Hey everyone, just wanted to share a find from the weekend. I was looking for ways to test out some of the newer agentic workflows without hammering my personal API limits, and I found this platform called Mixflow AI. They’re currently giving out $150 in credits to new signups. I grabbed it to play around with their API proxy, and it actually works perfectly with the standard CLI tools for Codex, Claude, and Gemini. ⚠️ IMPORTANT CAVEAT: While the credits work and the latency is good, remember that you are routing your traffic through a third-party proxy. I would strictly advise against using this for proprietary company code or anything containing PII/secrets. It’s awesome for generating boilerplate, learning the tools, or working on open-source side projects, but just practice good hygiene and keep the sensitive stuff local until their data policy is clearer. That said, if you want to burn some free compute on the high-end models (GPT-5.2, Opus 4.5, Gemini 3 Pro), here is the config I used to get everything running locally:
- Codex CLI Setup Great for testing the new gpt-5.2-codex model. Install: npm install -g u/openai /codex Config: Update your ~/.codex/config.toml : Ini, TOML
Mixflow config model = “gpt-5.2-codex” model_provider = “mixflow” model_reasoning_effort = “high” [model_providers.mixflow] name = “Mixflow” base_url = “https://app.mixflow.ai/api/mixflow/v1/chat/completions” http_headers = { “X-MF-Key” = “YOUR_KEY” } wire_api = “responses”
Run: codex --provider mixflow “build a react component for a login form” 2. Claude Code CLI I used this with claude-opus-4-5 for some heavy refactoring tasks. Install: npm install -g u/anthropic-ai /claude-code Env Vars: Add to your shell profile ( ~/.bashrc or ~/.zshrc ): Bash export ANTHROPIC_BASE_URL=“https://app.mixflow.ai/api/anthropic” export ANTHROPIC_API_KEY=“YOUR_KEY” # You can also use claude-sonnet-4-5 here export ANTHROPIC_MODEL=“claude-opus-4-5” Run: claude 3. Gemini CLI The easiest setup since you can just use npx . Env Vars: Add to your shell profile: Bash export GEMINI_API_KEY=“YOUR_KEY” export GOOGLE_GEMINI_BASE_URL=“https://app.mixflow.ai/api/gemini” Run: npx u/google /gemini-cli I’ve been running the Codex agent for a few hours today and haven’t hit a cap yet. Enjoy the credits while they last, but again—keep your private keys and sensitive data out of the prompt! Let me know if you need any help! Will gladly answer how to set this one up! submitted by /u/Biohaaaaaacker
