Cadence / ChipStack
Chip-design AI with documented private ChipStack RFT derivatives and a separately identified managed agent workflow.
Partial documented coverage. Exact current checkpoint inventory, private inference contracts and worldwide completeness remain unresolved.
Start with the job your model needs to do. Then narrow by capabilities, provider and price.
Compare every model with the same request.
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.
