Who this tier is for
Heavy is the right tier if you are doing volume research: a structured stack analysis program, regular receptor-pharmacology consults, multi-compound interaction reasoning, ongoing source critique on the bleeding edge of the literature.
You get the highest monthly quota (2000) and the largest Heavy budget (200). At those numbers most users have headroom to use Heavy mode liberally without thinking about the cap.
Heavy-tier subscribers also get priority routing during high-load periods, which means your queries skip the queue when the worker is at capacity. As Kodiac biolabs adds new modes (an experimental literature-search mode, deeper non-English literature coverage), Heavy-tier subscribers get first access.
If you are not sure whether to start at Lab or Heavy, start at Lab. You can upgrade mid-month and the new quota applies on next access. Most monthly research patterns fit comfortably inside the Lab budget.
Common questions
- How does monthly access work?
- One purchase covers one calendar month of access. Quotas reset on the first of each month UTC. Re-purchase the tier each month to continue, or switch tiers anytime.
- What happens if I run out?
- Once you hit your monthly quota the chat blocks new messages until the next month. Upgrade to a higher tier to lift the cap, or wait for the reset.
- Can I upgrade or downgrade?
- Yes. Buy a higher or lower tier at any time and the new quota applies on next access. Old tier access continues for the remainder of the month it was purchased for.
- Is the chat output research advice?
- No. Outputs are research reference material for in vitro and in vivo investigative work. Not medical advice. The compounds discussed are research use only and not for human or veterinary consumption.
