Google has expanded the capabilities of its Antigravity development platform with updates to Teamwork, a multi-agent orchestration framework that coordinates teams of Gemini-powered AI agents to tackle research and engineering problems that can span hours or days. Google detailed the latest Teamwork updates in an August 27, 2026 post on the Antigravity blog, describing the framework as designed to allow autonomous teams of AI agents to collaborate, critique, and iterate over extended periods to solve complex, long-horizon challenges.
How the Teamwork Framework Is Structured
Teamwork is not a monolithic agent team. Google describes each distinct configuration as a "pattern", a blueprint defining which agents participate, what roles they serve, and the criteria required for work to move forward. The framework dynamically decides how many agents to spawn based on task requirements rather than a preset number, and agent count and team structure can shift mid-run as the problem develops.
Google says the framework ships specialized patterns selected automatically based on the task, including Iterative Coding for non-decomposable problems, Distributed Coding for tasks that can be parallelized across workers with critic review, Long Proof for open-ended mathematics and theoretical computer science, Self-Verification for depth-first mathematical reasoning, and Document Review for structured analysis of papers and technical documents.
The orchestration is organized into tiers: a Sentinel coordinator that takes over once a user approves the prompt, records the request, routes tasks, posts periodic progress updates, and spawns a Success Auditor before wrapping up; and a Project Orchestrator, a dedicated manager spawned to run the project.
Gemini 3.7 Flash as the Underlying Model
Google says Teamwork builds on Gemini 3.7 Flash, which it describes as its most intelligent workhorse model for coding and agents, designed to provide the speed and cost efficiency needed for everyday developer tasks, while Teamwork provides the orchestration needed for more complex, long-horizon work. Gemini 3.7 Flash is generally available, having been released by Google on August 13, 2026. The release came just three weeks after Gemini 3.6 Flash and delivers improvements across software engineering, knowledge work, and web development workflows, at an introductory price of half the original 3.6 Flash cost per million tokens.
Mathematics and Theoretical Computer Science Results
According to Google's August 27 Antigravity blog post, pairing Gemini 3.7 Flash with Teamwork's multi-agent orchestration produced solutions to seven open problems across top academic venues including FOCS and JMLR, including Knuth's Cycles Conjecture, verified in Lean with proofs exceeding 40 pages, as well as sparse convex optimization, provable LLM quantization, and prefix-matrix factorizations, while achieving 71 percent on TCSBench.
Systems Engineering Results
In systems engineering, Google reports that Teamwork built a cycle-accurate, out-of-order RISC-V CPU simulator from scratch capable of booting the xv6 operating system to shell, with a 0.71 percent cycle alignment error against hardware ground truth.
Open-Source Software Contributions
Google also reports that performance optimizations were contributed and merged directly into upstream open-source libraries, including Eigen and ParlayHash. Specific improvements included SIMD fast-paths in Eigen and a 2x insert throughput gain along with a 25 percent memory reduction in ParlayHash.
Availability
Teamwork is powered by publicly available Gemini models, and Google stated it is rolling out these improvements to the /teamwork-preview command in Antigravity over the coming weeks, targeting users working on frontier innovation tasks. The /teamwork-preview command is available on paid plans across Google Antigravity 2.0 and the Antigravity CLI.
For development teams and researchers, the Teamwork results point toward a practical consideration: multi-agent orchestration frameworks differ from single-agent tools in that they introduce independent verification steps and parallel workstreams, which may reduce the risk of a single agent's confident error propagating unchecked through a long-running task. Teams evaluating Antigravity for research or engineering workflows should account for the fact that Teamwork remains labelled as an early research preview.
Google published the Teamwork research results post on August 27, 2026, through the Antigravity blog, where it sits alongside the August 13 announcement of Gemini 3.7 Flash's availability in the platform.
