FP8_DYNAMIC (FP8 E4M3 weights, per-token dynamic FP8 activations), produced with llm-compressor (quantization_scheme recorded in recipe.yaml).Linear layers of the language model are quantized; the vision tower, multi-modal projector, lm_head, and embeddings are kept in BF16. MTP (multi-token prediction) weights are preserved.quantization="compressed-tensors") or transformers.Measured on an NVIDIA A100 against the original BF16 checkpoint (greedy decoding, official translation prompt):
| Metric | BF16 | FP8 | Delta |
|---|---|---|---|
| Perplexity (fixed corpus) | 2.7722 | 2.7838 | +0.42% |
| zh→en generation identical | — | — | yes |
| en→zh generation identical | — | — | yes |

请将以下文本翻译为{target-language}，直接输出翻译结果，不要进行任何解释。 {source-text}Beyond plain translation, the models follow the instTrans constrained-translation format. The official client wraps requests into the canonical structure 【源文】<text> + numbered 1. 【硬性要求】<hard constraints> + 2. 【注意】<soft constraints> + suffix instructions:
碳纤维:carbon fiber, 抗裂缝:crack resistance), and format/structure preservation for JSON/CSV/code/placeholders.Full prompt reference: github.com/bilibili/Index-Translate (Instruction Following section, docs/prompts.md, inference/llm/cases/).
See the base model card for the full instTrans constrained-translation format and serving presets. GGUF builds for local inference are published in Index-Translate-9B-GGUF.
