Choose the right AI model — not just the most popular one.
Structured model facts, official sources, and clearly identified historical status — so you can decide with confidence, not hype.
How to choose the right AI model
A structured decision path — from problem to deployment.
Define your problem
Start with what you need to build — text generation, code, reasoning, image understanding, audio, or a combination. A clear problem definition narrows the field immediately.
Discover required capabilities
Browse AI models grouped by functional capability. Each capability card shows how many published models support it, so you know what is available before you dig deeper.
Shortlist relevant models
Filter the catalog by provider, deployment type, pricing tier, and capability tags. Surface only the models that match your constraints — context window, open-weights, and local-deployment support included.
Compare structured facts
Use the side-by-side comparison tool to review capabilities, context-window limits, pricing, and lifecycle status together — not from scattered marketing pages.
Verify availability and official sources
Each model record links to its primary provider documentation. Historical status — legacy, deprecated, or superseded — is clearly identified so you do not integrate a model that is no longer maintained.
Choose hosted API or local deployment
Decide between provider-managed cloud APIs and open-weight local deployment. Each path has different hardware, licensing, and operating-cost considerations — Optix AI helps you evaluate both.
Where would you like to start?
Three clear entry points into the model catalog.
I know my requirement
Start with the capability you need — text generation, code, image understanding, reasoning, or multimodal. Browse models grouped by functional capability.
Explore CapabilitiesI know the model names
Jump straight to the model catalog to browse by provider, or open the compare tool to review two to four models side by side.
I want to run AI locally
Explore open-weight models for local or on-premise deployment. Consider model size, your hardware, licensing terms, and runtime requirements before choosing a model to self-host.
Explore Local ModelsBrowse by Capability
Discover AI models structured by core functional capabilities and task domains.
Hosted API or open-weight / local?
Two distinct paths with different trade-offs. Understand both before you decide.
Hosted API
- Provider-managed infrastructure — no server setup required
- Faster integration via documented APIs and SDKs
- Usage-based pricing where available
- Dependent on provider availability, rate limits, and policies
Open-Weight / Local
- Greater deployment control — you own the runtime
- Hardware and runtime responsibility is yours
- Licensing varies — check each model's terms
- Operating cost is not zero — feasibility depends on model size, quantization, and runtime
