The model and the runtime version changed together. The difference is not attributed to 3.8.53 alone.

How we measured

Client: Pablo Tadini Soto (Pasblinn). Design: 3 regimes × 2 arms × 3 replicas. Stack: Simplicio Runtime 3.8.53, OpenCode 1.18.30 or later, main-round model qwen/qwen3.7-flash on Alibaba. Costs are US dollars from real OpenRouter charges, not estimates.

What the numbers show

Medium: $0.11890 without Simplicio → $0.00999 with the wrapper, −91.6% (t=−6.52, cheaper in 3 of 3). Large: $0.20947 → $0.04147, −80.2% (t=−4.67, 3 of 3). Small: $0.00462 → $0.00522, +13.2%, not significant (t=+0.77, 1 of 3). Peak context fell from 89 thousand tokens to 22 thousand in medium, and from 155 thousand to 32 thousand in large. The whole round cost $1.17 across 455 requests. A 15 Sep 2026 measurement with DeepSeek v4 Flash and Runtime 3.8.46 showed −72.2% medium and −62.5% large; this round is −91.6% and −80.2%. The model and the runtime version changed together — the gap is not attributed to 3.8.53 alone.

Limits of the result

This is one client round, not a guarantee. Do not read the medium-regime −91.6% as a typical or minimum saving. The strong drop appeared only in the medium and large regimes. In the small regime the wrapper cost more, and the difference was not significant. Savings depend on task size, model, and workflow.
