The same approach can work when you self-host n8n on your own server.<\/p>\n\n\n\n<h2 id=\"h-how-to-connect-n8n-to-multiple-ai-models\" class=\"wp-block-heading\">How to connect n8n to multiple AI models?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">You can connect n8n to multiple AI models by configuring an OpenAI-compatible connection to use a gateway endpoint. The gateway then provides access to supported models through one API key and Base URL.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/docs.n8n.io\/integrations\/builtin\/credentials\/openai\/\" rel=\"noopener noreferrer\" target=\"_blank\">OpenAI credential in n8n<\/a> includes an API key and Base URL. When an AI gateway supports the required OpenAI-compatible API format, you can point this connection to the gateway instead of connecting directly to OpenAI.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can then select supported models using the exact model IDs exposed by that gateway.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Compatibility can vary by model, gateway and n8n feature. A successful credential connection does not always guarantee that every model or capability will work with every node, so test individual workflow steps before using them in production.<\/p>\n\n\n\n<h2 id=\"h-why-separate-api-keys-for-every-model-break-n8n-workflows\" class=\"wp-block-heading\">Why separate API keys for every model break n8n workflows?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Most AI applications do not necessarily stay with one model or provider.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/vercel.com\/state-of-ai\" rel=\"noopener noreferrer\" target=\"_blank\">Vercel&#8217;s State of AI survey<\/a> of 656 AI application builders found that respondents maintained relationships with two providers on average. The survey also found that 64% used two or more models in production.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Every additional provider can introduce another:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Account to manage<\/li>\n\n\n\n<li>API key to store and rotate<\/li>\n\n\n\n<li>Billing relationship to track<\/li>\n\n\n\n<li>Provider integration to configure<\/li>\n\n\n\n<li>Set of model names and capabilities to monitor<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In n8n, those differences can spread credentials and configuration across multiple workflows.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A gateway can reduce that overhead by putting supported providers behind one compatible API endpoint. Your workflow can then keep the same connection while you choose different supported models for different steps.<\/p>\n\n\n\n<h2 id=\"h-how-n8n-reaches-any-model-through-one-credential\" class=\"wp-block-heading\">How n8n reaches any model through one credential?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When you use an OpenAI-compatible connection in n8n, the credential contains two important values: your API key and the Base URL.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">By default, an OpenAI connection points to OpenAI&#8217;s API. With a compatible gateway, you can instead configure the Base URL to point to the gateway endpoint.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The gateway sits between your workflow and supported AI providers. It accepts a compatible request, identifies the model being requested and sends the request to the appropriate provider.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An OpenAI-compatible endpoint can come from:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>An AI provider<\/li>\n\n\n\n<li>A managed AI gateway<\/li>\n\n\n\n<li>A compatible proxy or bridge you run yourself<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This does not mean every n8n AI integration uses the OpenAI protocol. n8n also provides dedicated integrations and credentials for individual providers. The gateway approach is specifically useful when you want compatible models available through a consolidated connection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you are building agents rather than individual AI calls, see our guide on how to <a href=\"https:\/\/www.bluehost.com\/blog\/how-to-build-an-ai-agent-with-n8n\/\">build an AI agent with n8n<\/a>.<\/p>\n\n\n\n<h2 id=\"h-three-ways-to-connect-multiple-ai-models-in-n8n\" class=\"wp-block-heading\">Three ways to connect multiple AI models in n8n<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There are three common approaches to multi-model access. The right option depends on how much infrastructure you want to manage and how much control you need.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Approach<\/th><th>Accounts to manage<\/th><th>n8n credentials<\/th><th>Switch models<\/th><th>Routing or failover<\/th><th>Best for<\/th><\/tr><\/thead><tbody><tr><td>Native provider integrations<\/td><td>One per provider<\/td><td>Usually one per provider<\/td><td>Configure the relevant provider node<\/td><td>Build into the workflow<\/td><td>Teams using one or two providers<\/td><\/tr><tr><td>OpenAI-compatible gateway<\/td><td>One gateway relationship<\/td><td>One or more gateway credentials<\/td><td>Change the supported model ID<\/td><td>Workflow or gateway level<\/td><td>Multi-model workflows<\/td><\/tr><tr><td>Self-built compatible bridge<\/td><td>Depends on your architecture<\/td><td>One connection to the bridge<\/td><td>Change the supported model ID<\/td><td>Build your own logic<\/td><td>Teams needing custom control<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\">\n<p class=\"wp-block-paragraph\">For many multi-model workflows, a managed gateway reduces the number of connections you need to maintain while keeping model choice flexible.<\/p>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">If you plan to host your own automation stack, our guide to <a href=\"https:\/\/www.bluehost.com\/blog\/vps-ai-llm-guide\/\">deploying AI on a VPS<\/a> covers the infrastructure side.