PLaMo 3.0 Prime Deep Dive — Preferred Networks' Flagship Japanese LLM Officially Released June 22, 2026, Expanded from 64K to 256K Context, Dual Reasoning / Non-reasoning Variants, ¥60 / ¥250 per 1M Tokens, Selected for the Digital Agency's Common 'Gennai' Generative-AI Platform, Built From-Scratch on NICT Collaboration and METI GENIAC Phase 3 Outputs
**Preferred Networks (PFN) officially released PLaMo 3.0 Prime on June 22, 2026** ([official press pr20260622](https://www.preferred.jp/ja/news/pr20260622) / [tech blog](https://tech.preferred.jp/ja/blog/plamo-3-0-prime-release/)). Successor to PLaMo 2.0 Prime (2025 Nikkei Excellent Product Award grand prize), this is the production rollout after a 3-month monitor program following the March 19, 2026 beta. **Context extended from 64K beta → 256K production**, **dual Reasoning / Non-reasoning variants**, proprietary tokenizer optimized for Japanese token efficiency, post-training with SFT + DPO + RL. **Compared against** gpt-oss-120b / Qwen3.6-27B (open) and GPT-5.4 mini / Claude Haiku 4.5 (closed in the same price tier). **Evaluated on 15 benchmarks**: JFBench / IFBench / Japanese MT-Bench / lawqa_jp / MedRECT / Japanese Medical Licensing Exam / MT-Bench / AIME 2024 / GPQA-Diamond / BFCL / LongBench v2 / HELM Safety. PFN CEO/CTO Daisuke Okanohara claims parity or superiority over same-tier models on Japanese instruction-following, coding, and tool-use, while ITmedia at the beta stage noted weakness in math and multi-tool selection. **Pricing is aggressive**: Standard plan **¥60 input / ¥250 output per 1M tokens** (up to 128K), Free plan pending, Provider plan custom-quoted. **Distribution**: PLaMo API (SaaS), on-premise, Amazon Bedrock Marketplace, Snowflake. **Prime itself is closed-weights**, but NICT-co-developed base models `plamo-3-nict-2b/8b/31b-base` are open on Hugging Face. **Adoption**: standard model in miibo / Tachyon / QommonsAI, and **selected as a trial model for the Japanese Digital Agency's common generative-AI platform 'Gennai'**. **Not disclosed**: parameter count, dense vs MoE, and independent third-party benchmark verification — pending Nejumi LLM Leaderboard registration.
