Showing deterministic & evidence-grounded autopsies generated from the real Revenant pipeline. When live open-weight LLM gateways (Gemma, Backboard, or local Ollama) are enabled, all three models run live side by side.

How to enable additional live open-weight LLM providers

Configure GOOGLE_API_KEY (Gemma 3 27B), BACKBOARD_API_KEY (Qwen3 / Llama-3.3 via Backboard), or OLLAMA_BASE_URL (local Ollama) in your environment and set LLM_ARENA_PROVIDERS in .env.local.
