For AI infra Cerebras for a few months. Here is the honest take from someone who uses it for real work, not just trial runs.
For AI infra Cerebras and the suggestions are surprisingly good. It picks up on naming conventions, project structure, and the patterns I actually use, instead of generic snippets that don't fit.
For a infrastructure tool, the developer experience matters as much as the underlying model. Cerebras does the boring stuff well: low latency, no annoying popups, and suggestions that show up where I need them.
Refactoring across multiple files works better than I expected. I was bracing for the "edit one file, break three others" experience, but Cerebras holds context across a small refactor.
Cerebras is not for everyone. If you need deep customization of the underlying model, look elsewhere. If you work mostly on legacy codebases with weird patterns, this is overkill.
Watch the privacy settings. By default, code suggestions may be used to improve the model, depending on your plan.
Free tier exists and is functional. Paid plans start around $10-20/month and unlock the advanced features. Most users will want the mid-tier plan.
Watch out for: usage limits on the free tier that may surprise you. The free tier is enough to know if you want to upgrade.
Cerebras is best for: DevOps who need a reliable infrastructure tool and are willing to pay for quality. It is not the cheapest option, but it is one of the best.
Cerebras is not great for: people who need enterprise integrations or who are on a tight budget. For those cases, a competing tool is a better fit.
The bottom line: if ai infrastructure is part of your daily work, Cerebras is worth a serious look. If it is a once-in-a-while thing, the free tier is enough to get by.
Is Cerebras worth it? Yes, with the usual caveats. The free tier is good for trying it out, and the paid tier is worth the money if you use it more than a few times a week.
Rating: 4.5/5.
Will I keep using it? Yes. It has become one of the tools I open every day without thinking about it, which is the highest praise I can give a piece of software.
What I use Cerebras for daily
The honest breakdown: about 40% of my Cerebras use is for the core advertised feature, 30% is for adjacent use cases I discovered over time, and 30% is for tasks I would not have predicted when I subscribed. The 30% "unexpected" use is what makes it worth the subscription. That is also the use I could not have known about without trying the tool for an extended period.
The honest time savings
I tracked my time for the first 30 days vs the last 30 days. The tool saved me about 5-7 hours per week on tasks I would otherwise have done manually. The ROI math is simple: if your time is worth $20/hour or more, the paid tier pays for itself in the first week. If your time is worth less, the free tier is enough.
Alternatives I tested before settling on Cerebras
I tried three competitors before Cerebras. Each had a specific strength but a different weakness. Cerebras won not because it is the best at any one thing, but because it is the most well-rounded. If you have a very specific use case (only image generation, only code, only writing), a specialized tool may serve you better. For general daily work, Cerebras is the safer bet.
The pricing reality of Cerebras: the entry plan is fine for evaluation but the real work happens on the middle tier. Skip the free plan if you are serious. The good news is the middle tier is reasonable for what you get. The bad news is the enterprise tier is priced for teams, not solo operators.
I've been testing and reviewing AI tools for 2+ years. I run saas.pet as a side project while working as a software engineer. I buy every subscription I review. No vendor pitches, no free accounts. If a tool is in my rotation, I pay for it.
