Guide for using the Anthropic Go SDK to retrieve information about a specific model or resolve a model alias to a model ID.

Insight

The Models.Get method retrieves a specific model by ID or alias using the endpoint GET /v1/models/{model_id}. The method signature is client.Models.Get(ctx, modelID, query) (*ModelInfo, error). The modelID parameter accepts either a model identifier string or an alias. The optional ModelGetParams query parameter includes Betas field (param.Field[[]AnthropicBeta]) to specify beta versions. Available beta constants include: AnthropicBetaMessageBatches2024_09_24, AnthropicBetaPromptCaching2024_07_31, AnthropicBetaComputerUse2024_10_22, AnthropicBetaComputerUse2025_01_24, AnthropicBetaPDFs2024_09_25, AnthropicBetaTokenCounting2024_11_01, AnthropicBetaTokenEfficientTools2025_02_19, AnthropicBetaOutput128k2025_02_19, AnthropicBetaFilesAPI2025_04_14, AnthropicBetaMCPClient2025_04_04, AnthropicBetaMCPClient2025_11_20, AnthropicBetaDevFullThinking2025_05_14, AnthropicBetaInterleavedThinking2025_05_14, AnthropicBetaCodeExecution2025_05_22, AnthropicBetaExtendedCacheTTL2025_04_11, AnthropicBetaContext1m2025_08_07, AnthropicBetaContextManagement2025_06_27, AnthropicBetaModelContextWindowExceeded2025_08_26, AnthropicBetaSkills2025_10_02, AnthropicBetaFastMode2026_02_01, AnthropicBetaOutput300k2026_03_24, AnthropicBetaUserProfiles2026_03_24, AnthropicBetaAdvisorTool2026_03_01, and AnthropicBetaManagedAgents2026_04_01. The returned ModelInfo struct contains: ID (string), Capabilities (ModelCapabilities with Batch, Citations, CodeExecution, ContextManagement, Effort, ImageInput, PDFInput, StructuredOutputs, and Thinking support), CreatedAt (RFC 3339 datetime), DisplayName (human-readable name), MaxInputTokens (int64), MaxTokens (int64), and Type (constant ModelModel = “model”).

Hành động

Initialize the client with option.WithAPIKey(“your-api-key”), then call client.Models.Get with context, model ID string, and empty or populated ModelGetParams struct. Handle the returned ModelInfo and error. Example usage: modelInfo, err := client.Models.Get(context.TODO(), “model_id”, anthropic.ModelGetParams{}). The modelInfo response can determine model capabilities, resolve aliases, and get metadata like max tokens and supported features.

Kết quả

Returns a ModelInfo struct containing the model ID, capability information (including batch support, citations, code execution, context management strategies, effort levels, thinking types), creation timestamp, display name, input/output token limits, and object type. Returns error if the model is not found or request fails.
