AgentionAI โ€” Gyro 3.8 Flash Next

Qwen3.8-Flash-Next Gyro โ€” GGUF

Qwen3.8-Flash-Next (125B MoE) on one GPU: 27.6 GiB for a 32 GB card, 35 GiB for 48 GB, 50 GiB for 64 GB.

Headline Detail
221 tok/s on one RTX 5090 (Gyro-S, fully VRAM-resident, Strata); 218 tok/s with the MTP draft in agentionai/llama.cpp
98% of Q4 accuracy at half the memory MMLU-Pro: Gyro-M 80.0 vs 81.4 for our 67 GiB AP-Q4_K_XL, in 35 GiB
30 / 30 LiveCodeBench problems Gyro-M, given room to reason (128k tokens); 90% at a 64k limit
New: Gyro-L for 64 GB KLD 0.146 in 50.2 GiB: ahead of ggml-org IQ4_NL (0.200, 68.2 GiB) and AtomicChat Q4_K_M (0.228, 52.3 GiB)
Updated Gyro-S, same size KLD 0.401, 0 loops in a 45-run loop stress test; ahead of ISTA IQ2_XS with 24% less memory
0 loops in 10 long-reasoning runs Gyro-M; a well-known 2-bit quant looped 7 times and finished only 6
Updated Gyro-M, same size KLD 0.291: ahead of ISTA-DASLab IQ3_XXS (0.311) with 20% less memory and unsloth UD-Q2_K_XL (0.334) with 25% less; 0 loops in a 45-run loop stress test

The best quality per GiB at every size we ship. Gyro-S fits a 32 GB card: 27.64 GiB of weights, 28.8 GiB at 64k context, up to 128k context.

Abliterated Gyro-S and Gyro-M: agentionai/Qwen3.8-Flash-Next-Gyro-abliterated-Huihui-GGUF. The routed experts are stored in a rotated basis with our own rotor code (Agention Precision Rotor, APR). The TQ1_0 / TQ2_0 / TQ3_0 in the names is only a size class for the Hub (the experts use the trellis types TQK6/TQK7, TQ2_T and TQP5-7). Upstream llama.cpp cannot load these files yet. They run in:

  • Strata 0.2.0 or newer: app, Terminal and engine for NVIDIA and AMD RX 7000 / RX 9000 / R9700
  • halo-box/strix-llama.cpp master: CPU, Vulkan and HIP, made for AMD Strix Halo
  • agentionai/llama.cpp and its container: CPU, Vulkan and CUDA; also runs the MTP draft

Long reasoning without loops. One-shot coding prompt (a voxel pagoda scene), 10 seeds: looping traces Gyro-M 0/10 (first release), ISTA IQ2_XS 7/10; updated Gyro-S 2/20 (20 seeds, --min-p 0.05; both runs still finished); updated Gyro-M 0/5 (5 seeds, --min-p 0.05). Loop stress test (45 runs of prompts that provoke runaway generation, --min-p 0.05): updated Gyro-S 0 loops, updated Gyro-M 0 loops. MMLU-Pro: Gyro-M 80.0, Gyro-S 78.1 (both first release), AP-Q4_K_XL 81.4, all within noise at our 70-question sample. LiveCodeBench v6 (30-problem subset, one seed): Gyro-M 90% at a 64k token limit and 30/30 when its long answers get 128k; Gyro-S 67% at 64k, 83% at 128k (both first release; not re-run on the updates).

Gyro-L: use Qwen3.8-Flash-Next-Gyro-L-TQ3_0.gguf in place of the Gyro-S file (pull the image again first).

NVIDIA: replace --device /dev/dri --group-add ... with --gpus all -e NVIDIA_DRIVER_CAPABILITIES=all (Vulkan), or build agentionai/llama.cpp with -DGGML_CUDA=ON for full speed.

