Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Llama 3 Instruct 8B | Solar Mini |
|---|---|---|
| Input ($/M tokens) | $0.04 | $0.15 |
| Output ($/M tokens) | $0.14 | $0.15 |
Verdict. Solar Mini takes the aggregate benchmark matchup 1–0 across 1 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, Llama 3 Instruct 8B is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Llama 3 Instruct 8B makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Llama 3 Instruct 8B is strongest on Intelligence Index (1.0). Solar Mini leads on Intelligence Index (6.0).
Speed. Speed data is incomplete for this pair; benchmark and price should decide.
Provider. Meta and Upstage sell to overlapping but distinct developer audiences: Meta 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): Llama 3 Instruct 8B costs $3.30 ($40/year); Solar Mini costs $6.75 ($81/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Llama 3 Instruct 8B ≈ $0.48/run, Solar Mini ≈ $1.05/run. At agent/realtime scale (200M input / 100M output per million requests): Llama 3 Instruct 8B ≈ $22/run, Solar Mini ≈ $45/run. Llama 3 Instruct 8B 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.
