What is the fastest model in Ollama?

So, if you’re diving into the world of Ollama and wondering which model doesn’t just get the job done but gets it done fast, let me tell you about the wizardlm2:7b. This little powerhouse is seriously impressive—it’s the fastest model Ollama has to offer, and it holds its own against models that are 10 times larger. Yeah, you read that right. It’s like comparing a zippy sports car to a lumbering freight truck. Sure, the truck might haul more, but the sports car? It’s all about efficiency and speed.

Let me break it down: when I first started playing with large language models, speed wasn’t even on my radar. I was all about accuracy and capability—until I hit a few deadlines where speed was non-negotiable. That’s when I stumbled on wizardlm2:7b. It’s perfect for those moments when you don’t want to wait around for results but still need solid output.

For instance, I was working on generating summaries for a content batch recently, and the 7b model cranked through it faster than I could organize my coffee table (which, trust me, is a task in itself). Plus, the quality? Surprisingly sharp for something so quick.

When Should You Use wizardlm2:8x22b?

Now, if you’re looking for the ultimate model—like the best Ollama has to offer—it’s hands-down the wizardlm2:8x22b. This is the model you call in for the heavy-lifting, high-stakes, complex stuff. Microsoft even gave it the crown in their internal evaluations on tasks that make lesser models throw in the towel. It’s not the fastest, sure, but when it comes to nuance and depth, it’s untouchable.

Here’s a quick anecdote: I was tackling a super detailed project analyzing sentiment trends across thousands of customer reviews. Normally, I’d have to babysit the process, tweaking outputs and making sense of garbled predictions. But with the 8x22b, I barely had to lift a finger—it just got it. Things like subtle sarcasm, cultural nuances, or multi-layered prompts that trip up other models? This one handled it with ease. I was almost annoyed at how little work I had to do!

Practical Tips for Choosing Between the Two

Here’s a quick guide I’ve figured out from experience:

  • Choose wizardlm2:7b if:
    • You’re working on tasks with tight deadlines.
    • The task requires speed but doesn’t need extreme depth.
    • You’ve got limited computational resources (it’s lighter on that front too).
  • Go with wizardlm2:8x22b if:
    • The project involves highly complex or nuanced work.
    • You’re okay with trading a bit of time for stellar results.
    • Accuracy and advanced understanding matter more than speed.

To put it in relatable terms, think of these models like a Swiss Army knife (7b) versus a deluxe, hyper-specialized toolkit (8x22b). Both are brilliant in their own way, but the best choice depends on what you’re trying to build.
