Fine-tuned Llama 2 70B with Jon Durbin's self-instruct training methodology
Jon Durbin & Self-Instruct Methodology
Jon Durbin is an independent AI researcher who created Airoboros as a demonstration that high-quality open-source language models could be trained using synthetic data generated by GPT-4. His key insight was that by carefully prompting GPT-4 with diverse instruction templates, he could generate a training dataset rich in creative writing, roleplay, reasoning, and general instruction-following tasks -- then use this data to fine-tune open base models like Llama 2 70B.
The name "Airoboros" is a play on "ouroboros" (the serpent eating its own tail), reflecting the self-referential nature of the training methodology where AI-generated data is used to train AI models. Durbin published his complete training pipeline as open source on GitHub (jondurbin/airoboros), making it one of the earliest fully transparent self-instruct implementations for large models.
The approach built on the Self-Instruct methodology described by Wang et al. (2022) in their foundational paper, but Durbin extended it significantly by using GPT-4 as the generation backbone (rather than text-davinci-003), adding custom instruction categories for creative tasks, and iterating across multiple data versions (1.4, 2.0, 2.1, 2.2.1) with progressively better filtering and deduplication.
Why Airoboros Mattered Historically
In mid-2023, Airoboros was one of the first models to demonstrate that:
- Self-instruct works at 70B scale: Generating training data with GPT-4 and fine-tuning a 70B model produced genuinely capable results
- Creative quality can rival general benchmarks: Users consistently rated Airoboros highly for storytelling despite modest MMLU scores
- Open-source training pipelines matter: Durbin's published code enabled others to create their own self-instruct datasets
- Iterative data refinement beats more data: Each Airoboros version improved through better filtering, not larger datasets
Technical Foundation
Key research and resources behind Airoboros-70B:
- Llama 2: Open Foundation and Fine-Tuned Chat Models - Base architecture (Touvron et al., 2023)
- Airoboros Project Repository - Jon Durbin's open-source training code and methodology
- Jon Durbin on HuggingFace - All Airoboros model variants and documentation
- Self-Instruct: Aligning Language Models with Self-Generated Instructions - Foundational self-instruct research (Wang et al., 2022)

Important Note on License
Airoboros-70B uses the Llama 2 Community License, which is not a standard open-source license. Commercial use is restricted for applications with more than 700 million monthly active users. Additionally, since the training data was generated by GPT-4, OpenAI's Terms of Service may impose further restrictions on commercial use of model outputs. For fully permissive commercial use, consider newer models like Llama 3.1 (more permissive license) or Qwen 2.5 (Apache 2.0).
Airoboros Training Pipeline
Jon Durbin's training pipeline for Airoboros is a multi-stage process that transforms GPT-4 outputs into a curated fine-tuning dataset. Understanding this pipeline is valuable for anyone building their own self-instruct datasets.
Step 1: Instruction Seed Generation
Durbin created a set of instruction category templates covering creative writing, coding, reasoning, roleplay, trivia, summarization, and more. Each category had specific prompting strategies to elicit diverse, high-quality outputs from GPT-4. The category system ensured the training data covered a wide range of tasks rather than clustering around common patterns.
Step 2: GPT-4 Data Generation
Using the OpenAI API, instructions were sent to GPT-4 with carefully crafted system prompts for each category. The generation process produced instruction-response pairs in a structured format. Durbin emphasized quality over quantity -- the dataset (airoboros-gpt4-1.4.1) contained thousands of carefully generated examples rather than millions of noisy ones.
Step 3: Data Filtering & Curation
Each version of Airoboros improved the filtering pipeline. Low-quality responses, duplicates, responses containing GPT-4 refusals or safety disclaimers, and examples with formatting issues were removed. Later versions (2.1, 2.2.1) added decontamination checks to remove benchmark test questions from the training data, ensuring benchmark scores were not artificially inflated.
Step 4: Fine-Tuning on Llama 2 70B
The curated dataset was used to fine-tune Meta's Llama 2 70B base model using standard supervised fine-tuning (SFT). Training was done with full-precision parameters (not LoRA), requiring significant GPU resources. The resulting model weights were published on HuggingFace for the community to download, quantize, and deploy locally.
Key Dataset: jondurbin/airoboros-gpt4-1.4.1
The primary training dataset is available on HuggingFace asjondurbin/airoboros-gpt4-1.4.1. It contains instruction-response pairs across categories including: creative writing, roleplay, coding, reasoning, trivia, summarization, rewriting, and more. This dataset became a reference implementation for the community, inspiring similar self-instruct projects like Orca, WizardLM, and others that used GPT-4 outputs for training.

