So last week, Anthropic released Claude Opus 4.6, and OpenAI fired back with GPT-5.3 Codex. Both were literally scheduled for the same time (10 AM PST), but Anthropic moved theirs up 15 minutes early to go first. Petty? Yes. Do I love it? Also yes. The whole week was chaos, honestly. OpenAI poached an Anthropic safety researcher on Tuesday. Then Anthropic dropped Super Bowl ads mocking OpenAI for putting ads in ChatGPT. Sam Altman responded with a full rant on X, calling Anthropic “authoritarian.” Then both drop their best models within an hour of each other on Thursday. Felt like watching two kids trying to one-up each other at recess. The interesting part is that the models are going in totally different directions. Opus 4.6 is the deep thinker: 1M-token context, better at legal and financial reasoning, catches edge cases other models miss. But it’s slower. GPT-5.3 Codex is the speed demon, 25% faster, fewer tokens, crushed coding benchmarks. Oh, and OpenAI says the model helped debug itself during training. That’s either really cool or really unsettling, depending on how you think about it. The number that stuck with me: OpenAI’s enterprise market share dropped from 62% to 53% in two years, while Anthropic grew from 14% to 18%. The gap is closing. So, where do you land, Team Claude or Team Codex? Or are you just using both and letting them fight it out? submitted by /u/Deep_Ladder_4679
