PhoneBuddy-0.8B
PhoneBuddy-0.8B is the small PhoneBuddy Real+Mock reinforcement-learning checkpoint.
Project page: https://phonebuddyai.github.io/
GitHub: https://github.com/PhoneBuddyAI/phonebuddy
Model Details
- Model family: Qwen3.5 VL style checkpoint
model_type:qwen3_5- Processor:
Qwen3VLProcessor - Checkpoint role: small Real+Mock RL checkpoint
- Tool-call format: Qwen-style XML as defined in
chat_template.jinja
The model card and repository are initially published as private for validation.
Tool-Call Format
PhoneBuddy-0.8B follows the Qwen-style XML tool-call format defined by the bundled chat_template.jinja, for example:
<tool_call>
<function=example_function_name>
<parameter=example_parameter_1>
value_1
</parameter>
</function>
</tool_call>
Use the tokenizer or processor chat template from this repository when constructing prompts with tools.
Loading Environment
These checkpoints use Qwen3.5 VL style model metadata:
model_type:qwen3_5- Architecture:
Qwen3_5ForConditionalGeneration - Processor:
Qwen3VLProcessor - Tokenizer metadata:
TokenizersBackend
Use the matching Qwen3.5 VL / PhoneBuddy training or inference environment that registers these classes. In a generic public Transformers environment, compatibility depends on whether that build includes qwen3_5 and the tokenizer backend used by this checkpoint.
A minimal processor load can be tested with:
from transformers import AutoProcessor
repo_id = "PhoneBuddyAI/PhoneBuddy-0.8B"
processor = AutoProcessor.from_pretrained(repo_id, trust_remote_code=False)
Full config, tokenizer, and model loading should be done in an environment that supports the classes above. For example, public transformers==4.57.6 does not register model_type=qwen3_5, and AutoTokenizer does not import TokenizersBackend; in that environment those failures indicate version/class compatibility, not missing checkpoint files.
Intended Use
PhoneBuddy is designed for research on phone agents, multimodal tool use, and visual action reasoning. This smaller checkpoint is intended for lower-cost experiments and comparisons.
