Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Celeris-1 | Llama 4 Scout |
|---|---|---|
| Input ($/M tokens) | $0.2 | $0.19 |
| Output ($/M tokens) | $0.7 | $0.68 |
Verdict. Celeris-1 and Llama 4 Scout 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, Llama 4 Scout is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Llama 4 Scout makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Celeris-1 is strongest on Coding Index (14.4), Intelligence Index (6.3). Llama 4 Scout leads on Coding Index (8.2), Intelligence Index (6.5).
Speed. On throughput, Celeris-1 generates tokens at 1460 tok/s versus 121 tok/s — about 92% faster. On time-to-first-token, Celeris-1 responds in 600ms vs 850ms, which matters most for chat-style UIs.
Provider. Celeris and Meta sell to overlapping but distinct developer audiences: Celeris tends to ship frontier reasoning models with premium positioning, while Meta 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): Celeris-1 costs $16.50 ($198/year); Llama 4 Scout costs $15.90 ($191/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Celeris-1 ≈ $2.40/run, Llama 4 Scout ≈ $2.31/run. At agent/realtime scale (200M input / 100M output per million requests): Celeris-1 ≈ $110/run, Llama 4 Scout ≈ $106/run. Llama 4 Scout 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.
