SparkRing RC4 composes the September 23 eugr ARM64 foundation with audited LIL vLLM/B12X changes, SparkRing's transport/prefill integrations, and persistent-cache support.

docker pull ghcr.io/fujitsupolycom/sparkring:shared-2026.09.4-rc.4

Immutable image: ghcr.io/fujitsupolycom/sparkring@sha256:3d3411b66dd2a4f78ea062ec0a923308f302df14f0e0f9a6ae8961946ae603c8.

  • Qwen TP2 and TP4 passed bounded text, all-rank status and physical cache restoration after restart. TP4 retains HC token-row ownership and the tested collective routing.
  • Final TP4 cold C1 prefill medians: 4,515 tok/s at 8K; 4,653 at 32K, three runs each with zero cached prompt tokens. This does not establish decode or concurrent-load throughput.
  • New GET /v1/sparkring/status reports configured/effective settings and passive worker metadata through the inference API.
  • Source archives, reconstructable patches, the 409-entry PR disposition inventory, runtime-status wheel/source, build context and validation records are attached. The image's 5,792 owned runtime files verified after an anonymous Docker pull.

Use the deployment guide, TP2 profile, or TP4 profile.

This is an opt-in research prerelease. Stable defaults remain unchanged. Profiles retain MTP3/16 sequences/capture ceiling 64; MTP5, MXFP8 LM-head activation and w13 scaling remain separate experiments. Full-context pressure, sustained load, arbitrary media and full MiMo serving are not qualified. See the qualification record for exact scope and source identities.
