Libraries

How to use LLMWildling/gpt-oss-200b-goblin with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="LLMWildling/gpt-oss-200b-goblin")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("LLMWildling/gpt-oss-200b-goblin")
model = AutoModelForCausalLM.from_pretrained("LLMWildling/gpt-oss-200b-goblin")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

gpt-oss-200b-goblin

gpt-oss-200b-goblin is an agentic coding model derived from GPT-OSS 120B.

Goblin expands the GPT-OSS 120B base with additional specialist MoE capacity for coding-agent workflows, repository work, SWE-style tasks, tool-using automation, and math-assisted reasoning.

This release continues the Goomba line with more SWE and sequential-agentic specialist capacity. It was trained on just two GPUs.

Overview

Base model: openai/gpt-oss-120b
Approx total parameters: 201B
Approx active parameters: 16.5B per token at top-k=16
Total expert rows: 224
Added specialist experts: 96
Format: MXFP4
Out-of-box active experts: top-k=16
Intended use: agentic coding, SWE-style workflows, repository exploration, tool-using automation, raw SWE coding, math-assisted coding
Status: research preview

Recommended vLLM

This model was primarily tested with vLLM using the GPT-OSS reasoning parser and OpenAI tool-call parser.

vllm serve /path/to/model \
  --served-model-name vllm/doobee \
  --tensor-parallel-size 2 \
  --max-model-len 60000 \
  --gpu-memory-utilization 0.88 \
  --enforce-eager \
  --trust-remote-code \
  --reasoning-parser openai_gptoss \
  --tool-call-parser openai \
  --enable-auto-tool-choice

Recommended parameters:

num_experts_per_tok=16 is already set in config.json
tensor-parallel-size=2
max-model-len=60000
gpu-memory-utilization=0.88
reasoning-parser=openai_gptoss
tool-call-parser=openai
enable-auto-tool-choice

The config ships with both num_experts_per_tok=16 and experts_per_token=16, so runtimes that respect the model config should use top-k 16 automatically. If your runtime overrides or ignores those fields, pass this explicitly:

--hf-overrides '{"num_experts_per_tok": 16}'

Tool Calling

Goblin was primarily tested as an agentic coding model. Basic OpenAI-compatible tool calling is expected to work best with the vLLM GPT-OSS reasoning parser and OpenAI tool-call parser enabled.

Suggested temperatures:

0.3 for steady coding-agent work
0.5 for broader agentic exploration

Recommended range: 0.3-0.5.

For repository exploration tasks, use an agent prompt that asks the model to inspect subdirectories, identify entry points, and summarize the project structure rather than stopping after a single directory listing.

License

Replace the placeholder license: other metadata with the actual license you want to publish under after confirming compatibility with the base model and your added weights.
