I can’t believe I would consider this. I have been on Claude 20x Max plan for 8 months now. 52B token later, I am actually considering switching. But we know Anthropic will likely release something that will beat Astra. And GPT-7 will beat Anthropic model again. It’s not simply switching the model, it’s the harness. For example, I can’t simply migrate 20 repo developed by Claude Code to Codex. Sure Astra is intelligent enough to optimize my CC repos for Astra. But switching and re-optimizing my repos every few months involves a high switching cost. I am aware of OpenCode and DeepSeek harness. My questions: Has anyone used an open-source harness with multiple model providers? What’s your setup to sure cohesive workflow between different models? Can you bring different subscriptions into open-source harness? For example $100 Anthropic and $20 OpenAI + API call to GLM5.3 Any ideal IDE for such a model agnostic harness? Or doesn’t matter? UPDATES I have built many bundles of skills, multi-agentic workflows that activate on schedule in Claude Code. So migration would take a lot of re-working those workflows to Codex. submitted by /u/Fr33-Thinker
