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
+
Industry-standard SDKs, Structured Outputs, and built-in Responses API tools minimize boilerplate agent code
Limitations
–Long-context requests exceeding the standard window threshold trigger roughly 2x higher per-token billing rates
–Flagship GPT-6 Astra ($10 input / $50 output per 1M tokens) is significantly more expensive than Claude Opus 5.5 ($4/$20) and Grok 4.7 ($2/$6)
–Regional data residency endpoints incur a 10% price uplift on models released after March 2026
