Building with Anthropic's Claude API
Claude 3.7 Sonnet is our default model for customer-facing AI — the best instruction following, lowest hallucination rate, and built-in safety for production applications.
How we use Anthropic Claude API
Anthropic's Claude API offers access to Claude 3.7 Sonnet (fast, highly capable, excellent safety) and Claude 3 Opus (maximum capability for complex tasks). We default to Claude for customer-facing applications where reliability matters most — Claude follows instructions more consistently than other models and is significantly less likely to produce harmful or incorrect outputs. Claude's 200K token context window also enables use cases that are impossible with shorter-context models.
What this means for your project
- ✦Production-ready Anthropic Claude API integrations, not demos
- ✦Code you own — no black boxes
- ✦Engineers who have shipped real systems with this stack
- ✦Ongoing support and updates after launch
What we build with Anthropic Claude API
Customer-facing AI chatbots
Claude reliably does what it is told and declines to do what it should not — critical for any AI touching customers directly.
Document intelligence (long documents)
Claude's 200K token window enables analysis of entire contracts, research papers, or codebases in a single prompt.
AI agents with tool use
Claude's function calling is precise and reliable — it calls the right tools with the right arguments, making it the best choice for multi-step agent systems.
Extended thinking for complex reasoning
Claude 3.7 Sonnet with extended thinking mode provides step-by-step reasoning for complex analysis, giving you visibility into how conclusions are reached.
Content moderation and classification
Claude's safety training makes it excellent at classifying sensitive content, detecting policy violations, and applying nuanced judgement in moderation tasks.
Common questions
Why choose Claude over GPT-4o?+
Claude is better for: long documents (200K vs 128K context), instruction-following reliability, safety-critical applications, and agent systems where precise tool calling is required. GPT-4o is better for speed, cost, and multimodal inputs.
Is Claude data used for training by Anthropic?+
No — API calls are not used to train Anthropic's models. Your data stays private. We use the API, not the consumer product.
