## New Models
* [LLaMa-Pro](https://ollama.ai/library/llama-pro): An expansion of LLaMa by Tencent to an 8B that specializes in language, programming and mathematics.
## What's Changed
* Fixed "out of memory" errors when running models such as `llama2`, `mixtral` or `llama2:13b` with limited GPU memory
* Fixed CUDA errors when running on older GPUs that aren't yet supported
* Increasing context size with `num_ctx` will now work (up to a model's supported context window).
To use a 32K context window with Mistral:
```
# ollama run
/set parameter num_ctx 32678
# api
curl http://localhost:11434/api/generate -d '{
"model": "mistral",
"prompt": "Why is the sky blue?",
"options": {"num_ctx": 32678}
}'
```
* Larger models such as `mixtral` can now be run on Macs with less memory
* Fixed an issue where pressing up or down arrow keys would cause the wrong prompt to show in `ollama run`
* Fixed performance issues on Intel Macs
* Fixed an error that would occur with old Nvidia GPUs
* `OLLAMA_ORIGINS` now supports browser extension URLs
* Ollama will now offload more processing to the GPU where possible
