zeromodels/qwen2-7b-instruct

Qwen2 is Alibaba's decoder-only transformer family: grouped-query attention with q/k/v bias, SwiGLU MLPs, RMSNorm, and rotary positions, in dense 0.5B-72B sizes (plus the Qwen2-57B-A14B mixture-of-experts), as base and instruct variants.

For more details on the model, please see the upstream model card.

Pure-Keras 3 conversion of Qwen/Qwen2-7B-Instruct for zeromodels. One implementation runs unmodified on TensorFlow / Torch / JAX.

This is an instruct (chat-tuned) checkpoint; load Qwen2Tokenizer so the chat template is applied.

Quick start

python

import os
os.environ["KERAS_BACKEND"] = "torch"  # or "jax" / "tensorflow"

from zeromodels.models.qwen2 import Qwen2TextGenerate, Qwen2Tokenizer

model = Qwen2TextGenerate.from_weights("zeromodels/qwen2-7b-instruct")
tokenizer = Qwen2Tokenizer.from_weights("zeromodels/qwen2-7b-instruct")

inputs = tokenizer([
    {"role": "user", "content": "Explain rotary embeddings in one sentence."}
])
outputs = model.generate(**inputs, max_new_tokens=64)
print(tokenizer.decode(outputs[0]))

Load any Qwen2 variant the same way with from_weights("zeromodels/<variant>"):

Variant	Hub	Type
`qwen2-0.5b`	`zeromodels/qwen2-0.5b`	base
`qwen2-0.5b-instruct`	`zeromodels/qwen2-0.5b-instruct`	instruct
`qwen2-1.5b`	`zeromodels/qwen2-1.5b`	base
`qwen2-1.5b-instruct`	`zeromodels/qwen2-1.5b-instruct`	instruct
`qwen2-7b`	`zeromodels/qwen2-7b`	base
`qwen2-7b-instruct`	`zeromodels/qwen2-7b-instruct`	instruct
`qwen2-72b`	`zeromodels/qwen2-72b`	base
`qwen2-72b-instruct`	`zeromodels/qwen2-72b-instruct`	instruct
`qwen2-57b-a14b`	`zeromodels/qwen2-57b-a14b`	MoE base
`qwen2-57b-a14b-instruct`	`zeromodels/qwen2-57b-a14b-instruct`	MoE instruct
`qwen1.5-moe-a2.7b`	`zeromodels/qwen1.5-moe-a2.7b`	MoE base
`qwen1.5-moe-a2.7b-chat`	`zeromodels/qwen1.5-moe-a2.7b-chat`	MoE chat

Tips

Set KERAS_BACKEND before importing Keras / zeromodels.
Prefer Qwen2Tokenizer.from_weights(...) so the chat template matches.
Larger checkpoints: try load_dtype="bfloat16" or quantization="int8".
See Loading Weights and the Qwen2 docs.
Community / upstream safetensors still work via the hf: prefix, e.g. Qwen2TextGenerate.from_weights("hf:Qwen/Qwen2-7B-Instruct").

Special Thanks

A huge thank you to the Qwen team at Alibaba for creating and releasing these models.
