LongCat 2.0 cost & VRAM calculator
What does LongCat 2.0 cost to run for your workload, and can you run it on your own hardware? Set your workload below - we compute per-provider API cost live and tell you honestly whether local hardware can run it.
This is where owning stops making sense
LongCat 2.0 is a 1600-billion-parameter model. No rig an individual can buy runs it - so unlike a workstation GPU model, there's no break-even to compute. The honest answer for nearly everyone is the per-provider API cost below.
1.6T total params, MoE with ~48B active per token. 1M native context via LongCat Sparse Attention (LSA); zero-compute experts dynamically route 33-56B per token. Open weights under MIT license (also the model behind OpenRouter’s Owl Alpha). FP8 and INT8 quantized variants published alongside the base model.
Your workload
API cost for your workload
| Provider | Rate ($/1M) | Monthly cost |
|---|---|---|
| AtlasCloud | $0.30 in · $1.20 out · $0.01 cache | $0.01 cheapest |
Monthly cost is an estimate from list prices and your workload - verify against the provider before committing. Cached fraction applies the cache rate to that share of input.
Can you run it locally?
LongCat 2.0 has no published quantization that fits a rig one person can buy, so there's no local-hardware recommendation and no break-even to compute. The honest answer is the per-provider API cost above.