Troubleshooting & Common Issues
Out of Memory (OOM) Errors
The most common issue with 70B models. If your GPU runs out of VRAM, try these solutions:
Solutions:
- * Use a more aggressive quantization (Q4_K_M or Q2_K)
- * Reduce context length below 4096 (e.g., -c 2048)
- * Offload some layers to CPU with llama.cpp (-ngl flag, use fewer layers)
- * Use split mode across multiple GPUs if available
- * Accept that a single 24GB GPU cannot run 70B models
Slow Inference Speed
70B models are inherently slow. Expect 5-15 tokens/second on good hardware. Some tips to improve speed:
Optimization Tips:
- * Keep as many layers on GPU as possible (-ngl 80 or higher)
- * Use Q4_K_M instead of higher quantizations for better speed
- * Reduce context window if you don't need full 4096 tokens
- * Use flash attention if your backend supports it
- * On Apple Silicon, ensure using Metal backend (automatic in llama.cpp)
Ollama Model Not Found
If ollama run airoboros doesn't offer the 70B variant, create a custom model:
Steps:
- * Download the GGUF file from HuggingFace (TheBloke/Airoboros-L2-70B-GGUF)
- * Create a Modelfile:
echo "FROM ./airoboros-l2-70b.Q4_K_M.gguf" > Modelfile - * Build the model:
ollama create airoboros-70b -f Modelfile - * Run it:
ollama run airoboros-70b
2026 Honest Assessment
Should You Use Airoboros-70B in 2026?
Honest answer: probably not for new projects. Airoboros-70B is historically significant as one of the first models to prove that self-instruct with GPT-4 works at 70B scale. Jon Durbin's open pipeline inspired a generation of community fine-tunes. However, the local AI landscape has advanced dramatically since mid-2023, and newer models surpass Airoboros on virtually every metric.
Historical Significance
Airoboros deserves recognition as a pioneer. In mid-2023, it demonstrated that an individual researcher could create a competitive 70B model using synthetic data -- at a time when most assumed you needed massive human-labeled datasets. This insight influenced later projects like Orca, WizardLM, and the broader synthetic data movement. Jon Durbin's published code and datasets remain valuable educational resources for anyone learning about self-instruct fine-tuning.
Why You Should Use Something Else
- *MMLU 64% vs 86%: Qwen 2.5 72B scores 22 percentage points higher on MMLU with similar VRAM
- *4K vs 128K context: Modern models offer 32x more context window at the same parameter count
- *Non-commercial license: Llama 2 Community License restricts commercial use; newer alternatives use Apache 2.0
- *40GB+ VRAM minimum: Same VRAM requirement as newer, far more capable models
- *No active development: Last version (2.2.1) released October 2023; no updates expected
When Airoboros Still Makes Sense
- *Creative writing niche: Some users still prefer Airoboros's storytelling style for roleplay and fiction
- *Learning self-instruct: Studying Durbin's pipeline is an excellent way to learn synthetic data generation
- *Existing deployments: If already deployed and working for your specific use case, migration may not be worth it
- *Research purposes: Comparing self-instruct models across different eras and methodologies
Recommended Upgrade Path
If you are currently using Airoboros-70B, the best upgrade in 2026 is Qwen 2.5 72B(Apache 2.0 license, MMLU ~86%, 128K context, similar VRAM at Q4) or Llama 3.1 70B(more permissive license than Llama 2, MMLU ~79%, 128K context). Both are available through Ollama and require the same hardware as Airoboros-70B.

Frequently Asked Questions
What is Airoboros-70B and who created it?
Airoboros-70B is a 70-billion parameter language model created by Jon Durbin. It is a fine-tune of Meta's Llama 2 70B, trained using Jon Durbin's novel self-instruct methodology where high-quality instruction data was generated using GPT-4 outputs with careful curation. The model is particularly known for its creative writing and roleplay capabilities.
What are the VRAM requirements for running Airoboros-70B locally?
Airoboros-70B requires significant VRAM. At Q4_K_M quantization (the most common balance of quality and size), you need approximately 40GB VRAM. Q2_K (lowest quality) needs around 28GB, Q5_K_M needs about 48GB, Q8_0 needs approximately 70GB, and full FP16 precision requires around 140GB. Most consumer GPUs cannot run this model -- you typically need an RTX A6000 (48GB), dual RTX 3090s, or an Apple M2 Ultra with 64GB+ unified memory.
How does Airoboros-70B perform on standard benchmarks?
On the HuggingFace Open LLM Leaderboard, Airoboros-70B scores approximately 63-65% on MMLU, 67% on ARC, 86% on HellaSwag, and 56% on TruthfulQA, for an overall average around 68%. These are solid scores for a community fine-tune, though not state-of-the-art compared to newer 70B models.
What license does Airoboros-70B use?
Airoboros-70B uses the Llama 2 Community License, inherited from its Llama 2 70B base model. This license restricts commercial use -- applications with over 700 million monthly active users require a separate license from Meta. It is not a permissive open-source license like MIT or Apache 2.0.
What is the context window of Airoboros-70B?
Airoboros-70B has a 4,096 token context window, inherited from the Llama 2 base model. This is relatively limited compared to newer models (Llama 3.1 supports 128K tokens). The 4K context means you can process roughly 3,000 words of combined input and output per request.
Can I run Airoboros-70B with Ollama?
Ollama has an 'airoboros' model available (run with 'ollama run airoboros'), but the 70B variant may not be directly available through Ollama's library. You can download GGUF quantized files from HuggingFace (e.g., from TheBloke) and create a custom Ollama model using a Modelfile. Alternatively, use llama.cpp directly with GGUF files for more control.
What are the different Airoboros versions?
Jon Durbin released multiple Airoboros versions: 1.4 (early release), 2.0 (improved training data), 2.1 (refined methodology), and 2.2.1 (latest iteration with best data quality). Model names on HuggingFace include airoboros-l2-70b, airoboros-l2-70b-2.1, and airoboros-l2-70b-2.2.1. Later versions generally have improved instruction following and fewer hallucinations.
