OpenAI's flagship multimodal assistant powered by GPT-6 and GPT-5.6 for reasoning, coding, and deep research.
Automatically routes prompts or lets users select between Instant responses and Medium, High, or Extra High thinking depth across GPT-5.6 Luna, GPT-5.6 Sol, and flagship GPT-6 Pro/Astra models.
Asynchronous software engineering and task agents that clone repositories, run terminal tests in sandboxed environments, resolve complex bugs, and submit pull requests.
Browses dozens of primary web sources, academic papers, and connected workspace documents over several minutes to compile structured, citation-backed analytical reports.
Provides a split-screen editor for inline prose and code revisions alongside low-latency voice conversations with live screen and camera grounding.

One OpenAI-compatible API key for 500+ AI models
Replace separate OpenAI, Anthropic and Google credentials with a single key and switch models by changing one line of code.
Route text, reasoning, coding, image, audio and video workloads through one OpenAI-compatible base URL without rewriting your app.
Line-item pricing per model with discounts below official vendor rates, pay-as-you-go with no monthly subscription or minimum spend.
A real-time dashboard tracks spend, latency and call volume so you can set budget alerts and compare models side by side.
