Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | DeepSeek R1 (Jan '25) | Kimi K2.6 (Non-reasoning) |
|---|---|---|
| Input ($/M tokens) | $2 | $0.95 |
| Output ($/M tokens) | $4 | $4 |
Verdict. DeepSeek R1 (Jan '25) and Kimi K2.6 (Non-reasoning) split the benchmark comparison evenly at 1–1. The tiebreaker here is price, speed, and what you actually run them on.
Pricing. Both models sit in the mid-tier bracket for output-token pricing. At 1.0× the per-million-token cost, Kimi K2.6 (Non-reasoning) is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Kimi K2.6 (Non-reasoning) makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. DeepSeek R1 (Jan '25) is strongest on Coding Index (24.6), Intelligence Index (18.6). Kimi K2.6 (Non-reasoning) leads on Intelligence Index (35.4).
Speed. Speed data is incomplete for this pair; benchmark and price should decide.
Provider. DeepSeek and Kimi sell to overlapping but distinct developer audiences: DeepSeek tends to ship frontier reasoning models with premium positioning, while Kimi 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): DeepSeek R1 (Jan '25) costs $120.00 ($1440/year); Kimi K2.6 (Non-reasoning) costs $88.50 ($1062/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): DeepSeek R1 (Jan '25) ≈ $18.00/run, Kimi K2.6 (Non-reasoning) ≈ $12.75/run. At agent/realtime scale (200M input / 100M output per million requests): DeepSeek R1 (Jan '25) ≈ $800/run, Kimi K2.6 (Non-reasoning) ≈ $590/run. Kimi K2.6 (Non-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.