<\/p>\n\n\n\n<h3 id=\"h-1-native-per-provider-nodes\" class=\"wp-block-heading\">1. Native per-provider nodes<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">n8n includes integrations and credentials for major AI providers. This approach can work well when you rely on one or two providers and want access to provider-specific configuration or capabilities directly within n8n.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The trade-off is additional setup as your provider count grows. Each provider can require a separate account, credential, integration and billing relationship.<\/p>\n\n\n\n<h3 id=\"h-2-an-openai-compatible-gateway\" class=\"wp-block-heading\">2. An OpenAI-compatible gateway<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A gateway places supported providers behind one compatible endpoint. With <a href=\"https:\/\/www.bluehost.com\/ai-gateway\">Bluehost AI Gateway<\/a>, you can create an API key that eligible applications can use to access supported AI models through the Gateway.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead of maintaining individual provider accounts and API credentials, you use Bluehost AI Credits for supported model requests.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can choose which supported model a workflow step calls using the model ID exposed by the Gateway. You can also create multiple Gateway API keys if you want to separate applications, integrations or usage tracking.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This approach works well for teams that regularly test or switch between AI models without wanting to rebuild provider connections each time.<\/p>\n\n\n\n<h3 id=\"h-3-a-self-built-openai-compatible-bridge\" class=\"wp-block-heading\">3. A self-built OpenAI-compatible bridge<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You can also build and run your own proxy or bridge that accepts compatible requests and forwards them to selected AI providers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This gives you greater control over areas such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Routing<\/li>\n\n\n\n<li>Logging<\/li>\n\n\n\n<li>Authentication<\/li>\n\n\n\n<li>Request transformation<\/li>\n\n\n\n<li>Provider selection<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">However, you are also responsible for security, uptime, maintenance and provider compatibility.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A self-built bridge makes the most sense when your application needs routing or transformation behavior that a managed gateway does not provide.<\/p>\n\n\n\n<h2 id=\"h-how-to-add-one-key-to-an-n8n-ai-node\" class=\"wp-block-heading\">How to add one key to an n8n AI node?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">These steps assume you already have n8n running and are familiar with its credential settings. The goal is to create a reusable connection that can reach models supported by your gateway.<\/p>\n\n\n\n<h3 id=\"h-step-1-create-an-api-key\" class=\"wp-block-heading\">Step 1: Create an API key<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>With Bluehost AI Gateway, first add AI Credits and then <a href=\"https:\/\/www.bluehost.com\/help\/article\/bh-manage-and-create-api-keys\">create and manage API keys<\/a> from the AI Tooling section of your Bluehost VPS or <a href=\"https:\/\/www.bluehost.com\/vds-hosting\">Virtual Dedicated Server Hosting (VDS)<\/a> panel.<\/li>\n\n\n\n<li>You can use one key across eligible workflows or create additional keys when you want to separate applications or make access easier to track and revoke.<\/li>\n<\/ul>\n\n\n\n<h3 id=\"h-step-2-create-an-openai-compatible-connection\" class=\"wp-block-heading\">Step 2: Create an OpenAI-compatible connection<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In n8n, create an OpenAI credential and add the API key provided by your gateway. <\/li>\n\n\n\n<li>Set the Base URL to the endpoint provided by the gateway rather than the default OpenAI endpoint.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The exact credential interface can vary by n8n version, so check the documentation for the version you are using.<\/p>\n\n\n\n<h3 id=\"h-step-3-connect-the-credential-to-your-ai-workflow\" class=\"wp-block-heading\">Step 3: Connect the credential to your AI workflow<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Add an applicable OpenAI-compatible AI node or connect an OpenAI Chat Model sub-node to an AI Agent workflow when that configuration fits your use case.<\/li>\n\n\n\n<li>Select the gateway credential you created. This lets compatible workflow steps reuse the same gateway connection rather than requiring separate credentials for every supported provider.<\/li>\n<\/ul>\n\n\n\n<h3 id=\"h-step-4-choose-a-supported-model-id\" class=\"wp-block-heading\">Step 4: Choose a supported model ID<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Select the model using the exact model ID exposed by your gateway.<\/li>\n\n\n\n<li>Do not assume that a model&#8217;s public product name is the same as its API ID. Model IDs can vary by provider and gateway.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For example, an OpenAI-compatible client follows this general pattern:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>&lt;pre>&lt;code>from openai import OpenAI\n\nclient = OpenAI(\n    api_key=\"YOUR_GATEWAY_KEY\",\n    base_url=\"YOUR_GATEWAY_BASE_URL\"\n)\n\nresponse = client.chat.completions.create(\n    model=\"YOUR_MODEL_ID\",\n    messages=&#91;\n        {\n            \"role\": \"user\",\n            \"content\": \"Summarize this support ticket.\"\n        }\n    ]\n)\n&lt;\/code>&lt;\/pre><\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Use the Base URL and exact model ID provided by your gateway.<\/p>\n\n\n\n<h3 id=\"h-step-5-test-the-model-response\" class=\"wp-block-heading\">Step 5: Test the model response<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Run the AI step with a small test input.