Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | DeepSeek R1 Distill Llama 70B | Solar Pro 4 |
|---|---|---|
| Input ($/M tokens) | $0.7 | $0.3 |
| Output ($/M tokens) | $1.1 | $1.2 |
Verdict. Solar Pro 4 takes the aggregate benchmark matchup 2–0 across 2 categories. Real workloads usually care about a handful of specific tasks — see the per-benchmark table above.
Pricing. Both models sit in the budget bracket for output-token pricing. At 0.9× the per-million-token cost, DeepSeek R1 Distill Llama 70B is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). DeepSeek R1 Distill Llama 70B makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. DeepSeek R1 Distill Llama 70B is strongest on Intelligence Index (9.8). Solar Pro 4 leads on Coding Index (52.7), Intelligence Index (41.6).
Speed. On throughput, Solar Pro 4 generates tokens at 47 tok/s versus 25 tok/s — about 46% faster. On time-to-first-token, DeepSeek R1 Distill Llama 70B responds in 1020ms vs 2530ms, which matters most for chat-style UIs.
Provider. DeepSeek and Upstage sell to overlapping but distinct developer audiences: DeepSeek tends to ship frontier reasoning models with premium positioning, while Upstage 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 R1 Distill Llama 70B costs $37.50 ($450/year); Solar Pro 4 costs $27.00 ($324/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): DeepSeek R1 Distill Llama 70B ≈ $5.70/run, Solar Pro 4 ≈ $3.90/run. At agent/realtime scale (200M input / 100M output per million requests): DeepSeek R1 Distill Llama 70B ≈ $250/run, Solar Pro 4 ≈ $180/run. Solar Pro 4 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.
