AI data annotation platform and managed labeling services for AI training data
Bounding boxes, polygons, keypoints, semantic segmentation, 3D point cloud cuboids, text/NLP tagging and RLHF dataset creation in one platform.
Automated labeling assistance across images, point clouds and audio reduces manual effort while maintaining accuracy standards.
Project management adapts to your team structure with customizable workflows, progress tracking and detailed performance reporting.
Real-time feedback plus customizable batch QA rules catch issues early and enable targeted human review.
One API key for hundreds of AI models from every major provider
Six hundred plus models for text, image, video, audio, transcription, embeddings, and reranking behind one OpenAI-compatible API.
Requests are rerouted to another provider on outages or rate limits by default, so you don't write custom retry logic.
The auto-router selects a model and provider per request using live marketplace performance and pricing data.
Track spend, tokens, and usage per model, provider, and team member in one place, including bring-your-own-key usage.

Human-validated training data and evaluation services for frontier AI models
SpecialistDelivers exceptional inference speed and high-throughput performance for open models, but focuses primarily on hosted weights rather than multi-provider aggregation.

Free / Open-sourceProvides self-hosted and Python SDK control over 100+ LLMs, but requires setting up your own infrastructure.

SpecialistLow-cost serverless inference APIs for 200+ open models

One unified API for 100+ AI models, with insurance when output disappoints
