Why Do API Prices Differ 3-5x? — 6-Factor Breakdown

1. Is the 3-5x Price Gap Real?

Example: claude-opus-4-7 on Anthropic Official = $15/M output. But some relays go as low as $5-8/M. The gap = 1.5-3x. See the full comparison on the pricing page.

2. 6 Factors Explained (by Weight)

1. Cost structure (30%) — upstream official wholesale price. Anthropic official $15/M output, OpenAI $10/M, DeepSeek $2/M. The gap = upstream contract price
2. Channel markup (20%) — relays need to cover team, bandwidth, and API forwarding. A 0.5-1x markup is reasonable
3. Risk premium (20%) — IP risk, bans, exit scams, refunds. Less stable providers charge a higher premium
4. Model version (15%) — same model name, different versions (e.g., claude-3-5-sonnet vs claude-sonnet-4-5)
5. Billing model (10%) — per-token / per-request / monthly. Monthly = lowest risk
6. Promotions / subsidies (5%) — 5%-20% discounts during new-provider acquisition periods, not a normal price

3. Reading Price Gap = Risk Gap

If a provider charges $3/M while official is $15/M, a 5x price gap = a 5x risk gap. Check the reliability ranking record and 24h uptime for Lingmou AI (a representative low-price provider) before deciding whether to use it.

4. Decision Checklist

1. Cross-provider price for the same model on the pricing page = see the gap

2. Risk score on the reliability ranking = pick high coverage × low price

3. 24h service status = check stability
