Model Tiers
Cognova uses Anthropic's Claude models exclusively. We offer three tiers optimized for different use cases.
Tiers
Fast — Claude Haiku 4.5
- Best for: Quick lookups, simple Q&A, classification, summarization
- Speed: Fastest response times
- Available on: All plans
Haiku is ideal for high-volume, low-complexity tasks. Use it for agents that handle routine queries, format data, or triage incoming requests.
Balanced — Claude Sonnet 4.6
- Best for: Code generation, analysis, detailed explanations, multi-step reasoning
- Speed: Fast with significantly higher capability
- Available on: Starter and above
Sonnet is the best default for most agents. It handles complex reasoning, code review, and nuanced analysis while keeping response times reasonable.
Pro — Claude Opus 4.6
- Best for: Complex architecture decisions, deep analysis, creative writing, research
- Speed: Slower but highest capability
- Available on: Pro and above
Opus is the most capable model. Use it for agents that need maximum intelligence — system design, comprehensive code review, or tasks where quality matters more than speed.
Choosing a Tier
| Scenario | Recommended Tier |
|---|---|
| FAQ bot, data formatting | Fast (Haiku) |
| Code review, bug analysis | Balanced (Sonnet) |
| Architecture planning, deep research | Pro (Opus) |
| High-volume triage | Fast (Haiku) |
| Customer support with nuance | Balanced (Sonnet) |
| Legal/compliance review | Pro (Opus) |
Setting Model Tier
Each agent has its own model tier setting:
- Go to Agents in the sidebar
- Click the agent to edit
- Change the Model Tier dropdown
- Save
The model tier only affects that specific agent. You can mix tiers across agents — use Haiku for your triage agent and Opus for your code reviewer.
Credit Costs
Each message costs credits based on the model tier:
| Tier | Credits per Message |
|---|---|
| Fast (Haiku) | 1 credit |
| Balanced (Sonnet) | 3 credits |
| Pro (Opus) | 5 credits |
Tool calls, web searches, and agent delegation within a single message are included at no extra cost. Detailed usage (including per-agent breakdown and API costs) is visible in Settings > Billing.
