Parsaa supports models from multiple providers. The available list is served live and kept up to date, so new models appear without an app update. Switch models any time in Settings → Models → Chat Models, or from the model picker in the composer.

Providers

ProviderNotes
AnthropicClaude family models

GoogleGemini family models
OpenRouterA single key for 100+ models across providers — see OpenRouter
LocalOn-device models via LM Studio, Ollama, or any OpenAI-compatible server — see Local Models
Because the catalog is dynamic, the exact model names you see in Chat Models reflect what’s currently offered for your plan. Use the picker in the app as the source of truth.

​
Reasoning Effort

For models that support it, you can set how much the model “thinks” before responding. Higher effort trades speed for depth.
EffortDescription
MinimalLightest reasoning, fastest response
LowLight reasoning
MediumBalanced default
HighMore deliberate reasoning
Extra HighDeepest reasoning
Available levels depend on your plan:
PlanReasoning levels
FreeLow, Medium
ProMinimal, Low, Medium, High
Lite / EliteAll five (Minimal → Extra High)
Set the effort from the composer before sending. Toggle the visible thinking display from the chat footer to watch the model reason in real time.

​
Choosing a Model

A fast model at Low or Medium effort — ideal for simple questions, small edits, and exploration.
A strong coding model at Medium or High effort — better at large codebases and multi-file changes.
A frontier model at High or Extra High effort — best for architecture decisions and intricate debugging.
A Local model — all inference runs on your Mac with no network calls. See Local Models.
