AI providers and model configuration

​

Overview

FlowX supports configuring AI providers at three levels:

• Organization level: Add and manage AI providers, set API keys, whitelist specific models
• Organization level (per workspace type): Assign default and fallback models for each AI capability, scoped by workspace type (Sandbox, Staging, Production)
• Node level: Override the default model on individual workflow nodes

Organization admins define which providers and models are available, and configure model assignments per workspace type. Workflow designers can optionally override the model on individual AI nodes.

---

​

Organization-level: Model providers

Access model providers from Organization Settings → AI Settings → Model Providers. An OpenAI provider card is present by default, using a FlowX-managed key. You can switch it to your own key or add additional providers.

​

Adding a provider

​

API Key Source

The API Key Source radio buttons control how the provider authenticates: When editing the OpenAI provider, switch between Own and FlowX under API Key Source.

​

Model whitelisting

The model whitelisting modal (opened from Manage Models) lets you control which discovered models are available downstream. Models are grouped by capability: Each model row shows: model name, capability badges, context window (e.g., “128K tokens”), and indicative pricing (e.g., “$5 /$15 per 1M tokens”).

• Use Search to filter models by name
• Use Select All / Deselect All for bulk actions
• A counter at the bottom shows “X of Y models enabled”
• Click Save Whitelist to persist your selection

​

Editing a provider

When editing an existing provider (API key or Organization ID changed):

1. The Save button is disabled after any field edit
2. Click Test Connection to validate the new credentials
3. On success, Save becomes enabled
4. If the newly discovered model list differs from the previous one:
   • New models are added to the whitelist automatically
   • If any previously enabled models are no longer available, a replacement wizard guides you through selecting alternatives
   • Skipping the wizard removes the missing models from all dropdowns where they were used, and the fallback mechanism activates

​

Deleting a provider

All providers except the default OpenAI (FlowX-managed) can be deleted. Deleting a provider:

1. Shows a confirmation with the impact: nodes and knowledge bases using this provider’s models switch to their fallback model
2. If the fallback model is also from the deleted provider, a warning indicates that all LLM-related activities using those models will fail

​

Provider card

Each provider card shows:

• Provider name and icon
• Masked API key (last 4 characters visible, e.g., ••••••••••••1234)
• Model count: “Models enabled: X / Y”
• Organization ID (if configured)
• Connection status
• Available actions: Manage Models, Edit, Delete

​

Defaults & Fallbacks

Access model assignments from Organization Settings → AI Settings → Defaults & Fallbacks. Organization admins assign a Default Model and an optional Fallback Model for each AI capability, scoped by workspace type. Use the Sandbox, Staging, and Production tabs to configure different model assignments per environment. Select Use provider default to inherit the catalog default for that capability. Default models from the OpenAI FlowX key are pre-assigned for each capability.

​

Assigning models

For each capability:

1. Select a Default model from org-whitelisted models matching that capability, or use the provider default
2. Optionally select a Fallback model, used if the default model is unavailable or rate-limited

Assignments are configured per workspace type (Sandbox, Staging, Production). All workspaces of a given type inherit the same model assignments.

---

​

Fallback behavior

When a primary model is unavailable, rate-limited, or disabled at the organization level, the system automatically switches to the configured fallback model. The resolution order is:

1. Node-level override (if configured) → its fallback model
2. Workspace default → its fallback model
3. Error if all options exhausted

---

​

Per-node model override

Workflow designers can override the default model on individual AI nodes (Custom Agent, Intent Classification, etc.) in the Integration Designer. This allows different nodes in the same workflow to use different models. For example, a fast model for intent classification and a more capable model for complex reasoning.

​

How it works

When configuring an AI node, an optional Model Override section lets you select a specific model: The override uses portable identifiers (providerType + modelIdStr) that resolve at runtime against the organization’s available models. Only models enabled in the organization’s whitelist can be selected. When no override is set, the node uses the workspace default model for its capability (text generation, embeddings, etc.).

​

Supported providers

FlowX maintains a provider catalog with pre-configured provider types. Each provider type includes display metadata (name, icon) and optional base URL presets. SaaS · Mistral is also available as a BYOK provider: add it with your own Mistral API key, then enable models from the seeded catalog. Mistral models cover chat, image understanding, embeddings, and document OCR (the Mistral Large, Medium, Small, Magistral, Codestral, Pixtral, OCR, and Embed lines).
