Expected August–September 2026
DeepSeek V4-Pro — official GA
1.6T parameter flagship. Confirmed "coming soon" in DeepSeek's July 31 changelog. No date published. Preview available via API now. V4 Flash 0731 already outperforms V4-Pro-Preview on agent benchmarks — the GA Pro will need to justify its higher price tier.
Qwen3.8-Max — open weights and GA
Alibaba promised open weights "soon" at the July 19 WAIC announcement. No Hugging Face repository exists as of August 6. No GA date, no confirmed per-token pricing, no license published. Kimi K3 shipped weights on day 11. Qwen3.8 is on day 18 with no update.
OpenAI IPO — public S-1 and listing
Not a model release but the defining capital event of August 2026. Confidential S-1 filed May 22. Public prospectus expected mid-to-late August. September listing target. Goldman Sachs, Morgan Stanley, JPMorgan leading. For information only, not investment advice.
Google Gemini 3.6 Pro / Ultra — unconfirmed
No announcement from Google. Gemini 3.6 Flash launched July 21 — Pro and Ultra variants in the same generation would follow the same pattern as Gemini 3.5 (Flash → Pro → Ultra). No timeline published.
Meta Llama 4 follow-up variants — unconfirmed
Llama 4 Scout and Maverick launched April 2026. No announcement on follow-up variants. Meta's pattern with Llama 3 suggests additional model sizes (70B, 405B equivalents) and fine-tuned variants would follow the initial launch by 3-6 months — putting potential releases in Q3-Q4 2026.

How We Track AI Model Releases
This tracker is updated manually each day as part of our daily AI news coverage. We source from official lab announcements, API changelogs, and verified third-party trackers including LLM Gateway, AI Release Tracker, and Evertune. We do not add models to the "released" table until pricing, model string, and availability are confirmed from the official source. Preview or rumoured models go in the "In Preview" section with what is still missing clearly noted.
