Groq is retiring llama-3.1-8b-instant, llama-3.3-70b-versatile, qwen3-32b and llama-4-scout-17b, recommending migration to gpt-oss-20b/120b or qwen3.6-27b. Enterprise committed-spend contracts are exempt. If your stack pins these model IDs, schedule the migration now.
Ollama's install base doubled year-over-year as privacy-sensitive teams standardize on local inference for development and internal tooling.
