The Tool Isn’t the Product
New tools can transform how fast you build and innovate. The real challenge is making sure they work for you today without controlling your product tomorrow. Learn how to take full advantage while keeping the freedom to adapt.
GPT‑5: A Step Forward, Not a Breakthrough
OpenAI’s release of GPT‑5 brings improvements in context length, multimodal inputs, memory, and personalization, but without the dramatic leap some expected. This article takes a grounded look at what actually changed, what is genuinely useful, and where the launch overpromises. From quiet interface upgrades to overstated benchmarks and one now-infamous chart, we examine GPT‑5 for what it is: a solid step forward rather than a breakthrough.
Anatomy of a Discovery Phase
A strong discovery phase is the backbone of successful custom software development. At Rebl, we approach it as a focused process to uncover unknowns, validate assumptions, and align with clients early. This article outlines our step-by-step method, from defining goals to technical deep dives, and shows how early clarity leads to better decisions, smoother execution, and stronger results.
Rethinking MVPs: What Still Works, What Doesn’t, and What Changed
The concept of the MVP has drifted from its original purpose. Once a tool to reduce risk and test assumptions with minimal effort, it’s now often misused as just another step in the roadmap. The article challenges common misconceptions, explains how MVPs have evolved, and outlines what still makes them effective in 2025. With tools making it easy to build fast, the real challenge is clarity: knowing what you're validating, why it matters, and who it's for. Without that focus, an MVP is just noise.
Grok 4: AI's Smartest Model or Just Hype?
Grok 4, xAI’s latest frontier model, arrives with bold claims and benchmark wins—but does it deliver beyond the hype? This article unpacks its performance, architecture, pricing, and ethical concerns to give you a grounded look at what Grok 4 really offers. From multi-agent reasoning to its $300/month price tag, we cut through the noise to assess whether it’s a breakthrough tool—or just another iteration in the AI arms race.
