Error message

Dify Hosted OpenAI trial currently not support the GPT-4 model.

What it means

HTTP 400 ProviderModelCurrentlyNotSupportError, raised by the STT endpoint. The model layer raised ModelCurrentlyNotSupportError: the selected model is not available under the tenant's current plan/provider tier. The canned message references the GPT-4 trial restriction as the canonical example, but it fires for any model the provider refuses to serve on the current plan.

Solutions

Switch the default speech2text model to one supported by the current plan (Settings -> Model Provider).
Upgrade the plan or supply your own provider credentials that entitle the desired model.
If a model was deprecated, select the provider's recommended replacement.

Defensive patterns

Strategy: validation

Validate before calling

// After fetching available models for the tenant, confirm the default STT model is entitlement-eligible.
if (!availableModels.some(m => m.model_type === 'speech2text' && m.status === 'active')) warnUser()

Try / catch

try { await postAudio(file) }
catch (e) { if (e.code === 400 && e.error_code === 'model_currently_not_support') promptSwitchModel() else throw e }

Prevention

Keep the default STT model on a provider/plan that entitlements it.
After a plan change or provider deprecation, re-select a supported default model.
Subscribe to provider deprecation notices.

When it happens

Trigger: POST /console/explore/installed-apps/{id}/audio-to-text where the default speech2text model resolves to one the tenant's plan does not entitlement (e.g., a premium Whisper variant on a trial tier, or a gated model the provider disabled for this account).

Common situations: Trial workspace pointing at a gated model; provider deprecated/disabled a model between calls; plan downgrade removed access to the configured model.
