π Thank You for 150,000+ Downloads
You made this the most downloaded Gemma 4 E4B fine-tune in the world.
We were the first to train Gemma 4 at the weights β 7 days after Google released it, 3 months before anyone else published a guide. And you showed up. 140,000+ of you. Zero community issues. That means everything.
v2 Is Here β 10x the Training Data
We heard you. We shipped harder.
π gemma-4-E4B-Agentic-Sol-Fable-Reasoning-GeminiCLI-mlx-4bit
Same tool calling. Same OpenHarness. Same OpenClaw. Same Hermes support. Same no-adapter-needed experience. We simply 10x'd the update.
| This model (v1) | v2 | |
|---|---|---|
| Training examples | 2,163 | 22,389 |
| Data | Opus reasoning | Opus + Sol coding + FABLE.5 reasoning |
| Production coding | Basic | 17,939 xhigh reasoning traces |
<think> depth | β | β + 4,450 FABLE.5 deep thinking traces |
| Tool calling | β | β |
| Adapter needed? | No | No |
This model (v1) is still fully supported and will stay up. If you're already using it in production, it works great. v2 is for when you want the next level.
We will continue to innovate and simply do what others can't.

Quickstart
pip install mlx-lm mlx-vlm
from mlx_lm import load, generate
# No adapter_path needed β reasoning is in the weights
model, tokenizer = load("deadbydawn101/gemma-4-E4B-Agentic-Opus-Reasoning-GeminiCLI-mlx-4bit")
messages = [{"role": "user", "content": "Explain why RSA encryption is hard to break."}]
prompt = tokenizer.apply_chat_template(messages, add_generation_prompt=True, tokenize=False)
response = generate(model, tokenizer, prompt=prompt, max_tokens=1024, verbose=True)
# β Will produce <think>...</think> followed by structured answer
CLI
mlx_lm.generate \
--model deadbydawn101/gemma-4-E4B-Agentic-Opus-Reasoning-GeminiCLI-mlx-4bit \
--prompt "Debug this Python code: def fib(n): return fib(n-1) + fib(n-2)" \
--max-tokens 1024
π§© OpenHarness + OpenClaw + Hermes Agent
This model is built to sit inside a real agent stack, not just a chat box.
We support:
- OpenHarness for agent harness/runtime, skills, hooks, tool loops, and multi-agent flows
- OpenClaw for orchestration, sessions, reminders, and cross-agent routing
- Hermes agent skill for terminal-native coding posture, short planning, aggressive tool use, and repo-aware execution
Why this combo matters
| Layer | Role |
|---|---|
| Gemma 4 E4B Opus Reasoning + Claude Code | reasoning + tool-use behavior baked into the weights |
| Gemini CLI | coding agent + tool orchestration |
| OpenHarness | harness runtime, tool loop, swarm, hooks, memory |
| OpenClaw | orchestration, sessions, skills, messaging |
| Hermes skill | agent behavior for concise, terminal-first execution |
OpenHarness quickstart
pip install openharness
mlx_lm.server \
--model deadbydawn101/gemma-4-E4B-Agentic-Opus-Reasoning-GeminiCLI-mlx-4bit \
--port 8080
oh --model http://localhost:8080/v1 \
--skill hermes-agent \
-p "Review this repo, find bugs, patch them, and summarize the result"
OpenClaw skill stack
Inside OpenClaw, pair this model with:
openharnessskill β run/configureohhermes-agentskill β shape coding-agent behavior
That gives you a fully local Apple Silicon agent lane with:
- baked-in reasoning
- native tool calling
- Gemini CLI integration
- OpenHarness runtime support
- OpenClaw orchestration
π» Gemini CLI β Coding Agent + Tool Orchestration
We use RavenX AI's Gemini CLI fork as the coding agent and tool orchestration layer on top of these models. This is what makes the tool-calling capability real in production.
Gemini CLI gives you a full agentic loop in the terminal β Google Search grounding, file read/write, shell execution, web fetching, and MCP server support β all wired to a 1M token context window.
# Install
npm install -g @google/gemini-cli
# Run as a coding agent against this model (via local mlx_lm server)
mlx_lm.server --model deadbydawn101/gemma-4-E4B-Agentic-Opus-Reasoning-GeminiCLI-mlx-4bit --port 8080 &

What Gemini CLI + these models unlock together
| Capability | How |
|---|---|
| Code generation | Gemini CLI reads your codebase, model reasons with <think> tags |
| Tool calling | Native <|tool> tokens β Gemini CLI executes shell/file/web tools |
| Long context | 1M ctx in CLI + TurboQuant 4.6x KV compression = very long sessions |
| MCP servers | Connect any MCP server β databases, APIs, custom tools |
| Search grounding | Google Search built in β model gets live data |
# Real example: code review with tool calling enabled
gemini --baseUrl http://localhost:8080 \
"Review all Python files in ./src, find potential bugs, and suggest fixes"
# Gemini CLI will: read files β call tools β model reasons β produce structured output
β DeadByDawn101/gemini-cli on GitHub β Apache 2.0, free tier, MCP-compatible
β‘ TurboQuant-MLX β 4.6x KV Cache Compression
Pair with TurboQuant-MLX to compress the KV cache and run 4.6x longer reasoning chains at the same memory:
from turboquant_mlx.mlx_kvcache import TurboQuantKVCache
import mlx_lm.models.cache as cache_module
cache_module.make_prompt_cache = lambda model, **kw: [
TurboQuantKVCache() for _ in range(len(model.layers))
]
from mlx_lm import load, generate
model, tokenizer = load("deadbydawn101/gemma-4-E4B-Agentic-Opus-Reasoning-GeminiCLI-mlx-4bit")
# Long reasoning chains now fit in the same RAM budget
