Definition
jev-1.13.0 is the model behind both aliases. Its model card lists $42 per Btok input with free output, rate limits of 250,000 tokens per second and 1,200 requests per minute, and a 64k context split as 32k for state plus the longest question.
It is also the version the jaggedness page tracks: literal reading, unreliable counting, dates as text, indirection, context rot, and structural invariants that do not hold. Many of those are expected to be fixed in later versions.
