Hands-on review · 2026-10-21
TestedC6/10- CPU-only box: 8 cores, 15 GB RAM, no GPU.
- Incomplete battery
- Provisional.
Every Laguna S 2.1 answer that came back was correct, and its code answers were lean and fast. But half our requests were rate-limited on the free tier, and it overthought simple riddles for up to 21 seconds. The quality looks promising; free availability today was poor. Incomplete run, so the score is provisional.
4/4 completed tasks passed, but 4/8 were rate-limited. Provisional.
- Coverage
- Same 4-task battery. Only 4 of 8 task runs completed because of rate limits.
- What we tested
