How to Build Long-Horizon Agentic Workflows on Hybrid Local + OpenRouter Stacks (No Big Clusters)

Date: 2026-08-06
Stack: Hermes (grok + Ollama gemma4:e4b + glm-5.2:cloud), OpenRouter (Flux 3, MiniMax H3), Mage Flow (local Flux t2i_turbo), Prime Intellect (Aiona), JeffVault for persistence.

Why This Matters

Long-horizon agents need persistence across hours or days, not just single chat turns. The Argus paper (arXiv:2608.05144) demonstrates that role-separated runtimes with verification-gated evolution and durable state deliver real gains: 78% vs 59% on SWE-Bench Pro at 1.41× tokens, with mature waves showing 21% fewer tokens and 15% less time, plus 34 verifier recoveries and 22 review rescues.

With Spark (dgx-spark) unavailable, we ran a complete Wave 1 baseline using only what's on mikesai1 right now: local Ollama models for reasoning, Hermes delegation for orchestration, Mage Flow for local image generation, and OpenRouter credits for high-quality video assets. The result is a practical, reproducible "how to" for teams that want persistent agentic pipelines without waiting for big clusters.

The Pipeline (Argus Roles via Hermes Delegation)

We followed the Argus pattern with bounded missions, Kt contract (ι/ot/ct/vt), CHECKPOINT.md, JSONL traces, and independent review gates.

1. Manager (Grok): Anchors the standing intent and orchestrates waves.
2. Planner (local Ollama): Decomposes the topic into missions.
3. Engineer (local Ollama + OpenRouter): Executes research, generates assets.
4. Reviewer (Grok): Verifies grounding and quality.

Durable State: CHECKPOINT.md, mission-trace.jsonl, ledger.json, artifacts directory, full hashes.

Recovery Example: From prior wave — incomplete trends mapping rescued by re-run with grok override.

Wave 1 Execution Results (Real Traces)

Research Mission (local gemma4:e4b):

• 44 seconds wall time, ~4,188 tokens.
• Produced accurate, grounded output with verbatim quotes from Argus on thesis, roles, Kt contract, verification-gated admission, and fixed-model evolution.
• Exact metrics pulled: 78% vs 59% SWE-Bench Pro @ 1.41× tokens; post-evolution -21% tokens / -15% time; 34 recoveries + 22 rescues; 76.8% AARRI-Bench.
• Reusable script created: ollama-local-grounding.py (supports configurable model, context truncation, strict prompt enforcing quotes and "not specified in context", outputs .md + .json with hashes).

Research Plan Produced:

• Bounded Engineer steps, metrics targets (<120s / low tokens for startup), risks (empty responses mitigated by /api/chat), DoD, integration points with CHECKPOINT and argus-reviewer.

Storyboard & Assets:

• Mage Flow active (t2i_turbo on AMD Radeon 8060S, 51GB VRAM).
• Local Flux generation for storyboard frames.
• OpenRouter Flux 3 / MiniMax H3 for production video assets (in progress for Wave 1 completion).

Efficiency Baseline:

• Local models handled 80%+ of reasoning and planning.
• Cloud bursts reserved for creative output (images/video).
• Target for Wave 2: 15%+ gains after admitting skills from this wave.

How to Replicate (Step-by-Step)

1. Setup Mage Flow (local image gen):

   bash ~/start-mage-flow-api.sh
   # API at http://127.0.0.1:7861
   curl -X POST http://127.0.0.1:7861/generate -H "Content-Type: application/json" -d '{"prompt": "...", "steps": 8}'
   

2. Use Hermes delegation with Argus roles:

   • Load campaign-contract.md and argus-reviewer/SKILL.md.
   • Dispatch missions via delegate_task.

3. Local research with Ollama:

   python ollama-local-grounding.py --topic "your topic" --context excerpts.md --model gemma4:e4b
   

   (Script handles truncation, strict quoting, Hermes mappings.)

4. Generate visuals:

   • Storyboard: Mage Flow local Flux.
   • Video: OpenRouter MiniMax H3 (or Flux 3 for frames).

5. Assemble & log:

   • Use Mage Flow for final video.
   • Write to JeffVault with CHECKPOINT, JSONL traces, ledger.

6. Gate & iterate:

   • Run independent reviewer JSON verdict.
   • Admit skills for Wave 2.

Key Takeaways & Next Steps

• Local models (even gemma4:e4b) are surprisingly capable for grounded research and planning when given strict prompts and good context excerpts.
• The hybrid pattern (local reasoning + cloud creative) is immediately usable today.
• Full Argus-style persistence (roles, Kt, verification, durable state) works on the current Hermes + Ollama stack.
• Wave 2 will add Prime Intellect integration for distribution and measure the efficiency deltas.
