AI Models
Avi ships its own catalog of top-tier models. You don't bring your own API key — Avi is the provider, and usage consumes credits at published per-model rates. See Billing.
Catalog
| Model | Best for |
|---|---|
| Claude Sonnet 5 | The default. Balanced reasoning and speed. Works well for almost everything. |
| Claude Sonnet 5.5 | The newest Sonnet: an upgrade over Sonnet 5 at the same credit rate, and faster. Balanced reasoning and speed. |
| Claude Opus 5.5 | Hardest problems. Long-running coding and knowledge work, complex reasoning, high stakes; reports back clearly on what it did. Uses more credits per token. |
| Claude Haiku 5.5 | Fast, cheap, light tasks. Good for quick lookups or high-volume work. |
| OpenAI GPT-5.6 Sol | OpenAI's flagship for ambitious agentic work. |
| OpenAI GPT-5.6 Terra | Balanced OpenAI model for efficient, high-volume work. |
| OpenAI GPT-5.6 Luna | Fast, affordable OpenAI model for everyday work. |
| OpenAI GPT-6 Astra | OpenAI's most capable model. The hardest end-to-end reasoning, coding, and research work. Costs the most per token. |
| OpenAI GPT-6 Sol | OpenAI's daily model for complex coding and agentic workflows. GPT-6 intelligence at a fraction of Astra's price. |
| OpenAI GPT-6.1 Sol | The upgraded GPT-6 Sol: close to Astra on coding, computer use, and professional work at about a fifth of Astra's price. |
| OpenAI GPT-6 Luna | OpenAI's most efficient GPT-6. Summarization, extraction, classification, routing — high volume, very cheap. |
| GLM 5.3 Flash | Frontier open-weight reasoning at a fraction of the cost. Fast, very cheap. |
| GLM 5.3 | Z.ai's open-weight flagship. Stronger reasoning than Flash, still affordable. |
| GLM 5.3 Fast | GLM 5.3 on dedicated capacity for higher sustained throughput. Same reasoning, faster. |
| DeepSeek Flash 4.1 | DeepSeek's newer Flash generation. Cheap, fast, for high-volume everyday work. |
| Kimi K3 | Moonshot's open-weight flagship. Deep reasoning and long-horizon agentic work. |
Picking a model
- Start with Sonnet. It's the right call most of the time.
- Upgrade to Opus when a task is hard, multi-step, or the stakes are high enough that you'd want a second opinion.
- Drop to Haiku when you want fast and cheap — short summarizations, quick lookups, automation.
- Try GPT-5.6 Sol for advanced coding, research, and long-running agentic work.
- Audio or video? Use a Claude or GPT model. The open-weight models (GLM, DeepSeek, Kimi) read text and images, including images from your files, but not audio or video. PDFs work on every model: Avi reads their text and looks at their pages as pictures. When a model opens a file it can't read, it tells you so.
Where to set the model
- Org-level default — in org settings. Every project in the org picks this up unless overridden.
- Per-project — override in project settings. Lets you use Opus for your most demanding project while keeping Sonnet everywhere else.
Voice turns use the project's configured chat model too — speaking to the agent and typing to it go to the same model.
Background work
Some of Avi's work happens without you asking: sorting events into your feed, summarizing long conversations, telling whether a second thing you said finishes the first, and app chores like labeling a new task. All of it runs on GLM 5.3 Flash, whatever chat model you pick, and it's billed at GLM 5.3 Flash's rates. The updates in your feed are then written by Claude Sonnet 5.5.
If your org's Allowed models list leaves out GLM 5.3 Flash, that background work pauses, feed updates included, until an owner or admin allows it again. Leaving out Claude Sonnet 5.5 pauses the feed's updates the same way. Your chats and automations keep using the models you allowed.
