Each GLM 5.3 cost is the average of what OpenRouter charged us for its replies to one job's prompts; tokens out include any reasoning. Passed: how many of those GLM 5.3 replies passed their check. In llmwise a GLM 5.3 message isn't billed by the token.

Across all 50 GLM 5.3 replies: $0.00073 on average, $0.00046 at the median, $0.00013 for the cheapest and $0.0062 for the dearest. The GLM 5.3 replies averaged 518 tokens in and 152 out, against the typical message's 4,000 in and 700 out: each test prompt starts a new chat, while a reply deep in a long chat rereads all of it.

Every prompt, and how each reply is scored.
