Laguna by Poolside
Deploying a frontier model on-premises without handing your codebase to a third-party API is, for most enterprises, either impossible or a two-year infrastructure project — Poolside is built to close that gap.
Summary
Poolside ships foundation models — Laguna XS.2 and M.1 — alongside an agent runtime, multi-agent coordination layer, and developer surfaces (IDE extensions, terminal, workflows) designed to run inside your security boundary on Dell hardware or AWS infrastructure. The 256K context window handles long-horizon code tasks without chunking. Where this architecture earns its keep is in regulated or air-gapped environments where sending prompts to an external API is not an option. The wall appears when you need to self-manage the deployment: Forward Deployed Research Engineers are part of the engagement model, which means the path to production runs through Poolside's team, not your own.
Bottom line: Pick this when your CISO has blocked external API calls and you need agents that plan and execute in a sandboxed environment — look elsewhere when you need a pay-as-you-go API you can wire up this afternoon.
Pros
- On-premises and air-gapped deployment options mean your code and prompts never touch an external API, so teams in regulated industries or defense can use frontier-class models without a data residency exception.
- End-to-end traces on every agent action, so compliance and security teams have an auditable record of what the model decided and executed — without bolting on a third-party logging layer.
- 256K context window handles full repository scans or long-horizon refactoring tasks in a single pass, so you avoid the context-splitting workarounds that break multi-file code reasoning.
- Native multi-agent coordination with sandboxed code execution, which means agents can run tasks in parallel and execute generated code without you wiring together separate runtimes.
- Provider-agnostic infrastructure support across multi-cloud and legacy environments means you do not need to standardize your stack before deploying, which removes the usual prerequisite rip-and-replace project.
Cons
- The engagement model requires Forward Deployed Research Engineers embedded with your team — there is no self-serve path described. For teams that need to deploy and iterate on their own schedule, this adds coordination overhead and a vendor dependency that does not disappear after go-live.
- No open weights and no public API are mentioned anywhere in the vendor materials. Teams that hit a capability ceiling or need to fine-tune the model on proprietary data will have limited options outside the Poolside engagement model — the condition under which teams switch to Claude 3.5 Sonnet or GPT-4o is precisely when they need faster iteration cycles or fine-tuning control that a proprietary, vendor-managed deployment cannot provide.
- Pricing is enterprise-negotiated with no self-serve tier described. Teams running a proof-of-concept with a limited budget have no documented path to get hands on the model without initiating an enterprise sales process.

Poolside provides proprietary foundation models purpose-built for software engineering workflows, delivered with an agent runtime that lets those models plan, call tools, and execute code inside sandboxed environments. The core workflow runs on-premises or in a customer VPC: models are deployed inside your boundary, connected to your repositories, databases, and private corpora through purpose-built connectors, and governed by role-based access control applied to both human users and agents. Traces are captured end-to-end, which means audit trails exist for every agent decision — a requirement in enterprise environments where compliance teams review AI actions after the fact.
The differentiating feature is the deployment model itself. Most frontier model providers offer API access; Poolside’s stated architecture deploys the model weights and agent runtime inside your infrastructure, on-prem via Dell or in your own AWS environment. The vendor describes Forward Deployed Research Engineers who embed with customer teams and take joint responsibility for outcomes — not a handoff, but a co-ownership arrangement. For defense and regulated industries, air-gapped deployment on workstations is also described as an option.
This fits teams building agentic software engineering workflows — autonomous PR generation, code review, multi-step refactoring — inside environments where data cannot leave the building. It breaks, or at least slows down, when your team wants to iterate fast without an embedded vendor team involved: the engagement model is designed for high-consequence, high-coordination deployments, not rapid prototyping. Teams that need a simple REST endpoint and a credit card will find the procurement and deployment process mismatched to their timeline.
Technical specifics from the vendor: the Laguna XS.2 and M.1 models ship with a 256K token context window. Developer surfaces include IDE extensions, a terminal UI (TUI), binaries, and workflow tooling. Multi-agent orchestration is described as supported natively, with policies and traces governing agent behavior across heterogeneous environments including multi-cloud and legacy systems — no infrastructure replacement required, according to the vendor.
