Why now

The thing that changed.

For decades, the slow part of software & sre was the iteration loop — specifying the case, queuing the solve, parsing the result, deciding what to try next. Aether collapses that loop into an autonomous agent flow. The iteration count per quarter is what compounds, not any one solve being faster.

One model, not five

The same foundation model serves docking, structural FEA, RTL signoff and wet-lab campaigns. Specialisation lives in the agents and the workloads — not in different models with different training data and different blind spots.

Autonomy, not assistance

Aether doesn't ask you to drive its solvers. It plans the study, picks the method, runs the agents, validates against measured reality, and writes the memo. The work that took a senior engineer a quarter takes the model an afternoon.

Reality is the regulariser

We train on simulation trajectories, instrument data and design history — the substrate of the physical world. The model gets better the more reality it touches, and reality is what tells it when it's wrong.

Industry

The state of software & sre today.

We work where the work is hard, the data is closed and the renewals are seven-figure. Software & SRE is one of those places. Here's how the discipline looks today, what the leaders are doing, and where Aether fits.

Where the work is today

Teams in software & sre run on a stack assembled over thirty years — a CAD core, a meshing tool, a solver, a post-processor, a scheduling layer and a results manager. Each is a separate seven-figure renewal. The hand-offs between them are where time is lost — case setup, queue, re-mesh, comparison, memo.

What the leaders are doing

The leading teams are investing in internal platforms — wrappers around the incumbent tools, glue code, scheduling layers, a Python notebook on top. It works. But it ages badly, ties up senior engineers and doesn't compound. The best teams know they need the next layer; most don't know what it looks like.

Where Aether fits

Aether replaces the spine of that stack with a foundation model trained on simulation, instrument data and design history. The glue layer goes away. Workflows that used to live in a queue and a folder of scripts live in an autonomous agent flow. You keep the niches that work; Aether retires the middle.

What it replaces

The stack today.

The list below is the typical stack in this discipline. Aether replaces the spine. Niches stay where they are; we're not in the business of forcing rip-and-replace on the things that work.

Workloads

What we cover in software & sre.

Each workload below ships with validated benchmarks, agent traces you can read, and a pilot pattern we've run before. Many per discipline — not a wish-list.

Whole-repo edits

Planned changes scoped to a blast radius, executed across files, verified against your tests. Reviewer sees a plan, then a diff.

Cross-language migration

Python → Go, Java → Kotlin, JS → TS, Ruby → Python, C → Rust — semantics-preserving migrations with diffable steps.

Performance in-loop

Reads py-spy, perf, eBPF, Pyroscope flamegraphs. Proposes the change. Verifies the regression suite. Numbers go in the PR.

CVE-aware review

OWASP + CVE-indexed review on every diff. Findings ship with the proposed fix and the test that would have caught it.

On-call drafts

Reads logs, opens incidents, runs runbooks, drains traffic, writes the postmortem first draft — under your approval gates.

Migration playbooks

Service-mesh adoption, monorepo splits, framework upgrades — staged, observable, reversible.

Everything the platform does

The full capability map.

The depth behind the six workloads above. Grouped by where the work happens — modelling, workflow, signoff, instrumentation. Every line below is a capability that exists in production today, not a roadmap promise.

Edits & review
  • Whole-repo edits

    Planned edits across many files with reversible patch sets. Cross-file invariants are inputs, not afterthoughts.

  • Repo-aware planning

    Step-by-step plans with named files, posted before any code is written. No black-box churn.

  • Code review

    Policy-aware review that mirrors your team's PR rules — style, ownership, accessibility, perf budget.

  • Cross-language migration

    Semantic-equivalence proofs across six target languages. Move legacy systems without rewriting them by hand.

Quality & security
  • Test generation

    Unit, integration, property-based and adversarial tests generated against the change.

  • CVE-aware review

    Vulnerability scanning at PR time, with the patch suggested in-line.

  • Performance profiling

    Hotspot detection, regression catching, baseline-aware perf budgets.

  • Taint analysis

    Source-to-sink data-flow review for injection and confused-deputy classes.

Ecosystem
  • Every IDE surface

    The same agent across editors, hosted agents and CI. Same memory, same review history.

  • Repository archaeology

    Why a line is the way it is — owner history, related issues, prior attempts.

  • Long-horizon agents

    Multi-day repository agents with deterministic memory and explicit checkpoints.

  • Audit & provenance

    Every commit signed by the agent ID, the model version and the capability grants that produced it.

Agents at play

The specialists in the mix.

Aether coordinates these specialised agents for the workloads above. Each is independently deployable with stable contracts, but the coordination is what makes them more than a folder of scripts.

AI scientists, not chatbots

Aether does the software & sre work.

We aren't building a chat surface over your existing tools. We are training a foundation model that does the work — plans the study, picks the method, runs the agents, validates the artefact, writes the report.

  • 01

    Plans the study

    Decomposes a one-sentence brief into a DAG of agent calls and posts the plan for your approval before any compute runs.

  • 02

    Picks the right method

    Knows when one solver suffices and when a more expensive one is required. The judgement of a senior practitioner, encoded.

  • 03

    Runs the work

    Dozens of specialised agents execute the plan in parallel. Long runs check-point. Reversible patch sets if anything has to be undone.

  • 04

    Validates against reality

    Cross-checks every artefact against the regression suite for that discipline: published benchmarks, your historical data, customer-validated studies.

