+ This is Phind v2 QLoRa finetune using my PythonTutor LIMA dataset:
7
+ https://huggingface.co/datasets/KrisPi/PythonTutor-LIMA-Finetune
8
+
9
+ My shy attempt to democratize task-specific, cheap fine-tuning focused around LIMA-like datasets -everybody can afford to generate them (less than 20$) and everybody can finetune them (7 hours in total using 2x3090 GPU ~3$+5$ on vast.ai)
10
+
11
+ At the moment of publishing this adapter, there are already production-ready solutions for serving several LorA adapters. I honestly believe that the route of a reproducible, vast collection of adapters on the top of current SOTA models, will enable the open-source community to access GPT-4 level LLMs in the next 12 months.
12
+
13
+ My main inspirations for this were blazing fast implementation of multi-LORA in Exllamav2 backend, Jon's LMoE and Airoboros dataset, r/LocalLLaMA opinions around models based on LIMA finetunes, and of course the LIMA paper itself.
14
+ To prove the point I'm planning to create a few more finetunes like this, starting with the Airoboros "contextual" category for RAG solutions, adapters for React and DevOps YAML scripting.
15
+
16
+ 5 epochs, LR=1e-05, batch=2, gradient accumulation 32 (i.e. trying to simulate batch 64), max_len=1024. Rank and Alpha both 128 targeting all modules. trained in bfloat16. Constant schedule, no warm-up.
17
+ Flash-Attention 2 turned off due to an issue with batching

+ Evals:
20
+ HumanEval score (2.4 p.p improvement to best Phind v2 score!) for the new prompt:
21
+ **{'pass@1': 0.7621951219512195}**
22
+ **Base + Extra**
23
+ **{'pass@1': 0.7073170731707317}**
24
+ Base prompt (0.51 p.p improvement)
25
+ {'pass@1': 0.725609756097561}
26
+ Base + Extra
27
+ {'pass@1': 0.6585365853658537}
28
+ Phind v2 with Python Tutor custom prompt is only getting:
29
+ {'pass@1': 0.7073170731707317}
30
+ Base + Extra
31
+ {'pass@1': 0.6463414634146342}
32
+ After several HumanEval tests and prompts Phind v2 was maximum able to score: 73.78%
33
+ **All evals using Transformers 8bit**

35
+ In the long term, I'm planning on experimenting with LIMA + DPO Fine-Tuning, but so far I noticed that LIMA datasets need to be both general and task-specific. The best result I got with around 30% of samples that were task specific.
