Anthropic Claude models

Claude models excel at analysis, summarization, and following detailed instructions.

​
Claude Haiku 4.5

Model ID: anthropic.claude-haiku-4.5 The fastest Claude model, optimized for high-throughput tasks where speed matters more than deep analysis. Best for:
  • Simple classification tasks
  • Data extraction
  • Quick summaries
  • High-volume processing
Official documentation: Claude Haiku

​
Claude Sonnet 4.5

Model ID: anthropic.claude-sonnet-4.5 A balanced model offering strong performance across most tasks with good efficiency. Best for:
  • Content analysis
  • Code generation
  • Multi-step reasoning
  • General-purpose tasks
Official documentation: Claude Sonnet

​
Claude Opus 4.5

Model ID: anthropic.claude-opus-4.5 The most capable Claude model for complex tasks requiring deep analysis and nuanced understanding. Best for:
  • Complex reasoning chains
  • Nuanced analysis
  • Research tasks
  • High-stakes decisions
Official documentation: Claude Opus

​
OpenAI models

OpenAI models offer strong reasoning capabilities and broad knowledge.

​
GPT-4.1

Model ID: openai.gpt-4.1 Advanced reasoning model with strong analytical capabilities. Best for:
  • Complex analysis
  • Technical reasoning
  • Multi-domain tasks
Official documentation: GPT-4 Models

​
o4-mini

Model ID: openai.o4-mini Smaller, faster model optimized for efficiency. Best for:
  • Quick responses
  • Simple tasks
  • Cost-sensitive applications
Official documentation: OpenAI Models

​
GPT-oss-120b

Model ID: openai.gpt-oss-120b Open-source large language model with broad capabilities. Best for:
  • General-purpose tasks
  • Open-source requirements

Usage example

import { NarrativeApi } from '@narrative.io/data-collaboration-sdk-ts';

const api = new NarrativeApi({
  apiKey: process.env.NARRATIVE_API_KEY,
});

// Use Claude Sonnet for balanced performance
const job = await api.runModelInference({
  data_plane_id: 'dp_your_data_plane_id',
  model: 'anthropic.claude-sonnet-4.5',
  messages: [
    { role: 'user', text: 'Analyze this dataset...' }
  ],
  inference_config: {
    output_format_schema: {
      type: 'object',
      properties: {
        analysis: { type: 'string' }
      },
      required: ['analysis']
    }
  }
});
