Collecting feedback · 1/3

Classify the reported market event using the supplied taxonomy.

Example 1 of 3

Acquisition rumor is not confirmation

Model input

Classification rules: Synthetic news taxonomy. Label the event explicitly reported: guidance_change for a revised company forecast, acquisition for an announced purchase of another company, earnings_result for reported financial results, or other. Status is confirmed only for an explicit company announcement or reported result; an attributed unconfirmed report is rumored. Retain the supporting source quote. Do not predict prices.
Article: Synthetic article: Sources familiar with the talks say Alder Systems may buy Birch Labs. Neither company has confirmed a deal.

Step 02

Model Sweep

Compare models on the same expert annotations, then choose a quality–cost tradeoff.

Compare models on expert agreement and cost. The interactive chart uses illustrative measurements.

Illustrative sweep · select Value or Best to use that model in your function.

Step 03

Deployment

Call Sutro Functions like any other software. Swap the model as soon as something more performant is released.
