🥇 Google AI Studio · Gemini 2.5 Flash (free) ​

Recommended #2. Gemini 2.5 Flash has a huge context window and strong reasoning. It's a great fit for the 🧠 Executive Summary in rescue handovers.

1. Get a free key ​

  1. Open aistudio.google.com/apikey and sign in with a Google account.
  2. Click Create API key and copy it (it starts with AIza).

2. Connect it (one line) ​

bash
bouncer config --preset gemini-gold --key AIza_your_key_here

Or keep the key in your environment (GEMINI_API_KEY or GOOGLE_API_KEY):

bash
export GEMINI_API_KEY=AIza_your_key_here
bouncer config --preset gemini-gold

Privacy on the free tier

Google's terms for unpaid Gemini API usage allow prompts to be used to improve Google products. If your prompts are sensitive, use a paid key or Ollama instead.

Latency

Flash usually answers within Bouncer's 1500 ms budget. A slow reply simply falls back to Level 1 for that prompt. Run bouncer stats to see how often that happens ("fail-opens"), and raise the budget with bouncer config --timeout 2500 if needed.

Troubleshooting ​

  • failed (HTTP 400/403): the key is invalid, or the Gemini API isn't enabled for its project. Create a fresh key in AI Studio.
  • failed (HTTP 429): free-tier quota reached. Bouncer stays on Level 1 until it resets.
  • Remove it: bouncer config --clear.
