Cloud-native computer vision APIs with one unified REST interface
An optimized endpoint that strips image backgrounds for product photos, car listings, collages and e-commerce catalogs, with natural shadow options.
Detect, analyze and recognize faces for identity, demographics or visitor analytics use cases.
Score images for not-safe-for-work sexual content so user-uploaded media can be filtered before it reaches your audience.
Recognize brand logos, detect and classify objects, label scenes, count furniture, apparel and other items in images.
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.
