reasongraph-extractor-qwen3-0.6b

One small LLM for the three reasongraph extraction tasks -- causal cause/effect/signal spans, contradiction detection, and entity extraction -- from a single LoRA adapter over Qwen/Qwen3-0.6B, selected by a task tag and returning strict JSON. This is the conflict-capable, llama.cpp-servable variant: unlike the qwen3.5 extractor, this base runs in llama.cpp today, so it is the model behind reasongraph's self-hosted FineTunedConflictResolver.

  • Method: LoRA (r=16, alpha=32, dropout 0.05, all linear layers, 3 epochs, completion-only loss), merged to fp16.

Tasks & prompt format

Prompt with a bare task tag (no chat template) and greedily decode the JSON completion.

Tag Input Output
[causal] [causal] <sentence> `{"causal": true
[conflict] [conflict] existing: <fact A>\nnew: <fact B> `{"conflict": true
[entities] [entities] <sentence> {"entities": ["...", ...]}

llama.cpp serving (conflict resolver)

llama-server -m qwen3-0.6b-multitask-Q4_K_M.gguf -t 4 -c 2048

Per-pair conflict via /v1/completions (or /completion), temperature 0, cache_prompt, with a JSON grammar so the reply is strict yes/no:

root ::= "{\"conflict\": \"" ("true" | "false") "}"

(exact grammar used in production: root ::= "{" ws "\"conflict\"" ws ":" ws ("true"|"false") ws "}"). Prompt = "[conflict] existing: {existing}\nnew: {new}". Served figures: served Q4_K_M conflict F1 0.851 at 141 ms/pair (median, 4 threads), p90 162 ms (H3).
