Benchmarks

Published Last reviewed Applies to SPM-Polaris V3.0.0

This page reports only currently valid evidence. Historical scores measured on a different recall shape, embedding backend, or incomplete runner are not presented as current production accuracy.

Verified production observations

Observation Result Scope
Long-history deterministic compression 66,265 original input tokens → 365 forwarded; 279 recalled; 99.45% less provider input One real, eligible hosted Provider Proxy request
Starter limiter burst 30 successful requests + 15 HTTP 429 responses from a 45-request burst One measured Starter 30 req/min window
New MCP memory readiness 8.23 seconds to ready One production remember/status round trip
MCP read integrity Stored and read text matched byte-for-byte Production remember → status → recall → read
Warm historical MCP recall 4.93 seconds One warm production observation; not an SLO

These are observations, not guarantees. Network distance, corpus size, provider latency, cold span indexing, protected protocol state, and request shape all affect results.

When token reduction appears

Deterministic compression needs both:

  1. input above the active budget (8,192 estimated tokens when no model-specific budget is available); and
  2. at least one complete old exchange that can be removed without touching protected state.

Therefore 0% on short, single-turn, or opaque histories is correct. Do not extrapolate the 99.45% example to every request.

Recall-quality status

The production embedding service now uses a privately operated Voyage 4 Nano-compatible embedding runtime and no hosted reranker. Historical LoCoMo/payload-recall figures measured with hosted Voyage Large/rerank or older harness shapes are not current evidence.

A 301-question run attempted across a high-latency tunnel degraded after dense-span timeouts and produced no valid result artifact. It is excluded. A current production-near re-anchor must separately report accuracy, abstention, latency, corpus state, and exact model/commit pins before a new recall-quality number is published.
