Claude Opus 4.7, released April 16, 2026, is Anthropic's strongest model to date and introduces a meaningful new primitive for agentic work: task budgets. A task budget gives Claude a token target for the entire agentic loop — thinking, tool calls, tool results, and final output — with a running countdown that lets the model prioritize and wind down gracefully rather than running out of context mid-task. Beyond task budgets, Opus 4.7 ships with substantially better vision at higher resolutions, improved creative output quality (better interfaces, slides, and docs), and gains on the hardest software engineering tasks where Opus 4.6 struggled to maintain context across long refactors. Pricing stays flat at $5/1M input and $25/1M output. Available day-one across Claude Pro, API, Amazon Bedrock, Vertex AI, Microsoft Foundry, Claude Code, Cursor, and GitHub Copilot, Opus 4.7 cements Anthropic's position as the go-to model for serious agentic workloads — particularly long-horizon coding sessions that previously needed close human supervision.

Gemini 3.1 Ultra is Google's most capable model to date, featuring a stable 2 million token context window — enough to process 1,500+ pages of text, hours of video, or an entire large codebase in a single session. Unlike prior Gemini versions that stitched modalities together, 3.1 Ultra was trained from the ground up to reason across text, image, audio, and video simultaneously without transcription intermediaries. It also ships with native sandboxed Python execution: write code, run it, observe the output, revise — all within a single API call. On benchmarks, Gemini 3.1 Ultra shows meaningful gains on ARC-AGI-3, GPQA Diamond, and SWE-Bench Pro, while its long-horizon planning and agentic capabilities are improved over 3.0. The 2M context window is particularly significant for enterprise use cases involving large document sets, video analysis, and extended software projects. Multimodal inputs include chart reading, diagram interpretation, and frame-by-frame video analysis. Available through the Gemini API and Google AI Ultra subscription, Gemini 3.1 Ultra positions Google squarely against OpenAI's GPT-5.5 and Anthropic's Claude Opus 4.7 at the frontier. The sandboxed code execution removes the need for third-party Code Interpreter plugins, and the model's native multimodal design means developers can pass raw audio or video without preprocessing.
Reviewer scorecard
“Task budgets are the most useful new feature in a model release this year. I can now hand off a 4-hour refactor with confidence that Claude won't run off the rails or stall out at 80%. The hard coding gains are real — agentic loops on big codebases feel qualitatively different.”
“The native sandboxed Python execution is a major unlock. Being able to write, run, and iterate on code within the same API call — without stitching together a Code Interpreter plugin — simplifies a lot of agentic workflows. The 2M context window makes whole-repo analysis actually practical rather than theoretically possible.”
“At $25/1M output tokens, a single complex agentic loop can easily cost $5-10. Task budgets help, but they're a bandaid on the fundamental cost problem. For most teams, Sonnet 4.6 delivers 80% of the capability at 20% of the price.”
“We've seen frontier model releases every few months and the benchmark improvements are getting smaller. 'Trained natively multimodal' was also claimed for Gemini 1.5 and 2.0. The 2M context window is impressive but most applications don't need it, and the cost at that scale is non-trivial. GPT-5.5 and Claude Opus 4.7 are both serious competition.”
“Task budgets represent a real shift in how we think about agent control — not 'stop the agent if it goes wrong' but 'give the agent enough rope to finish, not enough to hang itself.' This mental model will propagate across the industry.”
“A 2M context window that natively understands video is a qualitative leap for enterprise AI. Imagine analyzing an entire quarter of earnings calls, legal discovery sets, or a full feature film for post-production — all in one shot. The sandboxed execution loop is the building block for fully autonomous data science agents.”
“The higher-resolution vision and tasteful output quality improvements are immediately noticeable in design-adjacent tasks. Generating polished slides and landing pages feels less like prompting a robot and more like briefing a designer.”
“Native audio and video understanding without transcription intermediaries is huge for content workflows. Passing raw video directly and getting intelligent analysis — not just captions — opens up automated editing assistants, content QA, and creative research tools that weren't practical before. Google finally has a model worth building creative tools on.”
