Ling-3.0-flash GGUF size and VRAM requirements
bartowski/Ling-3.0-flash-GGUF is a very large language model with 127.49 billion parameters, built on the bailingmoe3 architecture. It is released under the mit license and has been downloaded 15,488 times.
Ling-3.0-flash-GGUF is a Mixture-of-Experts model with 512 experts, of which 8 are active on each token. Routing only 8 of 512 experts makes it noticeably faster than a dense model of the same size — but every expert still has to be held in memory, so the numbers below are set by the full parameter count, not the active one. It is built from 42 transformer layers, a hidden size of 2,560, 32 attention heads. Ling-3.0-flash-GGUF uses Multi-head Latent Attention, caching a single compressed latent per layer instead of full keys and values. That keeps the KV cache small even at long context — the memory figures on this page already reflect it.
To run bartowski/Ling-3.0-flash-GGUF locally at a 4,096-token context, its quantized versions need between 26.66 GB (IQ1_S, lowest quality) and 238.56 GB (BF16, highest quality) of memory, weights plus KV cache and a system margin included. Context length drives that memory directly: at 4,096 tokens the KV cache for Ling-3.0-flash-GGUF is about 0.18 GB, rising to roughly 11.81 GB at its full 262,144-token context. Shorter prompts free up memory for a higher-quality quantization.
Available GGUF quantizations for bartowski/Ling-3.0-flash-GGUF include IQ1_S, IQ1_M, IQ2_XXS, IQ2_XS, IQ2_S, IQ2_M, Q2_K, Q2_K_L, IQ3_XXS, Q3_K_S, IQ3_XS, Q3_K_M, Q3_K_L, IQ3_M, Q3_K_XL, IQ4_XS, IQ4_NL, Q4_0, Q4_K_S, Q4_K_M, Q4_K_L, Q4_1, Q5_K_S, Q5_K_M, Q5_K_L, Q6_K, Q8_0, BF16. The model supports a native context length of up to 262,144 tokens; a longer context grows the KV cache and the memory needed.

Frequently asked questions
What kind of model is bartowski/Ling-3.0-flash-GGUF?
bartowski/Ling-3.0-flash-GGUF is a language model with 127.49 billion parameters, based on the bailingmoe3 architecture. It is released under the mit license and distributed as GGUF files for local inference.
Is bartowski/Ling-3.0-flash-GGUF a Mixture-of-Experts (MoE) model?
Yes. bartowski/Ling-3.0-flash-GGUF is a Mixture-of-Experts model with 512 experts, of which 8 are activated per token. That makes it faster than a dense model of the same size, but all 512 experts must be loaded into memory, so the VRAM/RAM it needs is driven by the total parameter count, not the active one.
How does bartowski/Ling-3.0-flash-GGUF handle long context?
bartowski/Ling-3.0-flash-GGUF uses Multi-head Latent Attention, which caches one compressed latent per layer instead of full keys and values. Its KV cache therefore grows much more slowly than a standard model of the same size, so long contexts add relatively little memory.
How much VRAM do you need to run bartowski/Ling-3.0-flash-GGUF?
You need about 29.45 GB of VRAM to run bartowski/Ling-3.0-flash-GGUF entirely on the GPU using the IQ1_M quantization (at a 4,096-token context). Smaller quantizations lower the requirement at the cost of quality.
Can I run bartowski/Ling-3.0-flash-GGUF on an 8 GB GPU?
No. bartowski/Ling-3.0-flash-GGUF does not fit on an 8 GB GPU, even with the smallest quantization and system RAM offloading.
Can I run bartowski/Ling-3.0-flash-GGUF on a 16 GB GPU?
Partially. bartowski/Ling-3.0-flash-GGUF only fits on a 16 GB GPU by offloading part of it to system RAM (with Q2_K_L), which runs but is slower.
Can I run bartowski/Ling-3.0-flash-GGUF on a 24 GB GPU?
Partially. bartowski/Ling-3.0-flash-GGUF only fits on a 24 GB GPU by offloading part of it to system RAM (with Q4_K_S), which runs but is slower.
What context length does bartowski/Ling-3.0-flash-GGUF support?
bartowski/Ling-3.0-flash-GGUF supports a native context length of up to 262,144 tokens. A longer context grows the KV cache, so it increases the memory needed to run the model.
What is the best quantization for bartowski/Ling-3.0-flash-GGUF?
For bartowski/Ling-3.0-flash-GGUF, a strong default is Q4_K_M, which needs about 73.45 GB and keeps most of the quality while roughly halving the memory versus 8-bit. With VRAM to spare, Q5_K_M or Q6_K add a little more quality; if you are tight on memory, a smaller quantization still runs. Pick the highest quantization that fits your VRAM.
