Know who promised what, what is still open, and who got the work

Conversation Cues (Cue for short) reads a line from a meeting, call or chat, together with the turns before it, and scores three cues: did the speaker make a commitment, ask an open question, or hand work to someone else? It is a 32M-parameter model. Use the API, or run the open model yourself.

cues lists the cues the line carries. Behind it, each cue has a score from 0 to 1 and a threshold, fitted on human-labelled meetings; send thresholds, such as {"delegate": 0.7}, to set your own. Send up to 64 lines at once in items, each with its own speaker and earlier turns, and get one result per line. Your text is scored and not stored.

"Sure, I will" is only a commitment next to the request it answers, so Cue reads up to three earlier turns with every line.

Cue and Jev on the same 116 lines

Four public meetings, line by line. Each answer appears after the time that system took on that line: Cue in your app, median 6 ms; Jev’s API, median 166 ms. The two gave the same cues on 109 of 116 lines. AMI’s own label is beside each line.

Measured October 7, 2026. AMI Meeting Corpus, CC BY 4.0.

What each cue means

  • Commitment (commitment): the speaker promises to do something themselves later. "I'll email you once it's done", "leave that with me".
  • Open question (open_question): the speaker asks the others a real question and waits for an answer. "What did they quote?", "Anyone know if Thursday works?"
  • Hand-off (delegate): the speaker hands a piece of work to someone else. "Priya, could you check the price?", "remind me to call the bank".

Use them to build the follow-up list after a call, keep track of what a team still owes a customer, or let an assistant pick up the work it was handed.

Need a different cue, such as a decision, a risk or a price objection? Tell us what it should catch. SporeLabs trains it on your kind of conversation, proves it against the strongest alternative, and adds it to your API.

How SporeLabs built it

  1. SporeLabs turned conversation transcripts into one input per line: the line, plus up to three earlier turns marked as the same or another speaker.
  2. SporeLabs labelled those lines for the three cues with an open teacher model, AutoJev-27B, and checked the teacher by hand on 200 blind examples first (AUROC 0.966 to 0.976 across the three cues).
  3. SporeLabs trained a small encoder, Ettin 32M, with one scoring head per cue.
  4. SporeLabs fixed each cue's threshold on development data, then ran the test sets once.

Results

SporeLabs tested the released model on the human-labelled test splits of two meeting corpora, AMI and ICSI, next to TypeSafe Jev 1.13 asked the same questions about the same lines.

One test run on the released fp32 model. AUROC ranks every line, so it does not depend on a threshold; the difference has a 95% interval from resampling meetings. F1 is at the threshold the model ships with, with its 95% interval.

Cue ranked commitments and hand-offs better than Jev on AMI. Jev ranked AMI's open questions better, and the two tied on ICSI. AMI marks action items, which include both promises and work handed to someone, so that row counts a line as found when either cue fired. Public corpora have no separate human labels for hand-offs. Every system, metric and interval is in the benchmark.
