Anthropic AI agent: Claude Sonnet 4 and Opus 4 with Think and Web Search tool

Claude Opus 4 is Anthropic's most advanced model for complex reasoning tasks, while Sonnet 4 balances performance and cost efficiency. Opus excels at nuanced analysis and creative tasks but costs more per token. Sonnet handles most business queries effectively at lower cost.

This workflow automatically analyzes each query to determine which model is most appropriate. For example, simple customer service FAQs would route to Sonnet, while strategic business analysis would use Opus. This ensures you get the right capability for each task without overpaying.

• Opus costs ~3x more than Sonnet per token
• Sonnet is 80% as capable for many business tasks
• Routing can be adjusted based on your priorities

The web search tool allows Claude to retrieve current information beyond its training data cutoff. When a query requires up-to-date facts, the workflow automatically triggers a search, processes the results, and incorporates them into Claude's response.

For example, if asked about today's stock prices or recent news events, Claude can fetch the latest data rather than relying solely on its knowledge. This combines Claude's reasoning with real-time information for more accurate answers to time-sensitive questions.

• Works with major search APIs like SerpAPI
• Filters and summarizes search results automatically
• Can be configured for specific trusted sources

This workflow excels at handling customer support questions, market research queries, competitive analysis, and knowledge-intensive tasks. The model selection ensures cost-effective responses for routine inquiries while applying Opus's advanced capabilities to complex strategic questions.

Common use cases include automated research assistants that can handle both simple fact-finding and deep analysis, or customer service systems that escalate complex technical issues to Opus while using Sonnet for basic FAQs. The flexibility allows adaptation to various business needs.

• Ideal for mixed-complexity query volumes
• Works well for both internal and external use
• Scales from small teams to enterprise deployments

The workflow analyzes query complexity using factors like length, technical terms, and required reasoning depth. Simple factual requests route to Sonnet, while multi-step reasoning or creative tasks use Opus. Thresholds are adjustable based on your needs.

For instance, a short question like "What's your return policy?" would go to Sonnet, while "Analyze these sales figures and suggest three growth strategies" would route to Opus. The system learns from your corrections to improve routing over time.

• Multiple complexity factors are weighted
• Routing rules can be customized
• Manual override options available

Yes, the workflow includes customizable prompt templates for different query categories. You can tailor instructions, tone, and response formats for your specific use case. The template includes examples you can modify.

For example, you might create different prompt templates for technical support versus sales inquiries, or adjust formality levels for B2B versus consumer interactions. The workflow can apply these automatically based on query analysis.

• Pre-built templates for common business uses
• Easy to add your brand voice guidelines
• Supports multi-step prompt chaining

Businesses typically see 30-50% cost reduction versus using Opus exclusively, while maintaining high-quality responses. The savings come from routing simpler queries to Sonnet, which costs about 1/3 the price of Opus per token.

For a company processing 10,000 queries monthly, this could mean saving thousands of dollars while still getting Opus-level answers for complex questions. The workflow pays for itself quickly in high-volume AI applications.

• Sonnet costs ~$0.75 per million tokens input
• Opus costs ~$3.00 per million tokens input
• Savings compound with query volume
