Turn free text into structured, model-ready data with AI-assisted annotation.
Mark up documents and free text to extract names, entities, relationships and fields into clean tabular or JSON output.
Built for NLP and ML workflows, so exported datasets plug into model training pipelines without heavy reformatting.
AI assistance proposes labels and extractions to reduce repetitive manual work, while you keep final control over correctness.
An interactive demo lets you test the annotation flow before committing to a full project setup.
Enterprise developer platform and API for deploying GPT-6 Astra, Sol, Luna, and realtime multimodal agents.
Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.
Provides direct API access to Google's Gemini models with generous free prototyping tiers, but lacks OpenAI's ecosystem breadth.
