A developer with over a year of production AI agent experience published a FastAPI and OpenAI SDK implementation pattern covering the core request loop, function-calling tool use, and Redis-backed sta…
A developer released Charter, an open-source Python library that lets developers declare AI agent tools as Pydantic models instead of writing integration code, shipping with 549 tools across fifteen A…
A developer built VirgoFash, an open-source, zero-dependency asynchronous Python search library that relies only on asyncio and httpx to fetch real-time web results without blocking the event loop. Th…
A developer built findmypylibrary, a Python CLI tool that answers "I need to do X in Python, which package?" by ranking packages from a 15,000-row PyPI download dataset. The tool fetches package summa…
A technical guide outlines a resilient Python web-scraping architecture that splits work into discovery, extraction, and validation stages, using progressive extraction that tries a standard HTTP requ…
A developer has outlined a self-healing web scraping architecture that uses an LLM only as a fallback when hardcoded CSS selectors break, rather than for every request. The approach validates extracte…
A developer published a load-based exit test for teams running agent backends on free-tier endpoints, arguing that free capacity fails quietly as latency, retries, and queue debt rather than through o…
Anthropic shipped Python SDK v1.0.0 on August 20 with six breaking changes, including swapping the httpx transport layer for the Pydantic-maintained httpx2, which silently breaks tracing libraries, AP…
A new Python library called litelm extracts the core routing and message-translation functionality of litellm into roughly 2,900 lines of code with just 2 dependencies, openai and httpx, dropping the …
A developer has open-sourced fastapi-multi-llm-starter, an MIT-licensed FastAPI template that unifies streaming access to multiple LLM providers including Anthropic, Google, OpenAI, and DeepSeek behin…
A developer migrating an MCP server and two clients from FastMCP 3 to FastMCP 4 documented several breaking changes that compile but fail at runtime. Key issues include a pip in-place upgrade leaving …
OpenAI's Python SDK now uses HTTPX2 for its synchronous and asynchronous HTTP clients, replacing the previous httpx package, which is no longer installed automatically. The migration changes the defau…
A developer has published a step-by-step tutorial for building a token-budgeted LLM service that runs on a free server. The service, built with Python and the httpx library, tracks token usage and fai…
Simon Willison released LLM 0.33 on August 22, 2026, as a non-prerelease version, moving the project's HTTP dependency from httpx to httpx2. The update follows a temporary compatibility fix in LLM 0.3…
An engineer detailed a queue-first architecture that turns free-tier LLM quotas into batch engines, using a SQLite-backed task queue and Python workers to achieve ten times the throughput of synchrono…
Simon Willison released LLM 0.32.1 on Aug. 21, pinning the OpenAI Python dependency below version 3.0.0 to ensure fresh installations work without a separate httpx install. The maintenance update addr…
LLM 0.32.1, a dot-release of the command-line tool for running AI models, fixes broken fresh installs caused by the OpenAI Python library dropping its usage of httpx, which LLM depended on transitivel…
A developer built Argentic, a Go-based reverse proxy that charges AI scrapers per request using Lightning Network payments via L402 credentials, returning a 402 Payment Required with a Bitcoin Lightni…
A developer building a distributed AI workflow with Groq, Streamlit Cloud, and Supabase reports that connection drops, such as httpx.ConnectError, caused a 'Red Screen of Death' in their admin dashboa…
A 16-year-old developer building Lawyie, a legal tech platform under Sunverse AI, encountered an httpx.ConnectError in the admin dashboard, prompting a defensive coding approach to handle distributed …
