Summary from the TLDR AI newsletter

Minimax has released two new variants of its M2.5 language model. While it is supposed to be open source, the weights and code have yet to be posted, nor has the company indicated the exact license type or terms. The models drop the cost of inference by as much as 95% while delivering performance that rivals top-tier models. They can be accessed through MiniMax's API and those of partners.
