Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | GLM-4.7-Flash (Reasoning) | Llama Nemotron Super 49B v1.5 (Non-reasoning) |
|---|---|---|
| Input ($/M tokens) | $0.07 | $0.4 |
| Output ($/M tokens) | $0.4 | $0.4 |
Verdict. GLM-4.7-Flash (Reasoning) wins the overall benchmark matchup 1–0 across 1 overlapping categories, but raw benchmark score is only one input to the decision.
Pricing. Both models sit in the budget bracket for output-token pricing. At 1.0× the per-million-token cost, Llama Nemotron Super 49B v1.5 (Non-reasoning) is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Llama Nemotron Super 49B v1.5 (Non-reasoning) makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. GLM-4.7-Flash (Reasoning) is strongest on Intelligence Index (23.3). Llama Nemotron Super 49B v1.5 (Non-reasoning) leads on Intelligence Index (8.5).
Speed. On throughput, GLM-4.7-Flash (Reasoning) generates tokens at 83 tok/s versus 42 tok/s — about 49% faster. On time-to-first-token, GLM-4.7-Flash (Reasoning) responds in 1110ms vs 7040ms, which matters most for chat-style UIs.
Provider. Z AI and NVIDIA sell to overlapping but distinct developer audiences: Z AI tends to ship frontier reasoning models with premium positioning, while NVIDIA 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): GLM-4.7-Flash (Reasoning) costs $8.10 ($97/year); Llama Nemotron Super 49B v1.5 (Non-reasoning) costs $18.00 ($216/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): GLM-4.7-Flash (Reasoning) ≈ $1.15/run, Llama Nemotron Super 49B v1.5 (Non-reasoning) ≈ $2.80/run. At agent/realtime scale (200M input / 100M output per million requests): GLM-4.7-Flash (Reasoning) ≈ $54/run, Llama Nemotron Super 49B v1.5 (Non-reasoning) ≈ $120/run. GLM-4.7-Flash (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.
