OpenAI's GPT-5.6 models (Sol, Terra, Luna) received refreshed bundled instructions and an increased context window to 272,000 tokens, coinciding with an HN story about GPT-5.6 closing a 30-year gap in convex optimization.
READY TO POST:
looks like openai's gpt-5.6 sol, terra, and luna just got a context window bump to 272k tokens and updated instructions. pretty wild.
hearing whispers about gpt-5.6 making a big splash in convex optimization, while openai refreshes its bundled instructions and expands context to 272k. interesting timing.
