AI tools that run on 24 GB VRAM
Twenty-four gigabytes is a flexible consumer-workstation tier. It supports upstream-documented Flux LoRA configurations and gives heavy image or video graphs more room, but it does not guarantee that every large model, precision, context, or frame sequence stays fully on the GPU.
Capabilities
✓ WHAT YOU CAN RUN
- HunyuanVideo (GGUF Q4_K_M / FP8)
- Wan 2.2 14B at FP8
- Flux LoRA training in Kohya / OneTrainer
- Larger quantized LLMs when weights, KV cache, and runtime overhead fit together
- Large-batch SDXL & Flux production runs
✕ WHAT STAYS OUT OF REACH
- Wan 2.2 14B at BF16 (needs 48 GB)
- Full fine-tuning of 13B+ models without LoRA
- High-concurrency serving without budgeting separately for each session’s KV cache
VRAM tier ≠ universal guarantee
These are planning envelopes. Model variant, precision, resolution, frame count, context, cache, runtime, and offload can move the same workload across tiers. The guide shows how to validate a real ComfyUI graph before buying hardware.
