What actually differs
- Context window
- Inkling takes 1M against 500K — 2× more room in a single request.
- Weights
- Inkling publishes weights (Apache 2.0 (open-weight)); Grok 4.6 is API-only. That decides self-hosting, air-gapped deployment and fine-tuning before any capability question does.
- Recency
- Grok 4.6 shipped 23 days after Inkling (2026-08-07 vs 2026-07-15).
