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.

## GPT Image 2.6 GPT Image 2.6 uses the same generation, editing, asynchronous task, and billing APIs as 2.5: | Model | Billing | | --- | --- | | `gpt-image-2.6-flare` / `gpt-image-2.6-flare:reverse` | 0.22 Credits/image | | `gpt-image-2.6-sunburst` / `gpt-image-2.6-sunburst:reverse` | 0.22 Credits/image | | `gpt-image-2.6-flare:official` | Same as 2.5 official, billed based on actual Token usage | | `gpt-image-2.6-sunburst:official` | Same as 2.5 official, billed based on actual Token usage | Available quality options are `auto`, `low`, `medium`, `high`, `xhigh`, and `max`; use `auto` for size or a `WIDTHxHEIGHT` that meets the above constraints. This API supports `png`, `jpeg`, and `webp`; SVG/GIF are not currently supported. Editing supports JSON image URLs and multipart file uploads. `:reverse` is an explicit alias for the standard version of the same name. Please use the full model name; do not pass `gpt-image-2.6`.

Operating System

Configuration Method

Connect the current service in Claude Code:

Current project: Merge the mcpServers service entry below into .mcp.json in the project root directory, retaining the existing configuration.
Current user: Run the command below in the terminal; the configuration can be reused across projects.
Project configuration requires setting ACEDATACLOUD_API_TOKEN in the terminal: use export ACEDATACLOUD_API_TOKEN='YOUR_API_TOKEN' on macOS/Linux, and $env:ACEDATACLOUD_API_TOKEN = 'YOUR_API_TOKEN' in Windows PowerShell; replace YOUR_API_TOKEN with your AceDataCloud API Token.
Run claude in the same terminal where this variable has been set; new terminals or desktop-launched clients must also be able to read this variable.
After entering the Claude Code session, run /mcp to confirm that the service is connected and the tools have been loaded; when using the project configuration for the first time, check and approve the service as prompted.

export ACEDATACLOUD_API_TOKEN='YOUR_API_TOKEN'
claude mcp add --scope user --transport http 'openai-mcp' 'https://openai.mcp.acedata.cloud/mcp' --header 'Authorization: Bearer ${ACEDATACLOUD_API_TOKEN}'
