o4 Mini vs GLM 4.6V: common questions

Is o4 Mini better than GLM 4.6V?

o4 Mini ranks higher on the ModelCap Index as of 19 September 2026: #105 against #108. That is a capability ranking built from public benchmark evidence with published uncertainty; whether it is "better" for you also depends on price, context and where you can run it. Their published uncertainty intervals overlap, so the rank difference alone does not establish a reliable capability advantage for your workload.

Is o4 Mini cheaper than GLM 4.6V?

GLM 4.6V is cheaper on output tokens: $0.90/1M against $4.40/1M. Input tokens are $1.10/1M for o4 Mini and $0.30/1M for GLM 4.6V. Prices are the lowest listed API offer ModelCap observed, in USD per million tokens. For 1,000 requests with 2,000 input and 500 output tokens each (2M input + 0.5M output), the listed-rate estimate is $4.40 for o4 Mini versus $1.05 for GLM 4.6V. GLM 4.6V costs 76.1% less in this scenario. This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the selected endpoint before budgeting.

Which has the bigger context window, o4 Mini or GLM 4.6V?

o4 Mini has the larger context window: 200K tokens against 131K.

Which is better for coding, o4 Mini or GLM 4.6V?
