onPanda is an open-source interface for inspecting and steering LLMs and agents at the token level. Select a generated token, inspect alternatives, replace it or edit freely, then continue generation from that point. Branch generations, inspect reasoning and tool calls, and annotate model and agent trajectories in one interactive workspace.

Could you build this?
Partial The UI for selecting, replacing, and branching tokens is vibe-codeable, but token-level steering requires an inference backend that exposes logprobs and lets generation resume from an edited prefix. That needs real LLM serving knowledge.
What it would actually take: The stack would be a web frontend with a backend running open-weight models through vLLM, llama.cpp, or Transformers, which expose per-token logits and support prefix-conditioned continuation. The hard parts are efficient KV-cache reuse when branching and making the agent and tool-call traces coherent. This needs ML inference experience and GPU resources for a usable version.
