Can I run LFM2.5 2.6B on GeForce RTX 3080 10GB?
Runs
Runs fully on your GeForce RTX 3080 10GB at BF16, 8K context, about 71–97 tok/s. Weights 5.03 GB plus 0.47 GB of KV cache — 5.85 GB of 9.03 GB usable. Up to 32K context still fits.

Assumptions
- Estimate from memory bandwidth, not a benchmark. Decode speed uses 55–75% of peak bandwidth.
- KV cache is FP16. Engine overhead assumes llama.cpp (0.3 GB + 1% of the weights). Ollama is closer to 0.9 GB + 3%, LM Studio closer to 1 GB + 3%.
- BF16 size is the real GGUF file size from Hugging Face.
- 0.5 GB is reserved because this GPU also drives a display, then 5% of the rest is left free.
- Speed is quoted at 8K context, not at the maximum context that still fits.
