I loved this post from Andre about running sentiment analysis in the browser using a model that he'd trained on embeddings generated from a YouTube comments data was great and shows that you don't have to run everything through the full language model and instead can use just the embedding APIs to get a decent result.

The client side part of the code can be seen below:

const input = 'Hello, your video is amazing!'; const embedResult = await genAi.models.embedContent({ model: 'text-embedding-004', contents: [input], }); const embeddings = embedResult.embeddings.map(embedding => embedding.values); const outputTensor = await model.predict(tf.tensor2d(embeddings)); const argmax = await tf.argMax(outputTensor, 1).array(); const labels = ['Positive', 'Neutral', 'Negative']; const results = argmax.map(i => labels[i]); console.log(results);

const probabilities = await tf.softmax(outputTensor, 1).array() console.log(probabilities);

Stay in the loop.
