Models

​

Overview

Zencoder has a model selector in the chat input. Use the dropdown to pick which LLM runs your messages. The options you see depend on your plan and entitlements.

• Model choices may differ by plan; higher plans unlock additional models
• Select the model that fits your task from the selector

Zencoder supports models from OpenAI, Anthropic, Google, and xAI.

​

Available models (subject to change)

The Auto model routes across a tuned mix of self-hosted and vendor models for the best balance of speed, quality, and cost. Lowest multipliers: Grok Code Fast 1 (0.25×), Auto (1×). All multipliers and model availability are subject to change. Model availability evolves over time. We may add, remove, or upgrade models without notice as providers change capabilities and pricing. Your selector will always reflect the currently supported set for your plan.

​

Cost multipliers and credits

Zencoder measures usage in credits. Some models use a multiplier to reflect provider costs or parallel reasoning. See the table above and the screenshot for current multipliers.

​

Plan-based availability

Not all plans have access to all models. The selector shows what your current plan can use. If you recently upgraded but don’t see expected options, restart your IDE to refresh entitlements.

• Pro, Pro Plus, and Pro Max plans: Full model selector with all available models
• Free plan: Access to Auto, Gemini Flash 3.0, and Grok Code Fast 1

​

Bring Your Own Key (BYOK)

You can use your own API key for certain providers. This is useful if you:

• Want to bypass credit consumption for those requests
• Prefer billing directly with the provider

Supported providers in the UI today: Anthropic and OpenAI.

When to switch models

• Use the Auto model for most coding tasks - it balances speed, quality, and cost
• Use the Auto+ for superior performance on complex tasks (2.5× multiplier)
• Use Haiku 4.5 for a fast and cost-efficient option (1× multiplier)
• Use Grok Code Fast 1 when you need the most cost-efficient option (0.25× multiplier)
• Use GPT-5.4-mini for cost-efficient code generation (1.25× multiplier)
• Use Gemini Pro 3.1 for high-quality performance with balanced capability (2× multiplier)
• Use Sonnet 4.6 for spec-driven development tasks requiring persistent state tracking and parallel execution
• Use GPT-5.5 for specialized code generation tasks (Pro Plus and Pro Max plans, 5× multiplier)
• Use Opus 4.6 for challenging tasks requiring high capability (Pro Plus and Pro Max plans, 5× multiplier)
• Use Opus 4.7 (Pro Plus and Pro Max plans) for the most complex reasoning tasks, keeping the 5× multiplier in mind
