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.
Turn text and images into cinematic AI videos
Generate clips by describing a scene, character and action in a text prompt, then pick aspect ratio, resolution and duration.
Animate a still image or reference photo by combining it with a short prompt to bring the scene to life.
Choose output resolution up to 4K, aspect ratios from 16:9 to 1:1, and clip lengths of 5 or 10 seconds.
Download finished videos without a watermark, even on free usage, and export in HD.
Provides direct API access to Google's Gemini models with generous free prototyping tiers, but lacks OpenAI's ecosystem breadth.
