...Mixtral 8x7B
🟢 Smarter AI 🟢
Mixtral 8x7B on Ollama is a powerful, free, and genuinely multilingual model suitable for AI agents in workflow automation, but it has significant hardware requirements and may lack native function-calling capabilities in the 8x7B base model.
Capabilities for Workflow Automation
Performance: Mixtral 8x7B performs exceptionally well, matching or exceeding models like GPT-3.5 and Llama 2 70B on various benchmarks, while offering faster inference speeds due to its Sparse Mixture of Experts (SMoE) architecture.
Multilingual Support: It was trained with multilingual data and is highly proficient in languages including English, French, Italian, German, and Spanish, making it versatile for global workflow automation tasks.
Agentic Use Cases: It excels in text summarization, classification, generation, and code generation—all key tasks for AI agents. It can be integrated with tools like LlamaIndex to build local, private AI assistants and perform RAG (Retrieval-Augmented Generation).
Open-Access & Free: The model weights are openly available under the Apache 2.0 license, meaning it's free to download and use for commercial activities. Ollama provides a free, open-source framework for running it locally with a single command.
Key Considerations and Limitations
High Hardware Requirements: This is the primary limitation. To run unquantized Mixtral 8x7B smoothly, you typically need around 48GB of RAM or VRAM. While quantization (running a compressed version) can reduce this, it may require multiple high-end consumer GPUs (e.g., two RTX 3090s with 24GB VRAM each) to run effectively without quality degradation.
Performance on Ollama: While Ollama makes running the model easy, some users have noted that the model performance on Ollama can be worse compared to platforms like vLLM for the same unquantized configuration, potentially due to underlying optimizations or on-the-fly quantization by Ollama to manage memory.
Function Calling: The base Mixtral 8x7B model does not natively support tool calling (essential for complex AI agents that need to interact with external systems). However, the newer Mixtral 8x22B model and specific fine-tunes like Nous Hermes 2 Mixtral 8x7B (available on the Ollama library) are capable of function calling.
Fine-tuning is Key: For specific, complex workflow automation tasks, fine-tuning the base model with domain-specific data will likely be necessary to achieve the best results.
