Teknium updated Hermes Agent to expand the token budget available to ChatGPT and Codex subscription users. This update sets the context limit to 900,000 tokens, which exceeds the previously observed 360,000 token ceiling for subscription accounts.
The developer had previously restricted the tool's window to 350,000 tokens to align with subscription limitations for Codex. The new limits were applied following a change that extended long-context support from API keys to standard ChatGPT accounts.
