Top 5 free models for long-form roleplay on JanitorAI (2026)

Finding a model that balances rich, descriptive prose, tight character consistency, and a genuinely free tier is hard. Commercial APIs get expensive fast once you're running long context windows, so a lot of the roleplay community has moved to open-weight models served through free proxy services like MegaNova AI, which plugs into Janitor AI's custom API settings.

If you want deep, novel-length prose without draining your wallet, these are the top 5 free models you should be running on Janitor AI right now via MegaNova's Tier-1 access.

1. Manta-Flash-1.0 — best for fast, in-character banter

  • Developer/host: MegaNova AI (proxy-hosted, not independently benchmarked elsewhere)
  • Free-tier access: Yes — this is MegaNova's flagship free roleplay model
  • Why it's picked: MegaNova positions the Manta line specifically for uncensored, creative roleplay. Manta-Flash-1.0 balances response speed and quality, making it one of the more solid free options for powering Janitor AI chats. The family also includes Manta-Mini-1.0 (faster and lighter) and Manta-Pro-1.0 (larger and more nuanced), so you can trade speed for depth depending on the scene.

2. Sapphira-L3.3-70B-0.1 — best for descriptive, world-building-heavy prose

  • Developer/host: Community fine-tune on Llama 3.3, hosted free via MegaNova
  • Free-tier access: Yes, via MegaNova's proxy
  • Why it's picked: This is a 70-billion-parameter roleplay-tuned model — not 12 billion, as sometimes miscited — built specifically to minimize the friction that breaks immersion, prioritizing creative flow so character development and emotional arcs stay coherent over long sessions. At 70 billion parameters, it is a genuinely large model to be getting for free. MegaNova claims sub-second streaming on its inference cloud, though that is a provider claim, not an independent benchmark.

3. DeepSeek-V4-Flash— best for long, punchy back-and-forth threads

  • Developer: DeepSeek (official lab release, not a roleplay fine-tune)
  • Price: $0.10/M in - $0.20/M out
  • Specs: DeepSeek V4 Flash was released on April 24, 2026, under the MIT license. It is a 284-billion-total-parameter, 13-billion-active-parameter Mixture-of-Experts model with a 1-million-token context window — genuinely huge, not "lightweight" in absolute terms, just lighter than its 1.6-trillion-parameter sibling, V4 Pro.
  • Why it's picked: The large context window and MoE efficiency mean it holds up well across long roleplay threads without the usual quality drop-off, though independent reviewers note that it can read as strong on standard benchmarks but less consistent in day-to-day practical use.

4. Gemma 4 (31B) — best for logic tracking and self-hosting

  • Developer: Google DeepMind
  • Specs: Gemma 4 was released on April 2, 2026, in four sizes — E2B, E4B, 26B, and 31B — under the Apache 2.0 license, a real licensing shift from earlier Gemma generations. The 31B dense variant supports a 128K–256K token context window.
  • Why it's picked: If you have the hardware (or use a service that hosts it, like Ollama locally), the 31B holds long-term relationship and plot tracking well, per its strong reasoning benchmark scores. It's the "no subscription, no proxy dependency" option on this list.

5. Kimi K3 — best for massive session recall

  • Developer: Moonshot AI
  • Free-tier access: Available via Kimi.com's own chat interface and as downloadable weights; not confirmed as part of MegaNova's Janitor AI proxy line-up, so don't assume it'll show up in that specific dashboard.
  • Spec: Kimi K3 is a 2.8-trillion-parameter, open-weight Mixture-of-Experts model with native vision support and a 1-million-token context window. Released by Moonshot AI in mid-2026, it is roughly 75% larger than DeepSeek V4 Pro and is described by Moonshot as the largest open-weight 3T-class model released to date.
  • Why it's picked: Kimi's whole public identity is built around long-context recall, which matters if you want a bot to remember plot details from a session you started months ago rather than just the last few dozen messages.

Pro tip for free-tier users

Keep your prompt settings clean and free of conflicting instructions — vague or contradictory system prompts are still the most common cause of models hallucinating or producing empty responses, regardless of which model you're running. And because free tiers on third-party proxies change terms and availability frequently, re-check the provider's dashboard before assuming a model or quota mentioned in any guide (including this one) is still current.
