The Zen models endpoint currently also lists `trinity-large-preview-free`, but models.dev marks it deprecated, so it is not recommended here.

 ## Choosing Between Providers
 
 ### Use OpenCode Zen when:
+
 - You want the most tested and reliable free models
-- You prefer `nemotron-3-super-free` as the default with ~262K context window
+- You prefer `minimax-m2.5-free` as the default with a 204,800 token context window
 - You need a simple, curated list of models
 
 ### Use Kilo Gateway when:
+
 - You want access to GLM-5 (currently free, limited time)
 - You need larger context windows (up to 256,000 tokens)
 - You want more free model options
