What actually differs
- Context window
- Identical — both accept 1M tokens, so context length is not a reason to pick either.
- Weights
- Beam 1.0 publishes weights (Apache 2.0); Kimi K2.8 Preview is API-only. That decides self-hosting, air-gapped deployment and fine-tuning before any capability question does.
- Recency
- Beam 1.0 shipped 35 days after Kimi K2.8 Preview (2026-10-16 vs 2026-09-11).
