meta /llama-2-7b:acdbe5a4

Playground API

Input

prompt

*string

Shift + Return to add a new line

Prompt to send to Llama v2.

max_new_tokens

integer

(minimum: 1)

Maximum number of tokens to generate. A word is generally 2-3 tokens

Default: 500

min_new_tokens

integer

(minimum: -1)

Minimum number of tokens to generate. To disable, set to -1. A word is generally 2-3 tokens.

Default: -1

temperature

number

(minimum: 0.01, maximum: 5)

Adjusts randomness of outputs, greater than 1 is random and 0 is deterministic, 0.75 is a good starting value.

Default: 0.95

top_p

number

(minimum: 0, maximum: 1)

When decoding text, samples from the top p percentage of most likely tokens; lower to ignore less likely tokens

Default: 0.95

top_k

integer

(minimum: 0)

When decoding text, samples from the top k most likely tokens; lower to ignore less likely tokens

Default: 250

repetition_penalty

number

(minimum: 0.01, maximum: 5)

Penalty for repeated words in generated text; 1 is no penalty, values greater than 1 discourage repetition, less than 1 encourage it.

Default: 1.15

repetition_penalty_sustain

integer

(minimum: -1)

Number of most recent tokens to apply repetition penalty to, -1 to apply to whole context

Default: 256

token_repetition_penalty_decay

integer

(minimum: 1)

Gradually decrease penalty over this many tokens

Default: 128

debug

boolean

provide debugging output in logs

Default: false

Run this model in Node.js with one line of code:

npx create-replicate --model=meta/llama-2-7b

or set up a project from scratch

Install Replicate’s Node.js client library:

npm install replicate

Set the REPLICATE_API_TOKEN environment variable:

export REPLICATE_API_TOKEN=<paste-your-token-here>

Find your API token in your account settings.

Import and set up the client:

import Replicate from "replicate";

const replicate = new Replicate({
  auth: process.env.REPLICATE_API_TOKEN,
});

Run meta/llama-2-7b using Replicate’s API. Check out the model's schema for an overview of inputs and outputs.

const output = await replicate.run(
  "meta/llama-2-7b:acdbe5a4987a29261ba7d7d4195ad4fa6b62ce27b034f989fcb9ab0421408a7c",
  {
    input: {
      debug: false,
      top_k: 250,
      top_p: 0.95,
      temperature: 0.95,
      max_new_tokens: 500,
      min_new_tokens: -1,
      repetition_penalty: 1.15,
      repetition_penalty_sustain: 256,
      token_repetition_penalty_decay: 128
    }
  }
);
console.log(output);
