Frequently Asked Questions
Common questions about using the OpenAI API
Ace Data Cloud provides a proxy interface fully compatible with the official OpenAI format, without the need to register an OpenAI account or bind an overseas credit card. One API Key can access multiple models such as OpenAI, Claude, Gemini, Grok, etc.
GPT-5 is OpenAI's latest flagship model, surpassing GPT-4o in reasoning, creativity, and knowledge capabilities. GPT-4o is a well-validated cost-effective choice, suitable for cost-sensitive scenarios.
Models like o3, o3-pro, and o4-mini perform deep thinking before providing answers, particularly suitable for tasks requiring deep reasoning such as mathematical calculations, logical reasoning, and code analysis. o3-mini and o4-mini offer lower-cost reasoning capabilities.
GPT Image 1 / 1.5 is OpenAI's latest native image generation model, directly integrated into the GPT model, supporting more natural text-image interaction. DALL·E 3 is a dedicated image generation model, supporting various quality and size options including Standard/HD.
It is recommended to use text-embedding-3-small, which has the best cost-performance ratio ($0.0027 / million Tokens). For higher precision, use text-embedding-3-large ($0.017 / million Tokens). ada-002 is an older model, compatible but not as cost-effective as v3.
