A common LLM API spec lowers the cost of model switching
◆ 75RelevanceOn a story from The New Stack18h ago
Building agents across multiple providers currently requires expensive custom middleware to handle varying response formats. This move toward a common specification suggests model interoperability is becoming a baseline requirement rather than a feature you have to build yourself.
Takeaways
- A common spec reduces the need for provider-specific response parsing code.
- Moving to a foundation suggests a push for an industry-wide standard.
- Check this spec before building custom abstractions for multi-model support.
