const server = new OwlLayerServer({
  llm: new AnthropicAdapter({
    apiKey: process.env.ANTHROPIC_API_KEY!,
    model: ANTHROPIC_DEFAULT_MODEL,
    systemPrompt: 'You are an intelligent agent embedded in the application.',

Model catalog

This package exports a typed catalog of Claude models so you can configure AnthropicAdapter from an autocompleted constant instead of copying a long identifier. Any string is still accepted (unlisted identifiers are sent to the provider unchanged); the constants are recommended.

• ANTHROPIC_MODELS (AnthropicModel): the current lineup and every legacy-available Claude model, each with its readable name and role.
• ANTHROPIC_DEFAULT_MODEL: 'claude-sonnet-5', unchanged while it stays Active on Anthropic's model-status page.
• ANTHROPIC_LANGUAGES: ['multilingual'] — Anthropic does not publish a language code list; anthropicSupportsLanguage(id, language) always reports every language as supported.
• isKnownAnthropicModel(id): reports whether an identifier is listed, without ever throwing.
• ANTHROPIC_DEPRECATED_MODELS / getAnthropicDeprecatedModel(id): models Anthropic has deprecated or retired. Constructing AnthropicAdapter with one of them — as a constant or as a free string — logs one warning naming the replacement; the configured value is still used.
• ANTHROPIC_CATALOG_VERIFIED_AT: the date the catalog was last checked against Anthropic's official documentation.
