Epic: serve HeartMuLa oss-3B song generation on the current fleet
The decisions settled on #378 (2026-10-17) resolve this epic's open ones. Async jobs exist from the start (#382), so HeartMuLa's latency needs no special surface. Its rate is a per-model DB row…
Pascal P6 (contingency): Stable Audio and/or EzAudio on Pascal if ACE-Step is a no-go
Licensing posture decided on #378 (2026-10-17), which reframes this issue's operator decision.
The question is not whether to adopt the Stability Community Licence for the platform; helexa…
HeartMuLa H1: licence diligence gate — MuQ-MuLan, Llama-3.2 lineage, provenance hashes
Licensing posture decided on #378 (2026-10-17), which reframes this issue's outcome.
helexa serves only what it is licensed to serve, and publishes its own terms, as permissive as it can make…
Music A9: /music route in the helexa.ai web UI
Epic: serve ACE-Step 1.5 text-to-music (songs with vocals) on the current fleet
Operator decisions (2026-10-17)
- Surface: async from the start. Jobs are the primary interface in v1 (submit → job id → poll/fetch, plus cancel), not a later add-on. Every music model…
Pascal P7 (optional): HeartMuLa as a multi-card render tier
Pascal P6 (contingency): Stable Audio and/or EzAudio on Pascal if ACE-Step is a no-go
Pascal P5: ACE-Step on Pascal — go/no-go gate
Pascal P4: rig bring-up — OS, driver pin, mesh, deploy (operator-gated)
Pascal P3: one model, many cards — per-card replicas and per-component placement in neuron + cortex
Pascal P2: sm_61 precision policy — q8 weights, fp32 compute, no fp16 math
Pascal P1: helexa-neuron-pascal build flavour (sm_61, CUDA 12.9)
runner-cuda-12.9: CUDA 12.x build image for Pascal (sm_61) targets
HeartMuLa H6: fleet rollout, validation and beta cut-over (definition of done)
HeartMuLa H5: memory discipline — LM/codec placement and the 19 GiB peak
HeartMuLa H4: candle port of HeartCodec (token-to-waveform decoder)
