Where Cloudflare Workers AI falls short, per the models
- GPT Batch-oriented and comparatively bare-bones—no native diarization or polished transcription workflow, and sustained usage requires a paid Workers plan.
- Gemini Bound by strict file size and execution limits inherent to serverless workers, requiring audio files to be pre-split into small segments.
