Best Gemini 2.5 Pro alternatives
Users may seek alternatives to Gemini 2.5 Pro because of its higher latency on very large multimodal inputs and dependency on Google infrastructure. This list covers seven multimodal models with their intelligence indices, speeds, prices, contexts, strengths, and limitations relative to the base model.
GPT-5.4 Nano offers a higher intelligence_index of 44 compared to 34.6 and a lower price of $1.25 per 1M tokens versus $10, with similar output speed, but its 400k context is smaller than 1M and it lacks audio or video support.
GPT-5.4 Mini provides a higher intelligence_index of 48.9 and faster output speed of 183.23 t/s versus 143.97, at a lower price of $4.5 per 1M, though its 400k context is smaller and it may reduce depth on complex reasoning.
Gemini 2.5 Pro Preview 06-05 matches the 1M+ context and $10 price but adds native support for audio and files with solid reasoning performance, trading off potential instability in this preview release.
Claude Sonnet 4.5 matches the large context size near 1M tokens with strong safety alignment and reliable large-context handling, at a higher price of $15 per 1M, though it can be overly cautious with refusals.
Gemini 3.1 Flash Lite Preview delivers much faster output speed of 312.36 t/s versus 143.97 at a lower price of $1.5 per 1M with the same 1M context, but its lite design trades depth for efficiency and may show inconsistent preview behavior.
Grok 4.3 achieves a higher intelligence_index of 43.9 at a lower price of $2.5 per 1M with a 1M context and real-time tool access, though its vision capabilities are less mature than specialized models.
Claude Opus 4.8 has a much higher intelligence_index of 61.4 with a 1M context and strong multimodal integration, at a higher price of $25 per 1M, but it shows higher latency on large contexts due to safety tuning.
OpenAI multimodal model with 400k-token context for text and image tasks.
