DeepSeek V4.1 Flash just dropped, and it's now the MOST EXPENSIVE small model on the BridgeBench lava lamp test.
DeepSeek V4.1 Flash: $0.04, 4m 3s
Claude Haiku 5.5: $0.03, 4m 34s
GPT 6 Luna: under $0.01, 42.8s
Luna built the best lamp of the three. Cheapest, fastest and best.
Also, DeepSeek's launch chart compares against Opus 5 and GPT 5.6 Sol. Two generations old.
GPT 6 Luna is still the best small model.
