MiniMax M2.7 is a 230B-parameter Mixture-of-Experts reasoning model released as open weights in April 2026. Only 10 billion parameters activate per token (8 of 256 experts), which enables frontier-level performance at significantly lower inference cost and latency than dense models of comparable quality. The context window stretches to 204,800 tokens — roughly 307 pages of text — with strong performance on long-horizon agentic tasks. M2.7 is purpose-built for tool-using agents and coding workflows. It scored 50 on the Artificial Analysis Intelligence Index, placing it among the top open-weight models globally. Weights landed on Hugging Face simultaneously with an API launch and the open-sourcing of OpenRoom, MiniMax's interactive agent orchestration system — a rare move that gives developers the full stack from model to agent runtime. MiniMax is a Shanghai-based AI company that has been quietly iterating through M1, M2, M2.5, and now M2.7 with consistent improvements. The M2.7 release represents a notable capability jump in the MoE open-weights space, particularly for developers who need a locally deployable model that can handle complex multi-step agent tasks without calling a paid API.

Tencent open-sourced Hy3 Preview on April 23, 2026 — the first model to emerge from the company's rebuilt AI infrastructure, and its most credible challenge to frontier closed models to date. With 295 billion total parameters but only 21 billion active at inference time (plus 3.8B MTP layer parameters), it's a Mixture-of-Experts architecture that punches far above its compute weight. The model supports up to 256K context and is available via Hugging Face, ModelScope, and GitCode under the Tencent Hy Community License. On coding benchmarks, Hy3 scores 74.4% on SWE-bench Verified, 54.4% on Terminal-Bench 2.0, and 67.1% on BrowseComp — placing it firmly in the same tier as top models from Anthropic and OpenAI. Tencent claims a 40% efficiency improvement over its predecessor Hunyuan models, and pricing through Tencent Cloud TokenHub is aggressive: RMB 1.2 per million input tokens. A free two-week window at launch via OpenRouter made it widely accessible immediately. The model was led by a team that includes former OpenAI researchers and has already been deployed across Tencent's core products — WeChat, Yuanbao, and QQ. That production integration is a meaningful signal: this isn't a benchmark vanity release. For developers who need a powerful, cost-efficient reasoning and agentic model with actual open weights, Hy3 Preview is one of the most interesting drops of April 2026.
Reviewer scorecard
“Only 10B active params with 230B total is a sweet spot — you get near-frontier quality with manageable inference costs. The open-sourced OpenRoom agent runtime alongside the weights makes this a production-ready stack, not just a model drop.”
“21B active params with 295B total — this is genuinely practical to deploy on reasonable hardware while matching models 10x the inference cost. The 256K context and strong SWE-bench score make it a legitimate option for agentic coding pipelines. I'd use this today.”
“MiniMax is still less battle-tested than Qwen or Llama in community tooling. 230B total weights still require serious hardware even with MoE efficiency. And the version cadence (M2 to M2.5 to M2.7) suggests rapid deprecation cycles.”
“The Tencent Hy Community License is not Apache 2.0 or MIT — read it carefully before using this in production. There are usage restrictions that could bite commercial deployments. Also, benchmark scores look great, but independent evals of Chinese labs' models have historically diverged from self-reported numbers.”
“The combination of open-source agent runtime plus frontier-adjacent open weights is exactly the stack needed to enable truly sovereign AI deployments. MiniMax is quietly building one of the most complete open-source AI stacks in the world.”
“The MoE efficiency race is the actual story here — we're getting frontier-class capability at a fraction of the activation cost. Hy3 is proof that the compute-vs-capability Pareto frontier keeps moving. Open weights with real deployment signals (WeChat at scale) is a combination that matters.”
“For pure creative tasks, the MoE trade-offs in consistency aren't ideal. Locally running a 230B model is still not practical for most creator workflows without dedicated GPU infrastructure.”
“Strong visual coding capabilities and multimodal understanding make this genuinely useful for design-to-code workflows. The health image analysis and product comparison use cases already deployed in Yuanbao show real-world creative utility beyond pure benchmark games.”
