Payment evidence: current spend or explicit intent
ProblemClaude API coding costs run high in practice: one documented case shows $1000 spent to code a single application. Switching to GLM 5.3 produced the same coding result for $10, but developers lack trusted, side-by-side information on equivalent lower-cost LLM alternatives and migration steps.

Scoring summary

Evidence confidence = strength × evidence volume × source diversity × payment × competition × trend × 10. Counts use independent content items; only first-hand pain, current spend, explicit willingness to pay and concrete feature requests affect the score. Repeated posts by one author are discounted. Scoring and status changes follow deterministic rules.

“Payment-backed” means first-hand payment evidence exists in the record. It does not mean the business is worth building. “Fading” is a recency tag shown alongside any evidence level, not a lower level. Read the full methodology.
