Time-Consuming Model Upgrades

“Slash LLM API Costs with This Open-Source Gateway Just open-sourced Squirrel — an LLM API Gateway built to solve the nightmare of managing multiple models, providers, and prompts across different projects.<p>If you are building AI apps, managing agents, or running backend services, you have probably hit these walls:<p>Upgrading models is a grind. Updating hardcoded strings across 10+ repositories takes too much time.<p>Bleeding money blindly. Provider prices fluctuate, and tracking costs across multiple vendors is impossible manually.<p>Debugging is pure guesswork. Without full request&#x2F;response logs, fixing broken prompts is a shot in the dark.<p>I built Squirrel to fix exactly this. Here is what it does out of the box:<p>Model Mapping (Change once, apply everywhere) Stop hardcoding specific models like gpt-4o or claude-3.5-sonnet. Map a virtual name (like my-smart) to a provider in the gateway. Want to upgrade all your apps at once? Just update the mapping in Squirrel. It takes effect instantly across all projects with zero code changes required.<p>Cost-Based Auto-Routing Set your provider pricing, and Squirrel automatically routes requests to the cheapest available option. It also supports priority, weight-based, and round-robin strategies.<p>Complete Observability Logs every single API call, including streaming responses. Check the admin dashboard to see the exact prompt sent, the model&#x27;s output, token usage, and Time to First Byte (TTFB). This is an absolute lifesaver for debugging and fine-tuning.<p>Auto-Retry &amp; Failover If a provider throws a 500 error or times out, Squirrel seamlessly switches to a backup provider. Your client-side code does not need to handle a thing.<p>Protocol Compatibility Works natively with OpenAI and Anthropic SDKs, and auto-translates protocols between them under the hood.<p>Tech Stack: Python (FastAPI) + Next.js + PostgreSQL&#x2F;SQLite. One-click deployment via Docker Compose.<p>Fully open-source under the MIT license. It is still under active development, so feedback, issues, and PRs are incredibly welcome.<p>Check it out here: <a href="https:&#x2F;&#x2F;github.com&#x2F;mylxsw&#x2F;llm-gateway" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;mylxsw&#x2F;llm-gateway</a>”
