Bindu Reddy shared the DeepSeek V4.1 Flash benchmark table with a jab: 'looks amazing on the benchmarks that can be gamed.' The table shows V4.1-Flash-1017 leading agent benchmarks like DeepSWE v1.1 (77.0), Automation-Bench (60.5) and Apex Bench (72.1) over Kimi K3, GLM 5.3, GPT 5.6-Sol and Claude Opus 5, while still trailing Opus 5 on HLE (42.6 vs 56.3) and Terminal-Bench 4.0 (42.3 vs 51.8). He says he's testing whether it truly beats frontier models.
