The first widely read description of the Sonic classifier: three probabilities, thresholds, example scores, plus the fields grouped_webpages, safe_urls, fallback_items and debug_sonic_thread_id. Coined the terms Sonic and SonicBerry in the field.
Describes a state from summer 2025 that a year later has partly vanished. The classifier result is no longer readable, the reference fields still exist. Anyone searching today for sonic_classification_result finds nothing; for that, the article is the chronicle, not the description.
| Claim | Status | Evidence |
|---|---|---|
| sonic_classification_result with simple/complex/no_search probabilities steers the search decision | outdated | Field not in the conversation object since our first measurement day 2026-08-20; only a sonic thread remains in the stream (routing.sonic_thread_present). |
| SonicBerry as a meta-search with paid/unpaid variants (current_sonicberry_paid_oai) | unverifiable | Identifier not seen in our data. |
| Fields grouped_webpages, safe_urls, fallback_items | confirmed | grouped_webpages and safe_urls observed daily; fallback_items not. |
| 31% search invocation across 8,700 terms (Chris Long) | outdated | 69% in the standard mode in our data (26 German prompts, 2026-08-22); different prompt base. |
