--- title: AI Models and Pricing - Zed description: AI models available via Zed Pro including Claude, GPT-5.2, Gemini 3.1 Pro, and Grok. Pricing, context windows, and tool call support. --- # Models Zed's plans offer hosted versions of major LLMs with higher rate limits than direct API access. Model availability is updated regularly. To use your own API keys instead, see [LLM Providers](./llm-providers.md). For general setup, see [Configuration](./configuration.md). | Model | Provider | Token Type | Provider Price per 1M tokens | Zed Price per 1M tokens | | ---------------------- | --------- | ------------------- | ---------------------------- | ----------------------- | | Claude Opus 4.5 | Anthropic | Input | $5.00 | $5.50 | | | Anthropic | Output | $25.00 | $27.50 | | | Anthropic | Input - Cache Write | $6.25 | $6.875 | | | Anthropic | Input - Cache Read | $0.50 | $0.55 | | Claude Opus 4.6 | Anthropic | Input | $5.00 | $5.50 | | | Anthropic | Output | $25.00 | $27.50 | | | Anthropic | Input - Cache Write | $6.25 | $6.875 | | | Anthropic | Input - Cache Read | $0.50 | $0.55 | | Claude Sonnet 4.5 | Anthropic | Input | $3.00 | $3.30 | | | Anthropic | Output | $15.00 | $16.50 | | | Anthropic | Input - Cache Write | $3.75 | $4.125 | | | Anthropic | Input - Cache Read | $0.30 | $0.33 | | Claude Sonnet 4.6 | Anthropic | Input | $3.00 | $3.30 | | | Anthropic | Output | $15.00 | $16.50 | | | Anthropic | Input - Cache Write | $3.75 | $4.125 | | | Anthropic | Input - Cache Read | $0.30 | $0.33 | | Claude Haiku 4.5 | Anthropic | Input | $1.00 | $1.10 | | | Anthropic | Output | $5.00 | $5.50 | | | Anthropic | Input - Cache Write | $1.25 | $1.375 | | | Anthropic | Input - Cache Read | $0.10 | $0.11 | | GPT-5.2 | OpenAI | Input | $1.25 | $1.375 | | | OpenAI | Output | $10.00 | $11.00 | | | OpenAI | Cached Input | $0.125 | $0.1375 | | GPT-5.2 Codex | OpenAI | Input | $1.25 | $1.375 | | | OpenAI | Output | $10.00 | $11.00 | | | OpenAI | Cached Input | $0.125 | $0.1375 | | GPT-5 mini | OpenAI | Input | $0.25 | $0.275 | | | OpenAI | Output | $2.00 | $2.20 | | | OpenAI | Cached Input | $0.025 | $0.0275 | | GPT-5 nano | OpenAI | Input | $0.05 | $0.055 | | | OpenAI | Output | $0.40 | $0.44 | | | OpenAI | Cached Input | $0.005 | $0.0055 | | Gemini 3.1 Pro | Google | Input | $2.00 | $2.20 | | | Google | Output | $12.00 | $13.20 | | Gemini 3 Flash | Google | Input | $0.30 | $0.33 | | | Google | Output | $2.50 | $2.75 | | Grok 4 | X.ai | Input | $3.00 | $3.30 | | | X.ai | Output | $15.00 | $16.5 | | | X.ai | Cached Input | $0.75 | $0.825 | | Grok 4 Fast | X.ai | Input | $0.20 | $0.22 | | | X.ai | Output | $0.50 | $0.55 | | | X.ai | Cached Input | $0.05 | $0.055 | | Grok 4 (Non-Reasoning) | X.ai | Input | $0.20 | $0.22 | | | X.ai | Output | $0.50 | $0.55 | | | X.ai | Cached Input | $0.05 | $0.055 | | Grok Code Fast 1 | X.ai | Input | $0.20 | $0.22 | | | X.ai | Output | $1.50 | $1.65 | | | X.ai | Cached Input | $0.02 | $0.022 | ## Recent Model Retirements As of February 19, 2026, Zed Pro serves newer model versions in place of the retired models below: - Claude Opus 4.1 → Claude Opus 4.5 or Claude Opus 4.6 - Claude Sonnet 4 → Claude Sonnet 4.5 or Claude Sonnet 4.6 - Claude Sonnet 3.7 (retired Feb 19) → Claude Sonnet 4.5 or Claude Sonnet 4.6 - GPT-5.1 and GPT-5 → GPT-5.2 or GPT-5.2 Codex - Gemini 2.5 Pro → Gemini 3.1 Pro - Gemini 3 Pro → Gemini 3.1 Pro - Gemini 2.5 Flash → Gemini 3 Flash ## Usage {#usage} Any usage of a Zed-hosted model will be billed at the Zed Price (rightmost column above). See [Plans and Usage](./plans-and-usage.md) for details on Zed's plans and limits for use of hosted models. > LLMs can enter unproductive loops that require user intervention. Monitor longer-running tasks and interrupt if needed. ## Context Windows {#context-windows} A context window is the maximum span of text and code an LLM can consider at once, including both the input prompt and output generated by the model. | Model | Provider | Zed-Hosted Context Window | | ----------------- | --------- | ------------------------- | | Claude Opus 4.5 | Anthropic | 200k | | Claude Opus 4.6 | Anthropic | 1M | | Claude Sonnet 4.5 | Anthropic | 200k | | Claude Sonnet 4.6 | Anthropic | 1M | | Claude Haiku 4.5 | Anthropic | 200k | | GPT-5.2 | OpenAI | 400k | | GPT-5.2 Codex | OpenAI | 400k | | GPT-5 mini | OpenAI | 400k | | GPT-5 nano | OpenAI | 400k | | Gemini 3.1 Pro | Google | 200k | | Gemini 3 Flash | Google | 200k | > Context window limits for hosted Gemini 3.1 Pro/3 Pro/Flash may increase in future releases. Each Agent thread in Zed maintains its own context window. The more prompts, attached files, and responses included in a session, the larger the context window grows. Start a new thread for each distinct task to keep context focused. ## Tool Calls {#tool-calls} Models can use [tools](./tools.md) to interface with your code, search the web, and perform other useful functions.
