Debug Mode for LLMs in vLLora

Summary

LLMs behave like black boxes. You send them a request, hope the prompt is right, hope your agent didn't mutate it, hope the framework packaged it correctly — and then hope the response makes sense. In simple one-shot queries this usually works fine. But when you're building agents, tools, multi-step workflows, or RAG pipelines, it becomes very hard to see what the model is actually receiving. A single unexpected message, parameter, or system prompt change can shift the entire run. Today we're introducing Debug Mode for LLM requests in vLLora that makes this visible — and editable. Here’s what debugging looks like in practice: vLLora now supports Debug Mode for LLM requests. When Debug Mode is enabled, every request pauses before it reaches the model. Debug Mode works by inserting breakpoints on every outgoing LLM request, allowing you to inspect, edit, or continue execution. You can: Inspect the exact request Edit anything Continue execution normally This brings a familiar software-engineering workflow ("pause -> inspect -> edit -> continue") to LLM development. Why We Built This​ If you've built anything beyond a simple chat interface, you've likely hit one of these: Silent tool-call failures (wrong name / bad params / malformed JSON) Overloaded or corrupted context / RAG input leading to hallucination or truncation Error accumulation and state drift in long or multi-step workflows Lack of visibility: standard logs rarely show the actual request sent to the model It is difficult to fix these issues without proper observability. Debug Mode changes that. What Happens When a Request Pauses​ Here's what it looks like when vLLora intercepts a request right before it's sent: You get a real-time snapshot of: The selected model Full message array (system, user, assistant) Parameters like temperature or max tokens Any tool definitions Any extra fields and headers your framework injected This is the full request payload your application is about to send — not what you assume...
