Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Grok 4.20 0309 v2 (Non-reasoning) | Ling-2.6-1T |
|---|---|---|
| Input ($/M tokens) | $1.25 | $0.3 |
| Output ($/M tokens) | $2.5 | $2.5 |
Verdict. Ling-2.6-1T 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 1.0× the per-million-token cost, Ling-2.6-1T is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Ling-2.6-1T makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Grok 4.20 0309 v2 (Non-reasoning) is strongest on Intelligence Index (22.2). Ling-2.6-1T leads on Intelligence Index (26.6).
Speed. Speed data is incomplete for this pair; benchmark and price should decide.
Provider. SpaceXAI and InclusionAI sell to overlapping but distinct developer audiences: SpaceXAI tends to ship frontier reasoning models with premium positioning, while InclusionAI 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): Grok 4.20 0309 v2 (Non-reasoning) costs $75.00 ($900/year); Ling-2.6-1T costs $46.50 ($558/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Grok 4.20 0309 v2 (Non-reasoning) ≈ $11.25/run, Ling-2.6-1T ≈ $6.50/run. At agent/realtime scale (200M input / 100M output per million requests): Grok 4.20 0309 v2 (Non-reasoning) ≈ $500/run, Ling-2.6-1T ≈ $310/run. Ling-2.6-1T 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.
