  • Databricks drove down AI coding spend 70%
    Omniagent looks quite similar to OpenRouter (https://openrouter.ai/). - Source: Hacker News / 3 days ago
  • GLM-5.2 is the step change for open agents
    It's very easy to use other providers. See https://openrouter.ai/ which also let's you filter by where the provider is hosted and their data retention policy. - Source: Hacker News / about 2 months ago
  • Testing GLM-5.2 on OpenCode: I'm impressed!
    If you want to try it yourself: grab OpenCode, point it at OpenRouter, select GLM 5.2, and give it a real task instead of a benchmark. The z.ai docs have the rest of the details. - Source: dev.to / about 2 months ago
  • AI Gateways in 2026: a field guide to the 106 cost problem
    Hosted, minimal ops. You want to be calling models in five minutes and you are fine paying a small fee for it. OpenRouter is the marketplace default โ€” 400+ models, ~5.5% on credits. Vercel AI Gateway and Cloudflare AI Gateway go further and charge 0% markup, billing you at provider list price while adding routing and caching on top. - Source: dev.to / about 2 months ago
  • Self-hosting OpenClaw: a money trap and two silent failures
    I use OpenRouter as the single door to a pile of models. Its BYOK (bring-your-own-key) feature has a trap. You add your own OpenAI key for a model, flip on "Always use for this provider," and read that as never spend OpenRouter credits. It doesn't mean that. - Source: dev.to / 2 months ago
