Get $200-Tier Coding Capacity for $100 + $29 Oxyo.

Pairing Claude Code, OpenAI Codex, Cursor, or Gemini with Oxyo (oxyo.si) cuts 5-hour and weekly quota burn by 60%–72% (2.5×–3.6× effective coding capacity) — backed by 7.7M–12.4M managed standalone tokens, $0 unlimited MCP calls, and 100.0% (23/23) live deterministic Python verification.

💰 Verified Subscription Math: Stop Overpaying for 5-Hour Quota Resets

Measured with tiktoken on a 112,247-token production repository (see full methodology & interactive calculator on oxyo.si/best-use): connecting https://oxyo.si/mcp to your coding agent eliminates repetitive repo re-reading and stale-spec debugging loops, while Oxyo Standalone (oxyo.si/app) offloads live web research and file audits at zero cost to your IDE quota.

Why Token Burn Drops by 60%–72% (Prompt-Cache Adjusted)

1. Surgical MCP Recall ($0 LLM Burn): Instead of burning 6 exploratory turns (35,000+ tokens) re-scanning files after every /clear, branch switch, or new IDE window, one oxyo_session_pack / oxyo_recall injects active project rules, ports, schemas, and causal root causes in ~350–600 tokens (~110 ms).

2. Offload Non-Repo Work to Oxyo Standalone (7.7M–12.4M Managed Tokens Included): Run 🌐 Live Web searches, documentation lookups, screenshot (Ctrl+V) visual inspections, and CSV / Excel / PDF / ZIP audits directly inside oxyo.si/app or the Windows Desktop App (.exe) — burning 0 tokens from your shared 5-hour Claude Code / Codex / Gemini pool.

3. Deterministic Python Verification Instead of 5×-Weighted CoT Guessing: Execute multi-currency Decimal math, reconciliations, combinatorics, and formal constraint proofs deterministically via oxyo_verify_python & oxyo_prove_constraints on the first pass instead of burning reasoning quota on trial-and-error loops.

🧬 Why Oxyo Beats Standard AI (O · XY · O Informational DNA)

Stop paying in time, quota lockouts, and broken code to re-explain your architecture every morning:

• 0× Context Re-Pasting — Open a fresh session 6 months from now (or jump from browser to Cursor to Claude Code) and Oxyo already knows your stack, schemas, and invariants.

• −90% Wasted Prompt Bloat — Standard chats re-transmit 50k–200k old tokens per turn ("context rot"). Oxyo retrieves only surgical, contradiction-free memory in milliseconds.

• 100% Contradiction-Free & Executed — Outdated rules are superseded automatically when specs evolve (Strand X), and math/logic is executed in an isolated zero-network Python sandbox before replying (Strand Y).
