How to Access Claude 4 for Free in 2026

Claude 4 (including Opus 4 and Sonnet 4) represents Anthropic's most capable model family, excelling at coding, reasoning, analysis, and creative writing. While the full experience requires a paid subscription, there are several legitimate ways to access Claude 4 models at no cost. This guide covers every method, from the built-in free tier to third-party access points.

Understanding the Claude 4 Model Family

Before diving into free access methods, here is a quick overview of what is available:

Model	Tier	Strengths	Typical Access
Claude Opus 4	Flagship	Best reasoning, coding, analysis	Pro/Max subscription, API
Claude Sonnet 4	Mid-tier	Fast, capable, great value	Free tier, Pro, API
Claude Haiku 4	Lightweight	Speed, cost efficiency	Free tier, API

Sonnet 4 is the default model on the free plan and is genuinely capable -- it handles most tasks well. Opus 4 is the premium model that excels on the hardest problems.

Method 1: Use Claude.ai Free Tier

The most straightforward way to access Claude 4 is through the free tier at claude.ai.

What You Get Free

Go to claude.ai and create an account with your email or Google account.
You are automatically on the free plan.
You get access to Claude Sonnet 4 as your default model.
Limited access to Claude Opus 4 (typically a few messages per day).
Claude Haiku 4 is available for simple tasks.

Free Tier Limits

Feature	Free	Pro ($20/mo)	Max ($100/mo)
Sonnet 4 messages/day	~30-50	~150-250	~600-1,000
Opus 4 messages/day	~5-10	~50-100	~200-400
Extended thinking	No	Yes	Yes
File uploads	5/chat	20+/chat	50+/chat
Projects	Basic	Full	Full
Web search	Limited	Full	Full

The exact message counts vary based on conversation length and server load. Shorter messages with shorter responses allow more messages per day.

Tips to Maximize Free Messages

Keep conversations concise. Long conversations with extensive context use more resources and count more heavily against your limit. Start fresh conversations for new topics.

Ask complete questions. Instead of a series of follow-ups, provide full context in your first message. This gets better answers in fewer messages.

Use the right model. Sonnet 4 handles most tasks well. Save your limited Opus 4 messages for genuinely complex reasoning, math, or multi-step coding problems.

Method 2: Anthropic API Free Credits

New Anthropic developer accounts receive free API credits that you can use to access Claude 4 models programmatically.

Get Started

Visit console.anthropic.com and create a developer account.
New accounts typically receive $5 in free credits.
Generate an API key from the dashboard.

export ANTHROPIC_API_KEY="sk-ant-your-key-here"

Make API Calls

import anthropic
import os

client = anthropic.Anthropic(api_key=os.environ["ANTHROPIC_API_KEY"])

# Use Claude Sonnet 4 (most cost-effective)
response = client.messages.create(
    model="claude-sonnet-4-20250514",
    max_tokens=1024,
    messages=[
        {"role": "user", "content": "Write a Python class that implements a thread-safe LRU cache with TTL expiration."}
    ]
)

print(response.content[0].text)
print(f"Input tokens: {response.usage.input_tokens}")
print(f"Output tokens: {response.usage.output_tokens}")

Stretch Your Credits

With $5 in API credits, here is how many messages you can get with each model:

Model	Input Price	Output Price	Approx. Messages with $5
Claude Haiku 4	$0.80/1M tokens	$4/1M tokens	~3,000
Claude Sonnet 4	$3/1M tokens	$15/1M tokens	~500
Claude Opus 4	$15/1M tokens	$75/1M tokens	~80

Use Haiku for simple tasks, Sonnet for most work, and Opus only when you need the best reasoning.

Method 3: Google Cloud Vertex AI

Claude models are available through Google Cloud's Vertex AI platform. New Google Cloud accounts get $300 in free credits:

Go to cloud.google.com and click "Start Free."
Create a Google Cloud account with your existing Google account.
You receive $300 in free credits valid for 90 days.
Enable the Vertex AI API and Anthropic's Claude models in the Model Garden.

import anthropic

client = anthropic.AnthropicVertex(
    region="us-east5",
    project_id="your-gcp-project-id"
)

response = client.messages.create(
    model="claude-sonnet-4@20250514",
    max_tokens=1024,
    messages=[
        {"role": "user", "content": "Explain how garbage collection works in Go vs Java."}
    ]
)

print(response.content[0].text)

The $300 in Google Cloud credits goes a long way. Claude Sonnet 4 through Vertex AI costs similar per-token rates as the direct API, giving you roughly 50,000 Sonnet messages or 8,000 Opus messages.

Method 4: Amazon Bedrock Free Tier

AWS Bedrock also offers Claude models, and new AWS accounts get a free tier:

Create an AWS account at aws.amazon.com.
AWS offers a 12-month free tier with various service credits.
Enable Claude models in Amazon Bedrock.
Some Claude models may have specific free tier allocations through Bedrock.

import boto3

client = boto3.client("bedrock-runtime", region_name="us-east-1")

response = client.invoke_model(
    modelId="anthropic.claude-sonnet-4-20250514-v1:0",
    body='{"messages": [{"role": "user", "content": "Hello!"}], "max_tokens": 256, "anthropic_version": "bedrock-2023-05-31"}'
)

Note: Bedrock free tier availability for Claude models varies. Check the current AWS Bedrock pricing page for what is included.

Method 5: Third-Party Platforms with Free Tiers

Several platforms provide access to Claude models through their own free tiers:

Poe.com

Poe (by Quora) offers daily free credits that can be used with Claude models:

Free users get a limited number of messages per day
Claude Sonnet 4 is typically available
Claude Opus 4 may require a subscription

OpenRouter

OpenRouter aggregates multiple AI models and occasionally offers free credits:

from openai import OpenAI

client = OpenAI(
    api_key=os.environ["OPENROUTER_API_KEY"],
    base_url="https://openrouter.ai/api/v1"
)

response = client.chat.completions.create(
    model="anthropic/claude-sonnet-4",
    messages=[
        {"role": "user", "content": "Compare React Server Components vs Astro Islands."}
    ]
)

Perplexity

Perplexity Pro occasionally uses Claude models under the hood. While you cannot directly choose Claude, your queries may be processed by Claude Sonnet when available.

Method 6: Use Claude Code CLI

Claude Code is Anthropic's open-source CLI tool for AI-assisted coding. It uses the API, so your free credits work:

# Install Claude Code
npm install -g @anthropic-ai/claude-code

# Set your API key
export ANTHROPIC_API_KEY="sk-ant-your-key"

# Start coding
claude "explain what this project does and suggest improvements"

Claude Code is particularly efficient with API credits because it uses smart context management -- only sending relevant file contents rather than your entire codebase.

Method 7: Educational and Research Access

Anthropic provides expanded access for specific use cases:

Academic research. Researchers can apply for API credits through Anthropic's research program. If you are affiliated with a university, check if your institution has a partnership.

Nonprofit organizations. Some nonprofits qualify for discounted or free API access. Contact Anthropic's partnerships team.

Hackathons and events. Anthropic frequently sponsors hackathons with free API credits for participants. Follow @AnthropicAI for announcements.
