MiniCPM-o 4.5 MRv2 profiles¶

Turn mode uses the stage-level MRv2 contracts from #8184. Thinker emits live latent metadata outside graph replay; Talker keeps codec history and EOS control on device. Code2Wav reuses mainline Whole-Euler Flow graphs and shared prompt state. The previous experimental block compilation, tiled attention, channels-last and merged-CFM implementations are removed.

minicpmo_4_5_turn_mrv2_h200.yaml selects Talker capacity 16 and 4 GiB KV; the generic MRv2 profile selects capacity 8 and 2 GiB KV. These configurations require new end-to-end performance measurements after the mainline integration. Previously reported numbers do not describe this revised codec backend.

The generic MRv2 profile and the opt-in native V1 duplex H200 profile enable TF32 matmuls within Code2Wav forward/capture only; the previous process policy is restored afterwards. cuDNN's TF32 policy is independent. TF32 changes rounding. Duplex keeps the mainline V1 session path. Turn results do not establish duplex performance or interruption correctness.

The shared asynchronous output snapshot and batched Talker preprocessing also apply to V1 when async chunking/scheduling is enabled. Default V1 behavior must therefore be included in end-to-end regression validation.
