# DNA-DiskChat-2B-PEER-v25-Code

Recurrent PEER code model. This card is generated from measured JSON. Missing values remain **not measured**.

## Model Details

| Field | Value |
|---|---:|
| Logical parameters | 1999254018 |
| Active parameters/token | 40189952 |
| Checkpoint bytes | 195637409 |
| Effective bits/parameter | 0.783 |
| Compression validation CE delta | 4.952 |
| Compression quality gate (`<= +0.01`) | False |
| License | apache-2.0 |

## Code Benchmarks

EvalPlus results use greedy pass@1 generation. Base and Plus tests are reported separately.

| Benchmark | Base pass@1 | Plus pass@1 | Tasks |
|---|---:|---:|---:|
| HumanEval | 0.00% | 0.00% | 164 |
| MBPP | 0.00% | 0.00% | 378 |

## Training Throughput

| Metric | Value |
|---|---:|
| Mean tokens/s | 55,503.942 |
| Median tokens/s | 55,655.991 |
| Measured windows | 24611 |

## NVMe `O_DIRECT` Benchmark

This transport benchmark measures random compressed-page lookups, not model tokens. `O_DIRECT` bypasses Linux page cache but not NVMe controller caches.

| Metric | Value |
|---|---:|
| Page lookups/s | 9,276.357 |
| p50 latency | 58.041 us |
| p95 latency | 206.685 us |
| Requested bytes/lookup | 4096 |
| Useful bytes/lookup | 3,000.000 |
| Direct NVMe qualified | False |
| Filesystem | overlayfs |

## Intended Use

Research on compact recurrent code generation and sparse expert routing. Generated code is untrusted; review it and execute only in a sandbox.

## Limitations

- Benchmark scores do not establish security, correctness, or production readiness.
- Missing metrics were not measured and are not estimated from plans or earlier model versions.
- EvalPlus execution runs untrusted model-generated Python and requires isolation.
- Page-lookup/s is not inference tok/s. Token speed requires integrated router, decoder, and expert compute.
