What is the cheapest AI API for e-commerce?

Gemini 2.0 Flash Lite at $0.075/$0.30 per 1M tokens is the cheapest for basic e-commerce tasks like generating product descriptions. For chatbots that need reliable conversations, DeepSeek V4 Flash ($0.14/$0.28) or GPT-4o mini ($0.15/$0.60) offer better quality. Generating 1,000 product descriptions/day costs $0.50-$3/month depending on the model.

How much does AI cost for an e-commerce store?

For a mid-size store: product descriptions (1,000/day) ~$1-3/month, customer chatbot (5,000 conversations/day) ~$5-15/month, review analysis (10,000 reviews/day) ~$1-3/month. Total AI cost: $10-25/month for a store with 10K+ SKUs. Budget models handle most tasks; reserve premium models for complex customer inquiries or high-stakes product copy.

Can AI write good product descriptions?

Yes, modern LLMs generate compelling product descriptions from specs, features, and images. For bulk generation (1000+ SKUs), use budget models like Gemini Flash or DeepSeek — they produce 80% of the quality at 10% of the cost. For hero products or premium brands, use Claude Sonnet or GPT-5 for copy that matches your brand voice. Always have a human review critical product pages.

Strategy: E-Commerce AI Routing

E-commerce has diverse AI needs — product copy, customer support, reviews, personalization. Each has different quality requirements. Route by task type, not volume.

Smart Routing (1K tasks/day mixed workload)

Routine (60%): product tags, categories, meta descriptions → Gemini Flash$3.24/mo

Conversational (30%): chatbot, email replies, Q&A → DeepSeek V4 Flash$2.27/mo

Premium (10%): hero product copy, complex support → Claude Sonnet$5.40/mo

Total with routing$10.91/mo (vs $54 on Claude Sonnet for all)

This routing approach saves 80% compared to running everything through Claude Sonnet. The key insight: most e-commerce tasks are routine and don't need premium models.

E-Commerce-Specific Considerations

Product descriptions are output-heavy: Unlike analysis tasks, product generation produces more output than input. Output price matters more than input price.
Chatbot conversations accumulate context: A 10-message customer conversation builds up 10K+ tokens of context. Models with large context windows handle this better.
Batch for catalog updates: Product description generation doesn't need real-time. Batch APIs save 50%+ for bulk catalog operations.
Personalization at scale: Recommendation prompts need to run per-user. At 100K users/day, even cheap models add up — use embeddings for pre-computed personalization instead.
Multi-language support: For international stores, models with strong multilingual capabilities (Gemini, GPT-4o) reduce translation costs by handling product copy in multiple languages natively.
