• 2026-10-22 (~4:00 AM ET, MarkTechPost — https://www.marktechpost.com/2026/10/22/ibm-granite-speech-5-0-2b-release/): IBM announced Granite Speech 5.0 2B — a 2-billion-parameter multilingual speech-recognition/translation model under the Apache 2.0 license, with a vendor-cited #2 rank on the Open ASR Leaderboard (5.68% error rate). As of this coverage the model is announced, not confirmed downloadable — weights availability is the thread's first watch. Same day (~3:51 AM ET), IBM Research published a Hugging Face blog on ensemble forecasting with Granite time-series models (https://huggingface.co/blog/ibm-research/granite-timeseries-ensemble-r1) — a technical tutorial suggesting an active open-model cadence. Watch: leaderboard verification, actual weights/hosting terms, whether the Granite line sustains releases.
