Model overview
> **23 official quantizations of fableforge-ai/Mythos-V2-9B** (Qwen3.5-9B — uncensored, 13.7/15 benchmark at Q4_K_M, hybrid linear-attention 256K arch). > **Imatrix note:** Low-bit `IQ1`/`IQ2`/`IQ3` quants are importance-matrix quantized (imatrix computed on 4.6 MB of general text). The final NextN/MTP block (`blk.32`) is quantized to `q8_0` in these files because it is never exercised during imatrix calibration. > **Speed (M3, Ollama):** Q4_K_M ≈ **2.8–3.5 tok/s** generation, ~45 tok/s prompt processing. Quantization > is not the bottleneck: Qwen3.5's hybrid linear-attention arch is slower per-token than dense Qwen3 in > Ollama/llama.cpp (dense 9B Q4s reach ~7 tok/s on the same hardware). Expect low-bit quants to score > below these numbers; Q4_K_M and above reproduce them faithfully.
Key features
特点摘要待依据来源补齐，不凭模型名称推断能力。
Limitations & considerations
Sources are insufficient to establish specific limitations. Verify task performance, latency, data policies, licensing and version lifecycle.
Source prices & cost analysis
Prices vary by channel, region and configuration. Channel quotes are listed independently and are not treated as a single official provider price.

Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
