Open-weight LLM release cycles show six-week gap; next cluster forecast for late May
A community-charted timeline of major open-weight LLM releases over the past year projects the next cluster for late May to early June, but the longest gap yet is raising questions about whether the cadence is shifting.
A timeline chart mapping major open-weight releases over the past twelve months projects the next cluster to arrive between late May and early June, based on historical spacing of four to six weeks. The chart plots releases from Meta, Mistral, Alibaba, and DeepSeek, showing five distinct clusters over the period — but the current gap is stretching longer than usual, prompting speculation that the open-weight release rhythm may be changing.
The scatter plot marks notable recent releases including Llama 3.3, Qwen 2.5, and DeepSeek R1 in early April, followed by a visible dry spell extending into mid-May. Based on the 28–42 day spacing between previous clusters, the projection lands around May 25–June 5. The chart carries no vendor confirmations or leaked roadmaps — it is a pure extrapolation from historical patterns.
What stands out
- 01Consistent four-to-six-week cycles. Five distinct release clusters over the past year, each separated by roughly 28–42 days. The most recent cluster was in early April, placing late May at the expected window for the next wave.
- 02No single vendor controls the calendar. Meta, Mistral, Alibaba, and DeepSeek all appear multiple times across clusters, but their releases don't align — suggesting independent roadmaps rather than coordinated scheduling.
- 03The current gap is the longest on record. At nearly six weeks, the dry spell sits at the upper bound of historical spacing. The observation that "something's changing" reflects growing concern the pattern may be breaking.
- 04No confirmed releases validate the forecast. The projection is backward-looking only; there are no announcements or leaked timelines to anchor the late-May window.
