V3Code runs one agent across several models. You pick the model, or let the router pick — the mode and everything else stays the same. The whole system is built around one idea: get the best models while keeping caching intact so it stays cheap.
The V3 models (DeepSeek, optimized)
Section titled “The V3 models (DeepSeek, optimized)”- v3fast — an optimized version of DeepSeek V4 Flash: quick and cheap for everyday edits.
- v3pro — an optimized version of DeepSeek V4 Pro: the stronger workhorse the editor was built around.
“Optimized” means the system around them is tuned to cache well and do the most with the fewest tokens — that’s where a lot of the cost savings come from.
The Anthropic hybrids
Section titled “The Anthropic hybrids”These ship as hybrids that consult Anthropic — a cheaper model does the work and calls in a stronger one only when the task gets hard, so you get top-tier results without paying top-tier prices on every step.
| Hybrid | How it works |
|---|---|
| Opus Easy | Haiku does the work and calls Opus for the difficult parts. |
| Opus Hard | Sonnet 5 does the work and calls Opus when needed. |
| Hybrid (switching) | Switches between Sonnet, Opus, and Fable 5 as the task demands. |
To you it behaves like a single model — the switching and escalation happen underneath.
Auto: let it route
Section titled “Auto: let it route”Auto picks and escalates for you. A cheaper model handles the easy steps and a stronger one takes over when needed. Auto is tuned to preserve prompt caching rather than break it — reshuffling the context every turn would throw away the cache and run up the bill, so V3Code steers the agents to keep the cache working.
Free, BYOK, and paid
Section titled “Free, BYOK, and paid”- Connected plans let you sign in to supported provider subscriptions and bring the models they expose into the V3Code picker without pasting an API key. Usage counts against that provider’s plan. See Use your existing provider plans.
- Free agent models are available through a best-effort rotating lane. The roster and capacity change, so it may be less reliable than a connected plan, BYOK, hosted, or local model.
- We work hard on the caching to make Anthropic as good as possible for BYOK users (your own Anthropic key) and as cheap as possible for paid users.
- Paid users get customized versions of the Auto and hybrid routers — tuned to save money and use the fewest tokens. These are unlocked for paid BYOK users and paid plan users.
See Connected plans for subscriptions, BYOK for keys, and V3Code plans for what’s unlocked where.
