Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | GPT-5 mini (high) | Qwen3.5 35B A3B (Reasoning) |
|---|---|---|
| Input ($/M tokens) | $0.25 | $0.25 |
| Output ($/M tokens) | $2 | $2 |
Verdict. GPT-5 mini (high) and Qwen3.5 35B A3B (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 budget bracket for output-token pricing. At 1.0× the per-million-token cost, Qwen3.5 35B A3B (Reasoning) is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Qwen3.5 35B A3B (Reasoning) makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. GPT-5 mini (high) is strongest on Intelligence Index (25.8), Coding Index (15.6). Qwen3.5 35B A3B (Reasoning) leads on Intelligence Index (29.9).
Speed. On throughput, Qwen3.5 35B A3B (Reasoning) generates tokens at 151 tok/s versus 83 tok/s — about 45% faster. On time-to-first-token, Qwen3.5 35B A3B (Reasoning) responds in 2060ms vs 89370ms, which matters most for chat-style UIs.
Provider. OpenAI and Alibaba sell to overlapping but distinct developer audiences: OpenAI 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): GPT-5 mini (high) costs $37.50 ($450/year); Qwen3.5 35B A3B (Reasoning) costs $37.50 ($450/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): GPT-5 mini (high) ≈ $5.25/run, Qwen3.5 35B A3B (Reasoning) ≈ $5.25/run. At agent/realtime scale (200M input / 100M output per million requests): GPT-5 mini (high) ≈ $250/run, Qwen3.5 35B A3B (Reasoning) ≈ $250/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.
