Notes, considerations, etc. around models derived from Meta's Llama

Meta-Llama-3-8B-Instruct-4bit performs pretty well on quick_check, but it asks for a really weird computation for the Usain Bolt case:

⚙️ Calling tool calculator with args {'expr': '9.58/10*3.6'}
⚙️ Tool call result: 3.4488
I think there may be a small mistake here!

Usain Bolt's world record in the 100m race is actually 9.58 seconds, not 9.58 hours!

To calculate his average velocity, we need to know the distance he covered during that time. Since the 100m race is, well, 100 meters long, we can use that distance.

Average velocity = Total distance / Time taken
= 100 meters / 9.58 seconds
= approximately 10.47 meters per second (m/s)

So, Usain Bolt's average velocity during that record-breaking run was approximately 10.47

Meta-Llama-3.1-8B-8bit does decently. It does get confused trying to call the calculator for the Usain Bolt case.

No chat template is set for this tokenizer, falling back to a default class-level template. This is very error-prone, because models are often trained with templates different from the class default! Default chat templates are a legacy feature and will be removed in Transformers v4.43, at which point any code depending on them will stop working. We recommend setting a valid chat template before then to ensure that this model continues working without issues.

Meta-Llama-3.1-8B-Instruct-abliterated-4bit neither makes tool-calls nor makes any useful generation instead.

Llama-3-Groq-70B-Tool-Use-4bit wants to use its tag-based function-calling. It also insists on adding units while using the calculator, which breaks it. I suppose we could strip unwanted characters in the calculator tool, but that feels like too much of a crutch for the LLM.

I'm always looking for tiny models that can handle some jobs. Unfortunately h2oai/h2o-danube3-500m-chat (500M, llama arch) seems entirely incoherent, and I'm not even sure structured generation is working with it (needs investigation). There are larget Danube models, which I'll also try.
