Invisible forensic watermarks that identify who leaked your data
Each recipient's copy of an email, document or image carries a different hidden mark, so a single leaked artifact points to one person.
The Luma image mark is engineered to survive printouts, photocopies, mobile photos and compression, where metadata-based tagging fails.
Marks everything shown on a display, covering any app or file type including browsers, collaboration tools and AI assistants.
Upload a leaked file, screenshot or photo and get back the source recipient with a confidence score and chain-of-custody documentation.
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.
