what do people think about Opus 4.5 for coding so far? what are the behavioral problems or limitations you still want to see improved? we're hungry for feedback 🙏

Context Arena Update: Added kimi-linear-48b-a3b-instruct [11-08] and kimi-k2 (Thinking) [11-06] to the MRCR leaderboards. The Linear 48b results are fascinating! It actually outperforms the new Gemini 3.0 Pro Thinking on 4-needle and 8-needle tasks at higher context lengths (512k+). I've added it to 2needle, 4needle, and 8needle. kimi-k2 (Thinking) lands lower on the leaderboards (Rank #22 for 2-needle AUC @ 128k), with a hard context ceiling around 262k. I did not run it for 2needle and 4needle. All results at: contextarena.ai The performance curve for the Linear model is distinct: while it underperforms Gemini 3 significantly at shorter contexts (<=256k) on the difficult 8-needle test, its degradation slope is much flatter. Gemini starts higher and drops fast; Kimi starts lower but holds steady, overtaking Gemini at the higher end. However, note that kimi-linear-48b has noticeable performance drops past 128k on the easier 2 & 4 needle tests. Additionally, due to lower token efficiency compared to Gemini/GPT, only ~60% of the 1M token tests successfully ran (hitting limits/OOM). So some caution with the results at the 1M level. kimi-linear-48b results: 2-Needle Performance (@ 128k / @ 1M): - AUC: 96.5% (vs Gem 3: 99.5%) / 81.7% (vs Gem 3: 85.5%) - Pointwise: 96.0% (vs Gem 3: 99.0%) / 77.0% (vs Gem 3: 72.2%) 4-Needle Performance (@ 128k / @ 1M): - AUC: 85.5% (vs 85.8%) / 62.7% (#1, beating Gem 3: 57.3%) - Pointwise: 83.7% (vs 80.8%) / 51.5% (#1, beating Gem 3: 34.3%) 8-Needle Performance (@ 128k / @ 1M): - AUC: 54.9% (vs 73.0%) / 43.8% (#1, beating Gem 3: 39.0%) - Pointwise: 49.0% (vs 54.2%) / 35.3% (#1, beating Gem 3: 24.5%) A very different architectural approach yielding impressive stability at scale. Because of its current price point, it is very competitive for long context (MRCR). Enjoy. @Kimi_Moonshot @GoogleDeepMind @googleaidevs @OpenAI @OpenAIDevs
