We describe gaps under 1 point as small, 1–under 5 as noticeable, and 5 or more as large. These are reading aids, not proof that a difference would hold up in repeated tests. Equal scores can still hide different mistakes.

YOUR WORKLOAD

Reasoning-token cost calculator

Estimate the extra bill from thinking tokens. The starting token counts are editable examples, not measurements of GLM 5.3. Rates start from the current model snapshot.

A · Low$10.6estimated monthly cost
B · Max$29.8estimated monthly cost

Mode B costs $19.2 more per month with these assumptions.

This estimate uses the token counts and prices you enter. Excludes retries, tools, caching, long-context premiums, hosting and taxes. Includes thinking in output billing; do not also include it in “visible output.” Check endpoint limits separately. Changing mode does not automatically predict tokens or quality.

Reasoning effort, explained

Which GLM 5.3 thinking level is most efficient?

Max is the lowest-cost option within 1 point of the best analytics score in Hex DataBench v1.1. The tested score range is 7.7 points. This allows a score up to 1 point below the best result in the first listed study. Change the study, task and allowed score gap above to explore another comparison. It is a shortlist for testing your own workload.

Which GLM 5.3 effort settings are compared?

Low, High, Max appear in the collected studies. Each chart only includes modes tested together in that study. These published labels do not establish that every endpoint or application exposes every setting.

Does more effort improve GLM 5.3?

In the first listed Hex DataBench v1.1 sweep, the tested score range is 7.7 points and no adjacent effort increase lowers the score. This does not guarantee a gain on every task or with a different testing setup.

How much more does high effort cost for GLM 5.3?

Use the A/B selector and measured-cost calculator when the source reports dollar costs. For your own agent, enter average input, visible output and thinking tokens in the token calculator. Higher effort is adaptive, so the label itself cannot tell you the bill. Missing costs stay missing.
