# Technical Challenges and Development
Developers working with ElizaOS v2 have ...
encountered several technical challenges:
1. **Plugin Integration Issues**: Users reported difficulties with SQL plugin compatibility, database connections, and plugin registration. The v2 version requires using the elizaos command to actively download plugins.
2. **Model Support Limitations**: ElizaOS v2 primarily supports OpenAI and Anthropic models by default, though there are mentions of local-ai, Grok/Groq, and Ollama as alternatives.
3. **Auto.fun Platform Issues**: The platform experienced downtime for upgrades, with team members describing the technical challenges as a "hydra" where solving one issue reveals additional problems. Issues included tokens stuck in migration, creation failures where SOL was taken but tokens weren't properly registered, and fee claiming errors.
Development teams are actively working on resolving these issues, with regular updates being provided through Discord and Twitter.
