GPT-6 Astra (Ücretsiz) - access through LLMTR
The free, daily-quota version of GPT-6 Astra, open until 10 September 2026. After that date this identifier stops accepting requests and the error you receive suggests the metered GPT-6 Astra row; nothing switches over on its own — you change the model id yourself, and until you do, nothing is charged. Use it for complex reasoning, agentic coding, research, and document production; it offers a 1.05M context window, text and image input, tool calling, JSON output, and five reasoning effort levels from low through max. It is called through the chat completions endpoint only, accepts no PDF input, and caps a single response at 128,000 tokens. When the quota runs out, the error you receive states when you may retry. Use the metered row when you need continuity, PDF input, or a higher output ceiling.
