It maps your repo, edits files, and commits every change to git. It also burns through tokens. Every request carries a repo map, the files you added to the chat, and the conversation so far. Pair that with Claude Opus or Sonnet at official Anthropic rates and a busy week of refactoring can turn into a three-figure bill.<\/p>\n<p>The good news: Aider talks to any OpenAI-compatible endpoint. That means you can keep the exact same Claude models and point Aider at a cheaper gateway. This guide shows how to run <strong>Aider with a cheap Claude API<\/strong> through Qora API, what it actually costs per model, and how to cut your token use even further.<\/p>\n<h2>Why Aider gets expensive with Claude<\/h2>\n<p>Aider&#8217;s token use comes from three places:<\/p>\n<ul>\n<li><strong>The repo map.<\/strong> Aider sends a compressed map of your codebase so the model knows where things live. On a large repo this alone is thousands of tokens per request.<\/li>\n<li><strong>Files in the chat.<\/strong> Every file you <code>\/add<\/code> is sent in full on every turn until you <code>\/drop<\/code> it.<\/li>\n<li><strong>Chat history.<\/strong> Long sessions keep re-sending earlier messages, so input tokens grow with every turn.<\/li>\n<\/ul>\n<p>Input tokens usually outnumber output tokens many times over in a coding session. So the per-token input price matters most, and that is exactly where a discount pays off.<\/p>\n<h2>Claude API cost for Aider: official vs Qora<\/h2>\n<p>These are per-million-token prices. Official prices come from Anthropic&#8217;s pricing page; Qora prices come from the <a href=\"https:\/\/qoraapi.com\/pricing\">Qora pricing page<\/a>. Every model below is cheaper on Qora than buying direct.<\/p>\n<table>\n<thead>\n<tr>\n<th>Model (Qora model ID)<\/th>\n<th>Official input \/ output<\/th>\n<th>Qora input \/ output<\/th>\n<th>You save<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><a href=\"https:\/\/qoraapi.com\/models\/claude-opus-4-7-api\">Claude Opus 4.7<\/a> (<code>claude-opus-4-7<\/code>)<\/td>\n<td>$5 \/ $25<\/td>\n<td>$1.50 \/ $7.50<\/td>\n<td>70%<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/qoraapi.com\/models\/claude-sonnet-4-6-api\">Claude Sonnet 4.6<\/a> (<code>claude-sonnet-4-6<\/code>)<\/td>\n<td>$3 \/ $15<\/td>\n<td>$0.90 \/ $4.50<\/td>\n<td>70%<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/qoraapi.com\/models\/claude-sonnet-5-api\">Claude Sonnet 5<\/a> (<code>claude-sonnet-5<\/code>)<\/td>\n<td>$2 \/ $10<\/td>\n<td>$0.60 \/ $3.00<\/td>\n<td>70%<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/qoraapi.com\/models\/claude-haiku-4-5-api\">Claude Haiku 4.5<\/a> (<code>claude-haiku-4-5-20251001<\/code>)<\/td>\n<td>$1 \/ $5<\/td>\n<td>$0.30 \/ $1.50<\/td>\n<td>70%<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/qoraapi.com\/models\/claude-opus-5-5-api\">Claude Opus 5.5<\/a> (<code>claude-opus-5-5<\/code>)<\/td>\n<td>$4 \/ $20<\/td>\n<td>$2.40 \/ $12.00<\/td>\n<td>40%<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/qoraapi.com\/models\/claude-sonnet-5-5-api\">Claude Sonnet 5.5<\/a> (<code>claude-sonnet-5-5<\/code>)<\/td>\n<td>$2 \/ $10<\/td>\n<td>$1.20 \/ $6.00<\/td>\n<td>40%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The newest Claude 5.5 models run on Qora&#8217;s Stable group at about 60% of the official price.

