| # Trinity Mini Modern — production step 225 | |
| LoRA adapter from optimizer step **225** of the fresh production run started on | |
| 2026-09-15. This is an adapter, not a merged standalone model. | |
| - Base: `arcee-ai/Trinity-Mini` | |
| - Base revision: `cdb81e8130815fec299cccc8f8700004b8366e1e` | |
| - W&B run: https://wandb.ai/kragelund/prime-rl/runs/049e3171c8514164ae104ddae4dcc14c | |
| - Rank 128, alpha 256; targets `q_proj`, `k_proj`, `v_proj`, `o_proj`. | |
| - Source adapter was preserved outside the run's rolling checkpoint cleanup. | |
| ## Important: optimizer state is unavailable | |
| **This repository does not contain the step-225 optimizer/trainer state and is | |
| not a fully resumable training checkpoint.** The run retains only its last two | |
| rolling trainer checkpoints plus every 100th step. By the time this upload was | |
| requested, the step-225 trainer checkpoint had been removed. Its separately | |
| preserved adapter remains intact. Do not substitute optimizer state from another | |
| step and call that an exact step-225 resume. | |
| The adapter can be used for inference or as a warmstart with a new optimizer. | |
| ## Files and configuration | |
| - `adapter_config.json`, `adapter_model.safetensors`: original step-225 adapter. | |
| - `configs/rl.toml` and `configs/fresh-20260915.toml`: ordered launch config layers. | |
| - `configs/resolved-trainer.toml`, `configs/resolved-orchestrator.toml`: runtime | |
| trainer/orchestrator configurations written by PRIME-RL. | |
| - `configs/inference-preflight.toml` and `configs/start-optimized-inference.sh`: | |
| inference config plus launch overrides. The script's overrides are necessary | |
| to interpret the actual port, LoRA target modules and compilation setting. | |
| - `manifest.json`: provenance, file sizes and SHA-256 checksums. | |
| Deployment-specific paths and endpoint addresses are historical references. | |
| Credentials are not included. Runtime source patches and the original dependency | |
| environment are not bundled, so config files alone are not a complete software | |
| reproduction package. | |
