Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | DeepSeek V4 Flash 0731 (Reasoning, Max Effort) | Muse Glimmer (high) |
|---|---|---|
| Input ($/M tokens) | $0.44 | $0.32 |
| Output ($/M tokens) | $1.32 | $1.35 |
Verdict. DeepSeek V4 Flash 0731 (Reasoning, Max Effort) 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, DeepSeek V4 Flash 0731 (Reasoning, Max Effort) is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). DeepSeek V4 Flash 0731 (Reasoning, Max Effort) makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. DeepSeek V4 Flash 0731 (Reasoning, Max Effort) is strongest on Coding Index (69.1), Intelligence Index (51.8). Muse Glimmer (high) leads on Coding Index (49.0), Intelligence Index (35.1).
Speed. On throughput, DeepSeek V4 Flash 0731 (Reasoning, Max Effort) generates tokens at 140 tok/s versus 109 tok/s — about 22% faster. On time-to-first-token, Muse Glimmer (high) responds in 790ms vs 1190ms, which matters most for chat-style UIs.
Provider. DeepSeek and Meta sell to overlapping but distinct developer audiences: DeepSeek 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): DeepSeek V4 Flash 0731 (Reasoning, Max Effort) costs $33.00 ($396/year); Muse Glimmer (high) costs $29.85 ($358/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): DeepSeek V4 Flash 0731 (Reasoning, Max Effort) ≈ $4.84/run, Muse Glimmer (high) ≈ $4.30/run. At agent/realtime scale (200M input / 100M output per million requests): DeepSeek V4 Flash 0731 (Reasoning, Max Effort) ≈ $220/run, Muse Glimmer (high) ≈ $199/run. Muse Glimmer (high) 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.
Data from Artificial Analysis API — 12 benchmarks
Muse Glimmer (high) is cheaper overall. Its blended price (3:1 input/output ratio) is $0.58/M tokens vs $0.66/M for DeepSeek V4 Flash 0731 (Reasoning, Max Effort).
