Best Free AI for Coding
Selection framework
This guide explains the different forms of free access—trials, free tiers, no-login entry points, and open APIs—and leaves changing regional limits, quotas, and terms to the official pages.
What to evaluate
- Distinguish a trial, a free tier, a no-login entry point, and an open API—they are not equivalent.
- Confirm the region, sign-in, and usage conditions shown on the official site before real work.
- Do not treat a free entry point as a production SLA; keep human review for important work.
Validate the same task with ModelAny
Send one prompt for a real task that matches your use case to DeepSeek, Gemini, ChatGPT (and any other services you select), then compare factual accuracy, actionability, and how much editing each result needs. ModelAny only opens and fills the selected services; each provider remains responsible for its answers, plans, and data terms.
- Write down success criteria such as verifiability, editing time, and privacy requirements.
- Compare available models with the same input so prompt differences do not distort the result.
- Record the output, human edits, and failures before choosing a long-term workflow.
What public benchmarks show
Below are results only from public benchmark categories where every model on this page appears together. Scores from different sources cannot be added up, and they do not prove one model is best overall.
Arena · coding preference
Arena asks people to pick the better answer without knowing which model wrote it. A higher Elo means more preference votes in that category—not an overall product ranking.
| Product | Exact model version | Rank | Score | Metric |
|---|---|---|---|---|
| ChatGPT | gpt-5.6-sol-xhigh (codex-harness) | 3 | 1625 | Elo (Elo) |
| Gemini | gemini-3.6-flash | 15 | 1526 | Elo (Elo) |
| DeepSeek | deepseek-v4-pro-thinking | 31 | 1464 | Elo (Elo) |
SWE-bench Verified · real software-issue fixing
SWE-bench Verified measures how often an AI coding setup can fix real GitHub issues. A higher resolved percentage means more issues were fixed in that specific test setup.
| Product | Exact model version | Rank | Score | Metric |
|---|---|---|---|---|
| Gemini | live-SWE-agent + Gemini 3 Pro Preview (2025-11-18) | 4 | 77.4% | Resolved (%) |
| ChatGPT | JoyCode + Claude 4 Sonnet + GPT-4.1 | 17 | 74.6% | Resolved (%) |
| DeepSeek | mini-SWE-agent + DeepSeek V3.2 (high reasoning) | 46 | 70% | Resolved (%) |

Frequently asked questions
Does this page publish an absolute ranking?
No. We compare models only where they share the same public test conditions, and we link to the original sources so you can verify. We don't publish a “best overall” list outside a stated context.
Are pricing and plan details definitive?
This page links to official sources and verification dates. Confirm the price and terms shown for your region on the provider site before purchasing or deploying.
Does ModelAny store prompts?
ModelAny is local-first: drafts, settings, and history stay in your browser. Prompts are sent only to the AI services you choose and are not uploaded to ModelAny servers.
