How to choose
These points use each model's cheapest-group prices and catalog data. Before going live, run real requests with a key in your target group and check quality, speed and billing.
- Input-heavy work (questions over long documents, classification, extraction): gpt-5.5 has the lower input price (¥10 vs ¥12.8 per 1M tokens).
- Output-heavy work (long-form writing, long answers): glm-5.3 has the lower output price (¥44.8 vs ¥80 per 1M tokens).
- When you resend the same long prefix (a fixed system prompt, the same long document), cached input is billed at the cache-read price: gpt-5.5 ¥1, glm-5.3 ¥3.2 (per 1M tokens).
- Both support Chat Completions, so requests look the same and switching means changing the model parameter (the key's groups must offer both models).
- If production needs a known request source, use official or cloud groups. gpt-5.5: Azure, Azure Plus, OpenAI Direct, OpenAI Direct Plus and Official · Enterprise; glm-5.3: none on this site.
