Welcome to the Modeldex blog
What we're building, why AI-model information is still hard to find, and what you can expect from this blog.
By Modeldex team
Modeldex is the place we always wanted to exist when choosing between AI models: a single, continuously-updated registry of every meaningful model, with the pricing, benchmarks, capabilities, and news in one place.
This blog is where we'll publish the longer-form work that doesn't fit in a spec sheet.
What you can expect
Deep dives into new model releases. When a new flagship drops, we'll pull together the benchmark numbers, independent evaluations, and real pricing into one post so you don't have to assemble it yourself.
Comparisons with teeth. Not "GPT vs Claude, here are the marketing bullets," but side-by-side evaluations that call out where each model actually breaks down.
Editorial on the ecosystem. Pricing wars, context-window inflation, provider consolidation, the MCP/tool ecosystem — the macro stuff that shapes what you'll be shipping six months from now.
How we pick our data sources. Transparency about where benchmark numbers, pricing snapshots, and capability data come from — and how fresh each one is.
Who we're writing for
Engineers and researchers who ship AI-powered software. CTOs trying to pick a default model. Solo builders who want an honest answer to "what should I use for this?"
If that's you: follow along, push back when we get something wrong, and tell us what you wish existed here.
