LLM release watchlist
New large language model release tracker for builders
A source-linked tracker for new large language model releases, model API launches, open-weight drops, and benchmark-backed updates. AI Hot turns each public signal into a practical decision: try, watch, compare, save, or skip.

Why it matters
Map model news to cost, latency, eval quality, context window, migration risk, and vendor lock-in before testing.
What to do next
Open the original source, test only with non-sensitive data, and compare against the model already in your stack.

Evaluation checklist
- • Is the release backed by an official source, repo, paper, or credible primary post?
- • Does it change cost, latency, context window, tools/function calling, coding, or multimodal capability?
- • Is access public, waitlisted, paid, open-weight, API-only, or enterprise-only?
- • Can you run a 30-minute non-sensitive test before moving workflow traffic?
