LLM Gatewayfree tier▲296I built an OpenAI-compatible LLM gateway that routes requests to OpenAI, Anthropic, Ollama, vLLM, llama-server, SGLang... anything that speaks /v1/chat/completions. Single Go binary, one YAML config file, no infrastructure. It does the things you'd expect from this kind of gateway... semantic routing via a three-layer cascade (keyword heuristics, embedding similarity, LLM classifier) that picks the best model when clients omit the model field, weighted round-robin load balancing across local inference servers with health checks and failover. The part I think is most…

I spent a few hours last weekend testing whether AI can replace code by executing directly. Built a contact manager where every HTTP request goes to an LLM with three tools: database (SQLite), webResponse (HTML/JSON/JS), and updateMemory (feedback). No routes, no controllers, no business logic. The AI designs schemas on first request, generates UIs from paths alone, and evolves based on natural language feedback. It works—forms submit, data persists, APIs return JSON—but it's catastrophically slow (30-60s per request), absurdly expensive ($0.05/request), and has zero UI…

Sudo AI▲265Sudo — AI monetization infrastructure for developers 4 months ago, I kept running into the same problem building AI products: inference is expensive, subscriptions are blunt, and ads weren’t designed for generated content. So I started working on Sudo, an infrastructure layer that makes it easier to launch and monetize AI apps. ⸻ Key features (in beta now): • One API to route across top models (no vendor lock-in) • Real-time metering & billing (usage-based, subscriptions, or hybrid) • Optional AI-native ads — contextual, developer-defined, and personalized • Dashboard for tracking usage,…

We built any-llm because we needed a lightweight router for LLM providers with minimal overhead. Switching between models is just a string change : update "openai/gpt-4" to "anthropic/claude-3" and you're done. It uses official provider SDKs when available, which helps since providers handle their own compatibility updates. No proxy or gateway service needed either, so getting started is pretty straightforward - just pip install and import. Currently supports 20+ providers including OpenAI, Anthropic, Google, Mistral, and AWS Bedrock. Would love to hear what you think!

Dev tool that worries about your LLM API failures.

Hi HN, We’re building https://www.switchpoint.dev – a drop-in replacement for OpenAI’s API that reduces LLM cost by smartly routing across models (e.g., Claude, Gemini, GPT-4) depending on subject and difficulty of the task. Why we built this: LLM costs are spiraling—especially for products doing retrieval, agentic reasoning, or even just high-volume chat. We were frustrated with paying GPT-4 rates when most queries didn’t need it. So we built a router that: - Starts with cheaper/free models (like Llama 8B, 4o-mini, 2.0 flash) - Streams responses and upgrades on failure - Acts…

Author here. Since the last post, RelayFreeLLM now supports NVIDIA's free catalog, adds 4-mode context management (with extractive summarization that doesn't need an LLM), session affinity, output normalization, and a global provider lock to eliminate 429 errors entirely. 8 providers, one endpoint, all free: https://github.com/msmarkgu/RelayFreeLLM
