Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Ministral 3 8B | Agnes 3.0 Flash |
|---|---|---|
| Input ($/M tokens) | $0.15 | $0.05 |
| Output ($/M tokens) | $0.15 | $0.15 |
Verdict. Ministral 3 8B and Agnes 3.0 Flash 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, Agnes 3.0 Flash is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Agnes 3.0 Flash makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Ministral 3 8B is strongest on Coding Index (9.7), Intelligence Index (5.5). Agnes 3.0 Flash leads on Intelligence Index (35.5).
Speed. On throughput, Agnes 3.0 Flash generates tokens at 237 tok/s versus 89 tok/s — about 62% faster. On time-to-first-token, Ministral 3 8B responds in 720ms vs 1840ms, which matters most for chat-style UIs.
Provider. Mistral and Sapiens AI sell to overlapping but distinct developer audiences: Mistral tends to ship frontier reasoning models with premium positioning, while Sapiens AI 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): Ministral 3 8B costs $6.75 ($81/year); Agnes 3.0 Flash costs $3.75 ($45/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Ministral 3 8B ≈ $1.05/run, Agnes 3.0 Flash ≈ $0.55/run. At agent/realtime scale (200M input / 100M output per million requests): Ministral 3 8B ≈ $45/run, Agnes 3.0 Flash ≈ $25/run. Agnes 3.0 Flash 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.
