Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Solar Mini | Ministral 3 8B |
|---|---|---|
| Input ($/M tokens) | $0.15 | $0.15 |
| Output ($/M tokens) | $0.15 | $0.15 |
Verdict. Solar Mini and Ministral 3 8B split the benchmark comparison evenly at 1–1. The tiebreaker here is price, speed, and what you actually run them on.
Pricing. Both models sit in the budget bracket for output-token pricing. At 1.0× the per-million-token cost, Ministral 3 8B is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Ministral 3 8B makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Solar Mini is strongest on Intelligence Index (6.4). Ministral 3 8B leads on Coding Index (9.7), Intelligence Index (5.5).
Speed. Speed data is incomplete for this pair; benchmark and price should decide.
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 Mini costs $6.75 ($81/year); Ministral 3 8B costs $6.75 ($81/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Solar Mini ≈ $1.05/run, Ministral 3 8B ≈ $1.05/run. At agent/realtime scale (200M input / 100M output per million requests): Solar Mini ≈ $45/run, Ministral 3 8B ≈ $45/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.
