History

Llama 3 8B Instruct became available via the Meta API on 2024-04-18.

Training & availability

Training data has a knowledge cutoff of 2023-12-31 — information about events after that date is unlikely to appear in the model's responses. Meta has not released the underlying model weights — access is via their hosted API only.

Capabilities

Context window: 8K tokens.
Input modalities: text.

Recommended for: cheap.

Limitations

The knowledge cutoff is 27 months old — this model will not know about recent events, releases, or API changes.
The context window (8K tokens) is modest by 2026 standards — unsuitable for processing long documents in a single request.
Text-only — cannot process images, audio, or video inputs.

Pricing

Input: $0.0300 per 1M tokens
Output: $0.0400 per 1M tokens

Quick start

Minimal example using the OpenRouter API. Copy, paste, replace the key.

from openai import OpenAI

client = OpenAI(
    base_url="https://openrouter.ai/api/v1",
    api_key="sk-or-...",
)
resp = client.chat.completions.create(
    model="meta/llama-3-8b-instruct",
    messages=[{"role": "user", "content": "Explain quantum computing in one sentence."}],
)
print(resp.choices[0].message.content)

Price vs quality

Budget pricing

Priced low — good for high-volume tasks. Quality tier pending more benchmark coverage.
