I like that v4 flash is so fast! I run it on both FireWorks.ai in the US and bought some tokens directly from DeepSeek as an experiment. I only work on Open Source projects, so I don’t have to worry about my work being used to train models - I welcome AI’s being trained on my open content books and code (but not my conventionally published books: I am a party to the copyright suit against Anthropic).

Yea, Flash is quite fast, though looking at model data on Open Router some of the other models are quite fast (Muse Spark, Grok, etc). I’m sure all these models have been trained on my conventionally published books as well, but I don’t care.
