Can I run LFM2.5 2.6B on Intel Arc B580?

Runs great

Runs great fully on your Intel Arc B580 at BF16, 8K context, about 42–58 tok/s. Weights 5.03 GB plus 0.47 GB of KV cache — 5.85 GB of 10.9 GB usable. Up to 64K context still fits.

Run commands

ollama run lfm2.5

lms get LiquidAI/LFM2.5-2.6B-GGUF
# Then load quant BF16

Assumptions

• Estimate, not a benchmark. Decode speed uses a memory-bandwidth model at 55–75% of peak.
• 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.
