OpenAI Platform

Enterprise developer platform and API for deploying GPT-6 Astra, Sol, Luna, and realtime multimodal agents.

GPT-6 & GPT-6.1 Model Lineup with 1.05M Context

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.

Configurable Reasoning Effort Controls

Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.

Responses API & Native Computer Use Tools

Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.

GPT-Live-1 Realtime Voice API

Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.

Strengths & Pros

+100-fold cost flexibility from GPT-6 Luna ($0.10/$0.50 per 1M tokens) up to frontier GPT-6 Astra ($10/$50 per 1M tokens)
+Unified 1.05M-token context window and 128K output limit across the entire flagship GPT-6 and GPT-6.1 family
+90% discount on cached input tokens and 50% Batch API discount dramatically reduce production inference bills
