Claude 3 Haiku – speed above all
Haiku is Claude’s model optimised for speed. Responses are instant, quality is good (though lower than Sonnet). Ideal when responsiveness is the priority.
When to choose:
– High-volume chatbot (thousands of conversations daily)
– Simple FAQs, opening hours, basic support
– When response speed matters more than thoroughness
Practical comparison for 3 business types
Online store (e-commerce):
Recommendation: GPT-4o Mini. Fast, precise, excellent for questions about products, delivery, returns.
SaaS company with technical documentation:
Recommendation: Claude 3.5 Sonnet. Better handles long API docs, instructions, troubleshooting.
Financial or legal startup:
Recommendation: GPT-4o or Claude 3.5 Sonnet. Both excel at complex questions requiring precision.
You can change the model at any time
In AIGoChat, changing the AI model is a single click in chatbot settings – with no downtime. It’s worth testing several models on the same set of test questions and comparing answer quality for your specific use case.
Summary
There’s no one “best” model – there’s the best model for your case. Start with GPT-4o Mini (default), monitor answer quality for a week, and switch to a more advanced model if you see gaps. All API costs are included in the AIGoChat subscription – you don’t pay separately for tokens.
