August 7, 2025 - Scaling With Context – GPT-5 performed better in large-context scenarios, especially when changes spanned multiple files and required understanding project-wide constraints.

October 7, 2025 - After a month of the hue and cry from all the die-hard Claudians for lobotomizing Sonnet 4, Anthropic has released Claude 4.5 Sonnet, and, according to all Anthropic employees on Twitter, it's the best model for coding yet. It improves on the shortcomings of Claude 4 (personality) while retaining its best qualities (tool calling accuracy).

r/ClaudeAI on Reddit: When's Claude 5 dropping? Let's speculate
July 28, 2025 -
So we got Claude 4 (Opus & Sonnet) back in May, and it's been really good for me, especially for coding. But just like every person on this subreddit, I too am sleepwalking into the singularity, constantly refreshing anthropic news feed, praying for a new model or update.
Looking at Anthropic's release pattern: Claude 3 family launched March 2024, Claude 3.5 Sonnet dropped July 2024, Claude 3.7 Sonnet came Feb 2025, Claude 4 arrived May 2025 - what makes me hopeful is that the time between 3.7 and 4 was really quite short.
Now we are also in the early stages of recursive learning, where AI is already helping develop the next generation of AI https://www.anthropic.com/news/how-anthropic-teams-use-claude-code and based on recent results (math and coding competition) from openAI and their release of agent, this recursive learning cycle seems to be finally really picking up steam, and approaching that scary tipping point.
With the crazy competition right now - GPT-5 (in a few weeks), Gemini 2.5 Pro (with a decent CLI), and now Grok 4 - I'm wondering if Anthropic might accelerate their timeline. Dario predicted we could see 90% of coding automated within 6 months (from March), which suggests they're cooking something big.
My prediction: Claude 5 in Q1 2026, probably around Feb/March. But honestly, with how fast things are moving, it could be sooner, and I think an updated Claude 4 model is almost guaranteed sometime this fall.
What do you all think? Any patterns you've noticed or rumors you've heard? Also curious how you think it'll stack up against whatever Xai, OpenAI and Google release next. Claude 4's been dominating vibe-coding, but will they maintain that lead?

Is there any point to speculation? Some people have insisted that Claude 4 Sonnet is dumber than 3.7 Sonnet. I personally can't tell for all intents and purposes unless new features are added. One example is adding web search when it previously wasn't available. The only thing I tend to notice is perhaps the training data cutoff isn't as stale, that's about it.

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
