Screenshot of doesjitgobrrr.com dashboard showing JIT benchmark results for Python 3.15.0a8+ on April 18, 2026. Four machine cards summarize geometric mean results across 119 benchmarks: blueberry (aarch64) same speed, jones (aarch64, tail calls) 13.0% faster, prometheus (x86_64, tail calls) 6.0% faster, ripley (x86_64) 8.0% faster. Below, the Compare tab shows a cross-machine comparison table filtered by "fastapi", with fastapi_http benchmark results: 1.01x faster on blueberry, 1.13x faster on jones, 1.02x faster on prometheus, and 1.06x faster on ripley.

Limit candidate packages to those that were uploaded prior to the given date. Accepts RFC 3339 timestamps (e.g., 2006-12-02T02:07:43Z), local dates in the same format (e.g., 2006-12-02) resolved based on your system's configured time zone, a "friendly" duration (e.g., 24 hours, 1 week, 30 days), or an ISO 8601 duration (e.g., PT24H, P7D, P30D). Durations do not respect semantics of the local time zone and are always resolved to a fixed number of seconds assuming that a day is 24 hours (e.g., DST transitions are ignored). Calendar units such as months and years are not allowed. May also be set with the UV_EXCLUDE_NEWER environment variable.

We’ve read your posts and heard your feedback. 1. We’re postponing the announced billing change for self-hosted GitHub Actions to take time to re-evaluate our approach. 2. We are continuing to reduce hosted-runners prices by up to 39% on January 1, 2026. We have real costs in running the Actions control plane. We are also making investments into self-hosted runners so they work at scale in customer environments, particularly for complex enterprise scenarios. While this context matters, we missed the mark with this change by not including more of you in our planning. We need to improve GitHub Actions. We’re taking more time to meet and listen closely to developers, customers, and partners to start. We’ve also opened a discussion to collect more direct feedback and will use that feedback to inform the GitHub Actions roadmap. We’re working hard to earn your trust through consistent delivery across GitHub Actions and the entire platform.
