Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Solar Pro 3 | Mistral Small (Feb '24) |
|---|---|---|
| Input ($/M tokens) | $0.15 | $0.15 |
| Output ($/M tokens) | $0.6 | $0.6 |
Verdict. Solar Pro 3 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, Mistral Small (Feb '24) is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Mistral Small (Feb '24) makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Solar Pro 3 is strongest on Coding Index (16.2), Intelligence Index (14.5). Mistral Small (Feb '24) leads on Intelligence Index (3.2).
Speed. Throughput is comparable — 152 tok/s vs 150 tok/s — so generation speed shouldn't drive your choice here. Look at the per-benchmark wins instead.
Provider. Upstage and Mistral sell to overlapping but distinct developer audiences: Upstage tends to ship frontier reasoning models with premium positioning, while Mistral 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): Solar Pro 3 costs $13.50 ($162/year); Mistral Small (Feb '24) costs $13.50 ($162/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Solar Pro 3 ≈ $1.95/run, Mistral Small (Feb '24) ≈ $1.95/run. At agent/realtime scale (200M input / 100M output per million requests): Solar Pro 3 ≈ $90/run, Mistral Small (Feb '24) ≈ $90/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.
