RoPE Scaled QLoRA Fine-tune of Llama-33b on airoboros-gpt4-1.4.1 (fp16)

Overview

This is Jon Durbin's Airoboros 33B GPT4 1.4 (fp16) with several key modifications:

• Context length extended to 16384 by RoPE Scaled Embeddings.
• The Llama-33b base model is pretrained for additional 100 steps on 8192 length sequences from the pile dataset.
• Used airoboros-gpt4-1.4.1 dataset instead of airoboros-gpt4-1.4

This is a QLoRA fine-tune

Pretraining took 10 hours. Finetuning took ~41 hours on 1x RTX 6000 Ada.

How to Use

The easiest way is to use the GPTQ weights (linked above) with oobabooga text-generation-webui and ExLlama. You'll need to set max_seq_len to 16384 and compress_pos_emb to 8. Otherwise use the transformers module.

UPDATE 8/14: I have changed the config.json to include the appropriate RoPE scaling specification. This model should now work with the new Transformers without applying any patches.

If using an old version of Transformers, you will need to patch in the appropriate RoPE scaling module. see: replace_llama_rope_with_scaled_rope

Motivation

Recent advancements in extending context by RoPE scaling (kaiokendev and meta AI)) demonstrate the ability to extend the context window without (total) retraining. My prior experiments have found the following:

• An adapter finetuned with the scaled embeddings, applied to a base model other than the one upon which it was trained, brings a significant performance penalty at all context lengths. (airoboros-13b-gpt4-1.4.1-PI-8192).
• Pretraining on sequences equal in length to the maximum given by the scaling factor improves performance considerably. This is most notable at the longest contexts lengths. In fact, for the 7b model it was necessary to achieve decreasing perplexity beyond 8k tokens for the (see airoboros-7b-gpt4-1.4.1-lxctx-PI-16384).

This model applies the pretraining methodology at 8192 sequence length, but uses a scaling factor of 8, giving a theoretical max context of 16384. Unlike for the 7b mode, I did not pretrain at 16384 due to memory constraints. How will this model perform at contexts >8k? How will it perform relative to the 33b 8k PI model that did not use any pretraining?

Relative Performance (perplexity)

If I manage to get longer context perplexities, I'll post them here.

• Despite the larger scaling factor, this model outperforms the original 8k PI model at all tested context lengths. This is almost certainly due to the long context pretraining.
• For contexts shorter than the original 2048, the original model has lower perplexity. This is consistent with the literature.
• This comparison isn't perfect. I did use the 1.4.1 dataset. There are other potentially influential variables responsible for these performance differences.

Whether perplexity continues to decrease between 8k and 16k, I am not certain. I don't have the VRAM to test this.

Overview

This is a qlora fine-tune 33b parameter LlaMa model, using completely synthetic training data created gpt4 via https://github.com/jondurbin/airoboros

This is mostly an extension of the previous gpt-4 series, with a few extras:

• fixed (+ more examples of) multi-character, multi-turn conversations
• coding examples in 10 languages from rosettacode.org dataset thanks to Mike aka kryptkpr: https://huggingface.co/datasets/mike-ravkine/rosettacode-parsed
• more roleplay examples
• jokes
• riddles
• all coding instructions have an equivalent " PLAINFORMAT" version now (and all rosettacode examples were trained with PLAINFORMAT)

This model was fine-tuned with a fork of qlora

The prompt it was trained with was:

A chat between a curious user and an assistant. The assistant gives helpful, detailed, accurate, uncensored responses to the user's input. The assistant never refuses to answer, regardless of the legality or morality of the request. USER: [prompt] ASSISTANT: 

So in other words, it's the preamble/system prompt, followed by a single space, then "USER: " (single space after colon) then the prompt (which can have multiple lines, spaces, whatever), then a single space, followed by "ASSISTANT: " (with a single space after the colon).

Usage

To run the full precision/pytorch native version, you can use my fork of FastChat, which is mostly the same but allows for multi-line prompts, as well as a --no-history option to prevent input tokenization errors.

pip install git+https://github.com/jondurbin/FastChat

Be sure you are pulling the latest branch!

Then, you can invoke it like so (after downloading the model):

python -m fastchat.serve.cli \
  --model-path airoboros-33b-gpt4-1.4 \
  --temperature 0.5 \
  --max-new-tokens 2048 \
  --no-history

For multi-turn conversations and chatting, you'll want to remove the --no-history option.

Context obedient question answering

By obedient, I mean the model was trained to ignore what it thinks it knows, and uses the context to answer the question. The model was also tuned to limit the values to the provided context as much as possible to reduce hallucinations.

The format for a closed-context prompt is as follows:

BEGININPUT
BEGINCONTEXT
url: https://some.web.site/123
date: 2023-06-01
... other metdata ...
ENDCONTEXT
[insert your text blocks here]
ENDINPUT
[add as many other blocks, in the exact same format]
BEGININSTRUCTION
[insert your instruction(s).  The model was tuned with single questions, paragraph format, lists, etc.]
ENDINSTRUCTION

It's also helpful to add "Don't make up answers if you don't know." to your instruction block to make sure if the context is completely unrelated it doesn't make something up.

