The invention relates to the technical field of computers, and relates to a model training method, a formula identification method, a device, a medium and equipment, so as to improve the accuracy of a formula identification model obtained by training. The formula recognition model comprises a coding layer and a decoding layer, and the model training method comprises the steps that a sample image is acquired, the sample image comprises a sample formula, and the sample formula is labeled with a sample formula label; inputting the sample image into a coding layer provided with a first training parameter to obtain a sample formula image feature output by the coding layer; inputting the sample formula image features into a decoding layer provided with a second training parameter to obtain a sample formula recognition result output by the decoding layer; calculating a target loss value according to the sample formula identification result and the sample formula label; and adjusting a first training parameter and a
