Thank you to everyone who joined our October town hall. We covered security, stability and performance work, and the product updates from the month.

LiteLLM Auto Router now supports Laya and Bespoke Nimble as self-hosted classifiers. Run either model on your infrastructure to choose which completion model handles each request. Your application keeps calling the same router endpoint.

The LiteLLM gateway course walks you through how the gateway, Router, and SDK work together. We built it for developers and platform teams deploying LiteLLM, and contributors who want to understand the code before opening a pull request.

Your gateway tells you what your team spends on AI. It doesn't tell you what that spend produced.

The LiteLLM ROI Calculator compares gateway spend with the engineering work your team ships. It reads spend per user from LiteLLM, estimates the effort in each merged pull request with a model you choose, and matches people by email. The result is one number: spend per estimated engineering hour.

Thank you to everyone who joined our September town hall. We covered security updates, stability updates, and new features in the product, including OCR running on Rust by default and test coverage past the 80% target we set in August.

TypeSafe AI's Jev launches on LiteLLM today in v1.103.0-rc. Jev is a decision model: it returns a choice, a score, or a yes/no probability instead of text, so it has its own evaluate endpoint rather than /chat/completions. LiteLLM proxies that endpoint with logging and cost tracking.

A bot looks up the weather, then checks a shop's opening hours. The user asks, "What time does the shop close?" The bot still sends the old weather report to the model, even though it no longer helps answer the question.

TypeSafe Jev helps LiteLLM spot tool results that are no longer needed. LiteLLM replaces those results with a short notice before calling the model. This is called compaction, and it can reduce the input tokens used by long conversations.

Shared agents can preserve individual identity, access, and spend controls.

When a finance agent serves multiple business units, platform teams need a consistent way to identify who initiated each request, apply the right model and tool permissions, and attribute spend. LiteLLM keeps this context available across shared-agent workflows so each business unit can operate under its own access and budget policies.

LiteLLM provides one control plane for this workflow across the Agent Gateway, Model Gateway, and MCP Gateway. Teams can share the same agent infrastructure while keeping access, credentials, spend, and audit data tied to the right caller.

Heuristic v1 scores seven prompt signals, including reasoning language, code, technical terms, and prompt length. You can tune those signals for the traffic your router serves.

Heuristic v2, LiteLLM's new AutoRouter classifier, is up to 45% more efficient than Heuristic v1: more tasks solved, at lower cost, in less time. Only the classifier changed.

Thank you to everyone who joined our August town hall. We used it to share this month's security and stability work and our latest product updates: 79 security fixes, 375 bug fixes, and 142 feature commits, a new Director of Security, a public status dashboard, and Auto-Router results from production.

v1.97 makes three changes to the auto router.

• The LLM classifier now receives a window of prior conversation turns, defaulting to three. This improves accuracy of follow-up classifications from 14% to 78%, costs at most $0.61 per 1,000 requests, and no additional latency.
• A new Benchmarks view prices routed traffic against an all-frontier baseline and reports the difference, and those savings now also appear in the Cost Optimization totals.
• Session affinity is now off by default, following our previous post showing this was leading to worse quality without cost improvements.

Thank you to everyone who joined our July town hall. We used it to share this month's security and stability work and our latest product updates: 38 security fixes, 317 bug fixes, and 140 feature commits, headlined by new Rust benchmarks and the launch of Autorouter V2.

Router plugins are now available on LiteLLM. Each plugin receives the routing context, enriches it, and hands it to the next before the router makes the final decision.

The push came from the autorouter discussion (#32168): teams wanted to layer their own signals (language detection, domain classification, tenant policy, budget caps) onto routing without waiting for each one to land in core. This plugin extension lets teams make these changes while keeping LiteLLM's routing core stable.

Auto Router v2 collapses complexity, semantic, and adaptive routing into a single auto_router/complexity_router. One config now covers heuristic scoring, LLM classification, lexical or semantic keyword rules, and Thompson-sampled tier pools.

The push came from the community. On discussion #32168, users pointed out that all three routing strategies should converge into a single Auto Router. One router with configurable signals and weights keeps the API simple while letting the routing engine evolve internally, instead of forcing you to pick a mode up front.

The operational half came from discussion #32172: predictable beats clever for debuggability. A fixed, versioned mapping from capability class to model is what makes "why did this response cost 4x today" answerable after the fact.

Over the last two weeks we addressed two major product quality issues:

1. The MCP Gateway did not have a single class for credential resolution.
2. Pass-through APIs had high memory consumption.

Across the same window we shipped 134 bug fixes in total. This post covers the two big changes first, then the rest of the AI Eng and reliability work, the full breakdown, and what we are doing next.

Thank you to everyone who joined our June town hall.

Three numbers capture the month: 24 security fixes, 94 bug fixes, and 78 feature commits. The sections below break each one down, alongside our public commitment to zero reported regressions and the gradual migration of the LiteLLM gateway to Rust.

Harnesses are the next frontier of vendor lock-in. LiteLLM was built to swap across model providers easily. However, as the models get saturated, the next area for competition becomes the harnesses and managed agents. To make it easy to go across vendors at the harness layer, we're launching the Lite-Harness SDK. This is a simple TypeScript+Python SDK which allows developers to change harnesses, like they change models.

Thank you to everyone who joined our May town hall.

We covered security hardening, release versioning changes, new product launches (MCP toolsets, on-behalf-of OAuth), performance wins, and our biggest bet yet, the LiteLLM Agent Platform.

We're introducing the LiteLLM Managed Agents Platform - a simple, self-hosted infrastructure platform for running multiple agents in production.

Thank you to everyone who joined our April town hall.

We used the session to share our CI/CD v2 improvements, product stability work, and what we are prioritizing next across reliability and product roadmap.
