Claude Opus 4.7 is Anthropic's latest flagship model, released April 16. It scores 87.6% on SWE-bench Verified — a 13-point improvement over Claude Opus 4.6 — and 94.2% on GPQA, making it competitive with the top frontier models on coding and scientific reasoning benchmarks. The context window extends to 1 million tokens with substantially improved retrieval accuracy at the far end of the window. The release introduces "Routines" — a first-party feature for defining persistent agentic workflows that Claude can execute autonomously across multiple sessions. Routines are defined in structured YAML and can include tool calls, conditional logic, and human-in-the-loop checkpoints. Anthropic positions this as a more reliable alternative to custom agent frameworks for common use cases. Pricing remains unchanged from Opus 4.6: $5/M input tokens, $25/M output tokens. The vision input resolution has been increased by 3.3x, which meaningfully improves performance on documents, diagrams, and UI screenshots. Available via API immediately and rolling out to Claude.ai Pro and Team plans over the next week.

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
“87.6% on SWE-bench isn't a small improvement — that's a meaningful jump for real-world coding tasks. The Routines feature addresses the biggest pain point with Claude in production: reliable multi-step agent behavior without building a custom framework.”
“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.”
“Benchmarks look great but the 1M context window performance hasn't been independently validated at the limits. Routines sound powerful but the YAML spec is still in beta with known edge cases. If you're running stable Opus 4.6 workflows, wait a week for the community to stress-test this before migrating.”
“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.”
“Anthropic is quietly winning the enterprise coding agent race. The combination of top SWE-bench scores with the Routines feature is a moat — developers don't switch orchestration frameworks easily once workflows are deployed. This release deepens that lock-in strategically.”
“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.”
“The 3.3x vision resolution upgrade is underrated for design work. Document analysis, layout review, and iterating on visual mockups are all dramatically better. I can finally paste a full Figma export and get coherent feedback on the entire design rather than just the top half.”
“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.”
