This paper revisits the reasoning patterns of Long and Short CoT models, observing that the Short CoT patterns offer concise reasoning efficiently, while the Long CoT patterns excel in challenging scenarios where the Short CoT patterns struggle. To enable models to leverage both patterns, we propose Question-Free Fine-Tuning (QFFT), a fine-tuning approach that removes the in","authors_text":"Benyou Wang, Fei Yu, Junxiao Xu, Ke Ji, Lifeng Shang, Wanlong Liu, Wenyu Chen, Yan Xu, Yasheng Wang, Yukang Lin","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2025-06-15T14:21:28Z","title":"QFFT, Question-Free Fine-Tuning for Adaptive Reasoning"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2506.12860","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:e8d92b693023ffca8b55a00c2fcd1bbe1865ce42a68dfaa4e1f8f5a2fdf930c2","target":"record","created_at":"2026-07-05T11:22:01Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"dec8d7c9fcfbec4088d7675637be06ac695f3ff8912d9351809f1e325b310ca9","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2025-06-15T14:21:28Z","title_canon_sha256":"52721d37ee797a1e66febffd272604930a210d5dbac179636c19fd4bd3e2cdf8"},"schema_version":"1.0","source":{"id":"2506.12860","kind":"arxiv","version":1}},"canonical_sha256":"2bed4c52188c89b5607c3ac842ee205208e710e75bdf7f9e1882f5710b829f89","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2bed4c52188c89b5607c3ac842ee205208e710e75bdf7f9e1882f5710b829f89","first_computed_at":"2026-07-05T11:22:01.499483Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:22:01.499483Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"/rj7dIKNwPMFbBeE8wpgHqT9OaM0gMXxT00rZUlTQVeeNbkfXVyuadkg21C8M2vikamLtZEmYB+Jl1vi1WahCw==","signature_status":"signed_v1","signed_at":"2026-07-05T11:22:01.499920Z","signed_message":"canonical_sha256_bytes"},"source_id":"2506.12860","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e8d92b693023ffca8b55a00c2fcd1bbe1865ce42a68dfaa4e1f8f5a2fdf930c2","sha256:0003435c1e211e959a7f81f4376d04bf52fa77dd26a590c06915baaba8fb3fd5"],"state_sha256":"c185c9d5e1ff742a5cd5baacb48fb8c39975b6f24c2d70ebb966e995fe4a4045"}
