ThursdAI — the weekly AI news podcast hosted by Alex Volkov — has covered 3 Together AI releases since Apr 2025, most recently Series C on Jul 1, 2026. Highlights include DeepCoder-14B-Preview, Series C, Parcae. 1 of them shipped with open weights. Every entry below has primary-source links and the episode segment where we covered it live, plus key numbers where we have them.
Together AI raises $800M Series C at an $8.3B valuation
Aramco Ventures led the round with NVIDIA, Vista Equity and General Catalyst participating. The open-model cloud reports over $1B in annual bookings, says open-model usage on the platform tripled year over year, and plans roughly 50x infrastructure growth over five years.
Parcae: stable looped transformer matches a model twice its size
Together AI and UCSD researchers introduced Parcae, a stable architecture for looped language models that comes with scaling laws and matches the quality of a transformer twice its size. Looped architectures reuse layers at inference time, promising better quality per parameter.
DeepCoder-14B: open RL-finetuned coder beats DeepSeek R1 and o3-mini on coding
Together AI and Agentica (UC Berkeley Sky Computing Lab) released DeepCoder-14B-Preview, a reasoning model finetuned with RL that beats DeepSeek R1 and even o3-mini on several coding benchmarks. The project aims to democratize RL: the team open-sourced the model, the training dataset, the Weights & Biases logs, and the eval logs. Guest Michael Luo from Agentica joined the show to discuss the release.
