Hosted reasoning, tools, coding, and search-connected workflows.
Strengths
The fast role prioritizes responsiveness and throughput within the family.
Grok 4.20 · non-reasoning snapshot is provider-listed as the fast release in its model family.
Weaknesses
General availability does not guarantee identical capabilities across every product, account, or endpoint.
Verify exact capabilities, pricing, latency, context limits, tools, and regional availability with the provider.
These points are OpenGPT decision guidance derived from provider-confirmed family, catalog role, and lifecycle information. They are not measured results for this exact version. Verify capabilities, pricing, latency, context limits, tools, and regional availability with the provider.

Family limitations
Closed weights and provider-controlled data/tool access. Observed quality depends on the exact model and enabled tools.
Verify the exact version before choosing: capabilities, price, context limits, latency, tools, and regional availability can differ by provider access path.
Provider documentation and OpenGPT catalog classification are labeled separately.
Version differences
Compare two catalog model IDs from one model family. Provider IDs, sources and published ranking signals are shown; OpenGPT catalog classification is labeled separately.
No verified feature-difference data is available. OpenGPT does not infer speed, price, context length, or quality.
