GitHub Models service retires, ending unified LLM API access

GitHub has permanently retired its Models service, which previously offered a unified API interface to access multiple LLM providers. The service had allowed developers using GitHub Actions to leverage the GitHub API key for cost-efficient LLM calls. While GitHub has not officially disclosed the reason for the shutdown, the discontinuation aligns with industry-wide cost management trends as coding agent usage patterns have driven token expenses significantly higher for free or subsidized LLM services.
