data engineer here, offtopic, but am i the only guy tired of databricks shilling their tools as the end-all, be-all solutions for all things data engineering?
DBRX: A new open LLM

I'm still amazed that quantization works at all, coming out as a mild degradation in quality rather than radical dysfunction. Not that I've thought it through that much. Does quantization work with most neural networks?
> Does quantization work with most neural networks? Yes. It works pretty well for CNN-based vision models. Or rather, I'd claim it works even better: with post-training quantization you can make most models work with minimal precision loss entirely in int8 (fixed point), that is, computation is over int8/int32, no floating point at all, instead of weight-only approach discussed here. If you do QAT something down to 2…

> a 7B parameter model using float32s will almost certainly outperform a 7B model using float4s Q5 quantization performs almost on par with base models. Obviously there's some loss there, but this indicates that there's still a lot of compression that we're missing.

Re: DBRX: A new open LLM
#324That would be roughly 13.5M$ USD
I’m guessing that at this scale and cost, this model is not competitive and their ambition is to scale to much larger models. In the meantime , they learned a lot and gain PR from open-sourcing

#326" Get Started with DBRX on Databricks
If you’re looking to start working with DBRX right away, it’s easy to do so with the Databricks Mosaic AI Foundation Model APIs. You can quickly get started with our pay-as-you-go pricing and query the model from our AI Playground chat interface. For production applications, we offer a provisioned throughput option to provide performance guarantees, support for finetuned models, and additional security and compliance. To privately host DBRX, you can download the model from the Databricks Marketplace and deploy the model on Model Serving."

"The weights of the base model (DBRX Base) and the finetuned model (DBRX Instruct) are available on Hugging Face under an open license."

> less triggering to an "all y-axes must have zero" guy Ever read 'How to Lie with Statistics'? This is an example of exaggerating a smaller difference to make it look more significant. Dismissing it as just being 'triggered' is a bad idea.
In this case I would called it triggered (for lack of a better word), since, as I described earlier, a chart plotting "difference from 100%" would look exactly the same, and satisfy the zero-bound requirement, while not being any more or less dishonest

#329Model card for base: https://huggingface.co/databricks/dbrx-base > The model requires ~264GB of RAM I'm wondering when everyone will transition from tracking parameter count vs evaluation metric to (total gpu RAM + total CPU RAM) vs evaluation metric. For example, a 7B parameter model using float32s will almost certainly outperform a 7B model using float4s. Additionally, all the examples of quantizing recently releas…
Looks like someone has got DBRX running on an M2 Ultra already: https://x.com/awnihannun/status/1773024954667184196?s=20
Now this model is ~134B right? It could be bog slow but on the other hand its a MoE so there might be a chance it could have satisfactory results.
Re: DBRX: A new open LLM
#330Just curious, what business benefit will Databricks get by spending potentially millions of dollars on an open LLM?
An increased valuation at IPO later this year.
But really, I prefer to have as many players as possible in the field of _open_ models available.
