Most teams overspend on every LLM request because they hardcode the most expensive model. Stockyard proves cheaper options work — then routes automatically.
Install Stockyard and send traffic through it. Lookout traces every request with cost, latency, and token count. The auto-insights engine analyzes your traces and tells you exactly where you're overspending.
Free — Lookout + InsightsLasso replays your real requests against cheaper models and scores quality side-by-side. Drover calibrates candidates automatically. You see the exact quality-cost tradeoff on your actual traffic — not benchmarks, your data.
Free — Drover (100/day) Individual $29.99 — LassoEnable Drover and every request gets routed to the cheapest model above your quality threshold. Three modes: cost (cheapest), speed (fastest), balanced. Cross-provider routing works out of the box — gpt-5.4 requests can land on gpt-5.4-nano if quality holds.
Pro $99.99 — Unlimited DroverInstall Stockyard. Send traffic. See your costs. Drover gives you 100 free optimized routes per day — no credit card needed.
Install StockyardThe biggest LLM cost savings come from three places: caching identical requests, routing to cheaper models when accuracy requirements allow it, and catching runaway loops before they exhaust your API budget. Stockyard's cache layer eliminates redundant calls — if the same prompt-model pair has been seen before, the cached response returns in under a millisecond with zero token cost. The model aliasing system lets you route development traffic to cheaper models while keeping production on your preferred provider. Cost tracking through Trough shows spend per model, per day, and per endpoint so you can identify which features are expensive and why.
The compound effect is significant. Teams running Stockyard typically see 30 to 60 percent reduction in LLM API costs, primarily from cache hits on repeated prompts. For applications with high prompt similarity — chatbots, document processing, code generation — the cache hit rate often exceeds 40 percent, which means 40 percent fewer tokens billed.
