# Coding with Llama 3.1, new DeepSeek Coder & Mistral Large

![Summary of code editing skill for the new models, with Sonnet and GPT-3.5 for scale.](/assets/2024-07-new-models.jpg)

Five noteworthy models have been released in the last few days,
with a wide range of code editing capabilities.
Here are their results from
[aider's code editing leaderboard](https://aider.chat/docs/leaderboards/)
with Claude 3.5 Sonnet and the best GPT-3.5 model
included for scale.

- **77% claude-3.5-sonnet**
- 73% DeepSeek Coder V2 0724
- 66% llama-3.1-405b-instruct
- 60% Mistral Large 2 (2407)
- 59% llama-3.1-70b-instruct
- **58% gpt-3.5-turbo-0301**
- 38% llama-3.1-8b-instruct

You can code with all of these models using aider like this:

```
$ python -m pip install -U aider-chat

# Change directory into a git repo to work on
$ cd /to/your/git/repo

$ export DEEPSEEK_API_KEY=your-key-goes-here
$ aider --model deepseek/deepseek-coder

$ export MISTRAL_API_KEY=your-key-goes-here
$ aider --model mistral/mistral-large-2407

$ export OPENROUTER_API_KEY=your-key-goes-here
$ aider --model openrouter/meta-llama/llama-3.1-405b-instruct
$ aider --model openrouter/meta-llama/llama-3.1-70b-instruct
$ aider --model openrouter/meta-llama/llama-3.1-8b-instruct
```

See the
[installation instructions](https://aider.chat/docs/install.html)
and other
[documentation](https://aider.chat/docs/usage.html)
for more details.

## DeepSeek Coder V2 0724

DeepSeek Coder V2 0724 was by far the biggest surprise
and strongest code editing model, coming in 2nd on the leaderboard.
It can
efficiently edit code with SEARCH/REPLACE, unlike
the prior DeepSeek Coder version.
This unlocks the ability to edit large files. 

This new Coder version got 73% on the benchmark,
very
close to Sonnet's 77% but 20-50X less expensive!

## LLama 3.1

Meta released the
Llama 3.1 family of models,
which have performed well on many evals.

The flagship Llama 3.1 405B instruct only 
secured #7 on aider's leaderboard, 
well behind frontier models like
Claude 3.5 Sonnet & GPT-4o. 

The 405B model can use SEARCH/REPLACE to efficiently
edit code, but with a decrease in the benchmark score.
When using this "diff" editing format, its score dropped 
from 66% to 64%.

The smaller 70B model was competitive with GPT-3.5, while
the 8B model lags far behind.
Both seem unable to reliably use SEARCH/REPLACE to edit files.
This limits them to editing smaller files that can
fit into their output token limit.

## Mistral Large 2 (2407)

Mistral Large 2 (2407) scored only 60% on aider's code editing
benchmark. 
This puts it just ahead of the best GPT-3.5 model. 
It
doesn't seem able to reliably use SEARCH/REPLACE to efficiently edit
code,
which limits its use to small source files.
