Best AI Gateways for Production in 2026: 5 That Hold Up

Best AI Gateways for Production in 2026: 5 That Hold Up

TL;DR * The best AI gateway for production is the one that keeps requests flowing during provider outages, enforces budgets per consumer, and adds negligible latency. Bifrost meets all three: 11 microseconds of overhead at 5,000 requests per second, automatic provider failover, and virtual-key governance. * Five gateways run

Best MCP Gateways in 2026: Compared by Deployment Model and Governance Depth

Best MCP Gateways in 2026: Compared by Deployment Model and Governance Depth

TL;DR * The best MCP gateway for a team is decided by two questions: where the gateway is allowed to run, and how much control it enforces on each tool call. * Six deployment models cover the 2026 market: local container gateways, self-hosted open source, in-VPC or on-premise,

n8n AI Workflow: Routing LLM Nodes Through One Gateway

n8n AI Workflow: Routing LLM Nodes Through One Gateway

TL;DR * The Bifrost AI gateway is OpenAI-compatible, so any n8n LLM node that accepts a custom Base URL can route through it in a single credential change. * A single Bifrost virtual key becomes the per-workflow credential in n8n, carrying budget caps, rate limits, and provider allow-lists

Best AI Governance Tools and Platforms in 2026: Policy, Runtime, and Observability Layers Compared

Best AI Governance Tools and Platforms in 2026: Policy, Runtime, and Observability Layers Compared

TL;DR * The AI governance stack has three functional layers: policy (define rules, virtual keys, budgets, allow/deny lists, model access), runtime (enforce rules at request time through the gateway, guardrails, PII redaction, rate limits), and observability (measure and audit through token/cost tracking, prompt logging, audit trails, tracing). * Bifrost,

MCP Authentication: OAuth 2.1 Patterns for Agent Tool Access

MCP Authentication: OAuth 2.1 Patterns for Agent Tool Access

TL;DR * The MCP authorization specification requires OAuth 2.1, mandatory PKCE, and a strict separation between the authorization server that issues tokens and the resource server (the MCP server) that validates them. * RFC 9728 protected resource metadata and RFC 8707 resource indicators bind an access token to one specific

What Are MCP Guardrails? How Tool-Level Policy Enforcement Works

What Are MCP Guardrails? How Tool-Level Policy Enforcement Works

TL;DR * MCP guardrails validate tool arguments before a call executes and tool results after it returns, a boundary that LLM-only content filters never inspect. * Bifrost evaluates MCP guardrail rules with CEL expressions matched against mcp_client, mcp_tool, and mcp_arguments, then routes matches to one or more

OpenTelemetry for LLM Observability: Traces and Metrics

OpenTelemetry for LLM Observability: Traces and Metrics

TL;DR * LLM observability is the practice of capturing traces, metrics, and logs from model calls so teams can debug latency, cost, token usage, and errors across every provider in production. * OpenTelemetry (OTLP) is the vendor-neutral standard for that telemetry, and its GenAI semantic conventions define a common set
