GLM-5 - AI Model API and Pricing

Bilingual work at a low rate

GLM-5 comes from Z.ai, and its listed strengths are working well bilingually and a low rate. That points it at jobs like localizing a product page. Another is drafting a newsletter in two languages from one brief. It can also produce a working translation that a native speaker then polishes.

A working translation is a draft for review, not a certified text. Have someone fluent check names, units and idioms before anything goes live.

Presets and prompts that fit

Open the AI Article Generator. Product description and Newsletter are the natural presets for market launches; Ad copy suits short localized variants. The tool takes no uploads, so paste the source copy into the prompt.

Try: "Translate the product description below into Simplified Chinese for an online shop audience. Keep the size table in metric, keep the brand name in English, and keep sentences short." Or: "Write the same 200-word launch note twice, first in English, then in Japanese. Adjust the call to action for each market."

Costs from real jobs

An 800-word blog post rounds up to 1k words and costs 6 credits, about $0.06 at the best pack. Double that length to 2,000 words and the run takes 12 credits, near $0.13. It is 4th from the cheapest of the 10 text models billed this way.

Fewer shared prompts to copy

The listed limit is a smaller prompt community. You will find fewer ready-made prompt recipes for GLM-5 than for the most popular models. Expect to write your own instructions and save the ones that work.

Gemini 3 Flash is a credit cheaper at 5 and is tuned for short, high-volume descriptions. DeepSeek V4, at 2 credits, is the low-cost choice for long, argued articles. Claude Haiku 4.5 costs 8 credits and writes natural-sounding captions and headlines in English.
