  # Secondary: vllm-mlx (OpenAI-compatible local backend, 25–50% faster than Ollama on Apple Silicon)
  # Evaluation results (EuroMLSys '26 / M3 Ultra benchmarks):
  #   - 21–87% higher throughput than llama.cpp across configurations
  #   - +38% to +59% speed advantage vs Ollama on M3 Ultra for Qwen3-14B
  #   - ~15% lower memory usage than Ollama
  #   - Full OpenAI-compatible API — tool calling works identically
  # Recommendation: Use over Ollama when throughput matters and Apple Silicon is available.
  #   Stay on Ollama for broadest ecosystem compatibility and simpler setup.
  # To enable: start vllm-mlx server (`python -m vllm.entrypoints.openai.api_server
  #   --model Qwen/Qwen2.5-14B-Instruct-MLX --port 8000`) then set enabled: true.

# ── Capability-Based Fallback Chains ────────────────────────────────────────
# When a model doesn't support a required capability (e.g., vision),
# the system falls back through these chains in order.

fallback_chains:
  # Vision-capable models (for image understanding)
  vision:
    - llama3.2:3b          # Fast, good vision
    - qwen2.5-vl:3b        # Excellent vision, small
    - llava:7b             # Classic vision model
    - moondream:1.8b       # Tiny, fast vision
  
  # Tool-calling models (for function calling)
  tools:
    - timmy                # Fine-tuned Timmy (Hermes 4 14B + LoRA) — primary agent model
    - hermes4-14b          # Native tool calling + structured JSON (AutoLoRA base)
    - llama3.1:8b-instruct # Reliable tool use
    - qwen2.5:7b           # Reliable tools
    - llama3.2:3b          # Small but capable
  
  # General text generation (any model)
  text:
    - qwen3:30b
    - llama3.1:8b-instruct
    - qwen2.5:14b
    - deepseek-r1:1.5b
    - llama3.2:3b

  # Creative writing fallback chain
  # Ordered preference: Morrowind-tuned Dolphin → base Dolphin 3 → Qwen3 (primary)
  # Invoke when Qwen3-14B adds unwanted caveats on journal/lore/NPC tasks.
  creative:
    - timmy-creative    # dolphin3 + Morrowind system prompt (Modelfile.timmy-creative)
    - dolphin3          # base Dolphin 3.0 8B (uncensored, no custom system prompt)
    - qwen3:30b         # primary fallback — usually sufficient with a good system prompt

  # ── Complexity-based routing chains (issue #1065) ───────────────────────
  # Routine tasks: prefer Qwen3-8B for low latency (~45-55 tok/s)
  routine:
    - qwen3:8b              # Primary fast model
    - llama3.1:8b-instruct  # Fallback fast model
    - llama3.2:3b           # Smallest available

  # Complex tasks: prefer Qwen3-14B for quality (~20-28 tok/s)
  complex:
    - qwen3:14b             # Primary quality model
    - hermes4-14b           # Native tool calling, hybrid reasoning
    - qwen3:30b             # Highest local quality
    - qwen2.5:14b           # Additional fallback

# ── Custom Models ───────────────────────────────────────────────────────────
# Register custom model weights for per-agent assignment.
# Supports GGUF (Ollama), safetensors, and HuggingFace checkpoint dirs.
# Models can also be registered at runtime via the /api/v1/models API.
#
# Roles: general (default inference), reward (PRM scoring),
#        teacher (distillation), judge (output evaluation)

  #   path: deepseek-r1:1.5b
  #   role: reward
  #   context_window: 32000
  #   description: "Process reward model for scoring outputs"

# ── Agent Model Assignments ─────────────────────────────────────────────────
# Map persona agent IDs to specific models.
# Agents without an assignment use the global default (ollama_model).
agent_model_assignments: {}
  # Example:
  # persona-forge: my-finetuned-llama
