AI Roundtable by Opper lets you pose a question and have multiple AI models from different providers debate it simultaneously. You can watch models agree, disagree, and build on each other's arguments in real time. Useful for exploring complex topics where model bias matters.

Onyx is a fully open-source AI platform that brings together chat, agentic RAG, deep research, and custom agents in a single self-hostable application. Unlike cloud-only alternatives, Onyx runs on Docker, Kubernetes, or any major cloud provider, giving teams complete control over their data and deployment. The platform connects to 50+ data sources via indexing connectors and supports every major LLM provider — from self-hosted Ollama models to OpenAI and Anthropic. Its hybrid search combines keyword and vector indexing, while multi-step research agents ranked top on their benchmark as of February 2026. Onyx ships in two editions: a Community Edition (MIT-licensed) covering chat, RAG, agents, and actions, and an Enterprise Edition adding SSO, RBAC, audit logs, and whitelabeling. With nearly 24k GitHub stars and 4k new this week, it's become the de facto open-source alternative to tools like Glean and Guru.
Reviewer scorecard
“Multi-model deliberation is how we will make important decisions in five years. Seeing where models agree gives you real signal — and where they diverge reveals your blind spots. AI Roundtable makes this accessible to anyone right now.”
“Onyx represents a critical counter-movement to AI centralization. As enterprise AI spending scrutiny intensifies, self-hostable alternatives with full data sovereignty will capture the compliance-sensitive markets that hyperscalers are locked out of.”
“Fun demo, questionable utility. Most models are trained on similar data so you get correlated opinions, not independent perspectives. The "debate" is often just paraphrasing. I would rather get one great answer from the best model than 200 mediocre ones.”
“Self-hosting a full AI platform isn't actually free — you're paying in ops overhead, GPU costs, and the engineer-hours to maintain it. The enterprise features that actually matter (SSO, RBAC) are paywalled behind a license that isn't priced publicly, which is a red flag for budget planning.”
“The engineering behind routing to 200+ models in parallel is solid. As a tool for evaluating model capabilities across providers it is genuinely useful — I used it to compare how different models handle ambiguous coding questions before picking my agent's backbone.”
“If you've been paying for Glean or Guru, Onyx is your escape hatch. Self-hosting is straightforward with Docker, and the 50+ connectors cover virtually every data source your team needs. The hybrid search quality is genuinely competitive.”
“For content teams that need AI over their own knowledge base without shipping documents to a third-party cloud, Onyx is a genuine solution. The voice mode and image generation are unexpected bonuses that make it a complete workspace.”
