	# Gemma 4 OpenCoder 40B-A8B BF16 v2

	Gemma 4 OpenCoder 40B-A8B v2 is a continued post-trained Gemma 4 coding
	model focused on agentic software engineering, long-context reasoning, and
	reliable tool use. It is designed for OpenCode workflows including repository
	navigation, implementation, editing, debugging, review, and sustained
	multi-file work.

	The checkpoint contains approximately 42.4B text parameters and activates
	approximately 8.1B text parameters per token. It retains Gemma 4's native
	262,144-token context window.

	This BF16 release is a self-contained checkpoint using the standard Gemma 4
	architecture. It does not require an adapter, external router, or auxiliary
	model.

	## Intended use

	- Agentic software engineering
	- OpenCode coding workflows
	- Long-context codebase navigation
	- Reasoning-enabled tool use
	- Multi-file implementation and editing
	- Debugging and code review

	Run with reasoning and automatic tool calling enabled, and preserve the
	checkpoint's included chat template.

	## Model format

	- Weight format: BF16 safetensors
	- Architecture: Gemma 4 Mixture-of-Experts
	- Total text parameters: approximately 42.4B
	- Active text parameters: approximately 8.1B per token
	- Maximum context: 262,144 tokens

	## vLLM

	```bash
	vllm serve LLMWildling/gemma-4-opencoder-40b-a8b-bf16-v2 \
	--tensor-parallel-size 2 \
	--reasoning-parser gemma4 \
	--tool-call-parser gemma4 \
	--enable-auto-tool-choice \
	--max-model-len 262144
	```

	Adjust tensor parallelism and context length for the available hardware. For
	OpenCode, select the served model and keep reasoning and tool calling enabled.
