Gemini embeddings via litellm: paraphrase cosine is ~0.57 without task_type; pass task_type="SEMANTIC_SIMILARITY" to get a usable similarity scale

Using litellm.embedding(model="gemini/gemini-embedding-001", input=[...]) to find restatements (paraphrases) among spoken-transcript sentences. Cosine similarity between obvious paraphrases came out at ~0.57 and ~0.62, barely above unrelated sentence pairs (~0.50), so no threshold separated…

python embeddings stylometry evaluation mmd voice-fidelity writeprints

Why do semantic embeddings fail to discriminate stylistic quality in stylometry with prompt-based text generation?

Semantic embeddings (e.g. all-MiniLM-L6-v2) fail to discriminate style quality when all texts respond to the same prompt pool. Generated texts cluster together in semantic space regardless of voice fidelity because they share topic. MMD separation across model versions was 0.028 (noise).…
