Visual intelligence is fragmented today. OCR, layout, detection, segmentation, pose, and transcription models each ship their own input format, output schema, and pricing. The Gateway is an open-weight visual intelligence platform you can own. Call open-weight VLMs, ViT models, and other specialized vision models through one OpenAI-compatible API, swap models by changing model, and run them on our GPUs or yours. We orchestrate the models, keep the GPUs busy, and benchmark the VLMs, so you can ship the pipeline. Start with the quickstart.

Unified Interface for Visual Intelligence

Point any OpenAI client at the base URL and send your API key. Each response reports its cost in usage.cost. See Pricing and Rate limits.

Why the Gateway

  • Build on open-weight models: No vendor or frontier-model lock-in. Swap open-weight VLMs, ViT models, and other specialized vision models by changing model, and compare output and cost side by side. See Models.
  • Our GPUs or yours: Use these models on our GPUs with no hardware to provision, at a published rate on the live model catalog. Or deploy the same models onto your own GPUs with our platform.
  • Uncompromised quality: We are not another LLM serving provider. Each model is tuned and checked for visual quality. The aim is the best quality per dollar for vision.
  • Orchestration built-in: Worker parallelism, retries, failure handling, GPU utilization, and response healing run on our side, not in your code. Multi-page PDFs are rasterized and fanned out per page, with no splitting or stitching.
  • Agent ready: The MCP server exposes file-reading tools to any MCP-aware framework. System One answers typed questions in one read.
