12 GB VRAM + 32 GB RAM · 672 GB/s memory bandwidth · LFM2.5 24B-A2B has 24B parameters (2B active per token).

Short answer

It loads, but it's borderline even for chat.

Best quantization for chat: Q4_K_M (14 GB of weights) on Ollama. Generation: 60–100 tok/s, leaving about 0.0 GB free for your other apps.

How it rates for each workload

Same model and machine, different jobs. Agents and long documents send far bigger prompts than chat, so they need much more speed and memory.