Strata (NVIDIA, AMD RX 7000 / RX 9000 / R9700):

Strata is the fastest way to run Gyro on an RTX 5090, and its expert cache keeps the most-used experts on the GPU, which makes 24 GB cards practical. Since 0.2.0 it is an app, a Terminal and an engine, and the installers carry the engine. Pick the file for your card on the release page, or install the Terminal:

curl -fsSL https://github.com/Niko1221/Strata/releases/latest/download/install.sh | sh
strata launch                                                             # suggests a model for your memory and serves it
strata launch --model-path ~/models/Qwen3.8-Flash-Next-Gyro-S-TQ1_0.gguf  # files you already have

Web chat at http://127.0.0.1:8080, OpenAI-compatible API at http://127.0.0.1:8080/v1. Measured with Strata (tok/s, prose / JSON / code): RTX 5090 140 / 221 / 209.

strix-llama.cpp (AMD Strix Halo; CPU, Vulkan, HIP):

git clone https://github.com/halo-box/strix-llama.cpp && cd strix-llama.cpp
cmake -B build -DGGML_VULKAN=ON && cmake --build build -j --target llama-server   # HIP: -DGGML_HIP=ON -DGPU_TARGETS=gfx1151

Tested with Gyro-S and Gyro-M (Vulkan); Gyro-L not tested yet.

Recommended settings

  • Sampling: --temp 1.0 --top-p 0.95 --top-k 20 --min-p 0.05 (Qwen's thinking settings plus min-p).
  • Keep --ngram-on-disk (fast direct reader, Linux and Windows), with the model on fast NVMe. Older Windows builds: leave it out, and the table is read on demand (--lazy-mode on).
  • MTP draft: --spec-type draft-mtp -md mtp-Qwen3.8-Flash-Next-draft.gguf --spec-draft-n-max 6 --spec-draft-n-min 2 --spec-draft-mtp-vocab 32768 (adds ~3.75 GiB: on a 32 GB card, 24k context with the draft, 128k without, or the draft on a second GPU). The draft was updated on 2026-10-05 to upstream llama.cpp's tensor names (weights unchanged): it needs agentionai/llama.cpp main or the container from 2026-10-05 or later; older builds fail to load it, so update.
  • Container images from before 2026-10-09 could answer HTTP 500 when several requests run at once with the MTP draft: pull the current agentionai/agention-llama:server from Docker Hub (on an older image, add -e LLAMA_GRAPH_SLOTS=0). The image is mirrored on Docker Hub while ghcr.io/agentionai/agention-llama is not being updated.
  • CUDA builds from before 2026-10-04 could crash with several long prompts at once: update agentionai/llama.cpp (on an older build, GGML_CUDA_TQ_MMQ=0 or --parallel 1).

Changelog

  • 2026-10-19: more engines. Gyro runs in Strata 0.2.0 and in halo-box/strix-llama.cpp master, besides our own build. Files unchanged.
  • 2026-10-13: Gyro-L file updated with an 8-bit n-gram table: same GPU memory (50.21 GiB), KLD 0.146 (held-out), 0.027 (code). The table stays on disk; the download is now 108 GB. Download the file again.
  • 2026-10-12: Gyro-L added (Qwen3.8-Flash-Next-Gyro-L-TQ3_0.gguf, 50.21 GiB GPU weights). Needs the agentionai/agention-llama:server container from 2026-10-12 or later, or a current build of agentionai/llama.cpp main; older builds cannot load it. Tested on Strix Halo (Vulkan).
  • 2026-10-11: Gyro-M updated. Same file name, size, format and speed; better weights from an improved encode. KLD 0.291 (held-out), 0.066 (code); 0 loops in a 45-run loop stress test. Download the file again; the first release stays available as revision ae0277db.
  • 2026-10-10: Gyro-S updated. Same file name, size, format and speed; better weights from an improved encode. KLD 0.401 (held-out), 0.109 (code); 0 loops in a 45-run loop stress test. Download the file again; the first release stays available as revision aba94138.

Status

Runs on agentionai/llama.cpp (Vulkan, CUDA), Strata and strix-llama.cpp; tested on Linux with Strix Halo, R9700, RTX 5090, RTX A6000 and RTX 3090. Coming: Gyro Coder, Gyro Signal (shorter answers, no extra loops). The weights come from our own encoder, which we are not publishing at this stage.

Credits

Tensor format: trellis-coded quantization with Hadamard rotation, in the family of QTIP (Tseng et al., 2024). Encoder, trellis types and kernels: AgentionAI. Base model: Qwen/Qwen3.8-Flash-Next. Runtimes: llama.cpp, Strata, strix-llama.cpp.

Support AgentionAI

These quants are released freely. If they save you VRAM or make Qwen more useful, you can buy me a coffee or some GPU time and sponsor continued quantization and benchmarking on GitHub. AgentionAI is a one-person team and can use your help.
