Free During the Preview — No Token Bill
Ox Alpha is priced at $0.00 per million tokens for both input and output during its free stealth preview, so you can evaluate it on real coding, research, and agentic tasks before committing to a paid model.
$0 for input and output
Felo lists Ox Alpha at $0.00 per million tokens for both input and output as a free stealth preview. That makes it a no-cost option to test on your own prompts, though pricing may change when the model moves out of preview.
1M token context window
A 1,048,576-token input window with up to 131,072 tokens of output lets you work across large codebases, long documents, and mixed media in a single request.
Reasoning and tool calling
Ox Alpha supports chain-of-thought reasoning and tool calling with tool_choice and structured JSON output, so you can build and test agentic workflows during the free window.

Reasoning
A reasoning model designed for coding, sustained agentic work, and production workloads, with chain-of-thought output.
Tool Use & APIs
Function calling with tool_choice and structured JSON output (no strict JSON Schema). Prompts and completions are retained by the provider but not used to train.
Input Modalities
Text, image, and video in; text out. No separate pipelines required.
Native Multimodal — One Model, Every Input Type
Ox Alpha reads text, images, and video natively. No separate pipelines, no stitching models together.
Text & Code
Parses long documents, codebases, and structured data in a single pass, handling complex tables and large prompts without preprocessing.
Image & Charts
Feed screenshots, charts, and diagrams alongside written instructions to extract structured information or ask grounded questions.
Video Analysis
Analyze video alongside text and images, then ask for grounded answers or concise summaries of the material you provide.
Who Uses Ox Alpha
From individual developers to agent builders, Ox Alpha fits wherever you want a free, capable reasoning model to start with.
Agentic Coding
Use the free preview to evaluate Ox Alpha on your own repositories, code review, and coding-agent setup before choosing a paid production model.
Document & Data Analysis
Use the 1M-token context window to work across lengthy documents, structured data, and code in a single request when that context matters.
Multimodal Research
Combine text, image, and video input with written instructions to extract information, draft alternatives, or prepare material for review.
Agentic Workflows
With tool calling and structured JSON output, build and test agentic pipelines that call tools and return machine-readable results.
Long-Horizon Tasks
For multi-step work, compare Ox Alpha's quality, latency, and token usage against other models on representative tasks in the free window.
Production Evaluation
Use the free access to validate prompts, latency, and tool-call behavior before scaling a workflow to a paid model.
