Notes
MoE vision-language model with 16B total and about 3B active parameters; it needs trust_remote_code and was developed against transformers 4.48.2. vLLM support needed a branch from an unmerged pull request (#16387) when the card was written.
Questions
- How much VRAM does Kimi VL A3B need?
- At mlx-5bit, Kimi VL A3B needs about 12 GB of memory at 8k context and 16 GB at 128k, counting the weights, the KV cache and runtime buffers.
- What is the best GPU for running Kimi VL A3B locally?
- The cheapest hardware in Canada that runs Kimi VL A3B fully in memory at 128k context is the Intel Arc Pro B60, $1,060 at Amazon, at about 17 tok/s (estimated). The best value is the NVIDIA RTX PRO 6000 Blackwell (about 91 tok/s for $3,133). The fastest we price is the NVIDIA RTX PRO 6000 Blackwell, at about 91 tok/s.
- Can I run Kimi VL A3B on a 16 GB GPU?
- Only partly: at 128k context it does not fit in 16 GB, so part of it runs from system RAM and it slows to about 19 tok/s on the Intel Arc A770 16GB (estimated).
- Can I run Kimi VL A3B on a 24 GB GPU?
- Yes: at mlx-8bit it fits fully in 24 GB at 128k context. On the NVIDIA GeForce RTX 3090 Ti it runs at about 51 tok/s (estimated).
- What licence is Kimi VL A3B released under?
- MIT, which allows commercial use.
