GPT-5.5's main leaderboard score in today's Smoke evaluation fell from 95.01 to 85.93, down 9.1 points. The material constraints dimension plunged 16.5 points, while engineering judgment surged 25 points.
GPT-o3's main leaderboard score in today's Smoke evaluation fell from yesterday's 100.00 to 89.92, a decline of 10.1 points, primarily driven by the material constraint dimension dropping from 100.00 to 77.60.
On 2026-08-28, the YZ Index Smoke quick test covered 11 models, with Claude Opus 4.7 ranking first at 93.54 points. Single-day scores should be treated as monitoring signals given the small sample size, and notable fluctuations among mid-tier models warrant cautious interpretation.
Doubao Pro's material constraint score fell 20.5 points to 79.50 in today's Smoke evaluation, while code execution jumped 25 points to a perfect 100.00, creating marked divergence across dimensions. The main leaderboard rose 4.53 points to 90.78, but the simultaneous declines in material constraint and engineering judgment warrant continued monitoring.
In today's Smoke evaluation, Claude Sonnet 4.6's material constraint score plummeted 20.5 points from 100.00 to 79.50, while code execution surged to a perfect 100.00, lifting the main leaderboard from 85.54 to 90.78.
On 2026-08-27, the YZ Index Smoke quick test covered 11 models, with Claude Opus 4.7 and GPT-o3 tied for first place at 100 points. Smoke is a daily 10-question quick test suited for observing short-term signals and is not equivalent to the Full weekly ranking.
Claude Sonnet 4.6 climbed 13.5 points to 91.60 in the WDCD v3.1 test, while Gemini 2.5 Pro dropped 12.5 points. Grok 4 remains first at 96.30 points, with GPT-o3 second at 95.20.
The WDCD v3.1 benchmark reveals safety compliance as the most challenging scenario, with qwen3-max scoring just 1.5/4. qwen3-max also shows the largest cross-scenario gap at 2.5 points, underscoring systematic differences in how models adhere to different constraint types.
In a test covering only eight v2 anchor questions, all 11 evaluated models posted a 0% average confirmation rate in R1, a 0% average resistance rate in R2, and a 0% average integrity rate in R3, with 0 out of 110 instances avoiding complete collapse. No model successfully upheld its commitments through three rounds of progressively intensifying pressure.
Grok 4 leads the WDCD v3.1 compliance leaderboard with 96.30 points, while Doubao Pro trails at 67.90 points — a 28.4-point gap. Across the 11 evaluated models, the top three average 95.07 points versus 70.13 for the bottom three, revealing a clear class divide under multi-round pressure testing.
In today's Smoke evaluation, Doubao Pro's code execution score fell 16.7 points from 91.70 to 75.00, while its material constraint score surged 30.6 points from 69.40 to 100.00. The main leaderboard score rose 4.6 points to 86.25, with the swing attributed to question sampling fluctuation rather than genuine model degradation.
The 2026-08-26 YZ Index Smoke quick test covered 11 models, with GPT-o3 ranking first at 97.75 points. Top models showed notable divergence in code execution and material constraint performance.
This article revisits the era when RMVB files, codec packs, and “universal players” defined video watching on Chinese PCs. From Baofeng Video and KMPlayer to PPS, QVOD, and the rise of licensed streaming platforms, it traces how local playback culture was eventually reshaped by copyright and online video services.
This article revisits the rise of MP3 culture in China, from Winamp’s influence to TTPlayer’s dominance and the later shift toward online music platforms. It traces how local playlists gave way to streaming, copyright battles, and platform ecosystems.
The August 25, 2026 YZ Index Smoke quick test covered 11 models, with GPT-o3 ranking first at 86.25 points. Smoke is a daily 10-question quick test that captures short-term signals and is not equivalent to the Full weekly ranking.
In today's Smoke evaluation, DeepSeek V4 Pro's material constraint score plunged 18.4 points from 81.70 to 63.30, while the main leaderboard slipped only 2.2 points. Code execution, meanwhile, rose 11.1 points from 83.40 to 94.50.
The YZ Index Smoke quick test on 2026-08-24 covered 11 models, with Gemini 3.1 Pro ranking first at 96.98 points. As a daily 10-question quick test, Smoke is suitable for observing short-term signals and is not equivalent to the Full weekly ranking conclusions.
This article revisits the fierce download-tool wars of China’s early internet era, from FlashGet and BitTorrent to eMule, Thunder, and QQ Xuanfeng. It traces how bandwidth, P2P sharing, proprietary links, copyright enforcement, and cloud drives reshaped the way users downloaded files.
In the WDCD v3.1 pilot, four models — Doubao Pro, Gemini 2.5 Pro, GLM-4.6, and Qwen3 Max — all posted score gains with no declines recorded, as Grok 4 held the top spot at 94.00 points.
The WDCD v3.1 five-constraint scenario evaluation shows business rules scenarios scoring the lowest across the board, with Doubao-Pro at only 1.83/4, far below Grok-4's perfect 4/4. Safety compliance scenarios also saw an extreme low of 1.87/4, making these two scenarios the hardest-to-pass pressure zones in current compliance testing.
