## Code Arena

Code Arena is a hands-on playground and leaderboard where you can pit leading AI coding models against each other on real web builds, comparing speed, accuracy, and logic in live side-by-side battles.

**Tarifs et offres:** Free to use; no paid tier is advertised on the product page. Related enterprise/API offerings from Arena may be priced separately.

- **Model battles:** Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
- **Real-time app building:** Watch models construct web apps and websites live, so you can see process and output, not just the final file.
- **Multi-file generation:** Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
- **Community leaderboard:** Track which coding models accumulate the most wins over time to identify consistently strong performers.
- **Free browser access:** Run comparisons directly in the browser without installing anything or paying for credits.

**Forces:** Free, no-signup barrier for quick comparisons; Tests full multi-file projects, not just isolated snippets; Live battles reveal model behaviour, speed, and failure modes; Leaderboard aggregates community signal over time

**Limites:** Battles are subjective and depend on the prompts you write; Not a full IDE replacement for day-to-day development; Leaderboard results can shift quickly as new models ship

## TypeSafe AI - Jev

TypeSafe AI is an AI lab building machine-native intelligence infrastructure, and Jev is its first System One Model — a model designed to make decisions inside software rather than reply to humans. Instead of returning strings, Jev accepts structured questions and returns typed decisions with calibrated confidence scores, so applications can act autonomously when confidence is high and escalate for human review when it is not. TypeSafe reports roughly 193x faster and 444x cheaper performance on System One workloads compared with general-purpose LLMs.

**Tarifs et offres:** Paid, with early access to Jev. TypeSafe quotes Jev at $42 per billion input tokens and describes this as roughly 238x lower input pricing than comparable frontier chat models. Enterprise options and API access are arranged through the company, alongside documentation and an API console.

- **Typed decisions, not strings:** Jev outputs typed decisions that application code can act on directly, rather than prose that must be parsed and interpreted.
- **Calibrated confidence on every call:** Every decision carries an estimate of how confident the model is, so you can set thresholds for autonomous action versus human escalation.
- **Reported 193x faster, 444x cheaper:** TypeSafe reports Jev at roughly 193x faster and 444x cheaper than LLM-based workflows on comparable System One tasks, with a price of $42 per billion input tokens.
- **Built to reduce hallucination:** Because confidence estimates expose uncertainty, Jev is designed to avoid hallucination-style failures in automation, enabling zero-hallucination decision paths where confidence is high.
- **Composable workflows with human-in-the-loop:** Combine Jev's per-call decisions inside your own code to construct larger workflows, with explicit control over when intelligence acts and when it defers to a human.

**Forces:** Purpose-built for machine consumers, not human chat; Calibrated confidence enables principled human-in-the-loop thresholds; Reported order-of-magnitude gains in speed and cost for decision tasks; Typed outputs remove the parsing and validation overhead of JSON-mode LLMs

**Limites:** Early access — general availability and some product details are still being finalised; It is not a chatbot; teams expecting conversational output will need to restructure their workflows; Requires engineering effort to consume typed decisions and set confidence thresholds in your own code; Documentation and public pricing details are still evolving
