Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Sarvam 105B (high) | gpt-oss-20b (high) |
|---|---|---|
| Input ($/M tokens) | $0.04 | $0.06 |
| Output ($/M tokens) | $0.17 | $0.19 |
Verdict. gpt-oss-20b (high) takes the aggregate benchmark matchup 2–0 across 2 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, Sarvam 105B (high) is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Sarvam 105B (high) makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Sarvam 105B (high) is strongest on Intelligence Index (11.9). gpt-oss-20b (high) leads on Coding Index (20.7), Intelligence Index (15.2).
Speed. Speed data is incomplete for this pair; benchmark and price should decide.
Provider. Sarvam and OpenAI sell to overlapping but distinct developer audiences: Sarvam tends to ship frontier reasoning models with premium positioning, while OpenAI 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): Sarvam 105B (high) costs $3.75 ($45/year); gpt-oss-20b (high) costs $4.65 ($56/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Sarvam 105B (high) ≈ $0.54/run, gpt-oss-20b (high) ≈ $0.68/run. At agent/realtime scale (200M input / 100M output per million requests): Sarvam 105B (high) ≈ $25/run, gpt-oss-20b (high) ≈ $31/run. Sarvam 105B (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
