Which should you choose?

Choose GLM 5.3 for a 1M-token context window and more hosts to choose from on OpenRouter (37 against 1). Choose Inkling Small for the lower cost per correct answer ($0.00069 against $0.0014), faster streaming, a quicker first token and shorter outputs (about 273 tokens per question against 523). The widest subject gap is in engineering: GLM 5.3 answered 10 of 15 correctly, Inkling Small 6 of 15. With so few questions per subject, treat this as a lead to test on your own prompts, not a result.

Accuracy gap +0.0 points (z = 0.00). A winner is called only when z is at least 1.96, the usual 95% threshold. Speed, latency and price need a 10% margin.
