Help AI systems find reusable context across private inference fleets, with faster long-context inference as the outcome.
Synapse is a router core plus adapters. It can run as a standalone gateway or integrate with private serving stacks and partner platforms.
Each request is mapped to a compatibility namespace covering model, tokenizer, chat template, KV layout, backend, tenant scope, and provider version. Unsafe or unknown namespaces fail closed.
Synapse tracks semantic donor evidence, endpoint identity, backend capability, accelerator metadata, freshness, provider generation, and tenant policy scope across the fleet.
The route decision balances donor quality, backend capability, endpoint health, load, region, tenant rules, timeout budget, and exact/cold fallback.
Backend materialization, backend decline, stale donor, timeout, provider validation failure, and cold fallback are recorded separately. Dollar ROI is based on confirmed materialization, not semantic similarity alone.
Synapse can sit in front of self-hosted endpoints as an OpenAI-compatible gateway, or integrate with private serving stacks as a route advisor. The final API surface is deployment-specific.
Gateway mode gives teams a clean front door. Adapter mode lets private serving stacks stay in control while Synapse advises placement.
Embeddings, hashes, namespace metadata, freshness, and provider generation are used as placement evidence.
The serving stack decides whether reusable KV can be safely used for the request.
Unknown namespace, stale provider generation, timeout, or policy denial routes exact or cold.
Serving-stack and partner integrations call the same router core without owning proprietary scoring.
Serving-stack integrations treat Synapse as semantic KV evidence and route advice that composes with existing scheduling.
Synapse is not a response cache or a KV store. It is the semantic routing and feedback layer that helps serving stacks use compatible donor KV.

Synapse reports discovery, placement, backend confirmation, decline, and fallback separately so savings claims stay defensible.
Route outcome
Requests routed to an endpoint because it has stronger compatible donor evidence.
Backend event
Accepted donor KV, materialized token count, TTFT delta, and fallback state.
Confirmed only
Estimated prefill GPU time and dollar savings from reuse that actually lands.
