gemma-7b-it-lora Beta
Text Generation • GoogleThis is a Gemma-7B base model that Cloudflare dedicates for inference with LoRA adapters. Gemma is a family of lightweight, state-of-the-art open models from Google, built from the same research and technology used to create the Gemini models.

Input
- Prompt object
-
promptstring min 1 max 131072The input text prompt for the model to generate a response.
-
imageone of-
0arrayAn array of integers that represent the image data constrained to 8-bit unsigned integer values
-
itemsnumberA value between 0 and 255
-
-
1stringBinary string representing the image contents.
-
-
rawbooleanIf true, a chat template is not applied and you must adhere to the specific model's expected formatting.
-
streambooleanIf true, the response will be streamed back incrementally using SSE, Server Sent Events.
-
max_tokensinteger default 256The maximum number of tokens to generate in the response.
-
temperaturenumber default 0.6 min 0 max 5Controls the randomness of the output; higher values produce more random results.
-
top_pnumber min 0 max 2Adjusts the creativity of the AI's responses by controlling how many possible words it considers. Lower values make outputs more predictable; higher values allow for more varied and creative responses.
-
top_kinteger min 1 max 50Limits the AI to choose from the top 'k' most probable words. Lower values make responses more focused; higher values introduce more variety and potential surprises.
-
seedinteger min 1 max 9999999999Random seed for reproducibility of the generation.
-
repetition_penaltynumber min 0 max 2Penalty for repeated tokens; higher values discourage repetition.
-
frequency_penaltynumber min 0 max 2Decreases the likelihood of the model repeating the same lines verbatim.
-
presence_penaltynumber min 0 max 2Increases the likelihood of the model introducing new topics.
