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.

LOCAL ISN'T PRACTICAL

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.

LongCat 2.0 runs an always-on thinking mode. Reasoning (thinking) tokens are billed at the output rate ($15.00/M), so count them here to see the thinking portion of your bill.

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?

NO - NO INDIVIDUAL RIG RUNS IT

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.

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.