Setup takes about two minutes.<\/p>\n<h3>Step 1: Create an account and an API key<\/h3>\n<ol>\n<li>Sign up at <a href=\"https:\/\/qoraapi.com\/register\">qoraapi.com\/register<\/a>.<\/li>\n<li>Create an API key in your dashboard.<\/li>\n<li>New user? Message <a href=\"https:\/\/x.com\/QoraAPI\">@QoraAPI on X<\/a> or email support@qoraapi.com to get <strong>$5 of free trial credit<\/strong>, enough to test Aider on a real repo.<\/li>\n<\/ol>\n<h3>Step 2: Install Aider<\/h3>\n<pre><code>python -m pip install aider-install\naider-install<\/code><\/pre>\n<h3>Step 3: Point Aider at Qora<\/h3>\n<p>Set your endpoint and key as environment variables:<\/p>\n<pre><code># Mac \/ Linux\nexport OPENAI_API_BASE=https:\/\/qoraapi.com\/v1\nexport OPENAI_API_KEY=your-qora-key\n\n# Windows (restart the terminal afterwards)\nsetx OPENAI_API_BASE https:\/\/qoraapi.com\/v1\nsetx OPENAI_API_KEY your-qora-key<\/code><\/pre>\n<h3>Step 4: Start Aider with a Claude model<\/h3>\n<p>Prefix the Qora model ID with <code>openai\/<\/code> so Aider routes it through the OpenAI-compatible endpoint:<\/p>\n<pre><code>cd \/path\/to\/your\/project\naider --model openai\/claude-sonnet-4-6<\/code><\/pre>\n<p>Aider may print a warning that it does not recognize the model&#8217;s context window or pricing. That is expected for custom endpoints and does not affect the requests. Add <code>--no-show-model-warnings<\/code> to hide it.<\/p>\n<h3>Step 5: Save it in a config file<\/h3>\n<p>To avoid typing flags every time, create <code>.aider.conf.yml<\/code> in your project or home directory:<\/p>\n<pre><code>openai-api-base: https:\/\/qoraapi.com\/v1\nopenai-api-key: your-qora-key\nmodel: openai\/claude-sonnet-4-6\nweak-model: openai\/claude-haiku-4-5-20251001\nshow-model-warnings: false<\/code><\/pre>\n<p>Do not commit this file if it holds your key. Add it to <code>.gitignore<\/code>, or keep the key in an environment variable instead.<\/p>\n<h2>Cost-cutting tips for Aider<\/h2>\n<h3>1. Use a cheap weak model<\/h3>\n<p>Aider uses a &#8220;weak model&#8221; for side jobs like writing commit messages and summarizing chat history. Setting it to <code>openai\/claude-haiku-4-5-20251001<\/code> ($0.30 \/ $1.50 on Qora) keeps those calls nearly free.<\/p>\n<h3>2. Use architect mode with two models<\/h3>\n<p>Architect mode lets one model plan and another apply the edits. Plan with a strong model and edit with a cheaper one:<\/p>\n<pre><code>aider --architect \\\n  --model openai\/claude-opus-4-7 \\\n  --editor-model openai\/claude-sonnet-4-6<\/code><\/pre>\n<p>Opus handles the hard reasoning; Sonnet writes the diffs at $0.90 \/ $4.50 instead of Opus rates.<\/p>\n<h3>3. Keep the chat lean<\/h3>\n<ul>\n<li><code>\/add<\/code> only the files the change needs, and <code>\/drop<\/code> them when you are done.<\/li>\n<li>Run <code>\/clear<\/code> between unrelated tasks so old history stops riding along.<\/li>\n<li>Use <code>\/tokens<\/code> to see what is eating your context before it eats your budget.<\/li>\n<\/ul>\n<h3>4. Match the model to the task<\/h3>\n<p>Most day-to-day edits, tests and small refactors run well on Sonnet 4.6 or Sonnet 5. Save Opus for gnarly multi-file changes.

Top up as a partner if you spend a lot<\/h3>\n<p>Qora is pay-as-you-go with no subscription. Partners get an extra 30% on every top-up: put in $1,000 and get $1,300 of credit.<\/p>\n<h2>Using other coding tools too?<\/h2>\n<p>The same key works across your tools.

Aider supports any OpenAI-compatible endpoint. Set <code>OPENAI_API_BASE<\/code> to <code>https:\/\/qoraapi.com\/v1<\/code> and use model names like <code>openai\/claude-sonnet-4-6<\/code>.<\/p>\n<h3>What is the cheapest Claude model for Aider?<\/h3>\n<p>Of the models in the table above, Claude Haiku 4.5 is the cheapest at $0.30 \/ $1.50 per million tokens on Qora. For serious coding, Claude Sonnet 5 at $0.60 \/ $3.00 is the best value among the stronger models.<\/p>\n<h3>Is it the same Claude model?<\/h3>\n<p>You call the same model IDs, such as <code>claude-opus-4-7<\/code> and <code>claude-sonnet-4-6<\/code>. Qora is a gateway, so you get one key for Claude, GPT, Gemini and 350+ other models.<\/p>\n<h3>Can I use Qora with tools that need the Anthropic API format?<\/h3>\n<p>Yes. Claude models also have an Anthropic-compatible endpoint with base URL <code>https:\/\/qoraapi.com<\/code>. Aider itself only needs the OpenAI-compatible one.<\/p>\n<h3>Do I need a subscription?<\/h3>\n<p>No. Qora is pay-as-you-go. You only pay for the tokens you use. See full rates on the <a href=\"https:\/\/qoraapi.com\/pricing\">pricing page<\/a> or browse every model at <a href=\"https:\/\/qoraapi.com\/models\">qoraapi.com\/models<\/a>.<\/p>\n<h2>Start using Aider for less<\/h2>\n<p>Aider is worth every token. You just do not need to pay full price for them. <a href=\"https:\/\/qoraapi.com\/register\">Create your Qora account<\/a>, set two environment variables, and keep coding with Claude at up to 70% off official rates.
