Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Kimi K2 | Qwen3 Coder 30B A3B Instruct |
|---|---|---|
| Input ($/M tokens) | $0.57 | $0.45 |
| Output ($/M tokens) | $2.3 | $2.25 |
Verdict. Kimi K2 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, Qwen3 Coder 30B A3B Instruct is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Qwen3 Coder 30B A3B Instruct makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Kimi K2 is strongest on Intelligence Index (19.7). Qwen3 Coder 30B A3B Instruct leads on Intelligence Index (13.6).
Speed. On throughput, Qwen3 Coder 30B A3B Instruct generates tokens at 91 tok/s versus 41 tok/s — about 55% faster. On time-to-first-token, Kimi K2 responds in 1220ms vs 2540ms, which matters most for chat-style UIs.
Provider. Kimi and Alibaba sell to overlapping but distinct developer audiences: Kimi tends to ship frontier reasoning models with premium positioning, while Alibaba 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): Kimi K2 costs $51.60 ($619/year); Qwen3 Coder 30B A3B Instruct costs $47.25 ($567/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Kimi K2 ≈ $7.45/run, Qwen3 Coder 30B A3B Instruct ≈ $6.75/run. At agent/realtime scale (200M input / 100M output per million requests): Kimi K2 ≈ $344/run, Qwen3 Coder 30B A3B Instruct ≈ $315/run. Qwen3 Coder 30B A3B Instruct 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.
