Choosing the large language model (LLM) that powers your AI chatbot is one of the most practical decisions you will make as a small business, agency, or founder building an AI assistant for your website. The model you pick shapes how fast your AI agent replies, how well it understands your customers, and how much it costs to run. Dante AI gives you a range of LLMs so you can match the model to the job instead of overpaying for capability you do not need.
The key trade-off is simple. Some models are built for depth and complexity and use more credits per reply. Others are open-source and free to run, so you get fast, reliable answers without touching your credit balance. This guide walks through the options so you can choose with confidence.
How to think about the choice
Before comparing individual models, weigh three questions about your use case:
- How complex are your conversations? Simple FAQs need far less horsepower than nuanced support or analysis.
- How long do they run? Long sessions and large documents benefit from a bigger context window.
- What is your budget? Free open-source models keep costs near zero; premium models cost more but reason more deeply.
