Key Components

GenerationPipeline

The GenerationPipeline class provides a streamlined interface for text generation using pre-trained language models within the JAX framework.

import easydel as ed
from transformers import AutoTokenizer

model, params = ed.AutoEasyDeLModelForCausalLM.from_pretrained(...)
tokenizer = AutoTokenizer.from_pretrained(...)

pipeline = ed.GenerationPipeline(model=model, params=params, tokenizer=tokenizer)

ApiEngine

ApiEngine is a Serve API Engine for production purposes, providing a stable and efficient API.

import easydel as ed

pipeline = ed.ChatPipeline(...)
engine = ed.ApiEngine(pipeline=pipeline, hostname="0.0.0.0", port=11550)
engine.fire()

EasyDeLState

EasyDeLState acts as a comprehensive container for your EasyDeL model, including training progress, model parameters, and optimizer information.

from easydel import EasyDeLState

state = EasyDeLState.from_pretrained(
    pretrained_model_name_or_path="model_name",
    dtype=jnp.bfloat16,
    param_dtype=jnp.bfloat16,
    sharding_axis_dims=(1, -1, 1, 1)
)

Training Examples

Supervised Fine-Tuning

from easydel import SFTTrainer, TrainArguments

trainer = SFTTrainer(
    arguments=train_arguments,
    train_dataset=train_dataset,
    eval_dataset=eval_dataset,
    tokenizer=tokenizer,
    formatting_func=prompter,
    packing=True,
    num_of_sequences=max_length,
)

output = trainer.train(flax.core.FrozenDict({"params": params}))

DPO Fine-tuning

from easydel import DPOTrainer

dpo_trainer = DPOTrainer(
    model_state=state,
    ref_model_state=ref_state,
    beta=0.1,
    train_dataset=train_dataset,
    eval_dataset=eval_dataset,
    tokenizer=tokenizer,
    arguments=arguments,
    max_length=max_length,
    max_target_length=max_target_length,
    max_prompt_length=max_prompt_length,
)

output = dpo_trainer.train()
