Core capabilities of Hy3
Hy3 is a 295B Mixture-of-Experts model with 21B active parameters and a 256K context window, optimized for reasoning, agent workflows, and productive work.
256K long-context understanding
Work with long documents, dense instructions, and extended conversations in one context.
Adaptable reasoning depth
Scale from a quick answer to deeper analysis when a task needs more thought.
Tool calling and structured output
Connect tools and data, then return results in a structure other systems can use.
Coding and software engineering
Plan features, explain code, and work across files, data, storage, and CI/CD.
Documents and office workflows
Analyze long documents, automate office tasks, and support financial models.
Multi-turn intent tracking
Keep goals and earlier instructions in view across a longer conversation.
Where Hy3 creates practical value
Hy3 is designed for complex real-world work that combines deep analysis, long context, code, and tool-enabled execution.
Reason through difficult problems
Break mathematics, technical analysis, planning, and multi-step decisions into workable steps.
Develop and debug software
Plan features, understand code, and coordinate changes across several files.
Analyze long documents
Review reports, specifications, and research without losing the main thread.
Build structured business outputs
Turn loose instructions into organized data, reports, office tasks, and financial-modeling steps.
Coordinate tool-enabled research
When tools are connected, retrieve, compare, and summarize information in one workflow.
Keep complex work on track
Carry goals and constraints through a task as it changes.
How Hy3 approaches complex work
Hy3 combines instruction following, long-context understanding, adaptable reasoning, and tool use to carry complex work beyond a single short answer.
Understand the full brief
Keep long briefs, documents, and earlier instructions in one working context. Results still depend on the task.
Match reasoning depth to the task
Use a direct answer for simple work or deeper reasoning for mathematics, code, and planning.
Coordinate multi-step execution
With compatible tools, continue across several steps and recover when a tool fails.
Why Hy3 works for production workflows
Hy3 was refined with feedback from more than 50 product teams, focusing on reliability as well as model scale.
Efficient Mixture-of-Experts design
The Mixture-of-Experts design activates 21B of 295B parameters for each token.
More dependable tool behavior
Published evaluations show steadier tool calls, better recovery, and more consistent formats.
Better long-horizon reliability
Published evaluations report fewer hallucinations and stronger focus across multi-turn work.
