Coscientist: how many tokens per task, and what does it cost?
Coscientist publishes no per-task cost or token figure in the AgentBurn index. AgentBurn snapshot 2026-10-27. Every figure carries a provenance label: source-backed, derived, or left empty when no public basis exists.
What it is. LLM agent that designs, codes and runs real chemistry experiments
Coscientist combines web search, code execution and robotic lab APIs so an LLM can plan a synthesis, write the control code and actually run it on automated hardware. In its Nature paper it optimised Suzuki and Sonogashira couplings and discovered a new reaction pathway, working end-to-end from a natural-language brief.

Where the tokens go
This is the per-task split AgentBurn records for Coscientist, step by step.
| Step | What happens | Share of tokens | Tool calls |
|---|---|---|---|
| Parse objective | Turns the chemistry goal into a plan and constraints | 8% | 4 |
| Search protocols | Reads literature and vendor docs for procedures | 20% | 18 |
| Write control code | Generates and tests the Python that drives the robot | 26% | 22 |
| Execute runs | Runs synthesis cycles and reads instrument output | 30% | 34 |
| Analyse and iterate | Interprets spectra and adjusts the next run | 16% | 17 |
What each number is based on
AgentBurn labels every field. Source-backed means the cited page states the figure; derived means a formula on this page produced it; not published means no public basis exists and the field is left empty rather than estimated.
| Field | Basis | Note |
|---|---|---|
| tokensPerTask | Not published | No usable public source for per-task tokens. |
| costPerTaskUsd | Not published | No usable public source for per-task cost. |
| successRatePct | Not published | No public task success rate. |
| runsPerDay | Not published | No public run volume. |
Frequently asked
How many tokens does Coscientist use per task?
No public tokens-per-task figure exists for Coscientist; AgentBurn leaves the field empty rather than estimating it.
What does Coscientist cost per task?
No public per-task cost exists for Coscientist, so it is recorded as not published.
Is this a vendor list price?
No. It is a per-task figure from a cited source, not a rate card; the two are not comparable.
