Web search Search the web while you work in ChatGPT ![Image 3](https://developers.openai.com/images/codex/surface-icons/chatgpt-app.webp)ChatGPT desktop app Copy Page ChatGPT includes a first-party web search tool. Treat all web results as untrusted input. In the ChatGPT desktop app, ask for current information in a chat. ChatGPT records search activity with the other tool calls in the transcript. In ChatGPT web, ask for current information or sources. Search results and citations appear in the chat when ChatGPT uses web search. Workspace settings can limit whether search is available. In the CLI, pass `--search` to fetch live results for one run: `codex --search "Summarize the latest release notes for this dependency"` Searches appear as `web_search` items in the interactive transcript and in `codex exec --json` output. In the IDE extension, ask Codex to search while you work in the editor. The extension uses the connected Codex host’s search mode. Search activity appears in the chat transcript. ## Configure local web search For local Codex chats, Codex enables cached search by default. Cached mode uses an OpenAI-maintained index instead of fetching arbitrary pages live, which lowers—but doesn’t remove—prompt injection risk. Web search is a hosted tool, separate from sandboxed local command networking. It does not use the permission profile’s network proxy or domain allowlist, and it can remain available when command network access is disabled. Configure search with `web_search`, `tools.web_search.allowed_domains`, and managed `allowed_web_search_modes` as appropriate. Search-domain filters do not restrict local command traffic, apps, connectors, or MCP servers. Use live search when your task depends on the latest information. Set `web_search = "live"` in `config.toml`. Set `web_search = "disabled"` to turn the tool off. The `"indexed"` mode permits external web access only when the search index gates the request. When Codex runs with full access, web search defaults to live results. See [Config basics](https://developers.openai.com/codex/config-file/config-basic) for config file locations and precedence. ### Search with a custom model provider A custom model provider can opt in to standalone web search when it supports a compatible search endpoint: ``` model_provider = "custom" web_search = "live" [model_providers.custom] name = "Custom Responses provider" base_url = "https://example.com/v1" env_key = "CUSTOM_RESPONSES_API_KEY" supports_standalone_web_search = true ``` Custom providers default to `supports_standalone_web_search = false`. Standalone web search remains under development and is off by default. Setting this provider capability doesn’t enable the feature: the provider, selected model, and runtime must also support standalone search. Workspace and managed search restrictions still apply. For network boundaries that apply to Codex cloud environments, see [Internet access](https://developers.openai.com/codex/cloud/internet-access).
