PGS AI Coding Plan (Phoenix Grove API) — Free First Month
Phoenix Grove Systems
Taster tier: first month free with two lightweight models, DeepSeek V4 Flash 0731 and GLM 5.3 Flash — 18M+ Flash tokens/month; bills $3.99/month starting month two, cancel anytime
The Coding Plan shares one allowance with the PGS AI app — one subscription covers both. Usage refreshes on a rolling 5-hour window, and whatever you don't use banks up automatically for up to 10 days (it doesn't reset daily). Your key speaks four protocols: OpenAI Chat Completions (/v1), Anthropic Messages (/anthropic, for Claude Code), OpenAI Responses (/v1/responses, for Codex), and the Ollama protocol (/api) — just swap the base URL and key into your existing tools. Paid tiers (Basic, $12.95/month and up) unlock more models (GLM 5.3, DeepSeek V4 Pro, etc.), bigger allowances, and more parallel agents (3 on Basic, up to 8 on Canopy); the free Taster month only includes the two lightweight models above.
Official copy: "Bills $3.99 a month after. Cancel anytime. One free trial month per person, duplicate trial accounts will be canceled." The free first month is a standing acquisition offer, not a time-limited campaign — but it auto-bills $3.99/month starting month two unless you cancel yourself in the dashboard. Whether a payment method must be attached at signup wasn't independently verified (we didn't complete an actual checkout); confirm before claiming so you don't forget to cancel. The homepage banner copy ("FREE MONTH OF DEEPSEEK V4.1 FLASH + V4 FLASH 0731 + GLM 5.3 FLASH") doesn't quite match the body copy ("two lightweight models") or the Taster card's own model list — the banner appears to list an extra model name. This entry follows the Taster card's list: DeepSeek V4 Flash 0731 + GLM 5.3 Flash.
