SPARTAK FUSION · SMART ORDER ROUTER
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. Fuse your own models alongside open-source and frontier ones, fine-tune ultra-specific models for individual workflows, and combine traditional ML with LLMs — all inside your perimeter, every 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 ]
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
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
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
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.
FUSE YOUR OWN MODELS
Fusion isn't only routing across third-party APIs. Bring your proprietary or in-house models and Spartak fuses them with open-source and frontier models inside your perimeter — so the output is genuinely yours, not rented from a single vendor.
FINE-TUNING & TASK-SPECIFIC MODELS
Spartak fine-tunes models and builds ultra-specific, task-specific models for individual workflows — trained on your own data, inside the seal. Instead of forcing one general model to do everything, narrow models do one job extremely well.
TRADITIONAL ML + MLOPS
Beyond LLMs, Spartak brings traditional machine-learning expertise — forecasting, classification, anomaly detection, optimisation — layered on a full sovereign MLOps capability. Many real workflows are best solved by combining traditional ML with LLMs; Spartak does both, not just the generative layer.
[ SPARTAK API ]
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
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.
HOSTED · MANAGED
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.
