SPARTAK FUSION · SMART ORDER ROUTER
Score. Route. Fuse. Own the Output.
The Smart Order Router is Spartak Fusion's engineered selection pipeline — score every candidate model against the task and business case, route to the optimal model, and fuse only when multiple outputs add value. Representative workloads show measurable cost efficiency versus single-model baselines, with every inference staying inside your perimeter and every routing decision auditable.
Representative Smart Order Router trace: contract clause extraction task scored across three candidate models, routed to specialist-legal-ft, fusion applied when multiple outputs add value, assembled result with 61% cost delta versus single-model baseline, perimeter secure.
[ SMART ORDER ROUTER ]
Score every candidate. Route to optimal. Fuse only when it adds value.
Representative pipeline: Spartak scores each candidate model on cost, latency, accuracy, and compliance → routes to the highest composite score → fuses outputs only when multiple models add value. Engineered selection, not blind dispatch.

COST DELTA
-61% vs frontier-only
Smart Order Router pipeline for contract clause extraction: three candidate models scored on cost, latency, accuracy, and compliance; specialist-legal-ft routed as optimal; fusion applied when multiple outputs add value; result assembled with 61% cost delta versus frontier-only routing.
SMART ORDER ROUTING
Score every candidate — route to optimal, not default.
The Smart Order Router evaluates every candidate model on cost, latency, accuracy, and compliance before dispatch. Representative routing: contract-review tasks score a specialist legal model highest and route there — general reasoning stays on the optimal frontier route. Engineered selection, not blind prompt-and-hope.
INTELLIGENT FUSION
Fuse only when multiple models add value.
Fusion is gated by scoring — Spartak combines outputs from parallel model runs only when the composite score proves multiple models add value. Assembled deliverables are schema-enforced, policy-checked, and traceable to each source model. You own the output; no single vendor owns the pipeline.
TOKEN EFFICIENCY AS VALUE
Engineered efficiency — frontier quality at optimal-model cost.
The Smart Order Router routes each task to the cheapest model that meets your quality threshold. Representative efficiency: ~61% lower token cost versus always-on frontier routing — value delivered by orchestration intelligence, not a discount on someone else's API.
[ SPARTAK API ]
OpenAI-compatible endpoint — two delivery modes, one Fusion engine.
The Spartak API is a secondary surface under Fusion. Choose the mode that matches your sensitivity profile — the Smart Order Router and Fusion engine are identical; only the deployment boundary changes.
IN-PERIMETER · FLAGSHIP
Your apps call Spartak — not external providers.
Deploy an OpenAI-compatible endpoint inside your perimeter. Internal applications stop calling Azure, Bedrock, or public APIs — routing, fusion, and governance stay air-gapped with zero external dependency.
- → Full sovereignty — data never leaves the seal
- → Smart Order Router cost-efficiency on every internal call
- → Same Govern policy gates as the core engine
HOSTED · MANAGED
Managed endpoint for lower-sensitivity workloads.
A Spartak-managed API for development, prototyping, and non-regulated workloads. Smart Order Router efficiency and Fusion routing apply — suited for teams that do not require an air-gapped deployment.
- → OpenAI-compatible — drop-in for existing SDKs
- → Smart Order Router — engineered routing efficiency
- → Managed infrastructure — no bare-metal ops
