Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Hy3 | gpt-oss-120b (low) |
|---|---|---|
| Input ($/M tokens) | $0.14 | $0.15 |
| Output ($/M tokens) | $0.55 | $0.59 |
Verdict. Hy3 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 0.9× the per-million-token cost, Hy3 is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Hy3 makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Hy3 is strongest on Coding Index (58.8), Intelligence Index (42.2). gpt-oss-120b (low) leads on Coding Index (21.2), Intelligence Index (14.9).
Speed. On throughput, gpt-oss-120b (low) generates tokens at 154 tok/s versus 94 tok/s — about 39% faster. On time-to-first-token, gpt-oss-120b (low) responds in 870ms vs 2750ms, which matters most for chat-style UIs.
Provider. Tencent and OpenAI sell to overlapping but distinct developer audiences: Tencent tends to ship frontier reasoning models with premium positioning, while OpenAI 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): Hy3 costs $12.45 ($149/year); gpt-oss-120b (low) costs $13.35 ($160/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Hy3 ≈ $1.80/run, gpt-oss-120b (low) ≈ $1.93/run. At agent/realtime scale (200M input / 100M output per million requests): Hy3 ≈ $83/run, gpt-oss-120b (low) ≈ $89/run. Hy3 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.
