Great comparison! The gateway space has really matured over the last year.

Our criteria when we picked a gateway:

• Model breadth: How many models do you actually need? We use 40+ (DeepSeek, Qwen, Kimi, GLM, GPT, Claude, Grok, etc.)
• Protocol support: Chat Completions, Responses, and Messages. Different tools speak different protocols.
• Transparent pricing: All rates listed upfront. No surprise fees.
• No lock-in: Pay as you go, credits never expire.

We ended up using JZS Token. It hits all these points. The big win for us was having all the models we need through one OpenAI-compatible endpoint. Switching between models is just changing the model name - no SDK changes, no different auth.

For a small team or solo developer, this is a huge productivity boost. Instead of integrating with 5 different providers, you integrate once and have access to everything.

Good roundup. This is a really useful overview of the options out there.
