GPT-5.2 API pricing
GPT-5.2 is a model from OpenAI with a 400,000-token context window. Rates below are per 1,000,000 tokens, verified October 2026.
Price list
| Token class | Rate / 1M | Notes |
|---|---|---|
| Input | $1.75 | Prompt tokens not served from cache |
| Cached input | $0.175 | 90% below base input |
| Cache write | — | Not billed per token |
| Output | $14 | 8.0× the input rate |
| Batch API | −50% | Input and output, results within 24 h |
What GPT-5.2 costs at three real workloads
Sticker prices rarely match the invoice. These three workloads use the rates above, with cache writes charged once per job and the batch discount applied only where the provider offers it.
| Workload | Requests | Tokens | Estimated cost |
|---|---|---|---|
| Support chat | 1,000 | 4K in / 600 out | $15.40 |
| RAG with caching | 1,000 | 50K in (45K cached) / 1K out | $30.70 |
| Nightly batch job | 10,000 | 10K in / 2K out | $228 |
Caching the 45K-token prefix saves about 70% on the RAG workload versus sending it uncached every call ($102 → $30.70). Batch mode halves the nightly job.
Where GPT-5.2 sits in the market
Out of 28 models in this dataset, GPT-5.2 ranks #14 cheapest by input rate, #21 by output rate, and #21 on a blended 1M-input-plus-250K-output workload.
| Model | Provider | Input | Output | Blended |
|---|---|---|---|---|
| GPT-5.2 | OpenAI | $1.75 | $14 | $5.25 |
| Gemini 3.1 Pro (Preview) | Google Gemini | $2 | $12 | $5 |
| GPT-5.4 | OpenAI | $2.50 | $15 | $6.25 |
| GPT-5.6 Terra | OpenAI | $2 | $12 | $5 |
Blended cost = 1M input tokens + 250K output tokens at list price.
