Ling Flash 2.0
inclusionAI · Text generation · MoE 100B (A6B) · 131k context · Released 16 September 2025
Ling Flash 2.0 is a sparse mixture-of-experts with a 1/32 activation ratio, which is what the developer credits for its speed: only about 6 billion of its roughly 100 billion parameters compute on each token. It is text-only, with a 32k native context the developer says extends towards 128k with YaRN. For local use the catch is familiar for a model of this shape: the small active count makes it quick, but it is the full 100 billion parameters that have to sit in memory, which puts it on a 128GB unified-memory machine or a multi-GPU server rather than a consumer card.
Strengths
- Highly sparse, so fast for its total size
- Sparse: only about 6 billion of ~100 billion parameters compute per token
- A permissive licence with no revenue threshold or territory restriction
- A capable general model at the quick end of the large tier
Weaknesses
- Server-scale footprint: ~58GB at 4-bit and ~206GB at BF16, set by the total not the active count
- Text-only, with no image or audio input
- A 32k native context, shorter than several rivals before YaRN extension
- Benchmark claims await independent verification
Hardware requirements
| Quantisation | Approx. VRAM | Notes |
|---|---|---|
| Q4_K_M (approx) | ~58GB | Roughly 58GB at 4-bit, which needs a 128GB unified-memory machine or multiple GPUs. Driven by the 100B total, not the active count. Approximate. |
| Q8_0 (approx) | ~106GB | Roughly 106GB. Multi-GPU or server territory. Approximate |
| BF16 (as released) | ~206GB | Full precision, roughly 206GB. Server territory. Approximate |
What you'd need to run this
Roughly what a machine to run this would need, at up to three levels of quality. Memory is the deciding factor.
Minimum to run it
Q4_K_M (approx) · ~58GB needed
96GB of unified memory
AMD Ryzen AI Max+ 395 (Strix Halo)or an 80GB-class data-centre card, which is usually rented by the hour, NVIDIA A100 80GB .
Unified memory is shared with the model, so it is already counted above.
For good quality
Q8_0 (approx) · ~106GB needed
128GB of unified memory
Mac Studio M4 Maxor an 80GB-class data-centre card, which is usually rented by the hour, NVIDIA H200 .
Unified memory is shared with the model, so it is already counted above.
Best quality
BF16 (as released) · ~206GB needed
A multi-GPU server, roughly 4× 80GB-class GPUs
Server memory in the hundreds of gigabytes or more, plus fast interconnect.
