Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Agnes 2.5 Pro Alpha | GLM-4.6V (Reasoning) |
|---|---|---|
| Input ($/M tokens) | $0.45 | $0.3 |
| Output ($/M tokens) | $0.9 | $0.9 |
Verdict. GLM-4.6V (Reasoning) takes the aggregate benchmark matchup 6–5 across 11 categories. Real workloads usually care about a handful of specific tasks — see the per-benchmark table above.
Pricing. Both models sit in the budget bracket for output-token pricing. At 1.0× the per-million-token cost, GLM-4.6V (Reasoning) is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). GLM-4.6V (Reasoning) makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Agnes 2.5 Pro Alpha is strongest on GPQA Diamond (88%), Coding Index (58.8), SciCode (42%). GLM-4.6V (Reasoning) leads on AIME 2025 (85%), Math Index (85.3), MMLU-Pro (80%).
Speed. On throughput, Agnes 2.5 Pro Alpha generates tokens at 134 tok/s versus 0 tok/s — about 100% faster. On time-to-first-token, GLM-4.6V (Reasoning) responds in 0ms vs 1929ms, which matters most for chat-style UIs.
Provider. Sapiens AI and Z AI sell to overlapping but distinct developer audiences: Sapiens AI tends to ship frontier reasoning models with premium positioning, while Z AI often prices more aggressively. Your existing vendor relationships, billing, and SLA preferences may matter as much as the raw numbers above.
Workload cost. Workload scenarios (per million requests at 30M input + 15M output tokens): Agnes 2.5 Pro Alpha costs $27.00 ($324/year); GLM-4.6V (Reasoning) costs $22.50 ($270/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Agnes 2.5 Pro Alpha ≈ $4.05/run, GLM-4.6V (Reasoning) ≈ $3.30/run. At agent/realtime scale (200M input / 100M output per million requests): Agnes 2.5 Pro Alpha ≈ $180/run, GLM-4.6V (Reasoning) ≈ $150/run. GLM-4.6V (Reasoning) becomes more attractive at higher volume — the absolute per-token pricing difference compounds when you ship at scale.
Recommendation. Both models have legitimate use cases — the right answer depends on whether you are optimizing for benchmark ceiling, latency, or unit cost. Start with the cheaper / faster model, evaluate against your specific task, and only switch if the upgrade shows a meaningful lift.
