Model-Agnostic AI Agent Tools

AI agent tools whose own product documentation supports multiple model providers or a bring-your-own-key layer, so the underlying LLM can be swapped without rebuilding the agent.

A model-agnostic AI agent is one whose own listing names multiple model providers or an explicit bring-your-own-key (BYOK) layer, rather than baking in a single vendor's models.

What this collection covers

The set below is the buyers' shortlist when the question is "what runs everywhere": agents whose own product documentation names Claude, GPT, Gemini and at least one open-weight family, and where swapping the underlying model is a configuration change rather than a rewrite.

Per-entry notes name which providers each agent explicitly supports, so the gap between "model-agnostic in name" and "model-agnostic in the listing's own text" is visible at a glance.

How these 20 agents were picked

A tool earns a place here only when its own Published, sourced listing sets `attributes.modelAgnostic` to Yes, meaning the tool's own documentation names multiple model providers (Anthropic, OpenAI, Google, Mistral, Meta, DeepSeek and so on) or exposes an explicit bring-your-own-key layer where any compatible API endpoint can be plugged in. A single named provider with a roadmap promise of more does not qualify. Neither does a vendor's general "we work with all models" marketing claim that does not surface in the listing's own fields. Membership is derived from each listing's already-researched, quality-gated `attributes` and `integrations` data, not from inference about a tool's flexibility. Where a tool's claim to multi-provider support lives only in a third-party blog post or a community report, that is not enough; the listing must surface it in a field the listings lane has already verified.
