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.
Photorealistic digital humans that respond in under 300 milliseconds
Avatars respond in under 300 milliseconds, so conversations feel immediate rather than delayed, and they keep listening, reacting and breathing while waiting for the user.
Rendering happens on-device instead of streaming video from the cloud, which cuts bandwidth to 10–15 KB/s and compute cost to roughly one hundredth of typical cloud video avatars.
Web, iOS and Android SDKs plus simple APIs let developers integrate digital humans into existing apps and agent stacks without a heavy backend.
Appearance, behaviour and voice can be tailored to your brand or AI experience, with natural, controllable motion rather than stiff scripted animation.
