Merge details
Method: element-wise linear interpolation of weights (computed in fp32, stored in bf16).
Architecture: LlamaForCausalLM, identical for both parents (hidden 2048, 24 layers, 32 heads, tied embeddings).
Vocabulary: 49280. The two parents share 49152 tokens (interpolated); the 128 extra EPE
"charter" tokens are carried over from the EPE parent unchanged. The EPE tokenizer is bundled.
