Claude Haiku 4.5
VerifiedEfficient multimodal model for text, image, and file tasks.
About Claude Haiku 4.5
Claude Haiku 4.5 integrates text, image, and file processing in a single multimodal system. Its 200,000-token context window enables coherent handling of lengthy combined inputs. As a proprietary model from Anthropic, it emphasizes controlled API access rather than open weights.
The design prioritizes efficiency across modalities while maintaining broad input compatibility. Strengths include seamless multi-format analysis without separate preprocessing steps. Typical usage covers document review with visuals, mixed-media content creation, and file-based research queries.

Quick start
OpenRouter's API is OpenAI-compatible — most SDKs work by just swapping the base URL. Only the model slug changes between models.
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://openrouter.ai/api/v1",
apiKey: process.env.OPENROUTER_API_KEY,
});
const completion = await client.chat.completions.create({
model: "anthropic/claude-haiku-4.5",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message.content);Model slug: anthropic/claude-haiku-4.5
