Enterprise AI training data, annotation and evaluation services
A large selection of ready-to-use, ethically sourced datasets across audio, image, video, text and multimodal formats, with advanced filtering and free samples.
Expert-verified labeling for text, audio, image and video using model-first, human-in-the-loop workflows for accuracy and fairness.
High-quality multilingual content for global AI systems, drawing on 500+ languages, dialects and locales.
Global, diverse data collection at scale for training, with privacy and security vetting on every dataset.
Run and build with open AI models locally or in the cloud
Install once and pull open-weight models by name; Ollama handles weights, quantization and versioning for you.
A built-in server exposes a straightforward REST API, so scripts, editors and agents can talk to local models with minimal setup.
Route requests to hosted open models when your laptop cannot hold the checkpoint you need, with per-token pricing and concurrency tiers.
Access families such as Llama, Qwen, DeepSeek, Gemma, Mistral and gpt-oss from a single interface.
