Frequently Asked Questions
Common questions about using the OpenAI API
What is the difference from using the official OpenAI API directly?›
Ace Data Cloud provides proxy APIs fully compatible with the official OpenAI format, with no need to register an OpenAI account or link an overseas credit card. A single API Key can access models from OpenAI, Claude, Gemini, Grok, and more.
What is the difference between GPT-5 and GPT-4o?›
GPT-5 is OpenAI's latest flagship model, comprehensively surpassing GPT-4o in reasoning, creativity, and knowledge capabilities. GPT-4o is a well-validated, cost-effective choice suitable for cost-sensitive scenarios.
What scenarios are o-series reasoning models suitable for?›
Reasoning models such as o3, o3-pro, and o4-mini perform deep thinking before providing answers, making them especially suitable for tasks requiring in-depth reasoning, such as mathematical calculations, logical reasoning, and code analysis. o3-mini and o4-mini offer lower-cost reasoning capabilities.
What is the difference between GPT Image and DALL·E 3?›
The GPT Image series supports image generation and editing; GPT Image 2.5 Flare focuses on speed, while Sunburst focuses on high fidelity and fine-grained control. Both 2.5 models offer :official variants billed according to actual Token usage. DALL·E 3 is a dedicated image generation model that supports multiple Standard/HD quality and size options.
Which model is best for Embeddings?›
text-embedding-3-small is recommended for the best value ($0.0027 / million Tokens). For higher accuracy, use text-embedding-3-large ($0.017 / million Tokens). The legacy ada-002 is no longer available; existing indexes need to have their vectors regenerated when upgrading.
