Greptile Overview

Summary

Added comprehensive Mistral AI provider integration and updated model pricing across multiple providers.

Key Changes

• Integrated Mistral AI with 10 models (mistral-large, magistral-medium, mistral-medium/small, open-mistral-nemo, codestral, ministral variants)
• Added tool usage control support matching xAI implementation pattern
• Updated pricing for Anthropic (added claude-sonnet-4-5, claude-opus-4-1), xAI (added grok-4-fast variants, grok-code-fast), Cerebras (added llama-4-scout), and Groq providers
• Integrated provider across configuration, tokenization, and type system

Implementation Quality

The Mistral provider follows established patterns from xAI and OpenAI providers using OpenAI SDK with custom baseURL. Implementation includes:

• Comprehensive tool calling with forced tool support
• Streaming responses with usage tracking
• Detailed timing metrics and iteration tracking
• Proper error handling with timing metadata

Issues Found

• Commit title has typo: "mistal" should be "mistral"
• Uses @ts-ignore at line 552 (style issue per custom rules)

Confidence Score: 4/5

• This PR is safe to merge with only minor style improvements needed
• Score reflects solid implementation following established patterns with comprehensive testing coverage. The only issues are a typo in the commit title and one style violation using @ts-ignore. All core functionality is properly implemented with tool usage control, streaming, error handling, and proper integration across the codebase.
• No files require special attention - all changes follow established patterns