  • 05

    Writes the report

    Signed memos with figures, tables and the model-version hash. Ready for design review without rebuilding the deck.

  • 06

    Improves itself

    Failed cases enter the eval corpus. Successful pilots become regression tests. The model your next study uses is better than the one this study used.

Already shipped

The things Aether has already done here.

Not a roadmap. Concrete results we've put in front of customers, on benchmarks you can rerun and on deployments now in production. Each one names the work, the number and where the receipts live.

  • 01

    Every vendor adapter

    The same agent across every IDE and hosted-agent surface. Same memory, same review history.

  • 02

    Whole-repo planned edits

    Reversible patch sets across many files. Cross-file invariants checked before the diff lands.

  • 03

    4× PRs per engineer

    Median across pilot teams. Reclaimed time goes to the parts engineers do best — design, debate, taste.

  • 04

    Cross-language migration

    Semantic-equivalence proofs across six target languages. Legacy systems moved without rewriting by hand.

  • 05

    CVE-aware review

    Vulnerabilities caught at PR time with the patch suggested in-line. Zero critical CVEs shipped on the pilot repos.

  • 06

    Long-horizon agents

    Multi-day repository agents running with deterministic memory and reversible checkpoints in production.

How a pilot works

Eight weeks from scope to signal.

We pilot first, always. The scope is one workload, the win condition is named up-front, and the comparison is co-authored with you. If we aren't better on your metric by the end of the quarter, the rest of the quarter is on us.

  1. 01Week 0

    Scope

    We sit with your engineers, name the workload that hurts, agree the comparison data, the boundary the model runs inside, and the metric we will be measured on.

  2. 02Weeks 1–2

    Stand up

    Aether deploys into your environment of choice — managed cloud, your VPC, on-prem, or air-gapped. We connect to the data we agreed on; nothing else.

  3. 03Weeks 3–6

    Run side-by-side

    Aether runs the workload in parallel with your incumbent. Every artefact carries the model version that produced it. You see every trace.

  4. 04Weeks 7–8

    Comparison

    We co-author the comparison memo. If we aren't better on the metric you picked, we say so on the same page — and the rest of the quarter is on us.

  5. 05Quarter 2+

    Production

    Production deploy with eval-gated promotion, on-call coverage, change management aligned to your release calendar. The pilot's traces become the regression suite.

Compliance & deployment

Built for the regulated parts of the work.

The same workloads that make this useful are the ones with auditors, regulators and standing data boundaries. The platform is designed for that — not retrofitted for it.

  • Deployment

    Managed cloud (SOC 2 Type II), your VPC with private networking, on-prem on your hardware, or air-gapped behind a regulator's boundary. Same runtime, your perimeter.

  • Data residency

    Customer-VPC and on-prem deployments keep training and inference inside the boundary you set. Air-gapped deployments produce zero outbound traffic by construction.

  • Audit

    Immutable per-run traces. GxP / 21 CFR Part 11 / ALCOA+ patterns where the regulation applies. Exportable as OpenTelemetry, SIEM events or JSONL.

  • Provenance

    Every output is signed by the model version that produced it. Promotion through eval gates is recorded; old versions are reproducible by hash.

  • Capability gating

    Every tool call is gated by an explicit capability the model has to request and your policy has to grant. The refusal corpus is versioned alongside the model.

  • Export & IP

    ITAR-clean compartments, export-control gating, separation of duty. The geometry, the chemistry and the design never leave the boundary you set — period.

FAQ

The questions we get most often.

If yours isn't here, send it to hello@apexworldlabs.com and we'll answer it in plain language — usually same day.

  • What does Aether replace in software & sre?

    The incumbent stack here — Editor-embedded coding assistants, Long-horizon hosted coding agents, Hosted PR-review automation, Open-source autonomous agents and more. Aether collapses them into one model and one project file, with Aether for software and Aether for drug discovery doing the work under one safety story.

  • What outcomes should we expect?

    In software & sre: 15 (vendor adapters); +18% (PR merge velocity); −42% (review-cycle time). Scoped to your workload and measured against your own acceptance criteria, not a public benchmark.

  • How is this different from a copilot?

    A copilot suggests text; Aether does the work. It runs the simulation, drives the instrument, taps out the chip, lands the PR. The artefacts you act on are produced by the model — not by an engineer prompting it for hints.

  • Do you wrap an existing LLM?

    No. Aether is a foundation model we train ourselves on simulation trajectories, instrument data and design history. We don't call third-party chat APIs as part of the product.

  • What does the pilot cost?

    Pilots are scoped to a specific workload and a specific win condition. Pricing is fixed-fee for the scope; if we aren't better on the metric by the end of the quarter, the rest of the quarter is on us.

  • Will it work with our existing data and tools?

    Yes. Aether reads the formats your team already uses, runs alongside your incumbent stack during the pilot, and integrates with the data system you already trust. We don't expect anyone to throw away ten years of tooling on day one.

  • How fast is integration?

    Stand-up is typically two weeks once we've agreed scope, data and boundary. Faster if you're already in our supported deployment topologies; slower for sovereign/air-gapped environments where the security review is the long pole.

Bring Aether into your software & sre workflow.

Send us the workload that hurts. We'll come back with a scoped pilot — three to eight weeks, win condition defined together.
