Summary

Melvin Vivas shares Fastino Labs' launch of GLiDE, a "thinking decision model" for decisions that need a lot of reasoning. He compares it to the decision model Jev and points out that, unlike Jev, GLiDE can be post-trained. The quoted launch post claims GLiDE beats Jev on the official Decision Index 0.2.1 scorer. The video has no usable speech; the transcript is only a captioning artifact.

Key points

• GLiDE is a new 'thinking decision model' from Fastino Labs (@fastinoAI), built for decisions that need a lot of reasoning.
• Main difference the creator points out: unlike Jev, GLiDE lets you post-train (customize) the model.
• On the official Decision Index 0.2.1 scorer, GLiDE scores 64.81, which Fastino says is 6.90 skill points ahead of Jev.
• Fastino says GLiDE beats Jev in all five evaluation areas, including one with an 11.5-point lead (the post is cut off before naming it).
• All benchmark numbers come from the vendor's launch post. Check them yourself before relying on them.
