Physics-R1 — Seed 23 (HF safetensors)

Project Page | Paper | Code | Training corpus

The Physics-R1 paper checkpoint for the seed-23 row of Table 2 (canonical step 60). Fine-tune of Qwen3-VL-8B-Thinking on the audited PhysR1Corp (2,268 closed-form physics problems) via full-parameter FSDP1 GRPO with binary correctness reward.

This seed has the highest individual PhysOlym-A score (28.2) among the paper's three seeds.

This is the easy-to-use HF safetensors release. For the original verl FSDP-sharded archive, see physics-r1-seed23-canonical-step60-fsdp.

Quickstart

from transformers import AutoModelForImageTextToText, AutoProcessor
import torch

model = AutoModelForImageTextToText.from_pretrained(
    "shanyangmie/physics-r1-seed23",
    dtype=torch.bfloat16,
    device_map="auto",
    trust_remote_code=True,
)
processor = AutoProcessor.from_pretrained(
    "shanyangmie/physics-r1-seed23",
    trust_remote_code=True,
)

For evaluation against the paper's benchmark, see PhysOlym-A and the code release.

Performance (paper Table 2, seed-23 row)

Eval	Physics-R1 (this checkpoint)	Base Qwen3-VL-8B-Thinking	Δ
PhyX-mini	77.9	73.7	+4.2
PhyX-3k	76.6	74.4	+2.2
PhysReason	43.4	23.9	+19.5
PUB-OE	30.9	35.3	-4.4
OlympiadBench-Physics	48.0	39.3	+8.7
PhysOlym-A	28.2	8.0	+20.2

Scoring: problem-level liberal Sonnet-as-judge (every subpart of a multi-part problem must be correct). The 3-seed mean across {42, 17, 23} is the paper's headline (+18.9 pp on PhysOlym-A).

Other seeds (HF safetensors mirrors)

Seed	HF safetensors mirror	FSDP archive
42	`shanyangmie/physics-r1-seed42-v4-step60`	`...-seed42-v4-step60-fsdp`
17	`shanyangmie/physics-r1-seed17`	`...-seed17-canonical-step63-fsdp`

Training recipe

Base model: Qwen/Qwen3-VL-8B-Thinking
Algorithm: GRPO (verl 0.6.1, full-parameter FSDP1 — actor.strategy=fsdp, not fsdp2)
Reward: binary correctness, per-subpart Sonnet judge with problem-level AND aggregation (see paper §3.2)
Data: shanyangmie/physr1corp — 2,268 audited closed-form problems
Seed / step: 23 / 60
Hardware: 4×H200 (FSDP1 4-way sharded)

Full hyperparameters in paper Appendix.
