ICapabilities
One model, many jobs
A reasoning engine for real work.
Ox Alpha combines deep reasoning with a huge context window and native tool use — the same model behind serious agentic and coding workloads.
Deep reasoning
Step-by-step thinking for math, logic and multi-constraint problems that shallow models miss.
01Coding
Reads whole codebases, plans changes across files and iterates on failures until it works.
02Agentic workflows
Built for sustained, long-horizon tasks with tool calling and multi-step execution.
031M token context
Feed entire repositories, books or document sets and keep the whole picture in view.
04Vision
Combines text with visual context — screenshots, diagrams and images.
05Structured output
Reliable JSON and schema-constrained responses for production pipelines.
06IIUse cases
What people build with it
From a quick question to a full engineering run.
Research02
Dig deep
Reason over long documents and synthesise clear answers.
Agents03
Automate
Drive multi-step tool workflows that run to completion.
Analysis04
Make sense of data
Turn messy inputs into structured, actionable output.
Writing05
Draft & edit
Long-form writing with a consistent, context-aware voice.
Vision06
Read the screen
Explain screenshots, diagrams and UI mockups in context.
IIIPerformance
Numbers, not adjectives
Frontier quality, monitored around the clock.
Routed directly through OpenRouter to a single dedicated provider — no routing guesswork, healthy failover.
