What a week for AI model releases. We’re at the end of the week and we’ve already seen 10+ new models drop, including some major releases. A quick recap: > Claude Opus 5.5 > GPT-6 Sol > GPT-6 Luna > Grok 4.7 > Step 5 Preview > GLM-5.3 Prime > Agora-2 > MiMo-V2.6 Pro For me, Claude Opus 5.5 was easily the best release of the week. And next week could be another banger with OpenAI DevDay fast approaching. One of the busiest stretches for AI releases we’ve had in a while.
