meta-llama | 8,192 token context | $0.03/M input, $0.04/M output. Meta developed and released the Meta Llama 3 family of large language models (LLMs), a collection of pretrained and instruction tuned generative text models in 8 and 70B sizes.
Meta Llama 3 8B Instruct is Meta's smaller instruction-tuned model from the Llama 3 family, sitting alongside a 70B sibling. At fractions of a cent per thousand tokens it is one of the cheaper hosted options around, and the 8B size means it runs fast. A reasonable pick for everyday chat, light writing tasks and anyone watching their API bill.

Known for

  • Very low API cost: $0.03 per million input tokens, $0.04 output
  • Fast responses typical of an 8B-class model
  • Part of Meta's Llama 3 family, with a larger 70B sibling available
  • Instruction-tuned for direct question-and-answer and task completion

Watch out for

  • 8,192-token context is short by current standards; long documents will need chunking.
  • Open weights exist elsewhere, but this listing does not carry them: check the licence before any commercial deployment.
  • The 8B size trails the 70B on complex reasoning and nuanced writing tasks.

Prompts to try

Rewrite for plain English
Rewrite the following paragraph so a non-specialist can understand it in one read. Cut jargon, keep every fact, and aim for sentences under 20 words: 'The utilization of advanced machine learning paradigms facilitates the automated extraction of latent semantic representations from unstructured corpora, enabling downstream inferential tasks with minimal human intervention.'
Draft a short email
Write a short, professional email declining a meeting request. The sender asked for 90 minutes next Tuesday to pitch a new software tool. I am not interested but want to leave the door open for a brief async summary instead. Keep it under 100 words and do not use the phrase 'I hope this email finds you well'.
Explain a concept simply
Explain how a transformer neural network decides which words in a sentence to pay attention to. Use an analogy a curious 16-year-old would follow. No bullet points, just a clear paragraph of plain prose.

Questions people ask

Can I run Meta Llama 3 8B Instruct locally?
Open weights for Llama 3 8B exist and can be run locally via tools like Ollama, but this listing covers the hosted API; check Meta's release page for the weights and licence terms before downloading.
What does it cost and how long is the context window?
The API is priced at $0.03 per million input tokens and $0.04 per million output tokens, with a context window of 8,192 tokens.
How does the 8B compare to the 70B version?
Both are instruction-tuned Llama 3 models; the 70B is the stronger choice for complex reasoning and longer, more nuanced tasks, while the 8B is faster and cheaper for simpler workloads.
Captain's verdict
A sensible budget pick for fast, simple tasks — just know the 70B exists when the job gets harder.

How this score adds up
This model has no popularity data from any source yet, so it carries a stand-in number below 7,000° that keeps the lists complete. It never ranks above a model with data. The breakdown appears here as soon as a source reports it.
Glossary: the terms used here
Heat score
One number for how much a model is used and wanted right now, from 0° to 9,999°. Every list on this site that says hottest is sorted by it and nothing else.
Floor
The 7,000° every model with real data starts from. The scale runs from 0° to 9,999°; the part below the floor is reserved for stand-ins (models without data), so that a model with data always ranks above one without. The floor is the same for everyone and decides nothing; the degrees above it are the measurement.
Download-equivalents
Everything the score treats as a download, added up: downloads themselves, each torrent seeder as 1,000, each AI Horde image and each run on a generation site as one.
Log scale
Counting by tens, not by ones: going from 1,000 to 10,000 downloads adds the same degrees as going from 10,000 to 100,000. It keeps giants from crowding out everything else.
Likes
Thumbs up and likes from every source, worth half a download each on the log scale.
Adoption rate
How many downloads a day a model gets right now, from the difference between two readings of a source. A quarter of the weight of the download term.
Measured and estimated
Measured means two readings of a source exist and the difference is real. Estimated means only today's total is known and the past is spread over the model's life; the site says which one it is showing.
Seeder
Someone who keeps a copy of the weights online for others to download over a torrent, or a hosted mirror doing the same. Each one counts as 1,000 downloads.
AI Horde
A volunteer network that generates images for free on donated computers. The number of images it has made with a model is public, and each counts as one download.
Generation sites
Sites that host their own copies of a model and let people generate with it, such as PixAI, SeaArt and Yodayo. Their downloads count like Civitai's and each generation run as one download.
OpenRouter tokens
A text model served through an API, such as Claude or GPT, has no weights to download, so its usage is measured in tokens: the pieces of text it read and wrote through OpenRouter, a gateway many apps use, over the last 30 days. Every 10,000,000 tokens count as one download. Source: OpenRouter (openrouter.ai/rankings), CC BY 4.0.
Full model (checkpoint)
The weights themselves, the file that generates on its own. It gets a bonus because add-ons depend on it.
LoRA and embedding
Small add-on files that steer someone else's weights toward a style, a character or a concept. They cannot run alone.
Family and weights
The base a model is built on, such as SD 1.5, SDXL, Flux or Wan. Every model inherits the release date of its family's weights.
Age
Degrees taken off for how long ago the family's weights came out: 150° a year, up to 750°. It keeps old downloads that had years to pile up from freezing the top of the list.
Family boost
A small, bounded nudge for LoRAs of a family this site is pushing forward right now, always listed in the breakdown.
Stand-in score
A stable number below the floor given to a model no source reports on yet, so lists stay complete. It never ranks above a model with data.
New! (grace period)
A model less than 7 days old shows New! instead of a score and holds no place in the rankings. Its score is computed from day one, but a model one day old grows faster than anything, so without the wait the week's #1 would always be whatever came out yesterday rather than what held up for a week.
Trend
How a model's growth over a period compares with the typical model's growth over the same period. Faster than typical reads as a rise, slower as a fall.
Typical model
The middle of the catalog: half the models with a figure grew faster over the period, half slower.
