Capabilities
A single API for every model you'll ever need.
Frontier reasoning
Multi-step planning, chain-of-thought, and tool use that holds up under pressure. Mark reasons for minutes, not seconds — and gets the hard problems right.
Sub-200ms inference
Streaming first, globally distributed, edge-cached. Mark responds before your users notice they asked.
Vision, voice, code
Native multimodal — drop in images, audio, PDFs, repositories. Mark understands them all in one context window.
Models
Pick the right brain for the job.
Four specialized models, one unified API. Route by complexity, latency, or cost — Mark handles the rest.
