Signal in AI news is any update that has a plausible, concrete impact on what you build, ship, or decide in the next 30–90 days. Launches, breaking API changes, and repeated capability patterns are signal.

The 5 noise types

1. Duplicate coverage

The same announcement covered by 10 outlets within 24 hours. You only need one—ideally the primary source.

2. Hype without substance

"AI is going to transform X industry" with no concrete product, model, or code artifact. High word count, low information density.

3. Outdated information presented as new

A benchmark or capability comparison that's 3–6 months old, recirculated as if it's current.

4. Speculation presented as fact

"Company X is rumored to be working on Y." Useful for context, not for decisions.

5. Irrelevant domain

Real signals in domains completely outside your stack, users, or roadmap. Even true, important, well-sourced news can be noise for you.

The 3-question filter

When you encounter an AI news item, ask:

Is there a primary source? (If not, it's likely noise type 1–4.)
Does it touch my stack, users, or roadmap? (If not, it's noise type 5 for me.)
Is it distinct from what I already know? (If not, skip the duplicate.)

Two or more "no" answers: skip it.

Summary

Signal = concrete impact on what you build in 30–90 days. Five noise types: duplicates, hype, outdated info, speculation, irrelevant domain. Apply the 3-question filter: primary source? Touches your work? Distinct information? Two "no" answers = skip.

FAQ

What about opinion pieces? Occasionally useful for context and pattern-spotting. Not signal unless they cite a primary source with a concrete artifact.
