This is the weirdest technology market that I’ve seen. Researchers are getting rewarded with VC money to try what remains a science experiment. That used to be a bad word and now that gets rewarded with billions of dollars in valuation.
I don't know if that's indicative of the market as a whole though. Zuck just seems really gutted they fell behind with Llama 4.
I've started breathing a little easier about the possibilty of AI taking all our software engineering jobs after using Anthropic's dev tools.
If the people making the models and tools that are supposed to take all our jobs can't even fix their own issues in a dependable and expedient manner, then we're probably going to be ok for a bit.
This isn't a slight against Anthropic, I love their products and use them extensively. It's more a recognition of the fact that the more difficult aspects of engineering are still quite difficult, and in a way LLMs just don't seem well suited for.
The specific issue you linked is related to the way Ink works, and the way terminals use ANSI escape codes to control rendering. When building a terminal app there is a tradeoff between (1) visual consistency between what is rendered in the viewport and scrollback, and (2) scrolling and flickering which are sometimes negligible and sometimes a really bad experience. We are actively working on rewriting our rendering code to pick a better point along this tradeoff curve, which will mean better rendering soon. In the meantime, a simple workaround that tends to help is to make the terminal taller.
Please keep the feedback coming!
CC is one of the best and most innovative pieces of software of the last decade. Anthropic has so much money. No judgment, just curious, do you have someone who’s an expert on terminal rendering on the team? If not, why? If so, why choose a buggy / poorly designed TUI library — or why not fix it upstream?
Other terminal apps make different tradeoffs: for example Vim virtualizes scrolling, which has tradeoffs like the scroll physics feeling non-native and lines getting fully clipped. Other apps do what Claude Code does but don’t re-render scrollback, which avoids flickering but means the UI is often garbled if you scroll up.
Tech debt isn't something that even experienced large teams are immune to. I'm not a huge TypeScript fan, so seeing their choice to run their app on Node to me felt like a trade-off between development speed with the experience that the team had and at the expense of long-term growth and performance. I regularly experience pretty intense flickering and rendering issues and high CPU usage and even crashes but that doesn't stop me from finding the product incredibly useful.
Developing good software especially in a format that is relatively revolutionary takes time to get right and I'm sure whatever efforts they have internally to push forward a refactor will be worth it. But, just like in any software development, refactors are prone to timeline slips and scope creep. A company having tons of money doesn't change the nature of problem-solving in software development.
It gets lost on people in techcentric fields because Claude's at the forefront of things we care about, but Anthropic is basically unknown among the wider populace.
Last I'd looked a few months ago, Anthropic's brand awareness was in the middle single digits; OpenAI/ChatGPT was somewhere around 80% for comparison. MS/Copilot and Gemini were somewhere between the two but closer to Open AI than Anthropic.
tl;dr - Anthropic has a lot more to gain from awareness campaigns than the other major model providers do.

As a frequent traveller I'm not sure if some of those features are gated by region, because some people said they can do some of those things, but if that is true, then that still makes the UX worse than the competitors.
However, I speak with a small subset of our most experienced engineers and they all love Claude Sonnet 4.5. Who knows if this lead will last.
I don't see what the basis for this is that wouldn't be equally true for OpenAI.
Anthropic's edge is that they very arguably have some of the best technology available right now, despite operating at a fraction of the scale of their direct competitors. They have to start building mind and marketshare if they're going to hold that position, though, which is the point of advertising.
This is the reason they haven't bothered to provide an image generator yet - because Chat users are not their focus.
Of course OpenAI has tons of money and can branch off in all kind of directions (image, video, n8n clone, now RAG as a service).
In the end I think they will all be good enough and both Anthropic and OpenAI lead will evaporate.
Google will be left to win because they already have all the customers with the GSuite and OpenAI will be incorporated at massive loss in Microsoft, which is already selling to all the Azure customers.
