 `askhal` allows you to query all the AI models available in [OpenRouter](https://openrouter.ai/), giving you access to many low-level configuration options. The tool is designed to give users precise control over the model's behavior via context files, system and user prompts, and several fine-tuning parameters.

 ## Features
 
-- Query over 250 [AI models](https://openrouter.ai/models) available in OpenRouter.
+- Query over 290 [AI models](https://openrouter.ai/models) available in OpenRouter.
 - Add a system prompt to provide specific instructions to the model.
 - Enhance the AI's responses by including additional context stored in a file. `askhal` currently supports `docx`, `odt`, `odp`, `ods`, `pdf`, `pptx`, `txt`, and `xlsx` files.
 - Configure the model's behavior using [hyper-parameters](https://docs.novelcrafter.com/en/articles/8677980-tuning-your-model-settings) like temperature, top-k and top-p sampling, frequency penalty, etc.

 ***Note 1**: As you'll expect, the most capable models require you to use a paid account, but costs for individual use tend to be rather low. For example, the [OpenAI'a GPT-4o](https://openrouter.ai/openai/gpt-4o-2024-11-20) model costs less than \$0.0001 per token, which is roughly \$0.01 for a 100-word response. During the initial `askhal` development and testing phase, the total cost was less than $1.50
