AI API Cost per Request: Quick Reference Table
How much does a single API call actually cost? We calculated it for all 88 models across 10 providers at four common request sizes. Now with batch API pricing. Bookmark this page.
Assumption: Each request sends 3x more input tokens than output tokens (typical for chat, RAG, and code assistant workloads). Costs are per single request. All prices verified Jul 9, 2026. Batch mode shows 50% discounted rates for providers with batch APIs (OpenAI, Anthropic, Google) — batch jobs process within 24 hours. Streaming mode adds 15% overhead to account for SSE framing and repeated context tokens in streamed responses.
All 59 Models — Cost per Request
Sorted cheapest to most expensive. At 1K tokens, costs range from $0.000100 (Llama 3.1 8B) to $0.067500 (GPT-5.5 Pro) — a 675x gap.

Key Takeaways
The 675x Gap
The cheapest model (Llama 3.1 8B at $0.000100/request) costs 675x less than the most expensive (GPT-5.5 Pro at $0.067500/request) for a 1K-token request. At 5K tokens, the gap holds at 675x.
- For high-volume chatbots: Llama 3.1 8B, GPT-oss 20B, or DeepSeek V4 Flash — all under $0.0002 per 1K-token request
- For production code assistants: GPT-4o or Claude Sonnet 4.6 — $0.004–$0.006 per request with strong reasoning
- For complex research: Claude 4 Opus or GPT-5 — $0.015–$0.03 per request, but best-in-class quality
- Best value in mid-tier: Llama 3.3 70B at $0.00104/request — 4x cheaper than GPT-4o with comparable quality
- Hidden winner: DeepSeek V4 Pro at $0.00055/request — mid-tier quality at budget prices (75% discount through Jul 2026)

These costs assume a 3:1 input-to-output token ratio. Your actual costs depend on your specific workload:
- Chatbots: Usually 2:1 to 4:1 ratio — this table is accurate
- Code generation: Often 1:3 or higher — output-heavy, so multiply output costs
- Document analysis: Often 10:1 or higher — input-heavy, costs are lower than shown
- RAG pipelines: Usually 5:1 — input-heavy with retrieved context
