5 years is normal-ish depreciation time frame. I know they are gaming GPUs, but the RTX 3090 came out ~ 4.5 years before the RTX 5090. The 5090 has double the performance and 1/3 more memory. The 3090 is still a useful card even after 5 years.
The instruct models are available on Ollama (e.g. `ollama run ministral-3:8b`), however the reasoning models still are a wip. I was trying to get them to work last night and it works for single turn, but is still very flakey w/ multi-turn.
The default ones on Ollama are MXFP4 for the feed forward network and use BF16 for the attention weights. The default weights for llama.cpp quantize those tensors as q8_0 which is why llama.cpp can eek out a little bit more performance at the cost of worse output. If you are using this for coding, you definitely want better output.
You can use the command `ollama show -v gpt-oss:120b` to see the datatype of each tensor.
We uploaded gemma3:270m-it-q8_0 and gemma3:270m-it-fp16 late last night which have better results. The q4_0 is the QAT model, but we're still looking at it as there are some issues.
I worked on the text portion of gemma3 (as well as gemma2) for the Ollama engine, and worked directly with the Gemma team at Google on the implementation. I didn't base the implementation off of the llama.cpp implementation which was done in parallel. We did our implementation in golang, and llama.cpp did theirs in C++. There was no "copy-and-pasting" as you are implying, although I do think collaborating together on these new models would help us get them out the door faster. I am really appreciative of Georgi catching a few things we got wrong in our implementation.
