Describe the bug
I'm getting ' ERROR There was a problem with the ollama API request.' when trying to use mods with Ollama

This used to work with no issues till recently, I don't know if there was an update on mods or Ollama that broke something.

Setup
Please complete the following information along with version numbers, if applicable.

• macOS 14.6.1
• zsh 5.9 (arm-apple-darwin22.1.0)
• Alacritty 0.13.2 (1)
• tmux 3.4
• ollama version is 0.3.11
• mods version v1.6.0 (84099bd)

Steps to reproduce the behavior:

1. brew install mods ollama
2. and run:

mods -f "Hello, world" --api ollama --model llama3:latest

3. this will give the bellow error:

   ERROR  There was a problem with the ollama API request.

  error, status code: 404, message: json: cannot unmarshal number into Go value of type openai.ErrorResponse

I can confirm my Ollama setup is wroking:

curl  http://127.0.0.1:11434/v1/models/llama3:latest
{"id":"llama3:latest","object":"model","created":1726132093,"owned_by":"library"}

 curl -X POST http://127.0.0.1:11434/v1/completions -H "Content-Type: application/json" -d '{"model": "llama3:latest", "prompt": "Hello, world!", "max_tokens": 50}'
{"id":"cmpl-855","object":"text_completion","created":1727250150,"model":"llama3:latest","system_fingerprint":"fp_ollama","choices":[{"text":"Hello, world","index":0,"finish_reason":"stop"}],"usage":{"prompt_tokens":14,"completion_tokens":5,"total_tokens":19}}

see my mods.yml config file at the end of this post.

Expected behavior

• mods should use Ollama llama3 model and respond to the prompt

Same here, I rolled back to v1.3.1 and it is working again.
I uninstalled the current 1.6.0 and tested all versions until I hit the first that worked again.
To install that version using go use go install github.com/charmbracelet/mods@v1.3.1

try changing ollama.base-url to http://127.0.0.1:11434/api instead of http://127.0.0.1:11434/v1. Worked for me. Ollama API doc for reference: https://github.com/ollama/ollama/blob/main/docs/api.md#generate-a-chat-completion
