# char-rp-gguf — dedicated GGUF character-RP seat on fv-ml1 GPU 0, REPLACING the
# broken ms32-24b-angel NVFP4 serve (garbage output — bad self-quant W4A4).
#
# Two co-located llama.cpp (llama-server) instances on GPU 0, served alongside the
# 35B-A3B heretic `gen` (qwen36-27b-aeon stack, :8015):
#
#   llama-charrp (:8016, gateway char-rp) — TheDrummer Magidonia-24B-v4.3 Q6_K.
#       Magistral (Mistral) dark-romantasy RP tune. NON-thinking PROSE seat: elite
#       literary prose, zero refusal, ~65 tok/s, precise POV/instruction adherence.
#
#   llama-charrp-reasoning (:8018, gateway char-rp-reasoning) — ArliAI QwQ-32B-RpR-v4 Q5_K_M.
#       QwQ reasoning RP tune whose reasoning DATA was generated with QwQ-ABLITERATED
#       → it does NOT re-censor in the think phase (the exact failure mode that killed
#       the Pantheon/DeepSeek-distilled reasoners: they reason themselves into refusals
#       inside <think>). llama.cpp MANAGES QwQ reasoning natively: --reasoning on
#       surfaces the trace in reasoning_content (clean prose in content, no <think>
#       leak), --reasoning-budget caps the chain-of-thought. ~50 tok/s @ Q5_K_M.
#
# WHY GGUF/llama.cpp (not vLLM NVFP4): sidesteps BOTH traps that killed the Angel serve
# — the vLLM NVFP4 self-quant breakage AND the Mistral-tokenizer/vision crash. llama.cpp
# handles Mistral + QwQ tokenizers natively. NEVER Ollama (banned fleet-wide).
#
# WHY TWO models (not one): no single dense 24-32B is BOTH an elite non-thinking prose
# seat AND a clean managed-reasoning seat on llama.cpp. Magidonia's Magistral [THINK]
# discipline is loose (won't reliably close [/THINK] on substantive reasoning → prose
# bleeds into reasoning_content, content empties); Cydonia-R1's <think> is emergent, so
# llama.cpp can't manage/cap it → runaway CoT that never reaches prose. QwQ's template
# opens <think> natively → llama.cpp manages+caps it. So: best-of-breed per seat.
# ONE-MODEL FALLBACK (consistent Mistral style, lighter reasoning): point both services
# at Magidonia via CHARRP_REASONING_MODEL in .env and blank CHARRP_REASONING_EXTRA_*.
#
# ALTERNATE prose model: PaintedFantasy-v4.1-24B (also Magistral, more literary flair
# but looser POV adherence) — set CHARRP_MODEL in .env. All candidate GGUFs are
# pre-pulled to /tank/aimodels/llm/rp/.
#
# VRAM (GPU 0, co-resident with gen ~38G): Magidonia Q6 ~19G + RpR-v4 Q5 ~23G + KV/
# compute ~6-8G = ~85-88G / 97G (~9-12G margin). Keep ctx modest; drop CHARRP_*_CTX
# to 8192 in .env if warmup bites. depends_on sequences char-rp first.
#
# API auth: blank (LAN-internal on the GPU host; matches API_KEY= in the AEON stack /
# gateway VLLM_API_KEY). llama-server ignores the gateway's api_key when none is set.
#
# All tunables live in .env — edit that, not this file.

    # ⚠️ CUSTOM llama.cpp build (master 6eddde0 + unmerged PR #25544). Needed for two reasons:
    # (1) recent master parses Qwen3.6's native qwen3_coder tool-call format (stock b8840 predates it —
    #     the <tool_call><function=..><parameter=..> XML is Qwen3.5/3.6-native, NOT an OpenHands quirk);

    #     NEO-CODE shows 0.0 runaway (R36 gate), but keep it. DO NOT revert to stock until #25544 merges.
    # Build recipe + why + rollback: ./llamacpp-custom/README.md.
