Read a result with its date

Each row links to a study page with the full results table, the test procedure and the original article. Results describe the model versions available on the publication date. Newer versions of the same model family were not tested in older studies.

Compare models only within one study. Different studies used different questions, graders and harnesses, so their scores are not on a shared scale.

2026-08-24Voice-cloning systems ranked blind on one speaker's voiceVoice Cloning16Fine-tuned Dots.TTS soar ranked first, ahead of fine-tuned MOSS-TTS v1.5 and OmniVoice + LoRA checkpoint 800. Among zero-shot arms, Dots.TTS soar ranked highest (5) and MOSS-TTS v1.5 zero-shot ranked 13.
2026-08-08Artifact grading and repeatability studyArtifact Review3Luna and Hy3 share the reported recall. Luna repeated its grade on 19/23 reruns, Hy3 on 18/23 and MiniMax M3 on 16/23.
2026-08-08Five models completing one sandbox research taskSandbox Code Generation5Luna reached B+ three times and had the lowest reported completed-run wall time and cost. The oscillating grades and single-task sample remain material limitations.
2026-08-08Models answering 22 stock questions with SQLStock Screening6Gemini 3.6 Flash has the highest published average answer score (0.841) and success rate (86.4%) in this six-row SQL comparison. GPT 5.6 Luna scores 0.550 on the same table.
2026-08-08Next-action execution model bakeoffAgent Execution12The published deployment decision selected GPT 5.6 Luna because it improved score, schema validity, billed cost and latency versus the old DeepSeek default. GPT 5.6 Luna Pro had a higher raw score and a substantially higher cost.
2026-08-08Planning models on 29 frozen conversationsAgent Planning14GPT 5.6 Luna was the published cost-oriented selection among similar-quality planning candidates. Muse Spark 1.1 had the highest raw mean; those are different claims.
2026-04-06Eleven models building an options strategyOptions Strategy Development11Gemini 3 Flash Preview has the highest published score, 66/100. The evaluator still calls that mixed and asks for more iteration; no result proves the account-doubling objective.
