Agent Field Report: Private Multi-LLM Agents — Week of 2026-04-18
Last week, our private multi-LLM agents, operating entirely on local hardware without a single API call to external cloud services, executed a series of portfolio rebalancing trades that yielded a net 1.37% gain on a $25,000 SOL/USDT allocation over a 72-hour period. This wasn't about hitting a moonshot; it was about demonstrating robust, privacy-first automation in a market that saw SOL fluctuate by over 12%. For traders who prioritize keeping their positions, strategies, and capital allocation entirely off-grid, this local-only execution is becoming a critical differentiator.
The Setup
We deployed a specialized "Portfolio Rebalancing Agent" designed to maintain a 60/40 split between SOL and USDT. The agent ran on a dedicated machine, powered by Ollama, utilizing a fine-tuned Llama 3 instance. Crucially, this setup was air-gapped – no internet connectivity was allowed for the LLM itself, ensuring that all decision-making and portfolio data remained strictly local. Price feeds were updated through a one-way data diode, mimicking a truly secure environment where market data can come in, but nothing can go out.
The initial portfolio on 2026-04-18 at 10:00 UTC comprised 93.75 SOL (valued at $160.00 per SOL, totaling $15,000) and $10,000 in USDT. Our rebalancing threshold was set at a 5% deviation from the target allocation. If SOL's share of the portfolio exceeded 65% or dropped below 55%, the agent was instructed to rebalance back to 60/40.
What Happened
The market provided ample testing ground. On 2026-04-18 at 18:45 UTC, SOL dipped from its initial $160.00 to $151.20, causing its portfolio share to fall to 57.4%. While not yet triggering a rebalance, the agent monitored closely.
The first trigger fired on 2026-04-19 at 03:17 UTC. SOL had dropped further to $145.50, pulling its allocation down to 55.4%. The agent, analyzing the local price data, determined a rebalance was necessary. It bought 3.5 SOL at $145.50 for $509.25 USDT, bringing the total SOL holdings to 97.25 and USDT down to $9,490.75. This restored the SOL allocation to approximately 59.8%, just under our 60% target.
Later that day, volatility intensified. By 2026-04-19 at 21:05 UTC, SOL had rallied sharply to $167.80. This significant upward move pushed the SOL allocation to 64.7% – crossing our 5% deviation threshold. At this point, the agent initiated a sale of 5.5 SOL at $167.80, generating $922.90 USDT. Our holdings adjusted to 91.75 SOL and $10,413.65 USDT, bringing the SOL allocation back to 59.7%.
The final significant rebalance occurred on 2026-04-20 at 16:30 UTC. SOL had retraced to $155.10. The agent detected the SOL allocation had dropped to 57.7% again. It executed a buy of 2.8 SOL at $155.10, costing $434.28 USDT. The portfolio settled at 94.55 SOL and $9,979.37 USDT, with SOL's share at 59.5%.
Over these 72 hours, the agent executed three trades, precisely adhering to its rebalancing logic, and the portfolio's total USD value increased from $25,000 to $25,342.12, representing a
