Show HN: Open-source engine running Gemma 4 26B in 2 GB RAM on any M-series Mac

TurboFieldfare enables Gemma 4 26B-A4B inference on Apple Silicon Macs with only 8 GB of RAM by streaming experts from the SSD instead of loading the full model.

  • The installer never materializes the full source checkpoint and streams required byte ranges directly into the .gturbo layout.
  • The loopback server has no remote authentication or TLS and the client must authorize and run every tool call.

Show HN: Cactus Hybrid: We taught Gemma 4 to know when it's wrong

Cactus Hybrid introduces on-device models that score every answer with a confidence between 0 and 1 to decide when to hand off to a bigger model.

  • Weights on the meta device crash the confidence read because probes score generations outside the module forward path.
  • The probe is a patch you compile into the llama.cpp engine rather than a standalone library component.

Where it's used

Hugging Face does not say who downloads a model or with what. These are the proxies: API providers listing it, quantized builds, fine-tunes/adapters/merges, and Spaces that load it.

No API provider serves it, so its downloads are people running it themselves: 11 quantized builds and 4 Spaces.

Google released new Gemma 4 checkpoints optimized with Quantization-Aware Training to improve efficiency on edge devices and consumer GPUs. The E2B model achieves a 1GB memory footprint using a mobile-specialized schema that applies targeted 2-bit quantization to token generation layers. Developers can access GGUF formats ready for llama.cpp and MTP QAT checkpoints to preserve inference speedups while running locally.written, reviewed, cited
  • The mobile-specialized schema pre-calculates activation scaling settings during training to reduce workload on mobile chips.
  • Targeted 2-bit quantization compresses token generation parts while keeping core reasoning layers at higher precision.
  • Deploying only needed modalities allows the Gemma 4 E2B text-only model to require less than 1 GB of memory.

Google released Multi-Token Prediction (MTP) drafters for the Gemma 4 family under the same open-source Apache 2.0 license as Gemma 4. These drafters deliver up to a 3x speedup for models like the 26B MoE and 31B Dense versions without quality degradation. Benchmarks on hardware such as the NVIDIA RTX PRO 6000 show that increasing batch sizes to 4 to 8 unlocks up to a ~2.2x speedup locally.written, reviewed, cited
  • The MTP drafter shares the target model's KV cache to avoid recalculating context the larger model has already processed.
  • For E2B and E4B edge models, an efficient clustering technique in the embedder accelerates generation where logit calculation is a bottleneck.
  • The 26B mixture-of-experts model presents unique routing challenges at a batch size of 1 on Apple Silicon.

TurboFieldfare enables Gemma 4 26B-A4B inference on Apple Silicon Macs with only 8 GB of RAM by streaming experts from the SSD instead of loading the full model. The runtime maintains ~2 GB of weights and a 4K KV cache in memory, achieving 5.1-6.3 tok/s on an 8 GB M2 MacBook Air and 31-35 tok/s on a 24 GB M5 Pro. The complete installation occupies about 14.3 GB for the text model plus optional image packs.written, reviewed, cited
  • The installer never materializes the full source checkpoint and streams required byte ranges directly into the .gturbo layout.
  • The loopback server has no remote authentication or TLS and the client must authorize and run every tool call.
  • The image tower requires an M2 or newer Apple Silicon Mac while text-only inference remains available on M1.

Engineers can run Google's Gemma 4 26B-A4B model on a 13-year-old dual Xeon E5-2690 v2 server without a GPU by using the ik_llama.cpp fork with GGML_USE_IQK_MULMAT disabled. The system achieves approximately 5.2 tokens per second for decoding and 16 tokens per second for prompt evaluation when quantized to Q8_0. This repurposed HP StoreVirtual box costs under $300 and operates using only AVX1 instruction sets.written, reviewed, cited
  • The graph builder emits MOE_FUSED_UP_GATE and FUSED_UP_GATE ops unconditionally even when AVX2 instructions are unavailable.
  • Disabling --run-time-repack is mandatory because it reorders weights into an AVX2-only layout that garbles output on AVX1 hardware.
  • The fix splits combined up_gate_exps tensors into two separate slices to run distinct mul-mat-IDs instead of relying on fused kernels.

Cactus Hybrid introduces on-device models that score every answer with a confidence between 0 and 1 to decide when to hand off to a bigger model. The Gemma 4 E2B Hybrid model matches Gemini 3.1 Flash-Lite performance by routing only 15–55% of queries to the cloud while running the rest locally. It is MIT-licensed and achieves a 0.770 AUROC on MMLU, with a probe trained on zero audio data yet reaching 0.79–0.88 AUROC on four audio benchmarks.written, reviewed, cited
  • Weights on the meta device crash the confidence read because probes score generations outside the module forward path.
  • The probe is a patch you compile into the llama.cpp engine rather than a standalone library component.
  • Transformers version 5.14 and above cause a segfault on this specific checkpoint.
