The per-provider LLM plugin settings are set in the provided AIHost/plugins/<Provider>/settings.json file. This article describes the settings. 

Prerequisites

• The SWExtension.AIExtension folder is located in your Client's swExplorerExtensions directory
• Knowledge of your organization's AI keys and services. (Note: SystemWeaver Customers integrate with the supported AI third-party services that they have access to through their own agreements or licenses. The integration and use of third-party software is at the Customer's own risk. SystemWeaver provides only the option for integration and does not assume any responsibility or liability for the use of, or the costs associated with, third-party services.)

• Top-level Fields
• ModelCapabilities[] Entries
  • Allowed enumeration values
• Cloud — Claude
• Local — Ollama, plaintext loopback

MedusaLLM discovers and initializes plugins from disk at startup (plugins/<Provider>/settings.json). There is one folder per provider (e.g., Claude, GPT, Ollama, LMStudio).

Credentials: with Llm:AcceptedCredentialSources = "Runtime" (the shipped default, Llm (router-level guards)), the APIKey field here is ignored — keys must be injected at runtime via the AIExtension <LLMApiKeys> XML (Configuring the View). Leave APIKey empty for cloud providers. Local providers (Ollama/LMStudio) typically need no key.

Top-level Fields

ModelCapabilities[] Entries

Drives model selection/routing (window fit, complexity, cost, modality).

Allowed enumeration values

The enum-typed fields accept only the values below (case-sensitive). Values are those defined in the shipped MedusaLLM assembly; Provider is not an enum — it is a free-form string matched to the plugin/provider name (e.g. Anthropic, OpenAI, Ollama, LMStudio).

SupportedInputFormats, SupportedOutputFormats and MaxComplexity are the complete enum sets. SupportedUseCases lists the values present in the shipped MedusaLLM assembly; treat it as authoritative for routing but note that the enum itself is owned by MedusaLLM and could gain members in a future package.

Cloud — Claude
