Anthropic

To work with Anthropic’s models, you need to provide your Anthropic API key either in the ANTHROPIC_API_KEY environment variable or via the --anthropic-api-key command line switch.

PairPilot has some built in shortcuts for the most popular Anthropic models and has been tested and benchmarked to work well with them:

python -m pip install -U PairPilot-chat

export ANTHROPIC_API_KEY=<key> # Mac/Linux
setx   ANTHROPIC_API_KEY <key> # Windows, restart shell after setx

# PairPilot uses Claude 3.5 Sonnet by default (or use --sonnet)
PairPilot

# Claude 3 Opus
PairPilot --opus

# List models available from Anthropic
PairPilot --list-models anthropic/

Anthropic has very low rate limits. You can access all the Anthropic models via OpenRouter or Google Vertex AI with more generous rate limits.

You can use PairPilot --model <model-name> to use any other Anthropic model. For example, if you want to use a specific version of Opus you could do PairPilot --model claude-3-opus-20240229.
