Probé TODOS los modelos de GPT-5.6 (SOL, TERRA, LUNA)

Today I'm testing GPT 5.6 in its three versions: Sol, Terra, and Luna. The idea is to see which program performs best, which responds fastest, and, above all, which offers the best value for money. I'm also comparing them to Opus 4.8 and Fable 5 in two real-world tests: creating a website and building a music player. No need to rely solely on benchmarks; here we see real times, results, and costs. At the end, I'll tell you which one I would choose based on your intended use and budget. ⏱️ CHAPTERS 0:00 GPT 5.6: Sol, Terra, and Luna 2:25 Comparison with Fable 5 and Opus 4.8 5:58 Real-world test: creating a website 11:20 Second test: music player 15:49 Independent benchmarks and costs 18:24 The best value model 21:29 Which model should you use? 25:10 Final conclusions
