Agentic Stack runs Fable 5, GPT 5.6
AI developer Avid (@Av1dlive) shared a workflow to run Anthropic's Claude Fable 5 and OpenAI's GPT 5.6 Sol concurrently in a single execution loop. Using Claude Code with the Agentic Stack and ZTK proxy, developers can combine Fable 5's reasoning with GPT 5.6's speed while preserving context and reducing token costs.
Orchestrating multiple frontier models in real-time, hybrid loops is the future of agentic workflows, moving past single-model dependency to exploit specific model strengths dynamically.
* Hybrid Efficiency: Combining Claude Fable 5's reasoning with GPT 5.6 Sol's coding speed allows developers to achieve results neither model could produce as efficiently alone.
* Unified Memory: The Agentic Stack's portable `.agent/` folder prevents "tool amnesia," maintaining a consistent context as the workflow hops between different models.
* Token Cost Reduction: Utilizing the `ztk` CLI proxy filters terminal noise, saving up to 78% in token costs, which is essential for multi-agent loops running premium frontier models.
* Agility in Model Rollouts: This setup demonstrates the need for modular, model-agnostic developer tooling that can quickly adapt to new model releases and access windows.
