+# FlashNext-MoE-9B-A1B
+
+Randomly initialized, language-only `Qwen4ExpForCausalLM` checkpoint.
+
+- Parameters: 9,000,082,560 (9.000082560B)
+- Approximate active backbone parameters per token: 0.995B
+- 32 layers: 24 Gated DeltaNet and 8 Qwen Sparse Attention
+- 64 routed experts, top-2, plus one shared expert per layer
+- No vision tower and no MTP head
+- BF16 weights in five safetensors shards
+- Qwen3.8-Flash-Next tokenizer and chat template
+
+These weights are random and must be pretrained or distilled before useful
+inference.
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+path = "/path/to/flashnext-moe-9b/model"
+tokenizer = AutoTokenizer.from_pretrained(path)
+model = AutoModelForCausalLM.from_pretrained(path, dtype="bfloat16")
