Comparison by Use Case
Customer-Facing Chatbot
This is where model quality matters most — visitors judge your business by how the chatbot responds.
| Model | Rating | Why |
|---|---|---|
| Claude 3.5 Sonnet | ⭐⭐⭐⭐⭐ | Best at natural, nuanced conversation. Follows complex instructions precisely. Excellent at staying in character. |
| GPT-4o | ⭐⭐⭐⭐⭐ | Equally strong. Slightly better at factual accuracy. Widely tested in customer-facing deployments. |
| Claude 3 Haiku | ⭐⭐⭐⭐ | Good quality at much lower cost. Ideal for high-volume chatbots where cost matters. |
| GPT-4o mini | ⭐⭐⭐⭐ | Fast and affordable. Noticeably less capable than GPT-4o but fine for simple FAQ bots. |
| DeepSeek-Chat | ⭐⭐⭐ | Capable but occasionally awkward phrasing in English. Good for budget-sensitive deployments. |
Recommendation: Claude 3.5 Sonnet or GPT-4o for quality-first chatbots. Claude 3 Haiku for cost-efficient chatbots at scale.
Blog Article Generation
| Model | Rating | Why |
|---|---|---|
| GPT-4o | ⭐⭐⭐⭐⭐ | Excellent structure, good keyword integration, natural flow. Industry standard for content. |
| Claude 3.5 Sonnet | ⭐⭐⭐⭐⭐ | Particularly strong at nuanced, long-form writing. Less likely to produce generic-sounding content. |
| DeepSeek-Chat | ⭐⭐⭐⭐ | Surprisingly good quality at ~20× lower cost than GPT-4o. Best value for bulk content generation. |
| Gemini 1.5 Pro | ⭐⭐⭐⭐ | Good quality, especially for topical authority content. Strong for research-heavy articles. |
Recommendation: GPT-4o or Claude for quality flagship content. DeepSeek-Chat for bulk generation where cost-per-article matters.
WooCommerce Product Descriptions (Bulk)
| Model | Rating | Why |
|---|---|---|
| DeepSeek-Chat | ⭐⭐⭐⭐⭐ | Best cost-quality ratio for repetitive structured tasks. 500 descriptions costs ~$0.50–2 total. |
| GPT-4o mini | ⭐⭐⭐⭐⭐ | Fast, cheap, reliable for structured output. Good at following format templates consistently. |
| Gemini 1.5 Flash | ⭐⭐⭐⭐ | Very affordable. Good at following structured templates for product copy. |
Recommendation: DeepSeek-Chat or GPT-4o mini. Don’t use GPT-4o for bulk product descriptions — the cost difference is enormous with minimal quality gain.
AI Training / Embeddings
For generating embeddings (training your chatbot), only some models support it. In AIWU, embeddings use a separate embedding model rather than the chat model:
- OpenAI text-embedding-3-small: Fast, cheap, high quality — recommended default
- OpenAI text-embedding-3-large: Higher accuracy for large knowledge bases
- Claude, Gemini, DeepSeek: Use OpenAI embeddings even when these are your chat provider
Cost Calculator: 10,000 Chatbot Messages/Month
Assuming average 200 tokens per exchange (question + answer):
| Model | Monthly cost estimate |
|---|---|
| GPT-4o | ~$40–60 |
| Claude 3.5 Sonnet | ~$36–54 |
| GPT-4o mini | ~$1.50–3 |
| Claude 3 Haiku | ~$3–5 |
| DeepSeek-Chat | ~$2–4 |
| Gemini 1.5 Flash | ~$1–2 |
Actual costs depend on conversation length, system prompt size, and training context.
