Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Apriel-v1.6-15B-Thinker | GLM-4.5V (Non-reasoning) |
|---|---|---|
| Input ($/M tokens) | $0 | $0.6 |
| Output ($/M tokens) | $0 | $1.8 |
Verdict. Apriel-v1.6-15B-Thinker wins the overall benchmark matchup 1–0 across 1 overlapping categories, but raw benchmark score is only one input to the decision.
Pricing. Pricing varies significantly between these models — check the table above for the exact per-token rates. Many production workloads actually surface input-token cost (retrieval-augmented prompts, code-context windows), so factor both directions.
Strengths. Apriel-v1.6-15B-Thinker is strongest on Intelligence Index (13.4). GLM-4.5V (Non-reasoning) leads on Intelligence Index (6.7).
Speed. Speed data is incomplete for this pair; benchmark and price should decide.
Provider. ServiceNow and Z AI sell to overlapping but distinct developer audiences: ServiceNow 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): Apriel-v1.6-15B-Thinker costs $0.00 ($0/year); GLM-4.5V (Non-reasoning) costs $45.00 ($540/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Apriel-v1.6-15B-Thinker ≈ $0.00/run, GLM-4.5V (Non-reasoning) ≈ $6.60/run. At agent/realtime scale (200M input / 100M output per million requests): Apriel-v1.6-15B-Thinker ≈ $0/run, GLM-4.5V (Non-reasoning) ≈ $300/run. Apriel-v1.6-15B-Thinker 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.
Data from Artificial Analysis API — 12 benchmarks
Apriel-v1.6-15B-Thinker is cheaper overall. Its blended price (3:1 input/output ratio) is $0.00/M tokens vs $0.90/M for GLM-4.5V (Non-reasoning).
