Introduction of FIM-Mid-8B

Model Details of FIM-Mid-8B

FIM-Mid-8B

FIM-Mid-8B is the mid-trained checkpoint of the FIM 8B pipeline: Qwen3-8B after FIM mid-training, before agent post-training. Post-training this checkpoint on SWE-Lego trajectories produces TIGER-Lab/FIM-8B .

Model

Local path: models/FIM-Mid-8B/ (checkpoints are gitignored; do not commit them).

  • Base model: Qwen/Qwen3-8B
  • FIM mid-training: train/FIM_Midtrain_8B.yaml (AdamW, lr 1.0e-5 , cosine schedule, warmup ratio 0.1 , weight decay 0.05 , one epoch, sequence length 32768 , bf16)
  • Post-training: none — see TIGER-Lab/FIM-8B for the post-trained agent model
Serve with vLLM

Ships the native Qwen3 40960 context (the yarn extension to 163840 was applied at post-training time); no overrides needed:

Post-training

To reproduce FIM-8B, run SWE-Lego trajectory SFT from this checkpoint (LLaMA-Factory, full fine-tuning, lr 1.0e-4 , 4 epochs, cutoff 131072 with yarn rope scaling, qwen3_nothink template, error masking enabled).
