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.

Pick from neural AI voices with five reading styles so the output sounds like a person rather than a satnav, and set speed from 0.5x up to 2x.
Each sentence is highlighted while it is read, so you can follow along on screen, which is what makes it work for studying and proofreading by ear.
Paste plain text or upload a document, or drop in a link and the article text is extracted for you before playback.
Download the generated audio as an MP3 and keep it for commuting, the gym or any podcast app—no repeated regeneration needed.
