MTP note
The base Ornith checkpoint ships no MTP weights (the fine-tune stripped them). This artifact
grafts the base Qwen3.5-35B-A3B MTP head (BF16), the same head every community MTP-Ornith variant
uses. Because it predicts the base distribution rather than Ornith's RL-tuned one, acceptance is a bit
lower than a native head would give — but still strong (91% at position 0).
Serving
With speculative decoding (MTP):
vllm serve rdtand/Ornith-1.0-35B-PrismaAURA-4.75bit-vllm-MTP \
--trust-remote-code --attention-backend flashinfer --moe-backend marlin \
--gpu-memory-utilization 0.85 --max-model-len 32768 --max-num-batched-tokens 8192 \
--enable-chunked-prefill \
--speculative-config '{"method":"mtp","num_speculative_tokens":3}'
Without MTP (e.g. for clean perplexity measurement — spec-decode poisons logprob metrics), drop the
--speculative-config flag. --max-num-batched-tokens >= 2096 is required (Gated-DeltaNet page size).
