Fine-tune your own Llama 2 to replace GPT-3.5/4

Fine-tuning open-source Llama 2 models can replace GPT-3.5 and GPT-4 for specific tasks, with a fine-tuned Llama 7B matching GPT-4 labels 95% of the time on a test set.

Most coverage came in the first two weeks

Teal is the weights (2023-07-18), amber triangles are 10 dated articles (each links to it), grey ticks are repo commits.

What people built on it

29 derivatives on the Hub. Which build to run, by runtime: the most downloaded in each class.

What the card says

1 cited sentence

Summary generated, cited

This model is converted for the Hugging Face Transformers format and is intended for English natural language generation tasks.[1][2]

  1. “converted for the Hugging Face Transformers format”
  2. “intended for commercial and research use in English”

Generated 2026-10-07 15:13 UTC by parasail-gemma-4-26b-a4b-it; each numeral points at the fact it rests on. Not a verdict.

Use-case evidence

2 use cases

What it is good at 2 use cases

Labels are evidence, not verdicts: measured a third-party leaderboard row for this model; author-reported a number the model author published in the card or eval files; structural a deterministic signal from the name, config or chat template, or a decision-model estimate. Each chip links to its source. All use cases.

The llama2.c repository offers a 700-line pure C file for training and inferring Llama 2 models, currently supporting fp32 inference for models up to 7B parameters. Work on model quantization is currently ongoing, but the project includes a 110M parameter model trained on the TinyStories dataset.written, reviewed, cited
  • Models larger than 7B are unusably slow because the repo performs float32 inference.
  • The 13B+ model variant fails due to integer flow errors in pointer arithmetic.

Khoj is an open-source, self-hostable AI platform that lets users get answers from the web or their docs. It enables building custom agents and scheduling automations while supporting online or local LLMs like gpt, claude, gemini, llama, qwen, and mistral. Users can get started for free and contribute to the community-sustained project.written, reviewed, cited

Ollama enables local execution of uncensored Llama 2 variants, such as the 7B model fine-tuned using Wizard-Vicuna conversation dataset and Nous Hermes Llama 2 13B fine-tuned on over 300,000 instructions. The 13B model stands out for its long responses, lower hallucination rate, and absence of OpenAI censorship mechanisms. Users can run these models via commands like ollama run llama2-uncensored to bypass standard safety refusals.written, reviewed, cited
  • The uncensored model provides a specific recipe for dangerously spicy mayo including ingredients like cayenne pepper and paprika.
  • The uncensored model describes the manufacturing process for Tylenol by combining paracetamol with aspirin, caffeine, and diphenhydramine.

Fine-tuning open-source Llama 2 models can replace GPT-3.5 and GPT-4 for specific tasks, with a fine-tuned Llama 7B matching GPT-4 labels 95% of the time on a test set. While fine-tuning requires 1000+ examples and is less flexible than prompting, a fine-tuned Llama 7B is 50x cheaper than GPT-3.5 per token, costing just $19 to classify 2M recipes versus $23k for GPT-4.written, reviewed, cited
