OpenMed-mLiteClinical-IrishPPSN-135M-v1-fp16

OpenMed-mLiteClinical-IrishPPSN-135M-v1-fp16 is a half-precision GPU-oriented release of temsa/OpenMed-mLiteClinical-IrishPPSN-135M-v1.

Use this release when you want the same PPSN masking behavior as the full model with lower memory use and faster inference on ROCm / CUDA GPUs, or on CPU when your serving path is low-batch and short-sequence.

What This Release Is

• A standard transformers checkpoint stored in fp16
• Derived from temsa/OpenMed-mLiteClinical-IrishPPSN-135M-v1
• Intended for PPSN masking with the bundled word_aligned decoder
• Works on CPU and GPU; it showed the largest speedup on GPU, and a CPU speedup on the current low-batch word_aligned path

Recommended Inference

Use the bundled entrypoint, which loads the checkpoint with dtype=auto so the stored fp16 weights are used directly. This is a good fit for low-batch CPU serving and for GPU inference:

python3 inference_word_aligned.py --ppsn-min-score 0.4 --text "My PPSN is 1234567TW and I need help with my housing grant." --json

To load directly from the Hub:

python3 inference_word_aligned.py --model temsa/OpenMed-mLiteClinical-IrishPPSN-135M-v1-fp16 --ppsn-min-score 0.4 --text "My PPSN is 1234567TW and I need help with my housing grant." --json

Benchmark Summary

Measured on the multilingual PPSN suite spanning gov data, citizen-to-government chat, and HSE medical text in English, Irish Gaelic, and additional European / Ukrainian / Russian / Chinese / Japanese examples.

CPU behavior depends on workload shape. The end-to-end word_aligned benchmark below is favorable to fp16, but the batched CPU runtime matrix in eval/runtime_matrix_cpu_fp32_vs_fp16_compact.md shows that fp16 loses to fp32 once batch size and sequence length grow.

For CPU guidance in this model card:

• short text: about <= 32 tokenizer tokens
• 33-63 tokens: gray zone, benchmark your workload
• >= 64 tokens: not short for this recommendation
• low batch: batch_size = 1
• batch_size = 2-4: gray zone, benchmark your workload
• batch_size >= 8: not low batch for this recommendation

Practical CPU rule:

• Prefer this fp16 repo for batch_size = 1 and about <= 32 tokens
• Prefer the canonical fp32 repo once batch size or sequence length grows materially

Variant	Device	Threshold	F1	Precision	Recall	Throughput ex/s	Size
Full fp32	GPU	0.4	0.9704	0.9647	0.9762	57.40	514 MB
fp16	GPU	0.4	0.9704	0.9647	0.9762	224.14	257 MB
Full fp32	CPU	0.4	0.9704	0.9647	0.9762	31.27	514 MB
fp16	CPU	0.4	0.9704	0.9647	0.9762	45.80	257 MB

Small PPSN regression suites with fp16 matched the full model in this workspace:

• User raw F1: 0.8000
• QA v6 validated F1: 0.6667
• QA v8 F1: 0.7385

Tradeoff

• Roughly half the model size vs the fp32 checkpoint
• Same measured PPSN quality as the fp32 release in these tests
• Faster GPU inference on the AMD ROCm setup used here
• Faster CPU inference than the fp32 checkpoint on the current low-batch end-to-end path
• In a batched CPU forward matrix, fp16 became slower than fp32 once batch size and sequence length increased; see eval/runtime_matrix_cpu_fp32_vs_fp16_compact.md
• The int8 release is still the highest-throughput CPU option, but it gives up more PPSN quality

Portfolio Comparison

Updated: 2026-03-16.

Use this section for the fastest public comparison across the temsa PII masking portfolio.

• The first core table only includes public checkpoints that ship both comparable q8 accuracy and q8 CPU throughput.
• The first PPSN table only includes public artifacts that ship comparable PPSN accuracy and CPU throughput.
• Missing cells in the archive tables mean the older release did not ship that metric in its public bundle.
• DiffMask rows use the reconciled clean_single_pass harness that matches the deployed runtime.
• GlobalPointer rows use the public raw-only span-matrix release bundle and its packaged q8 ONNX artifact.
• The same content is shipped as PORTFOLIO_COMPARISON.md inside each public model repo.
