Gunakan rute ini untuk memulai prediksi bergaya Replicate di CometAPI dan mendapatkan prediction id untuk polling nanti. ## Checklist permintaan pertama * Letakkan setiap parameter model di dalam objek `input` * Mulai dengan `black-forest-labs/flux-schnell` untuk permintaan pertama yang paling cepat * Biarkan permintaan pertama hanya berupa teks kecuali Anda secara khusus membutuhkan `input_image` atau `input_images` * Simpan prediction `id` yang dikembalikan untuk pemeriksaan status ## Alur tugas Kirim model ID path dan objek `input` melalui endpoint ini. Simpan `id` yang dikembalikan, karena Anda membutuhkannya untuk polling nanti. Lanjutkan dengan [Dapatkan prediksi Replicate](./replicate-query) hingga `output` terisi atau muncul error. ## OpenAPI ````yaml api/openapi/image/replicate/post-create-predictions-general.openapi.json POST /replicate/v1/models/{models}/predictions openapi: 3.1.0 info: title: Create Predictions - General API version: 1.0.0 description: >- Create a Replicate-style prediction on CometAPI and receive a prediction id for later polling. servers: - url: https://api.cometapi.com security: - bearerAuth: [] paths: /replicate/v1/models/{models}/predictions: post: summary: Create a Replicate prediction description: >- Submit a prediction request using a model id in the path and a provider-specific `input` object in the body. operationId: create_predictions_general parameters: - name: models in: path required: true description: >- Replicate model id, for example `black-forest-labs/flux-schnell` or `black-forest-labs/flux-kontext-pro`. schema: type: string requestBody: required: true content: application/json: schema: type: object required: - input properties: input: type: object description: >- Provider-specific model input.
