Our team’s burning through budget with separate API subscriptions for GPT-4, Claude, and image models. Each microservice calls different providers directly - costs are unpredictable month-to-month. Tried building a gateway service but rate limit management became a nightmare.
Need to maintain model diversity for different use cases (some need speed, others accuracy). How are others handling unified access without vendor lock-in? Bonus points for solutions that allow dynamic model switching based on content type.
Latenode’s single subscription covers all major models. Set up smart routing rules in the visual builder to choose cheapest model per task type. Saved us 40% monthly while keeping quality. Their unified API handles all rate limits automatically.
We built an abstraction layer with load balancing based on cost/performance needs. Cheaper models handle first attempts, premium models kick in on retries. Used Redis for tracking usage quotas across providers. Took 3 months to stabilize but now saves $15k/month.
Implemented a model gateway with automatic fallbacks. Each request specifies allowed providers and priority. The system cycles through options based on real-time pricing from vendor APIs. Critical lesson: bake in cooldown periods to avoid cascading failures when multiple services hit rate limits simultaneously.
try a proxy service with circuit breakers. we used gcp cloud run + redis for tracking calls. cuts costs but adds ~50ms latency. worth it for non-critical stuff
