Astra vs LongCat-2.0
Values come from Astra and LongCat-2.0, where each is cited to its source. This page states no benchmark result and ranks neither model — it puts two published specifications next to each other. Where a lab has not published a figure, the row says so rather than guessing.

What actually differs
- Context window
- Astra takes 1.1M against 1M — modestly more room in a single request.
- Input price
- LongCat-2.0 at $0.3/M against $10/M — 33.3× cheaper to feed. Standard rates: one of these labs also quotes a lower cached-input tier, which applies only when a prefix is reused — see the full spec below.
- Output price
- LongCat-2.0 at $1.2/M against $50/M — 41.7× cheaper to generate. Output dominates the bill on most agentic workloads, where the model writes far more than it reads.
- Weights
- LongCat-2.0 publishes weights (MIT (commercially permissive)); Astra is API-only. That decides self-hosting, air-gapped deployment and fine-tuning before any capability question does.
- Recency
- Astra shipped 65 days after LongCat-2.0 (2026-09-03 vs 2026-06-30).
