Training & availability
Training data has a knowledge cutoff of 2024-10-31 — information about events after that date is unlikely to appear in the model's responses. Anthropic has not released the underlying model weights — access is via their hosted API only.
Capabilities
-
Context window: 200K tokens.
-
Max output: 64K tokens.
-

max_tokens=1024,
messages=[{"role": "user", "content": "Explain quantum computing in one sentence."}],
)
