Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Kimi K2.5 (Reasoning) | Qwen3 235B A22B (Non-reasoning) |
|---|---|---|
| Input ($/M tokens) | $0.6 | $0.7 |
| Output ($/M tokens) | $2.75 | $2.8 |
Verdict. Kimi K2.5 (Reasoning) wins the overall benchmark matchup 2–0 across 2 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, Kimi K2.5 (Reasoning) is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Kimi K2.5 (Reasoning) makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Kimi K2.5 (Reasoning) is strongest on Coding Index (46.8), Intelligence Index (23.5). Qwen3 235B A22B (Non-reasoning) leads on Intelligence Index (8.3).
Speed. Speed data is incomplete for this pair; benchmark and price should decide.
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 K2.5 (Reasoning) costs $59.25 ($711/year); Qwen3 235B A22B (Non-reasoning) costs $63.00 ($756/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Kimi K2.5 (Reasoning) ≈ $8.50/run, Qwen3 235B A22B (Non-reasoning) ≈ $9.10/run. At agent/realtime scale (200M input / 100M output per million requests): Kimi K2.5 (Reasoning) ≈ $395/run, Qwen3 235B A22B (Non-reasoning) ≈ $420/run. Kimi K2.5 (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.
