Hacker News with Generative AI: API

Show HN: Open Responses – Self-hosted OpenAI Responses API, works with any model (github.com/julep-ai)
Open Responses lets you run a fully self-hosted version of OpenAI's Responses API. It works seamlessly with any large language model (LLM) provider—whether it's Claude, Qwen, Deepseek R1, Ollama, or others. It's a fully-compatible drop-in replacement for the official API. Swap out OpenAI without changing your existing Agents SDK code.

Why PostgreSQL needs a better API for alternative table engines? (orioledb.com)
For a long time now, PostgreSQL has had an extensible Index Access Method API (called AM), which has stood the test of time and enabled numerous robust extensions to provide their own index types. For example: rum, pgvector, bloom, zombodb and others. PostgreSQL 12 introduced the Table AM API, promising equivalent flexibility for table access methods.

Bundling MCP Servers in Every OpenAPI –> TypeScript SDK (speakeasy.com)
It’s no longer enough for businesses to make their services available to developers. A great development experience also hinges on the ability for AI to access and integrate with available APIs. That’s why starting today, every TypeScript SDK generated by Speakeasy now bundles a runnable Model Context Protocol (MCP) (opens in a new tab) server enabling you to expose your API to the growing landscape of AI agents.

Great software design looks underwhelming (seangoedecke.com)
Years ago I spent a lot of time reviewing coding challenges. The challenge itself was very straightforward - building a CLI tool that hit an API and allowed the user to page through and inspect the data. We allowed any language, so I saw all kinds of approaches1. At one point I came across a challenge I thought was literally perfect.

How (not) to sign a JSON object (2019) (latacora.com)
Last year we did a blog post on interservice auth. This post is mostly about authenticating consumers to an API. That’s a related but subtly different problem: you can probably impose more requirements on your internal users than your customers. The idea is the same though: you’re trying to differentiate between a legitimate user and an attacker, usually by getting the legitimate user to prove that they know a credential that the attacker doesn’t.

Scaling LLMs with Golang: How we serve millions of LLM requests (assembled.com)
While the LLM ecosystem is overwhelmingly Python-first, we've found Go to be exceptionally well-suited for production deployments. Our Go-based infrastructure handles millions of monthly LLM requests with minimal performance tuning. Beyond Go's well-documented advantages (see Rob Pike’s excellent distillation of Go's benefits), three capabilities have proven particularly valuable for LLM workloads: static type checking for handling model outputs, goroutines for managing concurrent API calls, and interfaces for building composable response pipelines.
