Routing LLM Requests by Difficulty in Bifrost : Complexity Router

"Write a one-line summary of this doc" and "refactor this 2000 loc module for multi-tenancy" both arrive as the same chat completion request - unless your application already sends them to different models. If you pin both to your strongest model, you burn money on the easy half. If you pin both to a cheap model, the hard half comes back broken. This mismatch keeps showing up now that workloads are mixed - chat alongside code review alongside agents alongside long-form reasoning, all flowing th

Code Mode and the Architecture of Token-Efficient MCP AgentsCode Mode

The Context Window Problem If you've built an agent that connects to more than a handful of MCP servers, you've already run into this. Every tool definition from every connected server gets loaded into the model's context window on every request. Five servers with 30 tools each means 150 tool definitions sitting in context before the model reads a single word of your prompt. This is more than a theoretical concern. Anthropic's engineering team documented a five-server setup where tool definiti

Beyond latency-based routing: Adaptive load balancing in Bifrost

Most teams running multi-provider LLM stacks have moved past pure round-robin for traffic distribution across providers and API keys. They've adopted latency-based routing: measure response times, penalise slow backends, shift traffic toward the fast ones. The approach is reasonable, but it has a failure mode that's easy to miss until you're debugging a production incident. A 6-second response from your LLM provider can be either fast or slow, and a flat latency threshold has no way to tell whi

Your Semantic Cache Has a Grey Zone Problem

If you're running LLMs in production, you've probably built (or thought about building) a semantic cache. The pitch is simple: embed incoming prompts, find near-duplicates, serve the cached response, skip inference. It works. Except when it doesn't. A new paper from Apple introduces Krites, a caching policy that quietly fixes one of the most annoying problems in semantic caching, ie. the similarity grey zone, without adding a single millisecond to your serving latency. Let's break it down. Th

Access GPT, Gemini, Claude, Mistral etc. through 1 Gateway: Configure Providers in Bifrost

When building AI-powered applications, chances are you don’t want to rely on a single provider: * Claude for reasoning-heavy tasks * GPT-4o for multimodal inputs * Gemini for Google ecosystem integrations * Mistral for fast, cost-effective completions Each provider has different SDKs, auth methods, rate limits, and response formats. Maintaining them quickly becomes messy. Bifrost solves this by acting as a unified AI gateway: one API surface, multiple providers behind it. In this post, we

Your Primary LLM Provider Failed? Enable Automatic Fallback with Bifrost

When building applications that depend on external LLM APIs, provider failures are inevitable. Network timeouts, rate limits, model unavailability, and service outages all cause request failures that break application functionality. This post explains how to implement automatic fallback mechanisms using Bifrost to maintain service availability when primary providers fail. Failure Scenarios in LLM Applications LLM API calls can fail for several reasons: * Rate limiting: HTTP 429 responses wh

From Text to Vision: Multimodal Support in Bifrost

Modern AI applications are rapidly moving beyond text-only interactions. Today's systems need to process images, generate speech, and transcribe audio, often within the same workflow. While individual providers offer these capabilities, building a robust multimodal system that spans multiple AI providers introduces significant complexity around API differences, error handling, and failover strategies. Bifrost, an open-source AI gateway, addresses these challenges by providing unified multimodal
