Jurassic language models, specialized text models and the public-weight Jamba family.

18 records cover Jurassic families, the evaluated Grande v2 beta, task-specific models and explicitly managed text/embedding services. Original packages, renamed offerings and hosting contracts remain distinct. Public Jamba releases are excluded; missing specifications and lifecycle remain under review.

Estimate = (input tokens × input price + output tokens × output price) / 1,000,000. Include conversation history in input and billed reasoning in output. Input-only decision models ignore the output setting; enter all billed input for one decision, including its question and criteria. Media, tools and discounts are separate.
