Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | DeepSeek V4.1 Flash (Reasoning, Max Effort) | MiniMax-M2.5 |
|---|---|---|
| Input ($/M tokens) | $0.3 | $0.3 |
| Output ($/M tokens) | $1.2 | $1.2 |
Verdict. DeepSeek V4.1 Flash (Reasoning, Max Effort) 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, MiniMax-M2.5 is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). MiniMax-M2.5 makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. DeepSeek V4.1 Flash (Reasoning, Max Effort) is strongest on Intelligence Index (39.5). MiniMax-M2.5 leads on Intelligence Index (22.8).
Speed. On throughput, DeepSeek V4.1 Flash (Reasoning, Max Effort) generates tokens at 223 tok/s versus 93 tok/s — about 58% faster. On time-to-first-token, DeepSeek V4.1 Flash (Reasoning, Max Effort) responds in 1190ms vs 1680ms, which matters most for chat-style UIs.
Provider. DeepSeek and MiniMax sell to overlapping but distinct developer audiences: DeepSeek tends to ship frontier reasoning models with premium positioning, while MiniMax 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 V4.1 Flash (Reasoning, Max Effort) costs $27.00 ($324/year); MiniMax-M2.5 costs $27.00 ($324/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): DeepSeek V4.1 Flash (Reasoning, Max Effort) ≈ $3.90/run, MiniMax-M2.5 ≈ $3.90/run. At agent/realtime scale (200M input / 100M output per million requests): DeepSeek V4.1 Flash (Reasoning, Max Effort) ≈ $180/run, MiniMax-M2.5 ≈ $180/run.
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.
