Fine-tuning framework comparison hides key assumptions about EP, SP and 2M context
StasBekman · x · 2026-07-26
The post reviews a comparison article on popular fine-tuning frameworks and says it is generally useful, but has a few important caveats.
Key corrections and notes:
- The article claims EP cannot be combined with CP, but the author says ALST/SP can work with EP and works well.
- Because SP overlaps with DP, you can reportedly run EP=8 + SP=8 on a single node and still reach a 2M sequence length even with a 30B MoE model.
- The article often quotes “max” numbers without clarifying whether they apply to one GPU or many GPUs, or what GPU size is assumed.
Overall, the author says the comparison is mostly useful, but readers should be careful about hidden assumptions around parallelism and hardware scale.
