Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Hy3 | Llama 3.1 Instruct 70B |
|---|---|---|
| Input ($/M tokens) | $0.14 | $0.56 |
| Output ($/M tokens) | $0.58 | $0.56 |
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 1.0× the per-million-token cost, Llama 3.1 Instruct 70B is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Llama 3.1 Instruct 70B 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 (25.8). Llama 3.1 Instruct 70B leads on Intelligence Index (6.6).
Speed. On throughput, Hy3 generates tokens at 91 tok/s versus 70 tok/s — about 23% faster. On time-to-first-token, Llama 3.1 Instruct 70B responds in 1760ms vs 2710ms, which matters most for chat-style UIs.
Provider. Tencent and Meta sell to overlapping but distinct developer audiences: Tencent tends to ship frontier reasoning models with premium positioning, while Meta 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 $12.90 ($155/year); Llama 3.1 Instruct 70B costs $25.20 ($302/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Hy3 ≈ $1.86/run, Llama 3.1 Instruct 70B ≈ $3.92/run. At agent/realtime scale (200M input / 100M output per million requests): Hy3 ≈ $86/run, Llama 3.1 Instruct 70B ≈ $168/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.
