# meromero-charrp — MeroMero-v2 char-rp prose seat (ana-ml2 GPU0)

The **non-thinking, multimodal** RP prose seat. Serves the LiteLLM `char-rp` alias.

- **Model:** `G4-MeroMero-v2-31B-NVFP4A16` (Gemma-4-31B, home-quantized weight-only NVFP4A16).
- **Host/GPU:** ana-ml2, GPU0 (co-located with `gen` / vllm-aeon-gen).
- **Port:** :8016 → LiteLLM `char-rp`.
- **Context:** 256K (`--max-model-len 262144`). Gemma-4 uses sliding-window attention → KV-efficient, ~2× concurrency at full context.
- **Vision:** enabled (image + text). `preprocessor_config.json` was materialized from the model's own `processor_config.json` (`Gemma4ImageProcessor`); audio is config-declared but weightless.
- **Tuning:** `.env` — `MEROMERO_GPU_MEM_UTIL=0.52` (leaves ~4.6 GB GPU0 headroom), `MEROMERO_MAX_MODEL_LEN=262144`, `MEROMERO_GPU_ID=0`.

Replaces the retired **char-rp-gguf** (Magidonia-24B GGUF / llama.cpp) seat. The quant pipeline
lives in `ana-ml2:/tank/aimodels/meromero-v2-nvfp4-work/`.

## Deploy

```bash
scripts/deploy-stack.sh ana-ml2 meromero-charrp     # diffs vs live, prompts y/N
# on host: cp .env.example .env; docker compose up -d
