no native web search, so current data comes through connected tools.
New Image Input
Hy4 Preview read text only. The full Hy4 adds image understanding, so you can send screenshots, charts, or diagrams with your question on Aymo.
OpenAI / GPT-5 Nano
lightCoding Sub-Tasks
Suited to small, well-scoped coding jobs and to acting as a fast sub-agent inside a larger system, rather than tackling whole problems. Reasoning depth is limited, so keep the scope tight.
Adjustable Reasoning Effort
Reasoning effort runs from minimal through low, medium, and 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 Documents
A large context window, enough to summarise long reports or classify big batches of text in a single pass without splitting the input into separate requests.
Summarisation And Classification
OpenAI names summarisation and classification as its core uses. Built to process high volumes of text quickly and cheaply rather than to produce polished long-form writing.
Analysis On Older Knowledge
Its training data is dated by current standards, so it is fine for processing text you supply but weaker on recent events, which need live sources rather than the model's own knowledge.
Text And Image Input
Reads text and images, so you can send screenshots or scanned pages alongside your prompt. Output is text only. OpenAI states audio and video are not supported.