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Confirm that:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The request completes successfully<\/li>\n\n\n\n<li>The expected model responds<\/li>\n\n\n\n<li>The response format works with downstream steps<\/li>\n\n\n\n<li>Usage is recorded as expected<\/li>\n<\/ul>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Pro tip:<\/strong> Test each AI step independently before connecting it to the rest of your automation. This makes model ID, endpoint and compatibility problems easier to identify.<\/p>\n<\/blockquote>\n\n\n\n<h2 id=\"h-how-to-switch-ai-models-without-rebuilding-your-n8n-workflow\" class=\"wp-block-heading\">How to switch AI models without rebuilding your n8n workflow?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Once compatible models are available through the same gateway connection, changing models can become much simpler.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead of creating another provider credential, you can select a different model ID supported by your gateway.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, you might use:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A faster or lower-cost model for classification<\/li>\n\n\n\n<li>Another model for information extraction<\/li>\n\n\n\n<li>A stronger model for complex reasoning<\/li>\n\n\n\n<li>A different model for final content generation<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Consider a support workflow that processes a large number of tickets.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You could use one model to classify incoming requests, then send only complex cases to another model for a more detailed response.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The gateway connection remains the same. You change the model used by the relevant AI step.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before choosing models for each task, you can <a href=\"https:\/\/www.bluehost.com\/blog\/best-ai-models\/\">compare leading AI models<\/a> based on capabilities and cost.<\/p>\n\n\n\n<h2 id=\"h-how-to-add-failover-and-routing-across-ai-models\" class=\"wp-block-heading\">How to add failover and routing across AI models?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Multi-model access can also help you design more resilient workflows.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If a primary model request fails, you can configure your n8n workflow to handle the error and direct the request to another compatible model.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The exact implementation depends on your n8n workflow and node configuration. In general, you can use workflow error-handling and branching logic to decide when another AI step should run.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Send the request to your primary model.<\/li>\n\n\n\n<li>Detect whether the step completed successfully.<\/li>\n\n\n\n<li>Route failed requests through an alternative workflow path.<\/li>\n\n\n\n<li>Call another compatible model.<\/li>\n\n\n\n<li>Continue processing the successful response.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Keep fallback models appropriate for the original task. A text-generation step should fall back to another model capable of handling the same type of request.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some gateways can also support routing decisions outside the n8n workflow. In that architecture, the gateway handles part of the provider-selection logic while n8n keeps a simpler workflow.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For larger automation environments, our guide to <a href=\"https:\/\/www.bluehost.com\/blog\/n8n-ai-agent-workflows\/\">scaling n8n automation workflows<\/a> covers additional considerations.<\/p>\n\n\n\n<h2 id=\"h-how-to-keep-ai-cost-governance-and-data-under-control\" class=\"wp-block-heading\">How to keep AI cost, governance and data under control?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Multi-model workflows introduce operational considerations beyond simply connecting to the models.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the Stack Overflow 2025 Developer Survey, among developers using AI agents, <a href=\"https:\/\/survey.stackoverflow.co\/2025\/ai\" rel=\"noopener noreferrer\" target=\"_blank\">cost and accuracy were among the concerns reported by respondents<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A few controls can help as your workflows grow:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Protect credentials server-side:<\/strong> Store API keys in n8n credentials or another protected server-side secret store. Do not expose them in prompts or client-side applications.<\/li>\n\n\n\n<li><strong>Track usage by workflow and model:<\/strong> Record which workflow and model generated each request when you need more detailed usage visibility.<\/li>\n\n\n\n<li><strong>Use approved model IDs:<\/strong> Maintain a list of models your team has reviewed for production workflows.<\/li>\n\n\n\n<li><strong>Control retries:<\/strong> Limit retry attempts and use backoff when requests encounter rate limits or temporary failures.<\/li>\n\n\n\n<li><strong>Handle generated files carefully:<\/strong> If a provider returns temporary or signed media URLs, store files appropriately before those links expire.<\/li>\n\n\n\n<li><strong>Maintain useful logs:<\/strong> Record enough information about model selection and workflow outcomes to troubleshoot failures and review automation behavior.<\/li>\n\n\n\n<li><strong>Review provider terms:<\/strong> Check rate limits, data handling terms and other usage requirements before relying on any model for production workloads.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A prepaid credit system can also simplify billing by consolidating supported AI usage into one balance rather than requiring separate invoices from multiple model providers.<\/p>\n\n\n\n<h2 id=\"h-how-to-troubleshoot-common-multi-model-connection-errors\" class=\"wp-block-heading\">How to troubleshoot common multi-model connection errors?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Most connection problems come from a few common configuration issues.<\/p>\n\n\n\n<h3 id=\"h-1-incorrect-base-url\" class=\"wp-block-heading\">1.
