AI API Pricing Comparison: Official vs aiapi.cheap (2026)

Side-by-side cost comparison across Claude, GPT, Gemini, Grok, and DeepSeek — see how much you save with aiapi.cheap on the Pro plan (80% off).

The Real Cost of AI APIs in 2026

Five frontier vendors. Five pricing pages. Five separate invoices. If you're touching more than one model, the bill snowballs fast — especially in production.

aiapi.cheap proxies all five vendors behind one key at 70-80% off list price. Same model IDs, same SDK shape, same streaming. Only your invoice changes.

Below are concrete savings on the Pro plan ($19 lifetime, 80% off).

Claude (Anthropic)

| Model | Official input / 1M | Pro input / 1M | Official output / 1M | Pro output / 1M |

|---|---|---|---|---|

| Opus 4.7 | $5.00 | $1.00 | $25.00 | $5.00 |

| Sonnet 4.6 | $3.00 | $0.60 | $15.00 | $3.00 |

| Haiku 4.5 | $1.00 | $0.20 | $5.00 | $1.00 |

For a typical Sonnet production app (1K input, 2K output):

  • Official: $0.033 per request
  • Pro: $0.0066 per request
  • At 10,000 req/day: save ~$7,920/month
  • GPT (OpenAI)

    | Model | Official input / 1M | Pro input / 1M | Official output / 1M | Pro output / 1M |

    |---|---|---|---|---|

    | GPT-4o | $2.50 | $0.50 | $10.00 | $2.00 |

    | GPT-4o mini | $0.15 | $0.03 | $0.60 | $0.12 |

    GPT-4o at 5K req/day (500 input, 1K output) drops from $60/day to $12/day — savings ~$1,440/month.

    Gemini (Google)

    | Model | Official input / 1M | Pro input / 1M | Official output / 1M | Pro output / 1M |

    |---|---|---|---|---|

    | Gemini 2.5 Pro | $1.25 | $0.25 | $5.00 | $1.00 |

    | Gemini 2.5 Flash | $0.075 | $0.015 | $0.30 | $0.06 |

    Gemini Flash is already cheap — but at high volume (50K req/day), savings still add up to roughly $300/month.

    Grok (xAI)

    | Model | Official input / 1M | Pro input / 1M | Official output / 1M | Pro output / 1M |

    |---|---|---|---|---|

    | Grok 2 | $2.00 | $0.40 | $10.00 | $2.00 |

    DeepSeek

    | Model | Official input / 1M | Pro input / 1M | Official output / 1M | Pro output / 1M |

    |---|---|---|---|---|

    | DeepSeek V3 | $0.27 | $0.054 | $1.10 | $0.22 |

    DeepSeek is the budget-tier baseline — if you're already on DeepSeek for cost reasons, the proxy still cuts your spend by 80%.

    Two Plans, Five Vendors

    No per-seat math. No hidden tiers. Just two options:

  • Basic — free forever, 70% off across all five vendors, community support
  • Pro — $19 lifetime (one-time), 80% off, priority support
  • The Pro plan pays for itself after ~$24 of vendor-direct usage — a few days of hobbyist work or one afternoon of production traffic.

    Same APIs, No Compromises

    We pass requests through to the real vendor APIs. Same models, same quality, same context window, same streaming, same prompt-caching. Anthropic-format SDK calls hit /v1/messages; OpenAI-compatible calls (universal across all 5 vendors) hit /v1/chat/completions. The only thing different is the price.
