MiniCPM5-2B-DSpark
MiniCPM5-2B-DSpark
is a
DSpark
draft checkpoint trained for exact pairing with
MiniCPM5-2B
and its
tokenizer.
Model Specification
| Property | Value |
|---|---|
| Target model | MiniCPM5-2B |
| Draft layers | 5 |
| Draft parameters | 323,776,001 |
| Draft tokens per forward pass | 7 |
| Target hidden-state layers |
[1, 10, 20, 30, 39]
|
| Checkpoint precision | BF16 |
Training Recipe
Training responses were generated by MiniCPM5-2B from a mixture of general-domain, mathematics, and code prompts.
| Setting | Value |
|---|---|
| Training sequences | 1,959,525 |
| Training tokens | 7,054,154,509 |
| Epochs | 6 |
| Maximum sequence length | 12,288 |
| Optimizer | AdamW |
| Objective | CE + L1 + confidence loss |
Evaluation
Acceptance length is defined as the total number of completion tokens divided
by the total number of speculative verification steps. Evaluation uses natural
EOS termination and
max_new_tokens=4096
.
