Claude Opus 4.7 Drops—And Microsoft Breaks Ranks with OpenAI to Integrate It Day One
Last month, a GitHub post went viral for all the wrong reasons.
A senior AMD engineer published a post with a blunt title: “Claude Has Degenerated to the Point Where It Can’t Be Trusted for Complex Engineering Tasks.”
Not a casual complaint—actual evidence, logs, and benchmark comparisons.
Hundreds of developers piled in: “Same here,” “4.6 has become so conservative,” “Multi-step tasks give up halfway and return answers that look right but don’t actually work.”
I was using Claude 4.6 on a project at the time. Honestly, I felt it too. The model had gotten… cautious. Like it was afraid to make decisions, defaulting to safe, “correct-looking” answers instead of the bold, predictive solutions I’d gotten used to from earlier versions. Where did the old Claude go?
Turns out, I wasn’t imagining things.
Claude 4.6 wore the “model degradation” crown for roughly a month.
Then Anthropic Responded—Fast
On April 16th, Anthropic dropped Opus 4.7.
Not a routine update. This felt like emergency triage. The changelog emphasized software engineering capabilities and visual understanding improvements, but the community’s real question: Did they fix the “getting dumber” problem?
Then Microsoft added fuel to the fire.
On April 17th, a surprising headline appeared: Microsoft integrated Claude Opus 4.7 into GitHub Copilot and eight other development environments on day one.
Note that “day one.”
Microsoft and OpenAI have a deeply exclusive partnership—everyone knows this. But this time, no waiting period, no “exclusive window.” Claude Opus 4.7 dropped, and GitHub Copilot supported it immediately.
What does this mean?
My take: This isn’t Microsoft ditching OpenAI, but it does signal that Claude has become indispensable enough in coding scenarios that Microsoft had to set aside its historical exclusivity.
GitHub Copilot’s core use cases are code completion, generation, and explanation. Claude has always performed well here. But the real differentiator is what developers keep citing—Claude’s ability to handle complex engineering tasks: understanding large codebases, coordinating multi-file changes, debugging effectively.
That’s what made Microsoft blink.
The Community Is Still Divided
Post-4.7 release, the feedback split three ways. Some devs say “4.7 is noticeably better, complex tasks are more stable.” Others insist “Still not as good as 4.5, maybe even 4.6.” And a vocal group is complaining about the price—50% more expensive than 4.6, for arguably worse performance in some scenarios.
“Give us back 4.6” is trending on the ClaudeAI subreddit.
So where does this leave us?
Anthropic spent a month getting roasted and apparently shipped fixes—though at a higher price point. Microsoft breaking its exclusivity habit tells us one thing clearly: Claude’s value in programming scenarios has been market-validated. Whether users actually accept the new pricing is another question entirely.
I’m still on 4.6 myself, waiting for more comprehensive benchmarks before upgrading.
What about you? Using Claude or another AI coding tool and noticed capability swings over time? Is it the model degrading, or something else—compute allocation, commercial decisions?
Reflection Question
Have you noticed AI coding tools behaving inconsistently at different periods? Do you think it’s the model itself, or something else—compute allocation, commercial decisions?
