Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Celeris-1 | Qwen3.8 Max |
|---|---|---|
| Input ($/M tokens) | $2 | $2 |
| Output ($/M tokens) | $6 | $6 |
Verdict. Qwen3.8 Max takes the aggregate benchmark matchup 5–0 across 5 categories. Real workloads usually care about a handful of specific tasks — see the per-benchmark table above.
Pricing. Both models sit in the mid-tier bracket for output-token pricing. At 1.0× the per-million-token cost, Qwen3.8 Max is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Qwen3.8 Max makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Celeris-1 is strongest on GPQA Diamond (63%), SciCode (21%), Coding Index (14.4). Qwen3.8 Max leads on GPQA Diamond (92%), Coding Index (68.9), Intelligence Index (53.4).
Speed. On throughput, Celeris-1 generates tokens at 2195 tok/s versus 49 tok/s — about 98% faster. On time-to-first-token, Celeris-1 responds in 482ms vs 1569ms, which matters most for chat-style UIs.
Provider. Celeris and Alibaba sell to overlapping but distinct developer audiences: Celeris 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): Celeris-1 costs $150.00 ($1800/year); Qwen3.8 Max costs $150.00 ($1800/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Celeris-1 ≈ $22.00/run, Qwen3.8 Max ≈ $22.00/run. At agent/realtime scale (200M input / 100M output per million requests): Celeris-1 ≈ $1000/run, Qwen3.8 Max ≈ $1000/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.
