Forge AI is giving away free credits to sample GPT-5.6, Grok 4.5, Kimi K3, and more models today. New signups receive roughly $50–60 in starter balance without a credit card. You get one API key and base URL for multiple frontier models. Therefore, developers can compare prompts before committing to paid tiers.
What Forge AI Is Giving Away Free Credits to Sample GPT-5.6, Grok 4.5, Kimi K3 and More Includes
First, register at Forge AI to see your exact starter balance. The promotional amount may vary slightly. Next, copy your API key and grab the model ID from the Models tab. Finally, set your base URL to forge-gateway-api.fly.dev/v1. This OpenAI-compatible structure works instantly with Cursor, Claude Code, or Aider.
The catalog covers top developer interests right now. GPT-5.6 and Grok 4.5 represent current frontiers from OpenAI and xAI. Additionally, Kimi K3 is Moonshot AI’s massive open-weight model. It saw huge demand upon launch. GLM 5.2 from Zhipu rounds out this lineup. Testing all four usually requires separate accounts and billing setups.
This approach mirrors other popular free tier promotions. For example, ZenMux gained traction when it added Kimi K3. Similarly, TokenRouter drove sign-ups with free GLM-5.2 access. However, Forge offers an open-ended balance rather than time-limited windows. You can use credits across any model or call volume for experiments.
How to Claim Your Starter Credits
The setup process takes about three minutes. Sign up and confirm your dashboard balance first. Then, copy your API key and find your desired model ID string. Set the base URL and paste in your key. Send a short test call before running longer agent loops. This confirms routing works and provides a reference output.
