v2.0.1 — max_tokens clamping

on GitHub

What's New

Provider-specific max_tokens clamping — prevents request failures on providers with hard output token limits.

The Problem

Claude Code sends max_tokens: 16384+ by default (Anthropic's limit). DeepSeek's native API rejects any request with max_tokens > 8192, causing silent failures.

The Fix

The proxy now automatically clamps max_tokens to the provider's hard limit before forwarding:

Claude Code sends:  max_tokens: 16384
Proxy clamps to:    max_tokens: 8192  (DeepSeek limit)
Upstream receives:  max_tokens: 8192  ✓

Details

• providers.js: new maxOutputTokens field per provider (DeepSeek: 8192)
• sanitizeRequestBody() now accepts opts.maxOutputTokens for clamping
• OpenRouter has no cap (OpenRouter handles limits internally)
• No clamping when value is already under the limit
• Backward compatible — opts parameter is optional

Tests

118 tests (99 unit + 19 integration), all passing.
