What is Mancer
Mancer provides OpenAI-compatible inference for open language models. It is an API service without its own chat interface and uses prepaid credits rather than a recurring consumer subscription.
Credit packs
As of September 19, 2026, Basic costs US$4.99 for 1.25 million credits, Better costs US$19.99 for 5.5 million, Best costs US$49.99 for 15 million and Give Me the Tokens costs US$249.99 for 100 million credits. The corresponding published effective rates are approximately US$4, US$3.64, US$3.33 and US$2.50 per million credits, excluding tax.
Model usage and business billing
Each model consumes its displayed number of credits per input and output token, while MythoLite is currently free. Current examples include DeepSeek V4 Flash at 0.076 input and 0.200 output credits per token, GLM 4.7 at 0.280 and 1.000, Qwen 3.8 27B at 0.080 and 1.000, and GPT OSS 120B at 0.020 and 0.120. Mancer marks some endpoints as having problems; those remain listed but should be tested before production use.
Business accounts use custom arrangements with multiple API keys, request-logging controls and optional automatic weekly billing for consumed credits. Mancer offers free models for testing before a credit purchase.
