Build, review, and ship
software — autonomously
Veles is a Fable-5 × DeepSeek hybrid agent that lives inside Reasonix. It plans, architects, codes, verifies, and remembers — an entire software engineering team accessible with a single command.
Average cost: ~$0.001 per task — a fraction of a cent
Overview
Fable-5 software,
designed for Reasonix & DeepSeek
Veles is built on Fable-5 — a forked and customized multi-agent framework originally developed by Anthropic. It orchestrates a team of specialized sub-agents (Architect, Coder, Verifier, Memory) powered entirely by the DeepSeek v4-pro API, all operating within the Reasonix host environment.
The design philosophy is simple: Reasonix handles creative strategy and complex reasoning with full context. Veles is invoked on call for structured, verifiable tasks — code review, quality audits, autonomous fixes, and project bootstrapping. Together, they form a complete software engineering pipeline that is fast, cheap, and evidence-backed.

How Veles works
Every project follows the same three-phase pipeline:
Bootstrap
veles new <project> creates the directory, configuration, and seeds memory. Then Reasonix builds the creative work — full websites, dashboards, reports — using the skills catalog.
Enhance
veles design <project> invokes the Architect, which reads the codebase and proposes concrete, code-ready improvements. Reasonix implements them.
Ship
veles verify <project> runs the Verifier — a PASS/FAIL audit with evidence. Fix any FAIL items, then push to deploy.
The two-model system
| Mode | Model | Speed | Cost | When Active |
|---|---|---|---|---|
| Reasonix (default) | DeepSeek v4-pro | Slower, deeper | Standard | Always — strategy, creative direction, full builds |
| Veles (on call) | DeepSeek v4-pro | Fast, powerful | ~$0.001 / task | Explicitly invoked — code review, verification, sub-agent tasks |
Capabilities
What Veles can build
Veles has been production-tested across dashboards, websites, reports, and interactive visualizations. Every output meets H Heuristics' professional-grade quality standards — pixel-perfect, accessible, and client-ready.
Professional-Grade Websites
Multi-page or single-page sites with responsive design, dark/light themes, CDN-optimized. Economist aesthetic, system font stacks, zero-build deployment.
Interactive World Map Dashboards
Folium-based or Chart.js-powered interactive maps with choropleth layers, regional drill-downs, KPI overlays, and data filtering.
Market Intelligence Dashboards
Executive dashboards with KPI cards, bar/line/doughnut charts, sortable tables, regional breakdowns, and investment analysis. Self-contained HTML.
Comprehensive Reports
Data-driven PDF reports (5+ pages) with title pages, executive summaries, data tables, policy recommendations, and professional typography.
Sub-agent roles
| Agent | Access | Purpose | Speed |
|---|---|---|---|
| Orchestrator | Delegates only | Plans task, delegates to sub-agents, summarizes results | 30–90s |
| Architect | Read-only | Explores codebase, proposes concrete improvements | 5–15s |
| Coder | Full R/W | Implements changes, writes files, runs commands | 5–30s |
| Verifier | Read + Execute | Audits quality, runs tests, returns PASS/FAIL with evidence | 10–30s |
About
The economics of autonomous software engineering
Traditional software development is expensive. A senior engineer costs $100,000–$200,000 per year. An agency project runs $10,000–$50,000. Code review alone consumes 4–6 hours per week per developer. Veles changes this equation.
"Veles costs ~$0.001 per task. A full autonomous pipeline — Architect design review, Coder implementation, and Verifier audit — costs less than a single minute of a developer's time."
Cost comparison
| Activity | Traditional Cost | Veles Cost | Savings |
|---|---|---|---|
| Code review (per session) | $75–150 | ~$0.001 | 99.999% |
| Quality audit (per project) | $200–500 | ~$0.002 | 99.999% |
| Full project bootstrap | $500–2,000 | ~$0.005 | 99.999% |
| Autonomous fix pipeline | $150–400 | ~$0.003 | 99.999% |
Traditional costs based on average senior developer hourly rate of $75–150/hr. Veles costs are API-only (DeepSeek v4-pro token usage). Does not include Reasonix subscription.
Annual savings projection
For a team running 10 code reviews per week, 2 quality audits, and 1 project bootstrap per month, the annual comparison is stark:
| Traditional | Veles | Saved | |
|---|---|---|---|
| Code reviews (520/year) | $39,000–78,000 | ~$0.52 | ~$58,500 |
| Quality audits (104/year) | $20,800–52,000 | ~$0.21 | ~$36,400 |
| Project bootstraps (12/year) | $6,000–24,000 | ~$0.06 | ~$15,000 |
| Annual Total | $65,800–154,000 | ~$0.79 | ~$109,900 |
"Veles saves approximately $110,000 per year in avoided developer time — for less than a dollar in API costs. The economic case for autonomous agent pipelines is no longer theoretical."
Built by H Heuristics
Veles is maintained by H Heuristics, a market research and economic development consulting firm based in Nottingham, UK. It powers the firm's own production pipeline — every dashboard, report, and website published by H Heuristics passes through the Veles verify step before deployment.
The name Veles draws from Slavic mythology — the god of earth, water, and the underworld, associated with craftsmanship and trickery. An apt namesake for a system that builds, reviews, and verifies with equal fluency.
