Starling LM 7B Beta — Hardware Requirements & GPU Compatibility
ChatStarling-LM-7B-beta is Nexusflow's chat model, fine-tuned from Openchat-3.5-0106 (itself based on Mistral-7B-v0.1) using reinforcement learning from AI feedback (RLAIF). It was trained with Nexusflow's own 34B reward model and a PPO-based policy optimization pipeline on the Nectar preference dataset, and scored 8.12 on MT-Bench with GPT-4 as judge, an improvement over the team's earlier Starling model. It uses OpenChat's exact chat template rather than a generic one. At 7 billion parameters it runs comfortably on a single consumer GPU. Context length is 8,192 tokens. It is released under the Apache 2.0 license with an added condition that it not be used to compete with OpenAI, reflecting that its Nectar training data was generated with GPT-4. It was published in March 2024.

Frequently Asked Questions
- How much VRAM does Starling LM 7B Beta need?
Starling LM 7B Beta requires 4.9 GB of VRAM at Q4_K_M, or 15.1 GB at BF16. Full 8K context adds up to 0.8 GB (5.7 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 7.2B × 4.8 bits ÷ 8 = 4.3 GB
KV Cache + Overhead ≈ 0.6 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 1.4 GB (at full 8K context)
VRAM usage by quantization
Q4_K_M4.9 GBQ4_K_M + full context5.7 GB- What's the best quantization for Starling LM 7B Beta?
For Starling LM 7B Beta, Q4_K_M (4.9 GB) offers the best balance of quality and VRAM usage. Q5_0 (5.1 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 3.6 GB.

- Can I run Starling LM 7B Beta on a Mac?
Starling LM 7B Beta requires at least 3.6 GB at Q2_K, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run Starling LM 7B Beta locally?
Yes — Starling LM 7B Beta can run locally on consumer hardware. At Q4_K_M quantization it needs 4.9 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Starling LM 7B Beta?
At Q4_K_M, Starling LM 7B Beta can reach ~978 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~133 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: NVIDIA B200 → 8000 ÷ 4.9 × 0.65 = ~1059 tok/s
