I've used Gemma for reviewing and categorizing my writing online over several years (~5 million words across a forum for an OSS project I work on, HN, reddit, etc.), experimenting with training LoRAs (again, on my own writing, since I don't have to worry about ethically sourcing the data if it's all mine), and I'm currently using it to perform web searches and extract data about a specific type of business. It's plenty smart to use a web search MCP to find all the businesses of the right type in a given city, read their website, extract business address, phone number, etc. among other things, and de-dupe and cross-check other sources.

I found Gemma 4 to be better, or at least more nuanced, than Gemini 2.5 Flash. And, the new Gemini 3.5 Flash is very good but is unrealistically expensive (ten times more expensive than DeepSeek or MiMo). So, since I don't need extremely fast performance, a self-hosted Gemma 4 wins for a bunch of stuff.

I've also found Qwen 3.6 27B to be shockingly good at finding security bugs for its size. It beats several larger models, and is close to Gemini Pro 3.1 (but Gemini 3.5 Flash surprisingly beats it soundly). Since it only costs electricity, and my electricity is cheap and 100% renewable, I can use it more broadly than I might otherwise use a hosted model.

All that said, the smart money is still on buying the subsidized tokens from the providers that offer them, rather than buying the hardware needed to run models that are 30+GB in size, as all of the ones I've been using regularly are (8-bit quantization, as they get a little dumber for every bit you drop below that). A $100 subscription to Claude or Codex currently provides access to the best models at a heavily discounted rate. And, DeepSeek/MiMo are extremely cheap, one or more orders of magnitude cheaper than the top models from Anthropic or OpenAI, if you need an API for automated usage. I spent about $4000 on my two inference machines (a Strix Halo with 128GB unified RAM, and a new desktop build based around two cheap old 32GB AMD data center GPUs), which buys a lot of tokens for tiny models like this...probably a couple/few years worth. But, I like tinkering, so having an excuse to play with hardware is its own reward. If it happens to pay me back some of that money, that's a bonus.

Of course, as the major providers decide they need to ring the cash register and stop burning money on subsidized tokens, that math may change, and I may find I'm grateful to have already bought this stuff before the RAM prices made everything 2-3x more expensive.

But, I think if you're not interested in learning about the technology and doing your own training experiments and such, you should probably not try to run stuff locally most of the time.
