What Real Users Say

★★★★★Currently, I use other platforms for images (Nano Banana Pro) and for LLMs. I'd like to migrate my entire setup to CometAPI. Your pricing for the LLM 'gemini-3-pro-preview-thinking' is excellent. I'd like to consolidate all my traffic (LLM + image generation) with you.
Daniel SchweigOperator at Kindle Direct Publishing
★★★★★As developers, we really enjoy communicating with you and your support team, and we would not want to switch to alternative API services.
Leonid DolgirevFounder of WB Sharks AI
★★★★★We sincerely appreciate you and the CometAPI team for the excellent API support, partnership, and assistance—your help has enabled the successful use of API keys in the Claude Code setup and provided valuable second opinions, making you a fantastic partner.
