Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Qwen3 Coder Next | Solar Pro 4 |
|---|---|---|
| Input ($/M tokens) | $0.35 | $0.3 |
| Output ($/M tokens) | $1.2 | $1.2 |
Verdict. Solar Pro 4 takes the aggregate benchmark matchup 2–0 across 2 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, Solar Pro 4 is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Solar Pro 4 makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Qwen3 Coder Next is strongest on Coding Index (36.2), Intelligence Index (21.3). Solar Pro 4 leads on Coding Index (52.7), Intelligence Index (41.6).
Speed. On throughput, Qwen3 Coder Next generates tokens at 139 tok/s versus 47 tok/s — about 66% faster. On time-to-first-token, Qwen3 Coder Next responds in 1030ms vs 2530ms, which matters most for chat-style UIs.
Provider. Alibaba and Upstage sell to overlapping but distinct developer audiences: Alibaba tends to ship frontier reasoning models with premium positioning, while Upstage 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): Qwen3 Coder Next costs $28.50 ($342/year); Solar Pro 4 costs $27.00 ($324/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Qwen3 Coder Next ≈ $4.15/run, Solar Pro 4 ≈ $3.90/run. At agent/realtime scale (200M input / 100M output per million requests): Qwen3 Coder Next ≈ $190/run, Solar Pro 4 ≈ $180/run. Solar Pro 4 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.
