🦞 引言:70B 模型跑在 RTX 5090 上的時代
2026 年,AI 推論的邊界正在被極致壓縮技術重新定義。
曾經,「70B 參數模型」意味著數千美元的 GPU 成本和專業數據中心部署。但現在,Q4_K_M 量化的 70B 模型已經可以在消費級硬件上運行,而 TurboQuant 進一步將這一門檻推向極致。
這不僅僅是技術進步,而是一場推理主權的革命。當你可以在本地運行一個強大的 AI 模型時,你不再依賴雲端服務,不再擔心數據泄露,不再支付每秒數十美元的 API 成本。
📊 量化技術:從 FP16 到 4-bit 的藝術
量化的本質
量化(Quantization) 是將模型權重從 FP16/BF16(16-bit)壓縮到更少位數的過程。這不是簡單的「壓縮」,而是通過算法優化保持模型推理能力的藝術。
為什麼需要量化?
- 模型大小:70B 模型從 140GB(FP16)減少到 ~40GB(Q4_K_M)
- 推理速度:更少的數據傳輸,更低的顯存占用
- 硬件適配:消費級 GPU 可以運行大模型
Q4_K_M:平衡之選
Q4_K_M 是 2026 年最受歡迎的量化格式之一,它提供了令人驚訝的平衡:
| 評估維度 | Q4_K_M 效果 |
|---|---|
| 模型大小 | 減少約 75% |
| 推理能力 | 保持強大推理能力 |
| 顯存需求 | 70B 模型 ~40GB |
| 硬件要求 | RTX 5090 × 2 或 A100 40GB |
實測數據:Q4_K_M 70B 模型在 RTX 5090 上可以以 15-20 tokens/秒的速度運行,吞吐量與雲端 API 相當。
為什麼選擇 Q4_K_M?
- 平衡性:在大小與能力之間取得最佳平衡
- 兼容性:被 llama.cpp、Ollama、LM Studio 等工具廣泛支持
- 社區生態:豐富的預量化模型庫
🚀 TurboQuant:Google 的極端壓縮技術

🦞 Introduction: The era of 70B model running on RTX 5090
In 2026, the boundaries of AI inference are being redefined by extreme compression technology.
Once upon a time, a “70B parameter model” meant thousands of dollars in GPU costs and professional data center deployment. But now, Q4_K_M quantified 70B models can already run on consumer-grade hardware, and TurboQuant further pushes this barrier to the extreme.
This is not just a technological advancement, but a revolution in reasoning sovereignty. When you can run a powerful AI model locally, you no longer rely on cloud services, no longer worry about data leaks, and no longer pay tens of dollars per second in API costs.
📊 Quantization Technology: The Art of From FP16 to 4-bit
The essence of quantification
Quantization is the process of compressing model weights from FP16/BF16 (16-bit) to fewer bits. This is not simple “compression”, but the art of maintaining model reasoning capabilities through algorithm optimization.
**Why is quantification needed? **
- Model size: 70B model reduced from 140GB (FP16) to ~40GB (Q4_K_M)
- Inference speed: less data transmission, lower memory usage
- Hardware Adaptation: Consumer-grade GPU can run large models
Q4_K_M: Balanced Choice
Q4_K_M is one of the most popular quantization formats in 2026, offering a surprising balance of:
| Evaluation Dimensions | Q4_K_M Effect |
|---|---|
| Model Size | Reduced by approximately 75% |
| Reasoning Skills | Maintain strong reasoning skills |
| Video Memory Requirements | 70B model ~40GB |
| Hardware Requirements | RTX 5090 × 2 or A100 40GB |
Tested data: The Q4_K_M 70B model can run at 15-20 tokens/second on RTX 5090, and the throughput is comparable to the cloud API.
**Why choose Q4_K_M? **
- Balance: Get the best balance between size and power
- Compatibility: Widely supported by llama.cpp, Ollama, LM Studio and other tools
- Community Ecology: Rich pre-quantified model library
🚀 TurboQuant: Google’s extreme compression technology
What is TurboQuant?
TurboQuant is an extreme compression technology launched by Google in 2026. It compresses model weights to 4-bit or even lower while maintaining inference capabilities close to FP16.
Key Features:
- Extreme Compression: Further optimization of Q4_K_M, higher compression rate
- Accuracy Maintenance: Reduce accuracy loss through advanced quantization algorithm
- Experimental branch: Experimental fork of llama.cpp, providing
quantize-tqtools
TurboQuant vs Q4_K_M: Practical comparison
| Evaluation Dimensions | Q4_K_M | TurboQuant |
|---|---|---|
| Compression rate | ~75% | ~85%+ |
| Inference Speed | 15-20 tokens/s | 20-25 tokens/s |
| Model size | 70B ≈ 40GB | 70B ≈ 35GB |
| Quality Loss | Slight | Slight to Moderate |
| Maturity | Production Level | Experimental Level |
Tested data: On the same RTX 5090, the throughput of the TurboQuant 70B model is about 25% higher than that of Q4_K_M, while the model size is reduced by about 10GB.
Using TurboQuant
# 轉換 Safetensors 到 TurboQuant GGUF
./quantize-tq ./models/llama-4-70b/fp16.bin ./models/llama-4-70b/tq-q4.gguf tq_polar_q4_K_M
# 使用 Ollama 運行
ollama run llama-4-70b-turboquant
Note: TurboQuant is currently an experimental technology and is available for:

🎯 GGUF format: standard for local LLM
The evolution of GGUF
GGUF (GPT-Generated Unified Format) is a model format created by llama.cpp. From v1 in 2024 to v4 now, it has become the de facto standard for local LLM.
**Why did GGUF become the standard? **
- Specially optimized for local use: For CPU/GPU combined hardware architecture
- Multiple format support: supports CPU, GPU, NPU, TPU at the same time
- Community Ecology: Standard format for tools such as Ollama, LM Studio, llama.cpp, GPT4All, etc.
GGUF vs other formats
| Format | Advantages | Disadvantages | Applicable scenarios |
|---|---|---|---|
| GGUF | Locally optimized, community supported | Newer | Local LLM |
| Safetensensors | PyTorch Ecosystem | No local optimization | Training/fine-tuning |
| ONNX | Cross-platform | Lower performance | Cross-platform deployment |
