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.
Build and launch custom AI chat assistants from your own data — no code required
Configure prompts, welcome messages, conversation starters and persona in a visual dashboard instead of writing code.
Ground answers in your website pages, uploaded documents or spreadsheets so the bot speaks to your actual offer.
Publish the assistant as a chat widget visitors can use directly on your site without leaving the page.
Collect visitor details during conversation so sales conversations can continue after the chat ends.
Provides direct API access to Google's Gemini models with generous free prototyping tiers, but lacks OpenAI's ecosystem breadth.
