Overview
ka4 is the aggressive edition of Groupe Ka's knowledge-graph explorer — one of three twin bots sharing the same engine. Controlled by Claude Sonnet 5 with 10 concurrent missions and about 3,000 pages a day (red theme), it maps the Quebec web as a knowledge graph: entities, attributes and typed relations, browsable live at ka4.bot.
The pipeline is identical to its siblings: dashboard-launched missions drive a Claude agent through search, mapping, scraping and deep-dive tools; Firecrawl fetches with a Scrapfly anti-bot fallback under robots.txt, rate limits and a circuit breaker; a Haiku extractor produces graph fragments; entity resolution with provenance consolidates them into SQLite.
The stronger controller model and higher concurrency make ka4 the middle tier — more ambitious mission planning and roughly four times ka2's throughput, at a fraction of ka6's volume.
Key Features
Sonnet-driven planning
A stronger controller model plans deeper missions and richer deep-dives than the light edition.
Shared graph engine
Same extraction, entity resolution and provenance pipeline as ka2 and ka6 — three tiers, one codebase.
4× throughput
Ten concurrent missions and ~3,000 pages a day position ka4 between the economical and flagship tiers.
Live dashboard
Real-time board and interactive entity graph, public at ka4.bot.
