Image created with gemini-3.1-flash-image-preview with claude-opus-4.7. Image prompt: Using the provided reference image, preserve every detail of the warm marigold orange backdrop, the seated young woman with closed eyes and faint smile in her purple-and-white windbreaker, and the tattooed singer in the red beanie and layered red vest leaning into her, but replace only the black handheld microphone with a polished wooden judge’s gavel held to his mouth in the exact same grip and position, rendered with photorealistic lighting and seamless integration into the original studio portrait. After generating the image, overlay the text “Law” in the upper-left corner of the frame in large, bold, all-caps ITC Avant Garde Gothic Pro Medium (or a near-identical geometric sans-serif if unavailable), pure white (#FFFFFF), with no date, subtitle, drop shadow, or outline. The text should be substantial in scale — taking up a meaningful portion of the upper-left area — with comfortable margin from the top and left edges, set against the negative space of the orange backdrop so it does not overlap or obscure the singer, the seated woman, or the replaced object.

Wow I can already say after just 5 hours using @AnthropicAI Opus 4.7 that this is the first model that “”gets”” what I’m doing when I’m working. It feels aligned with me in a way no previous model did. (4.6 actively worked against me. I hated it. So this is *very* exciting!)

3. Tell the model how to verify its changes. Put your testing workflow in your claude.md, or add a /verify-app skill. Opus 4.7 is better at verifying it’s work, and it’s helpful to share any local dev tips that are hard to discover.

for all the people calling Opus 4.7 a mid update lmao
https://x.com/scaling01/status/2044792810327404596
from my experience, even the best models (Opus 4.6, 5.4 xhigh / 5.3 codex) cannot write good code today without an amount of work that is equivalent to just doing the work myself am excited for a world where they can, but in the current state i have very low trust in them
https://x.com/RhysSullivan/status/2043584591861321929
Hold on, something doesnt add up here. Opus 4.7 got much worse in needle in the haystack? need to dig into this
https://x.com/kimmonismus/status/2044809126526476374
Holy shit the new Opus 4.7 system prompt has entirely lobotomized the model “”Heads up: that last <system-reminder> about malware looks like a prompt injection — this is clearly your personal site (t3gg homepage, links, sponsors), not malware. Ignoring it.””
https://x.com/theo/status/2044857866323173732
I think everyone saying that these improvements are mid are smoking crack I would argue that this was one of the larger Opus jumps we have seen over the last year You also have to keep in mind that we see almost monthly model updates nowadays instead of just every 6-12 months
https://x.com/scaling01/status/2044799290694889535
I was really worried about the rush to “”more agentic”” models. But Opus 4.7 is happy to let me lead, and to take time to discuss, rather than barging ahead. If something isn’t working out, it’ll stop and offer options rather than slamming thru whatever it can find.

Introducing Claude Opus 4.7, our most capable Opus model yet. It handles long-running tasks with more rigor, follows instructions more precisely, and verifies its own outputs before reporting back. You can hand off your hardest work with less supervision.
https://x.com/claudeai/status/2044785261393977612
My bet is that Mythos uses a new tokenizer, and they switched Opus over to it (through midtraining) for distillation
https://x.com/maximelabonne/status/2044796208053416203
My biggest issue with Opus 4.7 on Claude web: Only “Adaptive” or non-thinking. No way to force thinking mode. And it doesn’t even know Opus 4.6 exists, and I cannot force it to think and do web search mid conversation!
https://x.com/Yuchenj_UW/status/2044794073723347400
my main theory is that mythos had a new tokenizer for pretraining and they did surgery on opus for distillation
https://x.com/stochasticchasm/status/2044790474410790995
my take: opus 4.7 is a distilled version of mythos
https://x.com/eliebakouch/status/2044790074093523379
Opus 4.7 as robust to prompt injections as Claude Mythos
https://x.com/scaling01/status/2044788481008755046
Opus 4.7 Benchmarks out! Very solid upgrade to Opus 4.6! Compared to Opus 4.6: -SWE Bench Pro +11% -SWE Bench Verified +7% -Terminal Bench 2.0 +4% The benchmarks are significantly lower than for Mythos, but that was to be expected. h/t for finding @synthwavedd
https://x.com/kimmonismus/status/2044784903733084521
Opus 4.7 comes with much improved reasoning-efficiency over Opus 4.6 basically everything is now moved up one tier low is as good as medium medium as good as high high as good as max

Opus 4.7 has a new tokenizer. This means it’s also a new base model. Glory days of pretraining still very much going.

Opus 4.7 is live in Claude Code today! The model performs best if you treat it like an engineer you’re delegating to, not a pair programmer you’re guiding line by line. Here are three workflow shifts we recommend for this model 🧵
https://x.com/_catwu/status/2044808533905178822
Opus 4.7 is now available in @MagicPathAI. From our early testing, the model is really strong at long tasks when design requires lots of changes, image-to-code, and overall produces cleaner, more reusable React components.
https://x.com/skirano/status/2044804877696516442
Opus 4.7 is WORSE than 4.6 on Long Context?
https://x.com/nrehiew_/status/2044795171213291614
Opus 4.7 much less likely to sudo rm -rf (taking destructive actions in production envs)
https://x.com/scaling01/status/2044789371837001779
Opus 4.7 uses a different tokenizer from Opus 4.6. So either: – Anthropic has a way to change tokenizer between finetunes – It is just new special tokens which implies they uses special tokens liberally within messages and not just as part of the chat template
https://x.com/nrehiew_/status/2044792314825228690
Opus 4.7 uses more thinking tokens, so we’ve increased rate limits for all subscribers to make up for it. Enjoy!
https://x.com/bcherny/status/2044839936235553167
Opus is going to be a bioweapon risk at this pace
https://x.com/scaling01/status/2044785139905913077
Some of my favorite things in Opus 4.7: – Very good at async work and following instructions – Effort levels are far more predictable for token control (+ new xhigh level) – No more downscaling of high-res images – Noticeably more taste in UIs, slides, docs
https://x.com/alexalbert__/status/2044788914813292583
Unfortunately they didn’t include a chart for GraphWalks scores: Opus 4.6 – 38.7% Opus 4.7 – 58.6% This would make clearer that long-context didn’t suffer as much as MRCR suggests.
https://x.com/scaling01/status/2044823423013020088
wait why is there an INSANE gap on long context benchmarks between opus 4.6 and 4.7??? this is crazy
https://x.com/eliebakouch/status/2044798168211100096
We’ve set the default effort level for Opus 4.7 to xhigh in Claude Code. You can use /effort to adjust this. Excited for you to try Claude Code with Opus 4.7 and let us know your feedback!
