Model Overview

Mistral is a set of large language models published by the Mistral AI team. Both pretrained and instruction tuned models are available with 7 billion parameters. See the model card below for benchmarks, data sources, and intended use cases.

Both weights and Keras model code is released under the Apache 2 License.

Installation

Keras and KerasHub can be installed with:

pip install -U -q keras-hub
pip install -U -q keras

Jax, TensorFlow, and Torch come preinstalled in Kaggle Notebooks. For instructions on installing them in another environment see the Keras Getting Started page.

Presets

The following model checkpoints are provided by the Keras team. Full code examples for each are available below.

Preset name	Parameters	Description
`mistral_7b_en`	7.24B	7B base model
`mistral_instruct_7b_en`	7.24B	7B instruction-tuned model
`mistral_0.2_instruct_7b_en`	7.24B	7B instruction-tuned model version 0.2

Prompts

Mistral "instruct" models are instruction tuned on turn by turn conversations and should be prompted with examples that precisely match the training data. Specifically, you must alternate user and assistant turns that begin and end with special tokens. See the following for an example:

python

prompt = """[INST] Hello! [/INST] Hello! How are you? [INST] I'm great. Could you help me with a task? [/INST]
"""

Base models (without instruct in the name) have no specific prompting structure, and should usually be fine-tuned for a specific task.

Example Usage

python

import keras
import keras_hub
import numpy as np

Use generate() to do text generation.

python

mistral_lm = keras_hub.models.MistralCausalLM.from_preset("mistral_0.3_7b_en")
mistral_lm.generate("[INST] What is Keras? [/INST]", max_length=500)

# Generate with batched prompts.
mistral_lm.generate(["[INST] What is Keras? [/INST]", "[INST] Give me your best brownie recipe. [/INST]"], max_length=500)

Compile the generate() function with a custom sampler.

python

mistral_lm = keras_hub.models.MistralCausalLM.from_preset("mistral_0.3_7b_en")
mistral_lm.compile(sampler="greedy")
mistral_lm.generate("I want to say", max_length=30)

mistral_lm.compile(sampler=keras_hub.samplers.BeamSampler(num_beams=2))
mistral_lm.generate("I want to say", max_length=30)

Use generate() without preprocessing.

python

prompt = {
    # `1` maps to the start token followed by "I want to say".
    "token_ids": np.array([[1, 315, 947, 298, 1315, 0, 0, 0, 0, 0]] * 2),
    # Use `"padding_mask"` to indicate values that should not be overridden.
    "padding_mask": np.array([[1, 1, 1, 1, 1, 0, 0, 0, 0, 0]] * 2),
}

mistral_lm = keras_hub.models.MistralCausalLM.from_preset(
    "mistral_0.3_7b_en",
    preprocessor=None,
    dtype="bfloat16"
)
mistral_lm.generate(prompt)

Call fit() on a single batch.

python

features = ["The quick brown fox jumped.", "I forgot my homework."]
mistral_lm = keras_hub.models.MistralCausalLM.from_preset("mistral_0.3_7b_en")
mistral_lm.fit(x=features, batch_size=2)

Call fit() without preprocessing.

python

x = {
    "token_ids": np.array([[1, 315, 947, 298, 1315, 369, 315, 837, 0, 0]] * 2),
    "padding_mask": np.array([[1, 1, 1, 1, 1, 1, 1, 1, 0, 0]] * 2),
}
y = np.array([[315, 947, 298, 1315, 369, 315, 837, 0, 0, 0]] * 2)
sw = np.array([[1, 1, 1, 1, 1, 1, 1, 0, 0, 0]] * 2)

mistral_lm = keras_hub.models.MistralCausalLM.from_preset(
    "mistral_0.3_7b_en",
    preprocessor=None,
    dtype="bfloat16"
)
mistral_lm.fit(x=x, y=y, sample_weight=sw, batch_size=2)
