Very simple POC, hits the yr.no API for the weather forecast, summarises it into a smaller string to minimise tokens that ChatGPT needs to process, and then requests that ChatGPT create a Haiku from it.

With ChatGPT's API you pay by the tokens, basically 'words', both sent and received, so while we could ask for the weather forecast as a short fairytale, a Haiku is at least short and sweet.

ChatGPT is spendy, so I'm caching these haiku in AWS DynamoDB based on coordinates and the hour. If one has been generated already for your coordinates (to one decimal place) and for the given hour, then it will be fetched from DynamoDB instead of regenerating from ChatGPT.

Next steps:

• Take params for the coordinates
• Put it on an AWS Lambda
• Set up API Gateway to proxy calls to the Lambda
• Make a simple front-end for it
• Optimise/minimise the weather data being used
• Cache ChatGPT results per hour x latlon in DynamoDB
• CI/CD for putting it on AWS
• See if ChatGPT can be initialised with a template, so we can just send comma separated values to further miminise token count
• Maybe make an IOS app/widget for it

Running

In one terminal

cd lambda
cargo lambda watch

In another

cargo lambda invoke weather_haiku --data-ascii '{ "latitude": "53.34", "longitude": "-6.26" }'

Build

cargo lambda build --release --arm64 --output-format zip

## Deploy

cargo lambda deploy --iam-role arn:aws:iam::XXXXXXXXXXXX:role/your-role-here
