August 5, 2025Claude Opus 4.5 Thinking 16K scores 63.8 on the Extended NYT Connections benchmark (Opus 4.1 Thinking 16K: 58.8, Sonnet 4.5 Thinking: 48.2).
It seems like these labs are each discovering things that are allowing them to improve quickly. I wonder though how much are they working together? Gemini looks to be better in ways that Claude isn't, and Claude better in was that Gemini isn't. Same for Grok, and OpenAI. I think GPT 5.1 is really really great and I had a "woah" moment as you can almost tell it is having multiple layers of thinking similar to a human mind. And Grok is really great at how it presents information and talks to you, though it is the model I trust the least. It just feels like we have a long way to go. Like we already have many models who are really great in certain areas, and that even if we don't improve, but just combine and align what we currently have, then we are already in deep waters that will lead to massive disruptions More on reddit.com

1 month agoAnthropic has released Claude Opus 4.5. SOTA coding model, now at $5/$25 per million tokens.
The biggest news for me is: For Max and Team Premium users, we’ve increased overall usage limits, meaning you’ll have roughly the same number of Opus tokens as you previously had with Sonnet. If Opus 4.5 doesn't degrade after a while, this can be a game changer for me, as I won't need to be as hands on. More on reddit.com

GPT-5.2 Codex vs Gemini 3 Pro vs Claude Opus 4.5
7 hours ago - Budget: $300+/month per developer Recommendation: Gemini 3 Pro + GPT-5.2 Codex + selective Opus 4.5 Why: Maximum capability coverage, ROI justifies cost · The December 2025 AI model landscape has produced clear winners for different use cases. Gemini 3 Pro emerged as the surprise leader for frontend development, combining superior visual quality with the lowest costs. GPT-5.2 Codex proved itself as the most reliable all-rounder, delivering consistent results across diverse coding challenges. Claude Opus 4.5's poor performance in these tests is a stark reminder: high benchmark scores don't always translate to real-world success, especially in UI-heavy work.

I am very happy to be positive about this, it does feel as though they may have listened to a lot of the complaints about the model. HOWEVER: on loading CC, I see: To give you room to try out our new model, we've updated usage limits for Claude Code users Emphasis mine - And the pessimist in me says "this is literally just to build hype and will be reduced swiftly" So I wouldn't get too happy about the limits, but the API cost reduction could signify this change may be permanent? Either way, best to enjoy the model for now. Looks like Claude is back on top (for coding, Gemini is still SOTA for overall reasoning) EDIT: So it seems like Pro users don't get Opus still in Claude Code. So I am firmly back down on the hype train. What a bitch move
