+- [10/15/2026] [**Muse-Spark-Open-816B-A42B**](examples/models/muse_spark_open/README.md) is now supported! Megatron Bridge adds checkpoint conversion, inference, and GB200 training recipes for the 816B-total / 42B-active vision-and-audio-language MoE model: pretraining, full SFT, long-context SFT at 32K and 64K with context parallelism, LoRA, and image-text SFT and LoRA, with HybridEP MoE dispatch. See the [examples README](examples/models/muse_spark_open/README.md) and the [verification card](examples/model_verification_cards/muse-spark-open-816b-a42b/card.yaml) for details.
