# LLM 0.33 Moves the Project to httpx2 > Source: > Published: 2026-08-22 18:20:57+00:00 # LLM 0.33 Moves the Project to httpx2 Simon Willison released LLM 0.33 on August 22, moving the project's HTTP dependency from httpx to httpx2 after a short-term compatibility fix in the prior release. The official GitHub release is a non-prerelease version published at 17:01 UTC, making this a developer-environment update rather than a model announcement. LLM 0.33 was released on August 22, 2026, as the latest stable version of Simon Willison's command-line and Python library for working with language models. The GitHub release record marks version 0.33 as a non-prerelease release, published at 17:01 UTC. ### What changed The release moves the project's HTTP dependency from httpx to httpx2. The first-party release records reviewed for this audit center the update on that HTTP-layer migration, rather than on a new model or provider launch. The change follows a short-term compatibility response in LLM 0.32.1. Documentation for that August 21 release says fresh installations had stopped working without an additional httpx dependency, so it temporarily constrained the supported OpenAI Python versions to those below 3.0.0. Version 0.33 replaces that temporary dependency arrangement with the httpx2 migration. ### Why the update matters This is primarily a developer-environment update. Teams that package LLM into applications, container images, reproducible notebooks, or plugin workflows should test an upgrade in the environments they actually ship. Dependency changes can show up first in lockfiles, build pipelines, or extensions that make assumptions about the previous HTTP client. A clean installation and the model paths that matter to a deployed workflow are useful checks after an upgrade. That is a verification recommendation, not a claim that the release will break every integration: the first-party records establish the dependency migration, while each downstream environment has its own lockfiles, wrappers, and plugin set. The release record supports the dependency transition itself. It does not establish that every downstream integration will require changes, so maintainers should validate their own environments rather than infer a universal migration outcome from the version number alone. ## Key Points - 1LLM 0.33 was published on GitHub on August 22, 2026, as a non-prerelease release. - 2The release moves the LLM project's HTTP dependency from httpx to httpx2. - 3LLM 0.32.1 used a temporary OpenAI-version constraint to restore fresh installation behavior. ## Scoring Rationale A stable-release dependency migration affects LLM users and maintainers, especially in reproducible environments, but is narrower in practitioner impact than a new model, security incident, or platform-wide API change. ## Sources Primary source and supporting public references used for this report.
