Multi Agents with Different Brains (Qwen or Gemma)

With 128GB of Unified Memory and the M5 Max's 614GB/s bandwidth, you have a "Super-Workstation" capability. Running these two models simultaneously is the most efficient way to use your hardware.

To maximize the "Intelligence per Second," you should split your roles based on Computational Weight vs. Creative Fluidity.

Here is the optimal "Brain Assignment" for your agent swarm:

  1. The Coordinator (The "Boss")

  2. Brain: Qwen 3.5 122B (MoE)

  3. Why: The Coordinator must understand complex instructions, manage the state of other agents, and evaluate if a task is "complete." A 31B model can often lose the thread of a multi-step plan. Qwen 122B has the high-level logic to act as the "System Architect."

  4. Task: Breaking down the prompt, routing tasks to the Writer/Inspirer, and doing the final Quality Assurance (QA).

  5. The Historian (The Lore Keeper/Memory)

  6. Brain: Qwen 3.5 122B (MoE)

  7. Why: This is the most critical role for long-form work. The Historian needs to cross-reference facts (e.g., "In chapter 2, the watch was broken, but the Writer just said it chimed"). Smaller models like Gemma 31B have shorter "effective" logic spans and might miss subtle contradictions in a 100k-token lore file.

  8. Task: Managing the RAG (Retrieval-Augmented Generation) database and checking every output against the "World Truth."

  9. The Writer (The Prose Generator)

  10. Brain: Gemma 4 31B

  11. Why: You want speed and vibe here. Gemma 4 is tuned for incredible stylistic flow. On your M5 Max, Gemma 31B will likely hit 50-60+ tokens per second. This allows the agent to "draft" 1,000 words in seconds. If the prose is a bit "fluffy," the Qwen 122B Coordinator will fix it in the next step.

  12. Task: Taking the plot points and turning them into sensory, descriptive narrative or dialogue.

  13. The Plot Inspirer (The Brainstormer)

  14. Brain: Gemma 4 31B

  15. Why: Brainstorming requires "creative entropy"—the ability to throw 20 ideas at the wall to see what sticks. Gemma 31B is perfect for this because it is fast enough to generate 10 different versions of a plot twist in the time it takes Qwen 122B to generate one.
  16. Task: Rapid-fire ideation, "What if?" scenarios, and character name generation.

The Hardware Math (128GB Memory Allocation)

To run both without swapping to the SSD (which would kill your speed), use these quantizations:

  1. Qwen 3.5 122B (Q4_K_M or Q5_K_S): Takes up roughly 72GB – 80GB.
  2. Gemma 4 31B (Q8_0 or Q6_K): Takes up roughly 22GB – 28GB.
  3. KV Cache (The "Context"): You need at least 15GB – 20GB reserved for the "Short Term Memory" of all agents combined.

Total: ~115GB - 120GB. This fits perfectly within your 128GB envelope, leaving a bit for macOS and your Hermes/Docker overhead.

The Workflow Loop (How it looks in Hermes)

  1. User: "Write a story about a time-traveling watchmaker."
  2. Coordinator (Qwen 122B): "Plot Inspirer, give me 3 twists. Historian, verify the rules of time travel for this world."
  3. Plot Inspirer (Gemma 31B): (Instantly) "1. He is his own grandfather. 2. The watch eats memories. 3. The watch is a bomb."
  4. Historian (Qwen 122B): "Twist 2 is consistent with our established lore."
  5. Writer (Gemma 31B): (Blazing fast) Writes 500 words of the scene.
  6. Coordinator (Qwen 122B): Reviews the prose, fixes a logical error in the watch's gear movement, and presents the final text to you.

Recommended Tooling

Since you are driving this through Hermes Agent in Docker:

  • Set your Ollama to keep both models "loaded" by setting the OLLAMA_KEEP_ALIVE to -1.
  • In your Hermes config, define two separate providers:
    • logic_provider -> llama3.3:70b (or Qwen 122B)
    • creative_provider -> gemma4:31b
  • In your agent definitions, assign the logic_provider to the Coordinator and Historian, and the creative_provider to the Writer and Inspirer.
