Nice work! This is like a much better version of Ancient Earth[0], which I made ~10 years ago using GPlates[1]. I like your approach of rendering the map itself from data, which makes it continuous, rather than just wrapping map textures around a globe.

Thanks to Meta for their work on safety, particularly Llama Guard. Llama Guard 3 adds defamation, elections, and code interpreter abuse as detection categories.

Having run many red teams recently as I build out promptfoo's red teaming featureset [0], I've noticed the Llama models punch above their weight in terms of accuracy when it comes to safety. People hate excessive guardrails and Llama seems to thread the needle.

Very bullish on open source.

It's exceptionally strong. In LMSys Chatbot Arena, the 27B version scores above LLama-3-70B, at the level of OpenAI GPT-4 and Claude-3 Sonnet!

If anyone is interested in evaling Gemma locally, this can be done pretty easily using ollama[0] and promptfoo[1] with the following config:

  prompts:
    - 'Answer this coding problem in Python: {{ask}}'

  providers:
    - ollama:chat:gemma2:9b
    - ollama:chat:llama3:8b

  tests:
    - vars:
        ask: function to find the nth fibonacci number
    - vars:
        ask: calculate pi to the nth digit
    - # ...

One small thing I've always appreciated about Gemma is that it doesn't include a "Sure, I can help you" preamble. It just gets right into the code, and follows it with an explanation. The training seems to emphasize response structure and ease of comprehension.

Also, best to run evals that don't rely on rote memorization of public code... so please substitute with your personal tests :)

do we really need more yaml?

This is insane to me.

Care to explain why you think so?
