The relationship between Doubao products and Seed models

Seed is ByteDance’s basic model series. The official introduced Seed2.1 on June 23 and stated that relevant entrances have been provided in Doubao, TRAE and Volcano Engine API. Doubao is the product to use, and Seed2.1 is the underlying model series. The office mode, development environment and interface openness capabilities of the product should be confirmed separately.

Officially emphasized capability direction

The focus of this release includes multi-step tool tasks, software engineering delivery, and multi-modal understanding such as vision and video. For ordinary users, it can be understood as moving from answering questions to processing documents and executing processes. However, the plans and documents generated by the model still need to be checked by the business leader. It is not appropriate to skip the check just because the output format is complete.

What type of team work is suitable (ChinaOPC analysis)

The team that provides operational support to the enterprise can start with a weekly report: read the confirmed operation table, find out the changes, generate charts and issues to be discussed. First, it is required to separate the original facts from the explanation. For example, the sales drop is calculated from the table, while the "customer demand change" may be just speculation and requires other evidence.

If the customer provides a mixture of pictures, PDFs and tables, make it clear which one is the official document. Models can assist in sorting, but just because the numbers on a promotional poster are larger, the data on the poster cannot be used first. It is best to have each important number back to the source document and statistical interval.

How to check file delivery

Tables check for formula references, null values, and totals, presentations check for units, legends, and footnotes, and documents check for consistency between titles and attachments. Open the final export file at least once, rather than just looking at the preview in the conversation. When it comes to real customer information, first confirm that the team has the authority to hand over these materials to the selected service for processing.

Confirm the environment and budget before accessing

Trialing the product on the web helps understand the workflow, while API access also requires file handling, permissions and storage arrangements. Don't think of the engineering capabilities in TRAE as all the functions that automatically come with a text interface. When comparing plans, record the total time taken to complete the same document, the amount of manual modifications, and service costs, and then decide whether to include it in formal delivery.