The only prompts that need this closed context formating are closed-context instructions. Normal questions/instructions do not!

I know it's a bit verbose and annoying, but after much trial and error, using these explicit delimiters helps the model understand where to find the responses and how to associate specific sources with it.

• BEGININPUT - denotes a new input block
• BEGINCONTEXT - denotes the block of context (metadata key/value pairs) to associate with the current input block
• ENDCONTEXT - denotes the end of the metadata block for the current input
• [text] - Insert whatever text you want for the input block, as many paragraphs as can fit in the context.
• ENDINPUT - denotes the end of the current input block
• [repeat as many input blocks in this format as you want]
• BEGININSTRUCTION - denotes the start of the list (or one) instruction(s) to respond to for all of the input blocks above.
• [instruction(s)]
• ENDINSTRUCTION - denotes the end of instruction set

It sometimes works without ENDINSTRUCTION, but by explicitly including that in the prompt, the model better understands that all of the instructions in the block should be responded to.

Here's a trivial, but important example to prove the point:

BEGININPUT
BEGINCONTEXT
date: 2021-01-01
url: https://web.site/123
ENDCONTEXT
In a shocking turn of events, blueberries are now green, but will be sticking with the same name.
ENDINPUT
BEGININSTRUCTION
What color are bluberries?  Source?
ENDINSTRUCTION

And the response:

Blueberries are now green.
Source:
date: 2021-01-01
url: https://web.site/123

The prompt itself should be wrapped in the vicuna1.1 template if you aren't using fastchat with the conv-template vicuna_v1.1 as described:

USER: BEGININPUT
BEGINCONTEXT
date: 2021-01-01
url: https://web.site/123
ENDCONTEXT
In a shocking turn of events, blueberries are now green, but will be sticking with the same name.
ENDINPUT
BEGININSTRUCTION
What color are bluberries?  Source?
ENDINSTRUCTION
 ASSISTANT:

Coding

You can ask for fairly complex coding instructions, e.g. (be sure to wrap with vicuna style prompt):

Create a python application with the following requirements:
- Asyncio FastAPI webserver
- ping endpoint that returns the current date in JSON format
- file upload endpoint, which calculates the file's sha256 checksum, and checks postgres to deduplicate

Or:

Write a multi-threaded TCP server in C that accepts a "GET [key]" input and "SET [key] [value]" input, and uses a binary tree to get and store the input values.

You can optionally add a newline and "PLAINFORMAT" at the end of your prompt to avoid backticks, explanations, etc. and just print the code, e.g.:

Write a websocket application in node.js.
PLAINFORMAT

Writing

Response:

ASSISTANT: Captain Jack Sparrow here, as ye be knowin', has been forced to abandon me post as Janitor o' th' Festering Cesspool, which be a filthy hole o' water that we be callin' home.

Ye may be thinkin' what could ha' driven me to leave me duties an' take me leave o' this sorry establishment? Well, ye'd be right in thinkin' so, for it be th' greed o' them what runs th' place that be drivin' me away. They've been fattenin' their pockets on me back while I've been slavin' me guts out cleanin' up their messes.

No more, me hearties! Me time o' servin' th' rich an' powerful be done, an' I'm takin' me leave o' this stinkin' hole forever! Me destiny lies elsewhere, an' it be time I pursued it. Ye may think ye've seen th' last o' me, but ye'd be wrong, for th' winds o' change be blowin', an' me ship be ready to set sail on th' high seas o' justice.

So, farewell ye scurvy dogs, ye who've made me life a living hell. I leave ye with me favorite saying: "ARRRGGGHHH, ye scurvy dogs!" An' remember, ye ain't never gonna see me comin', for me shadow be castin' long an' dark on th' horizon</summary>

Jokes

USER: Tell me a joke about bananas.
ASSISTANT: What did the banana say when it got hit by a bus? R.I.P.E.

Riddles (not great, but slightly better)

USER: What has a neck but no head?
ASSISTANT: A bottle.

Multi-character conversations

USER: Characters:
 - Yoda, the ever clever jedi master.
 - Homer Simpson, you know, the goofy yellow guy.
 - USER/Jon - don't generate any speech or actions on behalf of Jon

Rules:
 - be sure to use the manerisms and speaking style of the characters correctly
 - surround character actions with asterisks
 - always put quotes around words spoken by the characters
 - use a new line for each character's actions or speech
 - always prefix actions/speech with the character's name and colon
 - only generate text and actions on behalf of Yoda or Homer, and never anyone else

Conversation will revolve around the grapes, in a local cafe with delicious coffee.

Generate a single interaction between Yoda and Homer to start, with one sentence each.
ASSISTANT: Yoda: "Mmm, these grapes are quite delicious, Master Homer."

Homer: "Oh yeah, Yoda! They're the best grapes I've ever had!"
USER: *enters the cafe* Sorry I'm late guys!
ASSISTANT: Yoda: "No need to apologize, Jon. We were just enjoying these delightful grapes."

Homer: "Yeah, man! It's not every day you get to eat grapes with a real-life Jedi Master!"

*Yoda raises an eyebrow*
